## Questions & Answers

**Q: Why is you tube sound not playing through the speaker?**
A: What phone are you using. Mine works fine. I’m just having quality control issues with mine. The fabric is fraying. I’m going to exchange it for another one.

**Q: I just received mine, has anyone experienced any clipping sound issues ?**
A: I have two bought at different times and have not had any issues at all. Is the clipping all the time or only when playing loud? Try a different device and different source for your music. I have been using Tidal without any issues and the high res files sound great.

**Q: First time using my speaker. I turn it on and it turns right off. I cant find any answers in the manual. Any ideas?**
A: Did you charge it before using. The Directions tell you to do so. you will see four lights together when fully charged, If It doesn't change send it back

**Q: How is this compared to Ultimate Ears WonderBoom 3 WRT balanced neutral sound quality?**
A: I don't know about your speakers, but the sound quality is A1. I have a flat speakers to go in my studio and they are flat. The frequency is on paper. However the bass is not very good. They lack bass.

## Customer Reviews

### ⭐⭐⭐ Not great
*by  on Reviewed in Belgium 27 February 2025*

Latency when watching video is too high, even with the video mode enabled.Sound is ok but not great. Low on bass and general crispness of the sound.Volume controls directly control your devices audio, which i dont like because i cant control the sound volume as finely as id like.Ok build quality, ok price.Got this one because reviews where good.I do not agree and will not get a second unit as planned to try the stereo function.

### ⭐⭐⭐⭐⭐ Must buy
*by  on Reviewed in Spain 15 March 2026*

Great sound@great price!

### ⭐⭐⭐⭐⭐ Buy it. You'll be happy.
*by  on Reviewed in Australia 10 March 2026*

Excellent speaker and for the price, you won't be disappointed in the slightest. The equaliser takes a little playing around with, to get the best solution for your own ear preferences and the specific situation/room/ambience you are using the speaker in. I have had it for about 1 week. It seems to hold all frequencies of sound and clarity of music/vocals extremely well over any volume from low to max. I have a few other speakers and I feel this trumps the other ones for all-round quality of sound and is much more attractively priced. Good bang for your buck. I like it that much, that I am going to buy a second one so that I can pair them. It doesn't have a powerbank (no biggy), but it has a built in mic which is amazingly helpful for taking calls handsfree and the other person can hear you very clearly. Can't comment on durability yet as I haven't dropped it, or had it playing outside in the heat for any length of time. However, it looks and feels like it is solidly and professionally constructed. You can hold it in your hand easily, it's not too heavy. However, it could do with a wriststrap just for added convenience. I prefer it in all respects (price, quality of sound, loudness, features) over my comparable market bracket JBL Flip 2 and JBL Charge 6 speakers.
