"Very good overall, takes some getting used to...."
Pros: size and charging options
Cons: charger / cradle has poor design, somewhat short battery life
Summary: Overall this is a great bluetooth unit. I bought it ($80 online) because it does not look like some huge monstrosity on the side of your head/ear. It's very small and light and at times, I forget I have it on. The earpiece design (in the ear) may bother some but I think that is one of the positive aspects. The user can hear very well with volume room to spare. Most I call do not know I am using a BT earpiece. I use it mainly in my auto and I have also walked with my 100 lb. labrador with the earpiece easily secure and have had no problem trotting along as he walks me. If you are into lots of movement outside or inside, this may not be the best unit for you. I think the ear support works well but I have only tried it on for size/comfort testing.
Battery life is OK. I can use it in my auto as I travel around the mile high city for two full work days without recharging. Depends on use obviously...I use it about 2 hrs per day or less. I have read that the 640 without the Digital Sound Processing has a better batter life. The DSP eats up more battery life but it is a fair trade off for the quality that I have experienced. I always can charge it during meetings using the AAA battery charger, a great addition when one is away from an outlet. NO other company offers OR includes it with the unit! A nice touch. If you want something that has amazing battery life, you may want to look elsewhere. Sound quality is quite good on both ends of the call. Most people do not know I am using a BT headset unless there is lots of background/wind/ambient noice. If I need my phone in a situation like that, I would just use my phone directly or call them back when in a different environment. Any BT headset or corded headset would pick up the ambient/backgound noise in these cases. No big deal.
Size is amazing and after using the 645 for the first two weeks, the unit seems durable. I have had it knocked out of my hands by a running 5 year old and it seems solid. It has a lot of technology crammed into a small package so it wont suvive being crunched if one sits on or the earpiece is repeatedly dropped. I pair it with the LG VX8300 and the connection is right on, no matter which system has the bluetooth turned on first. Initial pairing is simple. Since the earpiece has one function button it does take some getting used to. The volume rocker is easy and effective. I have found that if I hold the main button about three seconds and release after the first beep, it powers right up. I initially held the button as the manual stated and it always ended up too long and put the earpiece into discovery mode. I never accidently put it in this mode after the second day of use. It also will take some time to 'hear' when the device connects to answer or connects with the voice command. The voice command function needs to work in a very quiet environment (ie windows up, music/background noice real low) or with you phone set on LOW sensitivity. The three sizes of earpieces are grippy for your ear and Plantronics sent me another set after the aforementioned pooch decided to chew on the size I use-go figure! Great support Plantronics!
Overall a great unit with one gripe: Plantronics did NOTHING to address the fact that the 640 AND 645 earpiece unit sits very loosely and has the potential to fall out of the charger piece. Since I dont place the unit in my shirt pocket to carry or use the pocket charger, it's not really a huge deal. But for charging on my desk it seems ok - if the charger topples over, it will not have the contact to charge. One just has to be careful, I guess. The aluminum carry case is nice but I fit all I need into my oakley metal case, which I have to carry anyway, so there are no extras to be taken on the road, save the wall charger. None of the 4 mobile/car charging options that are included match my LG but it's a nice thought that no other company has tried to do. The included mini usb charger is great for my laptop or desktop to charge pretty rapidly. Please excuse my incessant rambling. Go out and get the 645 and at least try it. I like it and it has performed well for me. I will respond to this post after 3 months with an update. Peace
