Speaking of the speakers, especially the slightly better speakers, the words that populate the brain in most people's minds for the first time must be “black and hard, silly and thickâ€. Under normal circumstances, the better speakers, the more interfaces behind you, you need to understand the connection of various audio input and output lines, which must have been too many people. Wire, in the hearts of players playing HiFi, must have occupied a very important position. . .
So, the problem is!
So many lines, too messy, how to do? !
I just bought a new house and installed a video room. What should I do?
I am a sister, love listening to music, watching a bunch of headaches, what should I do?
The most important thing is that I am a Virgo. What should I do? !
Do I have to become self-taught to become a female man?
Do I have to spend a lot of money to reserve wiring in advance of the renovation?
Can't I just endure the floor line?
OK, OK, OK, let me tell you! What you need is ----- wireless!
Then the question came again, what's in it, what do you want to say?
Here are my grand report objects:
SONOS PLAY: 1+ SONOS BRIDGE Wireless HiFi Sound System
To be honest, before the public test, I only knew a little about Sonos's brand of speakers. I only knew that Sonos focused on wireless speakers for more than a decade and was considered a high-end speaker brand. After the successful testing of the public applications, a large amount of information was consulted and a more in-depth understanding of it was obtained. There is a paragraph on the Internet that says: SONOS often looks like an unreasonable thing to people in the industry, such as never buying spare parts, all parts are produced by themselves; abandon industry standards, and use more stringent internal standards Wait. So far, SONOS has won nearly one hundred honorary awards and more than 200 industry patents, and has consistently ranked in the leading position of the wireless intelligent HiFi audio industry.
Sonos actually has a range of products, including Sonos Play1, Paly3, Play5, PlayBar, Sonos Connect:amp and Sonos Connect. However, sonos play1 is not officially listed in the country.
Now let's take a look at a little news, hoping to help you better understand the development of the brand sonos in China.
On October 10th, 2014, SONOS, the second-largest brand in the world's audio industry, SONOS, today hosted the “Happy House†brand conference at the Yiheng Hotel, Beijing's fashion and cultural landmark, marking its formal entry into the Chinese market. As the founder of the global wireless intelligent HiFi audio, SONOS will bring a revolutionary music listening experience to a large number of Chinese consumers. On the same day, the famous singer Mr. Hu Haiquan, the global vice president of Tesla Tesla, Ms. Wu Biyi, the founder of geek park Mr. Zhang Peng and the president of SONOS China Dr. Wang Hanhua had a brilliant discussion on the origin of smart audio and the development of the industry. Home media and representatives from SONOS China Music Partners attended the event.
Wireless control, multi-room expansion, massive music, and HiFi sound quality are some of the most revolutionary features of SONOS products. The two classic products unveiled at this launch event are SONOS PLAY:3 that can be placed horizontally or vertically. And SONOS PLAY:5 for more space and more shocking effects. 
However, this conference did not release sono play1 as expected. Then I will introduce paly1 in detail! The two small boxes in the figure below are play1. Head is very mini, simple shape.
Sonos Play:1 is currently the smallest and cheapest speaker from Sonos.
Sonos play1 specific parameters specification features:
1. Control by computer, smart phone, tablet running sonos app
2. Can be used alone or as a stereo pair, if you have more sonos you can also combine surround sound
3. 1-inch tweeter
4. 3.5-inch bass unit
5. Can be wall-mounted
6. Dimensions 163 x 119 x 119 mm
7. Weight 1.8kg
8. Waterproof, can be used in the bathroom
Below, start my evaluation.
Unpacking and appearance
According to convention, firstly like the packaging picture. When I just got the courier, I looked at this huge box and it was far beyond my imagination and it was very heavy. At the beginning I couldn't understand why the two small speakers were so extravagant. The lower right corner is a comparison of the box and a chair, which shows how big this size is.
After opening a public notice, there are two cartons. There are two sonos paly1 in the big one, and the sonos bridge in the small one. 
Everything is taken out of it! The following introduces bridge and play1 separately.
Sonos bridge appearance
Packing box
Internal items, including instructions, bridge body, network cable and power supply. It is worth mentioning that the cable is a flat cable and it is very rare.
Ontology. Milky appearance, very fine workmanship, only one button, behind the two cable interface and a power connector. The soft rubber on the bottom is very comfortable and exquisite. The shock absorption is very good. 
Sonos play1 appearance.
The highlight is naturally to introduce play1.
A pair of play1, box, black background, purple pattern, white logo. Are the two boxes of patterns spliced ​​together to look good?
Items in the box. Manual, warranty card, speaker, power cord, network cable. The cable is still flat, and it is well received.
The speaker is wrapped in a flannel cover to prevent scratches. The first impression of taking out the speakers is: Shen! Heavy!
Open, the speaker is like this. The speaker is my favorite white, I think it is much more beautiful than the black play1
One on the map and one on the real shot. The box is wrapped in a large area of ​​stainless steel net cover, completely seamless. There is only one fixed screw connector on the back of the cable connector. The bottom is the power connector.
Upper close-up, simple three buttons, one indicator light. Different colors of the lamp can represent different states of the speaker. Under normal conditions, the light is always white.
If you do not like light, you can turn off the light in the software settings. Sonos's pursuit of detail is evident. At least I have not seen which speaker can freely control the light on and off.
Net cover comes close-up. Very smooth, no burrs. The entire net cover is seamless, without any seams. The net cover will not deform when pressed hard by hand. There should be support material inside, and there is no need to worry about the deformation of the net cover or the damage of the bear or the child. Workmanship 5 stars, material 5 stars, safety 5 stars! 
I'm full of endless interest in paly1's power interface. For no reason, a simple design. Slit, beautiful. There will never be a loose connection to the power interface.
Screw connectors, and special mounting brackets make it easy to mount the speakers on a wall or stand.
In short, whether it is a bridge or play 1, the workmanship is exquisite and excellent. The plastic part and the rubber pad are delicate and smooth, and the metal mesh cover is delicate and burr-free and thick enough. The speaker material is full, from the weight can obviously feel. After seeing my pair of sonos, the two little girls who didn't understand the HiFi headphone speaker, got it and got it right away. They came up with a conclusion: The workmanship is really good and it must be a good speaker.
Connect and use
Before starting this part of the content, let me talk about the wifi connection used by Sonos. There are two common wireless speaker connection methods: Bluetooth and wifi . Bluetooth is more common, but the disadvantages are obvious: 1 distance is not far enough, 2 is susceptible to interference, 3 transmission rate is limited. The advantages of wifi are clear at this moment, and all these shortcomings can be solved.
I think that there are very few evaluations of speakers that will explain the connection method separately. However, for Sonos, it is necessary to say something special because it is the brand's soul of Sonos.
First of all, it is very important to install sonos own control software on your computer or mobile phone or your tablet, because leaving the software, your sonos can not put out sounds.
When I first installed the software, I encountered a minor problem. When I downloaded the link from the official website and chose the Android version, the software download address came from Google's market and Amazon's market. I then specialized in climbing the wall. . . Then suddenly thought why not find those software markets in the country to download it? A search really happened, so the installation was smooth.
Computers, mobile phones, and tablets are all successfully installed and the client software is ready to connect speakers. The process is very simple and convenient. Just follow the prompts and continue with the next step. It is worth mentioning that when the new system was added at the beginning, there were two schemes, bridge and standard setup. If you use a bridge, then select the bridge connection. If not, select the standard connection.
At the beginning, he took out a play1 for auditioning. It felt like the sound quality was good and it was good. Later, it was found that two speakers could be combined together to form a stereo pair, and this function was tried for the first time. After the combination was completed, it was greatly amazing. It is not an exaggeration to say that the overall sound quality has been improved.
Here's a stereo pair of two play 1s, the official speaker placement. Two speakers are best placed at 8-10 feet, which is a distance of 2.5-3 meters. The listening position is best with two speakers in an equilateral triangle. This will give you the best listening experience. Obviously, play 1 is used for your room, not your computer desk. 
Before the stereo pair was created, Sonos' software can control two speakers to play different music at the same time (this is useful if your house is big enough and you want to enjoy different music in different rooms). Volume track switching can be done separately.
After being combined into a stereo pair, the two speakers become the left and right channels. The great thing is that no matter whether you adjust the volume or other operations on the software or the speakers, the two speakers are all seamlessly synchronized, and you feel completely uncomfortable. To delay.
In the software, you can also set a simple balance for the speakers. For example, if you like bass, you can turn up the bass and you can turn down the volume that you don't like.
This is the playback interface for the sonos mobile client. The first screen shows the album cover, song information and volume track adjustments. After clicking the red circle, a new playback interface appears, which can quickly adjust the progress of the song. At the same time, more options are available, including adding playlists, favorites, searches, other album information of the performers, albums and other songs on the album, and so on. They are all fools. One-button operation, very very convenient.
This is the computer's client interface. We can see a lot of music services on the right side. Now domestic shrimp, watercress, Netease cloud music, qq music, and so on have been and sonos cooperation, the same many domestic radio station resources can also be found in the sonos. In foreign countries, there are even more resources than you can imagine. Tens of thousands of radio resource providers are waiting for you to discover. Of course, these resources can be found in mobile phones or tablet clients.
During the use of Sonos, I happened to find that when I withdrew the mobile client, Play 1 did not stop playing the music , but continued. When a track is finished, it is also possible to automatically play the track according to the playlist I previously set. This caused me a great deal of interest. To take an inappropriate view, it seems that the sonos client and the speaker are not connected in a "series" way, but in a "parallel connection" mode. Well, this means that the play 1 itself must have a separate set of storage and wifi management chips. In order to verify my idea, I went to check the information again. So I found the following:
SONOS not only comes with a DSP circuit to improve the sound quality, but also uses the highest specification of download and playback. In fact, after using skilled, you will find the logic of SONOS is this: You do not need to download music, just create a song list, play SONOS before The songs are pre-cached to the speaker's memory in the highest specification (yes, SONOS speakers have memory). To this end, I also asked about QQ music, usually QQ Concert offers songs from different 192-320kpbs sound quality for online audition or download, and if you connect SONOS, whether your music is downloaded to the phone, SONOS will automatically call the highest The audio of the specifications is played online. This is why the premise of building SONOS is that your home must have a good network environment.
In my usual use, I discovered that when sonos use online songs such as shrimp or Netease Cloud Music, the speed requirement is not particularly high, and they can all play smoothly. Even if I use the Tmall box to watch high-definition movies online at the same time, there is no problem at all. However, once switched to play local lossless music, sono’s demand for bandwidth immediately soared. Often because of the wireless signal is not good enough (my router and play 1 not in a room, the signal is not full of grid) leads to the playing card. At this time, the role of the bridge is highlighted. After using the bridge, the phenomenon of insufficient network connection speed has not appeared again.
To sum up, wireless is really a bunker! Convenient, non-interfering, non-stopping, no distance restrictions, lying in bed, just picking up your phone, searching for songs, playing, switching, really do whatever you like. Sonos connection is very convenient, fool-style operation, the first time you connect, follow the prompts next step next minute can not be completed. Then open the client and connect directly. The software of multiple clients can be completely seamlessly synchronized. For example, switching songs on the mobile phone side, then the computer display and the on-screen display immediately switch to new songs, which is very comfortable.
However, there is a more fatal problem. I also said at the beginning that if you want to play 1 sound, you must go through sonos' own client. This results in the limitation of speaker signal input. For example, the software does not support the APE format. For example, you cannot use sonos play 1 to watch movies! ! ! In other words, if your home has only sono play 1, you can only use it to enjoy music. If you want to use it as a TV speaker under a TV or watch a movie on a computer, I'm sorry, no way! Presumably this will stop a lot of people who play water 1 play, after all, to spend a lot of money to buy a speaker that can only listen to the song, it feels like it was the same, is not it. . .
sound
Special thanks: This section is especially grateful for the unselfish guidance of the Fat Fat Master @. After communicating with the fat master spirit and meat, I have a deeper and clearer understanding of the sound quality of Sonos Play 1.
(Saying a digression, this report of the sonos play 1 is one of the most painstaking and hardest ones I have ever written. I was struggling with my brains for fear of misleading or jesting because of my unprofessionalism. To this end, I read a lot of information and found a lot of relevant content, consulted professionals, and the public report was delayed for more than one week. . This part of the voice is the place where I have devoted the most effort. I hope to do my best to bring you the most rigorous and objective evaluation. )
Sound is the soul of the speaker. No matter how exquisite and beautiful the speaker is, the sound quality is very bad, so it can only be a soaring.
Many people say that playing HIFI is metaphysical. Although this is a ridicule, it also has some truth. The sound is influenced by subjective factors. Some people like to rock and some like vocals. Speakers of different sound styles are sure to get different evaluations in different people's ears. Let's speak with data first.
Sonos play1 frequency response curve
This frequency response chart comes from American audio expert Brent Butterworth, which may be the only frequency response graph for the only sonos play1 available on the entire network. The expert obtained this frequency response curve through a complete laboratory measurement of Sonos and gave Sonos Play1 a very high rating. However, because the comparison results of other people's evaluation results were not found, this figure is for your reference only, and it is not recommended to be considered authoritative. The following content is partially translated from the content written by Brent Butterworth. If any professional term translation is incorrect, please correct me.
The blue curve in the figure is the test result at the axis 1 meter away, and green is the average response curve at the ±30° horizontal position. Generally speaking, the smoother the blue line, the better. The closer the green line is to the blue line, the better. The curve shows that the blue line fluctuates at ±2.7 dB and green ±2.8 dB. This means that play1 performs very well whether it is horizontal to the unit position or ±30°. That is, no matter where you are in the room, the sound of play1 you hear will be very pleasant. (However, we can obviously see a large fluctuation of 5dB at about 130Hz. I don't know if it is "averaged" or ignored?)
The low frequency of the foreigner's special book, sonos play1, "it can reach 88Hz at -3dB, which is excellent for such a compact speaker. It can even match most of the 4.5 foot woofer that I have tested. It seems that Sonos should have done a lot of work on this 3.5-inch bass unit in order to make its dive to such a depth" (but according to @ pretending fat fat master, online evaluation, KEF X300A frequency The ring curve shows that the X300A doesn't reach this value at -3dB, but it actually sounds like KEF's bass is definitely better than paly1, so the result of this play 1 is yet to be verified - is it due to differences in the test methods? )
The foreigner finally gave a few highly rated conclusions: the frequency response of the sonos play 1 can be compared with a pair of floor boxes of 3,000 US dollars. Objectively speaking, the deviation of any one speaker can be within ±3.0 dB, which is "excellent". The current wireless speakers - and even any other small speakers - rarely have any performance beyond the paly 1's sound quality.
The foreigner praised sonos play 1 is a mouthful of praise, this foreigner is not reliable I do not know, but the current domestic media on the play1 some evaluation, we have the overall quality of the speaker is also acclaim.
My sense of hearing
The data is cold and the sense of hearing is real. No matter how good the data is, you have to listen to it. Let me talk about my own feelings.
First of all, say a vocal, Huang Xi's "listen to sand." The first time I played this song with play 1 was on a quiet night. When the song rang, I was shocked to tell the truth. The first few captions were just like the singers standing in front of my eyes and singing to me. Lips and teeth can even feel the sensation of a fully disengaged speaker until the music sounds. Praise.
Seismic low-frequency killer drum. Regarding low frequencies, first of all, we must remember its small size and then evaluate the performance of play 1. I can say so, the low frequency of play 1 can be said to be amazed! The shocking feeling that the drums gave you when you sounded is really beyond imagination. It's like standing alone in a vast field, surrounded by immense silence. At this time, the sudden sound of a big drum brings shock to your heart, just like percussion. In your heart. But this kind of play 1's shocking low-frequency is not simply for the low and low, elastic and full but not turbid.
Violin has always been the best instrument for testing high frequencies. I chose the famous solo violin solo song "The Song of the Homeless" to try out the treble. Play 1's high-frequency slender and soft, not harsh, solution power is very good, more space sense, can be a good performance of the kind of noble vigor and smooth sweet sound characteristics.
In addition, Tsai Chin's "River", "Forgotten Times", and "The California Hotel" by the Eagles, I also listened to the soundtrack. Tsai Chin's mezzo-sopranos are well-interpreted in play 1, and the low-pitched noises that sound beautiful are very magnetic. The opening accompaniment of a California hotel can make people feel as if they are on the scene. The sense of unpacking is obvious. However, the spatial orientation of different musical instruments seems to be somewhat inadequate. Some musical instruments cannot be clearly identified and the whistle can be distinguished by one ear.
The sound of sonos play 1 must be well-received. The treble is clear, smooth and clean. The details and expressiveness of the sound are full. The bass is shocking and beyond imagination. But I think, for its own positioning and actual performance, sonos is more suitable for listening to pop music. When I listen to symphony with play 1, I always feel that I don't have enough power --- Of course, such two small speakers cannot be too strong.
to sum up
The subject of this review wrote subversive words. This is really what I feel about Sonos. Sonos abandoned the complex and messy cables of traditional speakers, changed the operating mode of traditional speakers, and brought the greatest degree of convenience under the premise of ensuring sound quality to the maximum. This is a subversion of the traditional speaker industry. I believe in the future, the wireless speaker must be a development trend, and Sonos has no doubt been at the forefront. The following general talk about the advantages and disadvantages it up:
advantage:
1 Excellent sound quality. Excellent mid-high frequencies and unimaginable low frequencies make it difficult to imagine such small cabinets.
2 The wireless connection is really amazing. Easy to operate, less limited, less distortion of music.
3 supports lossless playback. Sonos supported music formats are MP3, iTunes Plus, WAV, WMA, AAC (MPEG4), AAC+, Ogg Vorbis, Audible (Format 4), Apple Lossless, Flac and so on.
4 Unlimited online music resource support. Support music alarm clock and other intimate small functions.
5 Excellent workmanship, solid materials.
Disadvantages:
1 Sonos can only use the client's own music player, not open enough.
2 You can't use movies, you can't play games, and you can't use TV! This should be the biggest short board for Sonos Play 1.
3 I can only use it to listen to music; I can only use it to listen to music; I can only use it to listen to music...
4 The price can be cheaper? The United States 199 knives, Taobao 1800 + price single play 1 how to see how far away from China's ordinary family a bit far away.
5 Wireless is not thorough enough. If there is a battery pack that can provide enough power to get the play 1 out of the power cord, it would be even more perfect.
6 I don't know if this is an advantage or a disadvantage: If the sound quality of a single play 1 hits 1 point, then 2 play 1 combinations must be 3 points or even 4 points and 5 points, which is a huge increase. However, this means that you need to double the price. . .
 For the sound quality of the play 1 itself and the wireless operation connection method, I think the sonos has done a very good job, absolutely give praise in this regard. The biggest drawback of this speaker is that it can only be used to listen to music, not to be used as a TV speaker or to play games and watching movies. This is indeed a big regret. (In fact, my list of disadvantages is actually the first three meanings. ..)
It can be said that sonos play 1 has a huge body of energy. Its excellent sound quality is even incongruous with its small size, but its price requires that it must have such a good voice. . For non-fans like me, the sound quality of play 1 has been fully able to meet my needs, and its convenient wireless connection and massive music resources are more able to impress me.
When I go home, when I'm resting on the sofa, when I drink tea and read newspapers, when I whisper with my lover, when I'm cleaning, when I have a candlelight dinner, or even when the toilet pits, I can pick it up. Does mobile phone open sonos, appreciate any wonderful music that you want to hear, and there are more pleasant things than this?

A push button switch is a switch that has a knob that you push to open or close the contacts. In some pushbutton switches, you push the switch once to open the contacts and then push again to close the contacts. In other words, each time you push the switch, the contacts alternate between opened and closed. These types are commonly called latching switches. There are also Non latching push button switches that only maintain the switch contacts when the switch is help in position. Once the switch is let go, the current is broken and the switch turns off. Push switches are usually a simple on-off switch.
