I have purchase this brand in the past and have be very happy with the sound and durability . I use these to listen to my mp3 player while work out and the fit be perfect . sadly , the connection from this pair to my player seem to create more static and the sound go in and out during listen . because they be so cheap , I do buy two pair and will switch to the other pair soon . hopefully , it be just a glitch in my current headphone and the other pair will function as other have in the past .
