Review: Wasn’t expecting this to impress me. - This actually ended up being more impressive than I expected. It can connect to multiple devices at once however u can only hear one device at a time but its still super convenient. The sound quality is also really unexpectedly good, i was so pleasantly surprised with how good the music sounded, and i have not used it long enough to say about the battery but so far it has been alright. I have no complains about it at all, only that i wish i has gotten it sooner cause i would have benefited from it so much.
Review: 4 weeks of and the battery will no longer charge - Worked well while it lasted but now the battery will no longer charge. You can plug it in, red light comes up indicating it's charging then goes off. If you leave it on when you go to use it it'll report 20% battery and then die within 3 minutes.

### ⭐ 4 weeks of and the battery will no longer charge
*by G***A on 28 March 2024*

Worked well while it lasted but now the battery will no longer charge. You can plug it in, red light comes up indicating it's charging then goes off. If you leave it on when you go to use it it'll report 20% battery and then die within 3 minutes.

### ⭐⭐⭐ Decent for the price with only one slight drawback..
*by M***N on 22 November 2020*

Very easy to set up, audio is pretty good the only thing I'd say could improve is the battery life, seem to get 5 hours use before having to charge. Apart from that I would recommend it.
