Great WAVE quality playback.....impressive all around....purchased 3 units....hope they lastUpdate: Now purchased 4 units and giving as presents....Using Micro SD cards and WAVE files of excellent quality recordings, the sound quality is pretty outstanding overall and will not fatigue the listener after hours of playing. I play a wide variety of music from classical/pop/Jazz/opera and it all sounds natural. It cannot make a poorly mixed or recorded piece not sound garbled with some junk produced today. If you want an economically priced, fairly true reproduction of your WAVE quality recordings, this cannot be beat. Battery can probably be replaced after a few years by accessing screws under base pad.

The media could not be loaded.  1. It works fine with my smart phones (iPhone and Samsung), laptop computer and Echo Dot.2. Bluetooth connection is quick and smooth3. Loud enough for bedroom and living room.4. Sound is clear. I am surprised by the bas performance. I can feel and “see” the drum. It’s fund to watch two speaker surfaces vibrate with the music rhythms (see video).5. Long battery life. I have use 10+ hours without recharging it.6. Size fits well for indoors use. The enclosed bag is convenient for carrying the speaker around.7. It can be used as speakerphone in my office. When 4 people sit around my table, it works much better than the speakerphone function on my iPhone 7.

It was a good speaker for what you are paying but it didn't work out for what I needed. Some flaws you have to consider. A loud power off voice when turning off the speaker. What's up with that? It disturbs everyone in the room. You can't use it for a remote speaker to watch a movie because there is a sound delay and the voices don't match the lip movements. You'll have to have it wired up for that purpose.

I am really impressed with the sound of this speaker. It can be played quite loud and thy is easily heard from another room. The bass quality is very good as well. The speakers have a no slip pad on the bottom so there is no risk of them vibrating off the shelf Sound projects outward for each side providing decen stereo separation for a portable speaker. The battery holds its charge fos several days. This is a well made portable speaker, and I highly recommend it..

I know that I should have checked it out earlier, but it was bought as a backup to another speaker. I opened the box and plug it in and let it stay on the charger for 12 hours. Pressed the power button and nothing. It does not work. I now find that the support for it ran out in may.So I guess I will just have to take the loss. But never again will I purchase a product from this company.

We have been very impressed by the sound quality and loudness from this little unit. Easy to connect to too from a bluetooth device.

Battery life is quality, connects easily to multiple devices. However, leaves much to be desired if you want serious sound. Good for easy (solo) listening, tough for a backyard bbq. The product itself is not bad but perhaps my expectations were misguided. Ended up spending closer to $200 on a device that creates the sound I want.

I left this on charge for DAYS at a time. The red charge light always blinked and would never go off. When I took it off usb charging and used it as a Bluetooth speaker I could only get an hour out of the battery. And once the battery went dead, I could not plug into usb and use the speaker. It would say low battery and decrease the volume to the point where you could no longer hear it. I don't know if I got a defective unit or not. If not, this is a $50 paperweight. Returned to Amazon without issue. I am currently considering the AIWA EXOS - 9 as a replacement. A much higher priced speaker granted, but given this experience I don't believe I will ever be happy with a $50 Bluetooth speaker. The Aiwa is charged by an ac outlet and in addition you can run the speaker on battery or house current.
