The Sennheiser MX270 headphones are a great buy. They sound as good as most and look great. The L and R markings on the down shaft are easy to read so I always know I've got them in the right ear. My only complaint is the 90 degree bend of the plug which often gets caught on a pocket flap or something.
The MX 270 are powerful earbud headphones designed for dynamic stereo music reproduction on the go. They feature a high performance dynamic driver system that reproduces wide dynamics and full, rich sound quality without added bulk.
