If you think you can't get great sound from lightweight player headphones, you haven't tried these. Open, on-ear cups provide big, natural sound, while a unique design lets them fold for storage in the included case.
"One of my all-time favorite headphones, the PX 100-IIi sounds terrific, and in this latest iteration sounds better than the Grado SR60—-my long-time favorite headphone in this category." — Tyll Hertsens http://www.innerfidelity.com/content/innerfidelitys-wall-fam…
Do these have an in-line microphone?
