Active Noise Cancelling A miniature microphone in each earbud listens for noise (engines, chatter). The Noise Cancelling circuitry then sends the reverse audio signal to your ear to effectively cancel out the external noise. Remote Runs on 1 AAA battery for up to 50 hours. A convenient sound monitor button allows you to quickly listen to external sounds, eg. public announcements. A through feature allows the earphones to continue working even if the battery runs out and cannot power the noise cancelling circuitry. Dual Chamber Mechanism An acoustic precision designed 2 air chambers system greatly amplifies bass. With clear medium and high frequency reproduction, the overall expression is deep and rich. 2 Earbuds Positions The earbuds can be adjusted in 2 positions to give you a personalised fit to achieve greater sound isolation and a better acoustic room in your ear. Reducing sound leakage enhances the bass performance. Elastomer cord The cord is wrapped in elastomer, a highly elastic material that is tough for everyday use. Epi-Leather Pouch Square shape with a magnet button makes storing very easy.
