Very comfortable. -The sound quality isnt complete garbage, but its not good either. The glasses I received from this purchase on Amazon were not exactly like the store ones. They do not distort the sound like head mics do, so you get to hear the sweet natural tones of the kids voices. It did not sound bad, but clearly inferior to BT which is odd. The call will transfer to my phone, and then about 15 seconds later the headset will reconnect and transfer back. Tipps:Beim Anschluss über die Soundkarte an die Xbox One ist es wichtig das kürzere Konsolenkabel zu verwenden, sonst gehen Informationen vom Sound verloren. And then there is me with these tiny earbuds accomplishing the very same thing or better. the only issue I encounter was (you cannot wear a regular bra with it just because, it will show on the side if you lift your arms up) I used a pasty bra and it worked great and you couldnt see it at all. & plus theyre 10s!
