In my mind there are only 2 bluetooth headsets to consider right now, the Aliph Jawbone and the Plantronics 665. I owned the Jawbone and this headset. They both are fine in terms of noise cancellation and clarity. Miles ahead of the competition. I prefer the Plantronics in the end though. I can wear it all day and barely notice I'm wearing it. The Jawbone starts to hurt the back of my ear after an hour. 'Pocketability' is better with the Plantronics as well. I can keep it in my jean pocket and not worry about breaking it. I thought it looks better as well than the Jawbone. I also find if I keep the headset in my pocket and pull it out the Plantronics is easier to stick in / on my ear than the Jawbone. Upgrading from any other headset you won't be disappointed with either headset but the form, style and charging options made me stick with Plantronics over the Jawbone.

I gave up on cheap headsets and spent the money on this one as soon as it came on the market. Overall I like it. The AudioIQ works pretty well, but not quite as well as I would have hoped. I still get complaints of wind noise and background noise when I'm driving. Still, I can definitely tell a difference in the clarity of incoming audio. It's far easier for me to hear the other end of a conference call or other conversation than it was with other headsets, or even with just the handset by itself.

Additionally, I have had complaints on numerous occasions from the party I was speaking to that they could barely hear me - as if I'm calling from halfway around the planet - and I've had to switch from the headset to the handset. I personally find that to be pretty much unacceptable for a higher-end headset like this one. It not only happens, it happens often enough that I've taken notice, and I may have to seek tech support to see if maybe mine is defective.

The buttons are badly positioned and hard to press. Especially the main button; if I need to operate it (which I do in order to do just about anything) I find myself grabbing hold of the unit with my thumb and middle finger, and using my index finger to press it. Otherwise it feels like I'm trying to drive the thing into my brain because you have to push *really* hard in a direction that's almost straight in toward your ear canal. The volume buttons are almost as bad, and are equally poorly placed.

The Bluetooth connection to my phone seems weaker than it ought to be. It seems that if there isn't a direct line of sight between the headset and phone, or if you're more than just a few feet away, you'll get static in the audio.

I previously owned a Plantronics 645 which I liked quite well, but it came time for a replacement. I typically only use the headset in the car, so I was looking for one with good noise cancelling features. After using this headset for about 2 weeks, I received so many complaints from the people on the other end of the calls, that I had to stop using the headset and use my handset directly - just so they weren't completely annoyed.

I really like the fit, feel, and weight of the unit, and the incoming sound quality was always excellent. When I was stopped at a traffic light, outgoing sound was very clear and nice, but unfortunately even the slightest road noise was a big issue.

I really wanted to keep this headset because I still have some older accessories that are compatible, but unfortunately I will have to return it. With the DSP technology and Audio IQ I expected this headset to be better than my 645, while it ended up being much worse.

I had a difficult time finding a bluetooth headset that I really liked. I have spent a lot of time, and money, trying several styles. This is how I would rank the ones I own:

#1. Sound ID SM100 Ear Module Bluetooth Headset. Best ear fit, sound is sharp, clear & crisp. When not on the phone the headset changes to a listening mode and hearing through it is very easy. Overall my favorite.

#2. Plantronics Discovery(tm) 665 Bluetooth® Headset. This one also has very good sound but a bit muffled, not quite as crisp as the Sound ID but still very good. If you prefer a softer sound, not as sharp, this one would be best. It is also the lightest weight and fit was quite good.

#3. Aliph Jawbone Bluetooth Headset. I just couldn't take to this headset. I found it a bit awkward, the fit in my ear was just OK. The sound was tinny, kind of like listening through a tin can. I could hear but it was harsh sounding. This one did have the loudest volume.

I found myself mostly using the Sound ID, occasionally the Plantronics, and never the Aliph Jawbone.

VERY IMPORTANT: If you wear your headset a lot, and are looking for the ultimate in comfort, try a custom made earpiece from: [...] They have a kit that makes an impression of your ear and can make it fit just about all headsets. The ear piece that you get is feels like soft latex, actually feels like one of those gummy candies. The fit is perfect and the earpiece stays rock solid in your ear. It also blocks out all outside sounds. This is both good and bad I guess. If you use the Sound ID this is less of a problem as it allows sound to pass through it when you are not on the phone. A nice feature. The only downside I found is that these earpieces are a little bulky.
