The RP-HT21 On-Ear Lightweight Headphones offer full-bodied sound and comfort. A wide, ergonomic headband and foam-cushioned earpads feel secure yet never intrusive, providing hours of listening comfort. Large, 30mm magnetic neodymium drivers deliver clear, natural-sounding mids and highs while the XBS (Extra Bass System) port increases low-frequency response to bring alive music and movies.
