How's the bass on this thing?
A shopper
on Jun 19, 2022
BEST ANSWER: Considering it's a small speaker, the bass is fairly good. Audio quality overall is pretty good for something this size. It goes loud (and thumpy) enough to be obnoxious, if you're out in public with it. Since audio quality is subjective; if you really want 'good' bass, you need something larger.

Not a problem.. Very powerful bass, and midrange. Used it yesterday in an open park pavilion for ~75 people - unit delivered ample clean sound.

It's pretty boomy. My only overall complaint with it is that the battery life is less than stellar.

Pretty good. Just have to leave space around the speaker because the bass comes out the back.

Can someone share their tips on how to get two of these Bluetooth speakers to pair? I tried the instructions in the manual with having them both unpaired from any device. No luck. I then tried someone's tip on having just one of the devices paired. Still no luck.
Any other advice on how to sync these will be greatly appreciated.

BEST ANSWER: The instructions in the manual and the telephone support provided no assistance. Through trial and error with both speakers "on" touch the end of one to the charging port end of the other. You should hear a tone to tell you they are linked. One speaker will become the control unit for off function. With each use you will hear the tones to indicate the speakers are linked.

I tried too. It doesn't work. I chatted with tech support. They said the solutioni is to have the phone connect to both speakers and play both via the phone. I tried everything to get the pair, to pair. No luck.

Can you connect more than two speakers?

How can you turn off the beeping while at low battery? When the speaker is at or below 30 percent it beeps every couple seconds making it practically unusable.
New User U
on Jan 14, 2023
BEST ANSWER: Mine does the same, but I think at 20%. Not only that it skips a huge range volume near the bottom and continually increases the volume. Also it cranks the volume to like 75% when you first turn it on. Not my favorite speaker. Won't be keeping this one.

Mine starts at 20%. But it only charges up to 60% no more. These have that bug. Good sound especially with 2 they connect. I just bought 2 more. That way they cover about 8-10 hours depending on volume level. Full blast 8 hours.

How turn off flashing blue light?
A shopper
on Jun 28, 2023
BEST ANSWER: It depends which reason the blue light is flashing. It will flash when you first turn it on because it is a bluetooth speaker which is always looking for a signal. The other time it will flash is when you have two speakers, and touch the right end of one to the left end of the other and the speakers will supposedly then pair up in stereo. One will flash and the other will go solid. But I haven't been able to achieve hearing a stereo signal from my iPhone because it uses bluetooth 5, but the speakers are designed for bluetooth 4.something. With my phone OFF, no bluetooth to look for, if I plug in a signal from a 3.5mm plug into the right side it will flash slow, but it seems to only stop flashing once it has found a bluetooth signal.

How do I get speakers into TWS mode? Manual is not helpful
A shopper
on May 7, 2022
BEST ANSWER: The manual appears to be incorrect. The manual states the speakers should be unpaired. After trying to touch every part of them together, I tried doing it with one of the speakers paired to something. That appeared to work, one of them played a tone, the unpaired speaker turned solid, and when I turned one off the other turned off.

When used as a pair in TWS mode how do you determine R and L channel???

Can L/R stereo be achieved with the wired aux line in or only with 2 units and the TWS Bluetooth configuration? I’d like to use the Aux Line In and hear stereo. Is it possible?

Well built (solid) but not very loud
This was to be used for increasing the sound of my TV set, but when I have it bluetoothed to the TV, the TV speakers shout down and only sound is thru this device. It is no boom box by any stretch, but still is a nice device for taking out into the garage or on a trip.

More than impressed!
This was a wonderful acoustic surprise! I've bought other bluetooth speakers, some smaller, some about this size and they did fine, but this one is exceptional. The bass is incredible, way more than I thought could ever come out of a speaker this size. The midrange and treble are delightfully clear. I'm glad I bought two at this fantastic price so I can leave one downstairs and leave one upstairs. Thanks for doing so well.

Its got some weird quirks
Starts beeping once a minute at 20%, turns up the volume on bluetooth to 75% when you first turn it on and blasts out your ears, misses a large range of volume near the bottom end, continually turns up the volume without your input.
Would not recommend.

Great Sound once setup
I agree with other reviews that it can be tricky to pair in surround. Bought two and one of them was bum and wouldnt charge past 60 percent and wouldnt pair either. MP replaced and new one is great. Two together is one of the cheapest best solutions ever. I used to always want to run wires for reliability, but for the price I forget that thought altogether. Plus I can take on road trips. You can't miss with these

Great Sound, poor documentation
These really fill our new outside space with sound and are easily portable to other locations.
Soundstage is great, bass is amazing when places on a heavy table and the overall performance is wonderful (to these old ears).
The documentation on the other hand appears to be written for a different set of speakers.
Linking the speakers to each other was not possible when following the printed instructions.
After three tries putting them "head-to-head" as specified, I was ready to return them as defective.
After a little thought, I put them "head-to-tail" and Shazam, they were linked.
Connecting to my phone was a snap and I'm using them daily.
