Used for radio listening to an MP3 player: pleasant, intelligible words, balanced music with detailed highs and low enough. May not be appropriate for excessive bass lovers (although it's still trying ...). Did not notice vibration. Light to wear. Would have liked a small clip on the cable to secure it on a garment.
Satisfied with my purchase, for the record and for the price service. Purchased after visiting the site DigitalVersus.
