A borderline small to large speaker for the bag. The battery seems to last a long time. To select the radio, we connect the USB and hold down play until the station search is complete. After the search is finished, by holding down + or - we select the saved stations. The volume is very good for its size. The bass is low. The only negative is the lack of a hole to attach a strap.
I don't know if you can pair it with the same speaker for stereo. On iPhone 2022 it connects in the first 4-5 seconds.
The on/off is with a switch and it doesn't turn off by itself

Very good for its size and price. Good sound performance, difficult to operate (especially the radio), very good reception of radio stations. I consider it a very good choice.

AMAZING!
Words are unnecessary.
If you take care of it from bumps and such, it has a very strong and clear sound, disproportionate to its size.
Good battery life.

I am extremely satisfied with its performance. For the money, it easily outperforms the equivalent from Sony. The addition of the radio is very good. At very high volume, it distorts slightly. For use on a small balcony or at the beach, camping, etc., it is just right. VFM

update: after some time of not being used, it no longer connects to any Android device, PC, or iPhone. The radio works normally, however. It doesn't even show up as an active/available Bluetooth device, so it’s going to recycling...

One of the best purchases I have made!! You forget to charge it..... The radio works with the charging cable (not with the jack), the Bluetooth finds the device quite quickly, just make sure there are not too many walls in between because it interrupts the signal. The memory card works perfectly! Also, after a little practice, it becomes a piece of cake to use! If it was waterproof, it would be the perfect choice for everywhere....

Excellent radio performance, flawless connection with mobile and laptop. Endless battery life. I haven't inserted an SD card yet. Very good price. I think it's the best I could get for this money

The design is top-notch, the battery lasts for a day and a half, the sound is excellent, powerful, crystal clear! I have three of these speakers.
There are only two things I don't like:
1. The radio has an antenna that connects via USB, which makes it very susceptible to interference! Even 5 euro Chinese radios have a built-in antenna. (if you're asking me, I don't use it for the radio)
2. The media player doesn't recognize folders on the memory card (I wish it did)! This can be overcome by using a Bluetooth MP3 player or a mobile phone!
I really like it.. I recommend it.. you won't regret it.

I bought it here about 6 months ago after seeing it from a friend of mine, so I knew what to expect... I am very satisfied with its value for money and I believe it is worth even more! Good construction, clear sound, and quite powerful for its features, meaning that in a closed space of 10 x 5, you can comfortably use it as a home music player (not for parties, although I have used it in a gathering of 10 people outdoors and we used it for music response with very satisfactory results)! It is small in size, so you can take it with you wherever you want! I gave it four stars because the radio is not worth it... Unfortunately, it is difficult to catch a signal! I use it mostly with Bluetooth because I haven't managed to create a playlist on a memory card.... As for the battery, you truly forget that it works with a battery!!! That's all from me, I highly recommend it for its price!

I have it for a week and it really impresses me because it is small but more powerful in sound than it seems!!! It connects easily with bluetooth, but I mainly use it with a micro SD card!!!
It's worth the money, although with the radio due to the lack of a screen it's difficult but its reception is not.. (I tried it in various areas of the city), I don't care anyway, so everything is fine!!
I recommend it regardless, due to its small size and weight!!!

10 days later, finally the radio has excellent reception, my mistake, it needs to scan on its own first and then you choose the frequencies it has saved on its own!!!
The battery lasts and lasts, the volume is very good and I work in a noisy environment!!
Excellent again!!

The impressions of the first day are not related to reliability (time will tell), but to sound quality. Undoubtedly, clear sound throughout the spectrum and good bass for its small size. Although round, it fits in your pocket. Surprising sound for such a size. Value for money 5. All Anker bluetooth speakers deserve special attention.

I have been the owner of this for 1 month now, I can say that it is one of the best Bluetooth speakers I have had so far (I still have 5 more). Starting with the battery, it is very powerful and lasts around 10-13 hours. The sound and bass are very strong, the Bluetooth frequency is one of the best, you can move around the house without losing the signal, it synchronizes immediately with your mobile phone. The downside is that it cannot sync with 2 mobile phones, you have to pair it again from the beginning if you receive a call on one and open the other. It has a radio (to play the radio, you need to connect the charging cable and not the jack cable), it plays with a microSD card, and it also has a jack to connect it. It also has a microphone for answering calls, but you have to hold it close to your mouth for the other person to hear you. If you find it at a better price, it would be a good deal.
