5.0 out of 5 stars Best I Have Ever Used!, August 13, 2006

By	J. E. Nelson JB "Hypnotist" (North-East Tennessee) - See all my reviews (REAL NAME)

I can't say enough about this headset! Since I first purchased a BlueTooth cellphone I have been through 6 different headsets. For one reason or another each had either been returned within a week, or ended up in a drawer. This headset is just perfect. I can't think of a negative thing to say about it. It is the most comfortable, the battery life is good, the sound quality is the best I have had, and with all of the attachments Plantronics has added it gives this headset adaptability that I had never even thought of but really use! Of the 6 Bluetooth headsets I have owned the highest rating I could give any of them except this one would be 3 stars, but this one deserves 10!

As for the comments of others that the headset does not fit snuggly into the charger, it is NOT meant to! It is meant to slide into the charger so that it charges while just resting in the tube! This way you do not have to worry about whether it has made a good connection or not. If it is in the tube it is connected and charging. I would suggest caution if you place the pocket-clip charging tube a shirt pocket if you bend over a lot, but to remedy this just place it in your pants pocket instead. It vibrates if you get a call while in the charging tube, so you'll be alerted either way, and it goes in your ear so fast and comfortably this is not an issue when you are alerted to a call while it is in your pants pocket. IF the headset is in the charging tube you can be assured that it is charging, and don't have to worry about whether it has properly connected inside. Besides, how many other headsets are there that come with an accessory that lets you use a AAA battery to charge it in a charging tube while away from an electrical source? None that I am aware of. You don't even get this "option" with any other product.

5.0 out of 5 stars Setting the record straight, December 27, 2006

By	Mike B "Mike" (Jacksonville, FL USA) - See all my reviews

I like to read customer reviews online when considering purchases, but I rarely write any. In this case I feel that the record needs to be set straight because several of the reviews on this product are grossly inaccurate and may cause people not to buy a very good product.
My brother has one of these and he highly recommended it. He has had ZERO problems using it. I decided to buy one but wanted to check it out first so I read the reviews and was puzzled. I know how particular he is about gadgets. I decided the safe move was to buy this item at a brick & mortar store even though it would cost much more, based on the fact that some of the reviews indicated problems with the portable charging cradle and fit of the earpiece. I figured it would be easier to return locally if indeed that was the case. I can tell you from my experience that it is not. The earpiece fits securely into the charger and does not need to be scotch-taped or constantly held in place in any way. For the life of me I can't figure out how people are having that problem. I can only guess that they either didn't push it into the charger all the way or they have other issues. It takes no effort and it fits into the charger very well. The sound is very clear, and the ear gels seal your ear so the volume is actually very high and I had to turn mine down. I have asked people who I was talking to if they could tell I was on a headset, and they did not know. It is very lightweight and fits snug in your ear and is very comfortable. One big bonus that needs to be mentioned if that it fits so snugly that it doesn't need the ear loop, so if you wear glasses or sunglasses, this headset does not interfere with them like most of the other ones. It worked so well that I felt I had to do two things: write this review, and then buy another one from Amazon at a greatly reduced price, then take the other one back to the brick & mortar store & save myself the difference. If the reviews had been accurate I would have bought it from Amazon in the first place and saved a lot of trouble.

3.0 out of 5 stars expensive and marginal, January 5, 2007

By	David J. Gessel "davegessel" (Oakland, CA USA) - See all my reviews (REAL NAME)

It is a gorgeous design exercise, but not a great headset. This headset comes with a huge array of accessories in a nice presentation case. The sound quality is middle of the field and inferior to far less expensive headsets.

The headset is designed to hang in one's ear, which it may or may not depending on your head. If not, it comes with an uncomfortable wire loop that doesn't match the sleek appearance of the headset.

The charge it anywhere collection of adapters and the clever charging tube is impressive, but I'd rather have a decent battery and a standard USB Mini-B charging cable (why just about every headset has a connector that is -almost- a USB Mini-b cable but requires a special USB cable, as do most digital cameras, seems insanely stupid to me).

This is a stylish and compact headset, but the the compactness is somewhat compromised by the fragile in-ear silicone pad which doesn't last a few pocketings. The fountain-pen styled charging tube/carrying case is attractive and clever, but the silicone nobule pokes out on the same side as the pocket clip, pretty much insuring it's eventual dispersal during insertion or extraction from the tube.
