Great, But

Rating: 4

I love this product because it is comfortable, unobtrusive and lightweight but the earpiece does not seat well in the charger which means it frequently fails to charge. It falls out or pops out of charger. They cheerfully sent me a new one. But same problem. I hear very well but get some complaints from people receiving my calls.

buyers with problems using RAZR, please read

The only reason I've decided to write a review here is to let the buyers with problems using the RAZR's mini-USB connector.
There are 4 adapters included in the package - Nokia, Motorola, Palm/Treo and Mini-USB.
Check the bottom of the retail box and make sure "Mini USB" is included.
If it does, it should work perfectly with the RAZR charger.
However, the mini-USB adapter looks a little different than the conventional one - it almost makes you think that the mini-USB connector won't fit.
But go ahead and plug the connector into the adapter...you'll see it fits perfectly.
I'm not sure why they made it in such odd shape, but it works.

By the way, some buyers have complained that the headset unit doesn't fit well into the carrying pocket and that it doesn't stay securely.
There is a charging connector inside the carrying pocket and the headset unit needs to be firmly but gently pushed in.
If you just drop the headset unit into the carrying pocket, it won't stay in.
So do yourselves a favor and give this a try - push in the headset unit firmly but gently. This should help.

I gave this product 4 stars.
As some reviewers mentioned, it's not perfect.
However, I don't think there is one that's perfect so this isn't a problem to me.
This product does what it's supposed to do very well.
The most important requirement for a headset to have is a good sound quality and the Discovery 640 has it.
I'm actually very impressed with it - I'm able to hear the other end loud and clear, and the other end confirms they can hear me loud and clear. Most of them didn't even know I was using a headset.
And it's so compact and light.
Plantronics could have made it a little better in the usability department, but that would raise the price.
So overall, I'm very pleased with the product and would recommend it to everyone.

Performance good, but uncomfortable

I used the Plantronics Discovery 640 Bluetooth Cell Phone Headset for a little over a week. It functioned well, the AAA battery charger and multiple charging adapter worked as advertised. I found after wearing the headset for about 30 min my ear would become sore. I tried both the small and medium ear inserts in both ears to no avail. I also own a Motorola HS820 which I find more comfortable. I do wear glasses. The HS820 also operates further from the cell phone. The 640 has a limited range from the phone. I have returned the 640.
