Radio Silenz is the world"s first active noise canceling headphone to employ wood housings instead of plastic. The real solid wood ear cups, coupled with the high performance 40mm drivers, provide excellent sound quality and low resonance, while remaining lightweight and comfortable to wear. The closed back, on-ear design also rotates 90 degrees and upward for compact, easy transport in the included travel pouch.Operating on a single AAA battery (included), Radio Silenz can be used with the noise cancellation on or off, or even without a battery. The unique Defeat button temporarily switches off the noise cancelation and fades down the audio, allowing conversation or announcements to be heard without having to remove the headphones, or having to repeatedly switch the noise cancelation off and on again.With today"s myriad of headphone choices, only Radio Silenz maximizes your listening experience by combining the acoustic advantages of natural wood with the technology of active noise cancellation.Real wood housings provide a more natural soundReduces outside ambient noise by up to 85%Can be used with noise cancelation on or offUp to 50 hours of operation on a single AAA battery (included)Lightweight, comfortable fitPadded ear cups rotate 90 degrees and upward for easy packingTravel pouch includedDefeat button temporarily overrides noise cancelation and audioCompact Control unit includes pocket clipGold-plated 3.5mm right angle stereo plugAirline adapter includedInside the box:Radio SilenzTM Active Noise Canceling HeadphonesAirline AdapterTravel PouchAAA Battery
