Customers have mixed opinions about the sound quality of the headphones. Some mention that the sound is heard very clearly, and the microphone is very sensitive. They also say that it's good if you have a hearing problem, and that it puts the volume in your ear without going deep into it. However, others say that the volume level is not the greatest, the mic is so sensitive it picks up a lot of external noise, and it'll pick up wind noise.

2.0 out of 5 stars not good as it should be
Reviewed in the United States on July 14, 2009

Ive had four bluetooth earpieces and This one fits very comfortable and is the the loudest one Ive used yet. Its good if you have a hearing problem. I drive alot and have alot of road noise. The only problem is your voice is not clear for the other person your talking to. It is distorted and people will ask you several times what you said. The best one Ive used yet is the plantronics 925 even though I'm not 100% satisfied about the way it fits in my ear it is very tolerable and It cancels background noise out very well. I like it alot better than the jawbone. The jawbone is huge and I cant turn the volume up loud enough to hear because it dont go far enough in my ear.

I've always known Plantronics to sell very good quality products.
This is the worst Bluetooth experiments ever. Please stick with the pricier models . I believe its in the design of the charging unit.
It has now decided to just not charge anymore.
The light goes out, as though it is charged. But just as soon as you put it on. It cuts you right back off.
Waist of money for sure.

3.0 out of 5 stars Fairly Reliable With Few Flaws
Reviewed in the United States on October 6, 2008

This plantronics 640E model is sleek, easy to use and operate, and the first bluetooth without having to use the bulky ear hook that most bluetooths still require. It's pretty clear for the most part, but there're times when static starts creeping up when I was talking, and it's pretty annoying. The pairing with the cell phone will at times get interrupted in the middle of a conversation, which was a real hassle, and the connection of the headset will get short circuited from time to time that you can't establish any connection, even though the pairing of the cell phone is working properly in the meantime. Overall, it's a decent headset for the price, along with a sleek pen like charging unit which is really convenient.

4.0 out of 5 stars Works decently with a few quirks
Reviewed in the United States on December 11, 2008
Verified Purchase
Overall, the headset works well. Sound is good, it charges pretty quickly, and having the portable charger is nice. A couple quirks keep it from 5 stars though.

First, I don't like headsets that don't have an ear loop - they just don't stay in my ear. So I use the optional ear loop with this, but it's not the most comfortable thing - it's basically a thin band of hard, springy plastic. It does the job, but it really seems like an afterthought in the design.

Second, at times it seems to turn itself off, and not just because the battery loses its power. When you put it in the charger, that seems to turn it off for one, which is weird in itself. But it also just seems to turn off if unused for an amount of time (like a couple of days). Not necessarily a bad thing, but I don't remember reading about it in the manual.

2.0 out of 5 stars Handsfree
Reviewed in the United States on March 5, 2012
Verified Purchase
I am not satisfied with this product because the loop attachment for the ear is extremely flimsy and the ear plugs are very fragile to insert. I broke the first plug setting bluetooth up. It is not well put together and feels like it will fall apart in my ear. Other than that, it works well, holds the charge and turns on and off easily.

1.0 out of 5 stars Don't buy it
Reviewed in the United States on June 25, 2009

I am always looking for new bluetooth headsets and I saw this one and liked it. I bought it and when I got it out of teh box it was almost what I expected, but then ... why do you have to have an extra device to charge it? why doesn't it charge directly like others?
And then it is such a hassle because it won't stick to the charger long enough to charge!!! a couple of minutes later it just turns off and you have to giggle it to start charging again.
I do not recommend this specific item to anyone.

5.0 out of 5 stars You'll hardly notice it's there
Reviewed in the United States on May 31, 2008
Verified Purchase
Featherweight! Unobtrusive, great sound both incoming and outbound. The silicon conductor which sits in the ear comes in three sizes for optimum fit, and the earwire which fits over the ear is much more tolerable than others I have tried. Volume control is simple to use and not positioned in a place where it can be hit accidentally. The power button is on top of the unit and requires a positive push to power on, actuate voice commands or turn off - smart design!

The only possible detracting point is its susceptibility to wind noise, but I have used it while walking more than most might, I expect.

Unfortunately, this unit ceased charging after about a week of use, but as always, Amazon shines and is sending out a replacement, which I anticipate will give me years of use.
