Excerpt: The Air-First headphones sound quality is as good as other units costing much more ( compared it with a competitor'so a friend of mine had ). They sync up easily with my cellphone. I make calls and can hear clearly the caller. The caller also can hear me clearly as well.
Excerpt: I wanted something to use while walking on my home treadmill. I was using corded headphones and the cord was always getting in the way. I mainly use the headphones while watching Youtube videos or movies on my tablet.
Summary: Every thing is great about it price ,weight . Sound ..they work from a long distance ...the only thing i didnt like is that every body around you can hear what you are listening to ..but i would buy it again and i recommend it !
