Haven't seen a recent thread on this lately so I'm curious what Bluetooth headsets you guys use out there? Rate 'em 1-5, link 'em too if you can! I currently use: -Plantronics Discovery 975 5/5 -Plantronics Discovery 925 4/5 -Aliph Jawbone2 4/5 -Plantronics Voyager 520 3/5 1. Plantronics Discovery 975. I've got 2 of these actually one for my PlayStation 3 and one for my Droid. It's the main Bluetooth headset I use these days. Sound quality is excellent. It sticks in your ear with no hoop, is comfortable to wear for long periods of time. It comes with a little leather case with a battery built in so that you can recharge the headset up to 3x when away from AC power. Has a little LCD panel to show you charge of both devices. (Infinitely easier than deciphering how many blinks equals what battery charge!) Best voice. You may see them on this seasons "24" as it's the headphone of choice at CTU 2. Plantronics Discovery 925. Earlier version of the 975. Great for call quality, battery life etc. Comes with same little case. Design is a little different but it gets the job done. No LCD screen on the case. Mainly used with my work Blackberry. Uses MicroSD charger, so you get an extra for your Droid! 3. Aliph Jawbone2. Much smaller than the original. Very tiny and chic. Great sound quality (it uses a little nub to detect vibration in your jaw to know when to isolate outside noise (using it's patented NoiseAssassin) so you could be on a crowded street and still be pretty clear. Only downsides are the battery life isn't amazing and the proprietary charger plus it only comes with a USB. (Becoming less of an issue these days as I'm starting to acquire a ton of AC USB chargers) 4. Plantronics Discovery 520. My original work Bluetooth headset. Does a decent job but is a little bulky. The ear hook makes it a bit uncomfortable to wear for long periods and not quick to get on. Has a proprietary weird shaped charging port. Battery life was average if that.
