The ANC300TW will deliver a premium listening experience whenever or wherever. With its 5.8mm DLC (diamond-like carbon) coated driver accurate audio is delivered offering a true reproduction of original recordings. To realise better audio the active noise-cancelling microphone has been placed on the sound conduit so as not to disturb the audio delivery to your ears. While maintaining noise-cancelling performance with this structure high-frequency components are transmitted without loss. The sound quality and noise-cancelling effect are maximized.
