Review on Sony WI C310 Wireless Ear Headphones by Chong Won ᠌

Build quality, weight distribution - approx. The ear pads did not fit me, but I replaced them with something from the stock and the issue was resolved. The sound is normal for earbuds. Did not like the high frequencies, but tolerable. The battery life is 5+ for this type of headphones. BUT! They keep losing connection! Tested with phone (xiaomi, all background apps closed), laptop, ipod nano. It is stated that they catch bluetooth at a distance of up to 11m. It wasn't even close. The sound cuts out from time to time even if the phone is in front of me on the table. And if you walk and the phone is in your pocket - everything is really bad. The JBL wireless speaker at the same distance does not break the connection (all devices are the same). Perhaps there was a marriage. I managed to pass. Check carefully when buying :/
