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

Putting on the headphones, you feel their softness to the head, but the sounds from the outside are heard, I press them with my hands to my head. Deep bass only when raised by the equalizer, then the headphones give out very low notes perfectly. Harsh mids, I cut around 3000-4000 Hz. High are good. The overall clarity and detail is excellent! As a result: I was not satisfied with the above uneven frequency response and noise from the outside. Because of them, I press them to my head. The gilding on the connector has worn off, but the sound has not changed!
