Move over, Jawbone. Motorola’s impressive new Bluetooth headset, the Endeavor HX1, takes noise reduction to the next level.

The noise-destroying features in this headset are truly revolutionary. Motorola combines its CrystalTalk noise-cancellation technology with a new stealth mode that will allow you to talk (and actually be understood) in places where you can’t even hear yourself.

Most of the time, the headset will work fine in normal (CrystalTalk) mode. This handles everyday types of noise, using two external microphones. The sound quality is very good. Friends I called had no trouble understanding me. On the other end, it delivers plenty of volume on my HTC Fuze and fits well in the ear.

Then when things really gets noisy, push a button and switch to stealth mode and the magic begins.

There are differences in the way competing Jawbone headsets and the HX1 reduce noise. The part of the Jawbone that touches your face senses when you are talking and then turns an external microphone on and off. But the HX1 doesn’t fudge on bone-conduction technology.

In stealth mode, the HX1 turns off its two exterior microphones and uses only a sensor that touches the inside of your ear.

“This is true bone conduction, picking up through bone conduction and not through external microphone,” says Natanya Ray, Motorola’s director of category marketing.

For the technology, Motorola partnered with Invisio, which developed the bone-conduction method and uses it in headsets for special military forces all over the world.

Does it work? Motorola has tested the HX1 in wind speeds up to 40 miles an hour. But I wanted to see what it would do with a lot of noise, so I headed straight to the toolshed for a couple of tests.

Test 1: HX1 vs. leaf blower.  My blower is pretty loud, 70 db at full throttle. So, I cranked it up, called myself and left a voicemail. On the recording, in stealth mode, I could hear myself fine. I couldn’t hear the leaf blower—at all. The winner by a knockout: Motorola HX1.

Hmmmm, what do I have that’s louder than the leaf blower?

Test 2: HX1 vs. air compressor. I’ve got an air compressor that’s really loud. And with the sound bouncing off the walls in a semi-enclosed carport, I can barely hear myself talking. But the headset got rid of the noise. Completely. The winner and undisputed champion: the Motorola HX1.

The voice does sound slightly muffled in stealth mode. But remember, we’re talking about the difference between being heard and understood as compared to being completely drowned out by noise. So that’s an impressive performance by any measure.

If the HX1 can handle those kinds of noises, airport commotion or driving down the road with the windows down should be no problem.

There’s a lot more to like about the HX1. It fits solidly in my ear so I don’t worry that it might fall out. Unfortunately, I can’t say that about some other headsets I’ve owned.

There are four different eargels included. My advice is to try each one to see which fits and sounds the best.

Also included is a clip that goes behind the ear for a really secure fit. You may not need it, depending on the fit with the eargel.

I especially like the voice prompts and control buttons on the HX1. With some headsets, it gets confusing over which button to push or hold. The HX1 has an on-off switch; one button to answer, reject a call, hang up, put a call on hold, or use voice dialing; a rocker switch for volume control and to mute/unmute calls; and a separate button for entering stealth mode.

The voice prompts tell the battery level and when the headset is paired and connected with the phone. That’s a very nice feature that makes the headset easy to use. But if anyone finds them annoying, the voice prompts can be turned off.

Another interesting feature about this headset—it can be connected to two different phones at the same time. So if you have one phone for getting work e-mail and a second phone for personal calls, it’s easy to switch back and forth with the headset.

Battery life is rated at up to seven hours of talk time and up to 10 days of standby.

The price is on the higher end of the range for Bluetooth headsets. The HX1 retails for $129.99 and is currently available only at Sprint.

As for the price, I’ve spent more than that buying an array of other Bluetooth headsets that didn’t work as advertised and wound up gathering dust on a shelf. This one is a solid performer that won’t be tossed aside and forgotten.

I normally don’t gush over gear. But the Motorola Endeavor HX1 offers impressive performance, ease of use and extreme noise reduction when you need it.

After many unsuccessful attempts in the past, I’ve finally found a hands-free headset I can depend on. In the Bluetooth world, this headset is a game changer.
