Got this parcel in 12 days after order to zhytomyr (ukraine).
Tested bluetooth – it’s ok. Microphone mode can be connected from 2nd or 3rd time – you need set volume max and switch to ‘voice mode’. I recommend this item and seller.
Mic quality is middle – too thick wires, don’t break that.
Color: Black
M***s –
small but very powerful, it is for small spaces

I’ve already used it and frankly it’s good, for how small it is it has quite a bit of power. I use it to give classes in a hall with a lot of ambient noise and it’s fine. I highly recommend it, the only thing is that for using it outside I’m not sure if the power would be sufficient.

Excellent item for the girl to enjoy. Good audio and volume ratio, perfect for dressing up as Zoey from K-Pop and singing.

Excellent product for the price. The sound quality is excellent. I use it in a children’s park where there are a lot of people, and my group can hear me very well.
It is easy to use and charges very well.

I am satisfied.
Initially, I thought I had spent money for nothing. When I went to teach my classes with her, I found that the sound is reasonable.
It has a very compact size and the battery lasts a long time.
The Type-C input on the charger is also a very good feature.
