Summary: I love how the pc part plug in stores in ear piece. It looks like battery can be replaced which is un heard of from most head sets. And connects to phone great. I also use them to watch movies. Great product so far. They were in the computer headset isle.
Summary: I had an H800 at my former job as a Project Manager, and I used it 10-12 hours a day on business calls. This headset is fantastic, in fact I required my new employer to provide me one as a condition of my employment.
Summary: It should probably be cheaper. But it's the best in this category I've used so far.
Pros: Lightweight. Long battery. Fairly durable. Bluetooth AND USB dongle.
Cons: If your car is super noisy, it may not be QUITE loud enough. I have a very noisy car though. Also, It's very easy to lose the USB dongle. Figuring out how to pair the bluetooth was a little challenging, until I googled it.
Summary: This headset works well with Skype, Lync, and GoToMeeting. Has a 40 foot range, holds a charge well, and is easy to setup. I have to turn up the volume all the way up (to 50) to hear well, but if there is limited background noise this is not always necessary.
Summary: Love how easily I can go from my laptop to my smartphone. It's super clear and the range is awesome. I can go from my office area on the 3rd floor to the kitchen on the 1st floor with no problems.
