My english is ****, but I'll do my best. I tend to use headphones a few hours a day for listening to music while studying and comfort has lately become a necessity. My unit requires: 1 Closed back (library use), 2 Velour pads (to keep my ears from burning) 3 Confortable for prolonged use. *I'm not picky about the sound. The music is just there to repress my suicidal thoughts. Price range: around $150 Candidates so far: - Sennheiser 439 - AKG K272 - Beyerdynamic DT 770 PRO - Shure srh840 (with srh940 pads) - Beyerdynamic DT 250 So which one is more comfy? Suggestions of other models are deeply welcome.
