Some of my favorite headphones.

 Shure has done a outstanding job of blending terrific performance with reasonable cost in the SRH440 model. Amongst the best-sounding sealed headphones under $100, the SRH440 features
Terrific build quality + ergonomics = very high quality sound. It comes with a 2-year warranty and a 
detachable coiled cable. A folding collapsible headband makes it good to go on the road.
The SRH440 headphones have a mid-sized circumaural construction with full-size sealed earcups designed to deliver excellent isolation in mobile listening or recording studio use. The proprietary Shure-engineered 40mm drivers deliver focused audio reproduction across the entire frequency range with a clean, articulate, and well-balanced musical presentation that neither leans too far forward nor is overly warm
