Online Only! For a limited time, get the Motorola Endeavor HX1 Bluetooth Headset for only $110.49.

Talk hands free where you never have before on the Motorola Endeavor HX1 headset, thanks to Motorola’s revolutionary Crystal Talk™ technology with a stealth mode, delivering an unmatched headset audio performance even in the fiercest conditions. First of all, reduce everyday background noise with the default Crystal Talk mode which utilizes dual microphone noise cancellation technology. Then, if background noise and wind reach extreme levels, switch on stealth mode to activate true bone conduction and seal off all background noise from your conversation so you know you’re being heard. As you speak, the stealth mode sensor captures your vocal vibrations and seamlessly converts them to speech so the listener hears your voice only.

Motorola Endeavor’s Crystal Talk™ technology using dual microphones provides best in class audio experience in typical noise situations.

Motorola Endeavor’s TRUE Bone Conduction technology has no traditional microphones; it uses an in-ear sensor to truly pick up the vibrations of your voice. When you speak, your voice will vibrate through your facial structure and up to your ear. This is detected by the stealth mode sensor on the headset resting in your ear. The in-ear sensor does not pick up your surrounding environment (wind, noise, etc), thus allowing you to carry on the conversation anywhere.

I love their jabs at Jawbone. I've got the HX1 here, and it really is an amazing headset. The jawbone conduction is amazing - but you really only need it in the absolute worst of conditions. A noisy fan or car won't make it worthwhile. Standing next to an express train will.

Oh, and it has a sliding on/off switch, which is a hell of a lot easier than holding a button down. Voice prompts are nice and clear,and the volume is great. Well worth the price.
