The dynamic range may be a little too good. I like to listen to music before I go to bed and I would use the Samsung earphones that came with my player, and by the way they are very good for being the included earphones. Since it's right before bedtime, I'll turn my player's volume down to 2 or 3 (out of 30). The J2s when turned down that low on volume, the higher frequencies I can't hear like I could with the "cheap" earphones. Perhaps it's my hearing. This really isn't a complaint because when I turn the volume up to say 10, It (J2s) sounds fantastic.READ MORE
