"Living up to the hype (so far)"4.5 starson by amateriat
Pros: Most secure fit of ANY BT headset I've used; Sound quality is solid using CrystalTalk mic, "good enough" in stealth mode; a *real* on/off switch; Send/end. stealth, volume buttons have "just right" sensitivity.
Cons: Getting the right fit can be somewhat fussy; not cheap. (But you get what you pay for.)
Summary: Like others, I've been champing at the bit for this to finally ship. I spend a lot of time getting around by bicycle, and my experience with previous BT headsets have been dismal. Very happy to say that the HX-1 seems to deliver on the bone-conduction hype. Yes, according to one person, I sounded a wee bit like Stephen Hawking, but every word was intelligible, which is the main point of stealth mode; it's not for crooners. It also means that I no longer have to hastily slow down and head for the curb every time I get an incoming call, which I reckon is where the greatest risk of an accident lies with Driving While Yakking. (I'm not much of a yakker: whether riding or walking, I tend to keep my conversations short, sweet, and to the point, preferring to save the long convos for face-to-face encounters.)
Aside from the Killer App of stealth mode, the headset is one of the more comfy-fitting sets I've used, and by far the most-secure: Bouncing around on uneven pavement doesn't seem to make the unit budge a millimeter. Fitting the unit to the ear *does* take some work, and it's easy to get the setup wrong (I gave myself an earache after about 45 minutes of wear, then found out I was using the left-ear "spring" for my *right* ear...like they say, RTFM). Once it's done right, I imagine most people will have a decent fit, but if you don't care for things protruding into you ear at all, you might not like this headset.
Controls are superb: The Send/End and stealth mode buttons, IMO, require just the right amount of finger pressure to actuate, not so much that you're pushing the headset into your ear (uncomfortable), nor so little that you risk accidentally actuating a function (annoying). The Volume rocker-button is quite intuitive in use, and that on/off switch...what else is there to say? Far better than some tiny push-and-hold-to-activate-or-deactivate number.
This may be one of the products where Moto has apparently gotten its mojo back. And not a moment too soon.
