Very neat and light, over-ear - which takes getting used to when you've got Bose QC15's, but reasonable quality sound, slightly bass-light, but super convenient as Bluetooth driven from your iPhone (other smart phones are apparently available!). Best feature is the small size to which they fold, very convenient for stuffing into back-pack or man-bag...
