B&O - Danish brand Bang & Olufsen, founded by two young Danish engineers. The design style is concise and succinct, the function is supreme, the innovation is imaginative, it is the typical Nordic style, and can get along well with the home environment. This is the Play series. A9, always wanted to make money on stocks, and the stock was trapped. This pair of speakers, the value of 60w or so, sat and listened to a song, unclear. In recent years, B&O's products have also bought a lot. Look at a part of the family portrait first, and some are not here. Behind is Beoplay A6, Beoplay A2, the front row is Beoplay H3 ANC, Beoplay A1, Beoplay H8. The earliest contact with B&O products was the Beoplay A2. Originally bought several Bluetooth speakers, they were not very satisfied. At this time, A2 was just listed and it was bought by an agent. Looks like a kun package, with a belt. The sound is really good. And its voice and the placement of the angle is not big, vertical, lying, positive, aspect, sounds similar to the use of the factory's unique 360 ​​sound technology. The voice sounds good, thick and not muddy, the midrange has weight, and the sound of human voice is just right. Suitable for jazz and ballads I love to listen to. Electricity is also very good enough, I have not charged for two weeks, listening for a while every day, but I did not accumulate specific time, this post is not technical stickers. According to experience, it is OK to listen to the medium volume for 7 hours. Some people say that I can only listen to 3 hours, small speakers suitable sound should be below 60%, I am afraid that generally about 40%. The bluetooth speaker will break the sound loudest, no one manufacturer would say that my speaker has the maximum volume, and the sound is still good. If you really want to hear a big voice, 300 yuan to buy a square dance rod speakers is also very good. Not black, it is really recommended. When I'm busy with tea, I have a teacup and I drink tea with a teacup when I'm thirsty. The slots are all in one corner, AUX port, USB port (output power, non-charge port), DC-in power port. In addition to listening to songs, A2 can also be used as a treasure. I do not like this feature, the speaker must try every means to sound well, do not need to work part-time charge Po. The second generation of A2 intimately canceled this function. The power input requires a transformer, although it is fast, but it is inconvenient. The second generation of A2 is changed to the data line charging, and the customer will solve the charging head by himself. However, the second generation started with a canvas to replace the leather belt. It's a little small regret, and the forcing is reduced. The latest natural color A2, back to the leather belt. It seems that B&O is really listening to users' opinions. Every step of progress is stepped on. This angle can see a status light, power button, volume plus/minus key, Bluetooth button, simple design. There are a few A2s in my hands, including gray, gray gold, black, navy, and black gold trophies. I think the best color to date is the black gold medal of the generation. Followed by the second generation of natural colors. Now that you can buy a second generation, you don't want to buy one. From the point of view of upgrading a charger, you don't need to buy a generation. Download an official software in mac, upgrade firmware, there will be a better experience. Can also be used with Beoplay, Beosetup, BeoMusic and other software to play together. A2 can be tuned through the app and can be combined to change two channels. Finally, listening to songs via Bluetooth is the easiest thing to do. It is not A9. Also use Sennheiser HD598, HIFIMAN HE400, AKG K701, iron triangle ath-ew9 cherry wood headphones (Queen), etc., want to start with a casual use, do not need to use the amp and HIFI player, direct Plug the phone to listen to the headset. Originally optimistic about the H6 in the agent side, this time the H8 madheartedly listed, with Bluetooth wireless features, with noise reduction, but also can be used as an ordinary headset plug. I didn't take much photos of this headset. But a lot of use, talk about it. The sound is good. After noise reduction, you can clearly listen to music, lectures and comic dialogues on a noisy bus. Listening to the songs at night and listening to the TV is good at night and does not affect others. Right ear earphone has touch operation function. Personally feel no use, up and down song, volume, play pause or use mobile phone operation is more appropriate. The switch noise reduction function is very easy to use, and the fingers can slide down. In the dead of night, when the noise was switched on, there was a bit of current and I thought it was broken. Later, I checked the Internet to find a way to turn off the noise reduction (I rarely read the instructions). When there is no noise, noise reduction is noise, which is a philosophical reality. Better to cancel the right ear touch control, leaving a noise reduction entity switch. The price can be less. I'm very fond of looking at the photo of the official website. The agency ordered 3 more units. Why am I so greedy? In fact, the two were given to friends. The lid is made of aluminum and it is easy to bruise. If you do not care, it does not matter, at least better than plastic. Only deformation will not break. There is also my favorite leather rope, a very solid metal BO round logo decoration. It is a large macarons. At the beginning, there was only one silver. Then it was green. Then it was dark brown. Now it looks like blue. Not sure. I like silver best. The lid can be unscrewed. I opened it with my handcuffs. There was a big black horn and a protective plastic cover. It was nothing to look at. Value-friends try not to handcuffed, and it's harder to go back. The sound was fine, but the difference with A1 came out. The details and mellow feeling and atmosphere, and A2 still had an ear gap. If you don't put AB together with A2, your usual listening is very good. And it's particularly stable, and it's no longer dangerous to play A2 when it's down or knocked down by a child. And much more portable than A2. I describe this portability, so that everyone can better understand that the A2's portable device can be installed in a bag. The A1's portable device can be mounted on the outside of the package. The P2 portable device can be worn in a trouser pocket. Originally should not buy A6, buy it and play A9. Plug in the electric test machine, a big boomerang, but it's really nice. The gray cloth cover is not violated, and the home can integrate naturally. Can hang on the wall can also be placed on the table. However, the rack is expensive and it is not bought. There is a small cover at the bottom, which is attracted by magnetic force and is easily disassembled. This is much more convenient than screws. Good design. The following buttons and jacks are similar to the A9. Let me introduce a bit: AUX input, network cable, USB, location selection, and power port. However, this usb is only used to debug and upgrade, as well as connecting iphone and other devices, not to insert U disk songs. Behind the handle groove. Danish design, Chinese OEM. Front logo LOGO and a sewing thread. A little look at the effect I am handcuffed again Don't handcuff to poke the horn. I finally managed to control my hand and quickly covered the lid. Psychology says that once you think you can't do anything, your body will not be able to do anything. Don't you think about a pink elephant. What's in your head? Of course it was a bunch of pink elephants. The voice should hear it. It involves a lot of people's subjective feelings, as well as your playing sound source, and the degree of your music. Can affect the sound of a speaker you feel good or bad. My concept of B&O products has never been down. Personally think that the wingman won't make the sound of the speaker better, and the wingman just makes your brain and speaker consistent, that is, picking your ears and brains. It is a matter of opinion on this issue. Perhaps the downtime of other brands is useful. This is not discussed. A6 supports Dlna and Airplay, which greatly increases the playability of the speakers. That is, you have set up Dlna playback, which can read songs from your LAN hard drive without relying on the Bluetooth output of your phone. Why do you want to go with your cell phone? Does not affect playback. This is to download a BeoPlay and BeoMusic app software. The specific tutorial is not written, and the participants are not difficult. The H3 ANC was bought because the H8 was listening on the bus. The H3 ANC is small and noise-reducing. So start playing to see. The difference between H3 and H3 ANC is the noise reduction component without such a round shape. On the left is the H3 ANC. Experience, its noise is not as good as the Shure Se535, the sound quality is not as good as the 535 resolution, bass slightly better. Moreover, with such a circular noise reduction component, it's really troublesome. It's better to use a soundproof earphone. This ear plug is rather tasteless. I estimate that B&O will not upgrade it anymore. Those who are interested in buying an H3 will do so much cheaper. The H5 is a Bluetooth headset, and the battery is hidden inside the earbud unit casing, so it does not have any kind of drag-and-drop battery box with other Bluetooth headsets. This is a benefit. And charging is using contact charging, and it can be charged on the bracket. Good high-tech feel. Bracket, headphone left and right card into it just fine, with its own magnetic, very good. When the two headphones are close together, they will automatically suck. At this time, you think that you have your headphones hanging around your neck, and the music stops automatically. B & O these small details of design can really touch people's hearts. Maybe you buy a product because of an intimate little detail. This headphone sports, listens while walking and cycling. Do not listen when riding, it is dangerous. Do not listen to running on the road, it is still very dangerous. Walking in the community can be used. However, the se535 is also suitable for walking, so the H5 is a little tasteless for me. It is a fresh play. I didn’t even stay in these two headphones. Form2 looks beautiful and is still so super-decade after decades. The sound quality personally feels normal and can't hold my head. A8 is a headset, the sound quality is really good, I have got used to in-ear headphones, and the ear hole is relatively small, with this really hurt. The main portable model, this time really portable, can be put into my trousers pocket, only a palm size. This is also the first time that the company has been purchased from the dealer's hands. black. The design is like an oval pebble, thrown in the river beach is estimated to not be found. Put a button on the whole body. Use the minimalist design concept to the extreme. The button is at the bottom, covered underneath the plastic with a bo logo on it, but it can't be found. The button is used to switch the machine on and off, and long press to enter the Bluetooth pairing, and then continue to long press to shut down. Swing left and right can switch songs, shake it up or down, or click on the surface twice to play or stop playing. Hey, I'm really convenient. Alarms and gestures can be set via the mobile app. This rope also seems to be leather, a small metal fastener above, very fine. From such a small size, the sound is quite good. It is now my portable speaker. Where do I go from home? There is music and speech listening. Really practical. to sum up: Sound quality: A6>A2>A1>P2 Portability: P2> A1> A2> A6 The better the sound, the more expensive it is. The louder the better, the better the sound is, the less portable it is. If someone tells you that his audio products are small, good and cheap, in all likelihood, you will be fooled. What song you listen to is more important than what song you use. The equipment is all for music. Find a suitable one for you. A2 and Xiaomi Fang box, flowing music is very pleasant. B&O's products are suitable for daily use by families. They don't need to know more about equipment and do not need much hands-on ability. When he is a musical instrument, it is not a HIFI product, nor is it to pile up data or pursue the ultimate sense of hearing. Beethoven, Mozart, Michael Jackson, Huang Jiaxuan, Teresa Teng, they did not die, but became music. The youngest man in my family likes to play the music the second time. At night we often come to a ghost-dove dance. That's right, he didn't even have time to wear pants.

One day, the dealer asked me: A6 is listed, or not?
Me: I'm crazy, 7888 playing a Bluetooth speaker.
Dealer: No, ah, brother, the price I gave you is XXXX.
Me: Then I need three first.
Dealer:....... 
I have to say something more. I can only say better than A2. From bass fist to meat ah, the dynamic range is also very large, it is suitable to listen to vocals, inappropriate to listen to symphony, large preparation. The Beoplay series of sounds has been tuned for home audio rather than HIFI audio. 
The official picture, the volume control through the hand touch and slide on it. It is very high-tech. My mother was shocked to see it.
