Plantronics .Audio 645 USB Behind the Head Headset Review

Because of the sound quality for both the headphones and the mic, plus the convenient volume control, I will buy a new pair if I cannot repair my last pair. The first incident involved the entire left earpiece falling off and hanging by their wires. I found no way to put it back together so I had to superglue it back on instead. I had no further problems for a year when the mic quit working. I opened it up and found one of the two mic wires pulled free from the solder joint. What happens is if you rotate the mic boom completely around the mic wires get wrapped around the post that connects the boom to the headset, rotate too far and they will break. This is a design flaw in that you should be prevented from being able to do this. However that break didnt happen until 1.5 years of owning it and I had easily put 500+ hours of usage into them. Also if using the USB connection instead of the analog one, you will need to use a "boost mic gain" option in the software if available. Im an avid gamer and when using USB had to boost the gain, didnt have to when using analog...boosting on analog caused too much distortion. Although when using USB I was told the sound was clearer, jsut harder to hear when it wasnt boosted....not all software has a gain boosting feature.

BTW i used these right away out of box either USB or analog without any problems on Windows XP 64. I have not tried them on any other version but hear they work with Vista 32 and 64.
