Review on Bundle: Sony MDR7506 Closed Ear Headphones with Knox Gear Compact 4-Channel Stereo Headphone Amplifier - Professional, Folding Design (2 Items) by Ojasvi Sharma (Ojo) ᠌

I use with Cowon iaudio D2+ (Rockbox firmware), mostly Lossless, - FLAC and APE. I have never heard a better sound than this pair from a portable . Before that, I used Technics RP-DJ1210 . Heaven and earth, - the technician does not have such a soft bass, - I gave it to good hands . I do not advise the owners of phones - Apples, Samsungs and hts, as well as low-power players, to worry, they will not shake them to the fullest . Made in Thailand I am satisfied with the purchase.
