Ok for the price

I bought them to watch TV at night using BT. It was rather ok for that purpose. The main issue - they have broken after like few month of usage. Charging socket just got separated out of main plate. I'd advice to buy similar headphones with wireless charging type.

You get what you pay for

I use HDB-311 to listen music from my cell. Somethimes they have short drops in signal. OK, I suppose some more expensive headphones do not have that problem. All in all product is ok. Just ok.
