I have owned many different Blue Tooth ear phones and can finally report the best yet! I drive a truck as a part time job and its a very noisy environment. The Voyager is loud in my ear quiet as far as background noises and it has not yet shown a weak battery after a 19 hour work cycle! Odd look yet comfy guys check this one out! Plantronics Voyager Pro Bluetooth Headset | Superior Performance some online reviews posted: Simply the Best Message from Dave from Chicago - May 6, 2010 I've tried many other blue tooth products from quite a few different big name companies and this is the best I've found. It was easily paired and performs as advertised. I find it very comfortal and secure to wear. If I had any negative things to say it would be that for the price I think plantronics could have included the carrying case but then again if I'm not using it its on the charger anyway. Its simply the Best. Report this postEmail this Review Best Yet Message from David from Rexburg Id - May 6, 2010 I farm and am in a tractor and other noisy equipment. I have tried several other bluetooths including Jabra and they were unusable. I can hear great and people hear me great even with the door open on the tractor. I wear it 12-15 hours a day and it is comfortable.

I used to go through a headset every 6 months but this one is a keeper. Just had to replace the eartip as it broke off but that's probably because I keep it in my pocket when not in use.
