It finally died on me after about a year of moderate usage. As others have noted the on-off switch is quirky, and you would never know if it won't start, as if finally did. Sound qualtiy was actually quite good both ways, used with my RIM 7100t and with Skype using a Linksys Bluetooth USB adapter. A decent entry-level BT headset, but I am moving to a Jabra BT250v. will give a review of that when that arrives.
