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

On my copy, the left trim tab on the shackle does not click and both move out 1-2 positions with prolonged (> 2-3 hours) continuous use. Its pros: The sound quality is excellent, especially for the price. They sit well, no discomfort even after 5 hours. Conveniently fold up. Got cons: I expected more from the build quality. Already on the third day (about 20 hours of use), the connections of the cups with the bow were slightly loosened.
