## Questions & Answers

**Q: Is there a way to disable welcome and goodbye sounds everytime the device connects/disconnect?**
A: It's pretty annoying and that sound is too loud makes it impossible to use in the office, maybe I have to return mine.

**Q: Is the mic any good for calling ?**
A: So I've found hacks for these speakers, put the microphone closer but not be able to blow air in the microphone hole, and also I put one side of the speaker up either by hand or shoulder when I really need to pay attention to what I'm trying to hear, very clear, clean sound music and talk, long battery, have a good one

**Q: Can you wear this while sleeping?**
A: I wear it around the front of my neck as I sleep mostly on my back. It is perfect. I can even roll onto my side with no problem.

**Q: When you turn it on or off etc, is there a voice yelling at you like it does in many other Chinese speakers? If so, can you turn it off?**
A: It does let you know you are connected or it says goodbye when turning off not yelling at all these are nice wearable speakers

### ⭐⭐⭐ Review
*by D***I on 19 January 2023*

Inget för musik, stereo ljudet svajar, irriterande. Startar inte diskret utan altid med med halva ljudstyrka och det går inte justera ljudet i förväg. Till ljudböcker och podcast fungerar någorlunda bra.
