5.0 out of 5 stars Edges out the Jawbone, March 16, 2007

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.

4.0 out of 5 stars Good, but falls considerably short of great, March 8, 2007

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. If I have my phone in my shirt pocket and I hug someone, the connection is lost even though the two units are only about 10 inches or so apart. I can't say for sure if that's the fault of the headset or the phone (a Samsung A900M).

The unit is pretty light, and easy to wear. I wear it without the behind-the-ear piece, because I hate those (that was one of the main attractions to this unit for me; it doesn't require the use of one). It's very easy to put in, and once it's there it really does a great job of staying put, even without the behind-the-ear piece to secure it.

I have to admit after long periods of wearing it my ear does begin to get a bit bothered. I find myself switching it from one ear to the other several times throughout the day. Thankfully, that's very easy to do, and it doesn't bother me to do this. They include three sizes of ear piece with the headset, but having rather small-ish ears myself (or at least no larger than average), I find the unit cannot stay put unless I use the largest one. I have no idea who the medium and small ones are meant for. Children, maybe.

Battery life is outstanding. I wear the thing 4 - 8 hours per day (sometimes more), and I only need to charge it every week or two, depending on how much I actually talk on it.

The unit seems to be very solidly built. The manual is pretty clear and easy to follow, and the hands-free support the 665 has is very nice. I rarely need to touch my phone when I'm using the headset. Pairing it with my phone went flawlessly, but that isn't really a unique feature of this product these days.

I think Plantronics made an unfortunate decision when they elected not to include an AC charger with this unit, instead only providing a car charger and USB charger. That doesn't actually affect me since I bought it from a reseller who packages an AC charger with it, but it's something you should be aware of because yours probably won't come with one.

Overall I'm pretty happy with it. I use it a lot and I intend to keep it. If I were back in the market for a headset, though, I think I probably would look around a bit more at some other units. I don't know for sure if I'd buy this one again or not, but I'm not looking to get rid of it, either.

Update, March 23, 2009: I've been using the Aliph Jawbone I bought after this one a while back exclusively for a long time now. Over the weekend I managed to lose the earbud for it, so I'm using my 665 again until I can get another earbud for the Jawbone. As soon as I switched back to the 665 I started hearing "I can't hear you" and "What did you say?" and "You sound like you're far away" quite a lot. I had heard nothing of the sort when using my Jawbone for more than a year, ever.

I really want to like this Discovery. I love its styling (I think the Jawbone is ugly) and features. But sadly, at the end of the day these things are intended for talking on the phone, and if people can't hear me then all the styling and features in the world don't matter. I'm gonna get another earbud for my Jawbone (or maybe a whole new Jawbone if I'm feeling particularly saucy), and the 665 will be once again be relegated to a back-up role. It just doesn't do the job.

2.0 out of 5 stars Not good in the car, April 14, 2007

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.
