These are very good headphones. If you don't need "basshead bass", just accurate , crisp bass , then these are for you. Although they are comfortable around the ears, they are very heavy, not too big of a deal imo, the quality of sound and overall design of the headphones makes it alright. Amp is not really required due to the low ohms on these too.   I opted to return them tho, as the bass was not powerful enough and they were too heavy. if they had basshead bass and werent so heavy, they would be perfect.
