Summary: The new Sennheiser IE80 earphones are only a small upgrade over the equally competent IE8. Having said that, we can say it with complete confidence that these in-ear soldiers will appeal equally to the crowd that likes the 'neutral' sound, and to someone who wants more thump to the tunes. The trick is in the little screw dial that lets you tweak the sound to your liking. They might just dent your wallet though.
Pros: Extremely detailed sound reproduction, Powerful but taut bass, Consistent blocking out of ambient noise, Very comfortable to wear for long durations
