There really is no comparison. My Jabra BT135 Headset is the lightest little flea to sit on your ear through a whole day.

Afterdark Black, Ski Patrol Red and Moss Stone Green.
* Up to 8 hours talk time and up to 170 hours standby time.
* Lightweight and comfortable - weighs 14g.

If you are in the market for a little headset like this you must choose the Jabra. Tons of other lookalikes and similar do not have the out-of-the-box ease to use as does the Jabra. I know, I have one! Would not swap it for anything else.
