Rated 5 out of 5 by from *Throws money at screen* best earphones ive ever used in my life. i have bought some pretty good headphones that don't compare to these. They have amazing frequency response and their phrase hear the truth is as accurate as it gets. I will definitely be buying from jbl again

Rated 1 out of 5 by from Unfortunately haven't lasted long I bought this pair of ear buds in May and at that time they worked perfectly but in the recent weeks the left ear bud has stopped working some of the time and the buttons too have only worked some of the time. A bit frustrating for the cost.

Rated 1 out of 5 by from Disappointed These headphones are not good. Very poor quality sound. My earbuds that came with my iPhone are way better. I thought for the price I was getting good quality sound but was very disappointed.
