Do anything, hear everything. Our in-ear headphones are built for active lives and measured by the same standards of audio excellence that have guided Bowers & Wilkins for 50 years. The headphones are smaller. The music isn't. A driver for highs and mids, with a separate driver for bass, creates full, forceful sound. This is Bowers & Wilkins Dual Driver technology. Go for eight hours battery life. The PI3 microphone carries it clearly on every call. Voices are heard with the same clarity as the music.
