I bought a pair for my sister for Christmas 2018 she is in love with them. I tried them out thinking that it was going to sound "OK" but let me tell you, I was wrong. The sound quality and bass is amazing. They sit in your ear very comfortably, I don't even feel them. Some other make my ear hurt but not these. I convinced myself to get myself a pair now. I would recommend these earphones and I already have to friend.

Speaker and microphone is not working properly , and some time not connect it.

I've been using them regularly for over 3 months; 2-5 times a week for 30 - 90 minutes at a time; call quality and mic reception is very good, I use them for biking a bunch, they're comfy to listen to stuff while in bed. I had to hunt down 'wired bluetooth' headphones that didn't seal or sound dampen and these pretty much nail it - great deal for the money.
