I have to say that I was really surprised with these headphones! I tested these against my $150 AirPods and I was shocked at how well these sounded compared to them! The fit is comfortable. They look and feel just a tad small on my ears, but that is probably because I'm not used to wearing an over the ear headphone. They connected quickly and easily to my iPhone! Very easy!. The controls all worked great! The hidden surprise was the built-in music player! You can insert a MicroSD card with some audio tracks on it and it will auto play the tracks! No need to be connected to ANYTHING. I did not know this was a feature when I purchased!
The only negative thing I could say: There was a little bit of "popping" that could be heard when using it on a phone call. The caller on the other end of the line is the one that was hearing the popping, so I would say there is some small issue with the microphone.
