Review on AIYIBEN Mini Bluetooth Earbud - Smallest Wireless Invisible Headphone with up to 4-5 Hours of Playtime, Headset with Mic for iPhone & Android (Skin) by Que Wade

These are good little headphones for the money! I haven't tried using it for phone calls but it gave me about 6 hours of music. The sound quality was to be expected for the price. not loud but loud enough that I can hear my music in a noisy factory. The only two issues with this product, it's quite uncomfortable and keeps slipping out of my ear, which brings me to the second point and also why I gave this headphone 4/5 stars. it broke when it fell out of my ear. It might just be because I was on hard concrete, so maybe nobody else will have this problem, but it's something to keep in mind.
