The flagship model features NTT's proprietary dual-core technology which suppresses sound leakage ("PSZ"), and clear delivery of just your voice without the noise through Magic Focus Voice technology ("MFV"). Ultra-lightweight at approx.6.5oz (185g) with a distinctive futuristic design is certain to make a statement. Approx. 20hrs of playback time on a full recharge makes the nwm ONE ideal for a seamless all day use experience.
