Pros:-Everything sounds amazing-Blocks out most outside noise-Fantastic bass response-Long, durable cord-Comes with larger phono plug-Adjustable-Can be amplified quite a bit without adding distortion-Not $150+Cons:-After prolonged periods of listening, they really start to hurt the ears. It's like someone is tightening a clamp around my head.-Any music under the quality of a 256kbps 44.1kHz MP3 sounds degraded (but that's because it is). Time to upgrade your library to some higher quality MP3s, or better yet FLAC.Other Notes:-Despite the pain endured by listening to music with these, I still keep these on for much of the day. ERMERGERRRD, such sound quality.
