Recommendation for good bluetooth headset?

[h1r0ll3r]

So I got a new job where sitting in on conference calls is now a daily thing (yay). I'm currently using wired earbuds w/mic to sit in on these calls however I'd like a Bluetooth headset instead since it seems a little more convenient and so that it doesn't look like I'm purposefully ignoring coworkers. Not looking to break the bank on one but something that's relatively small and can be used for long periods of time. Last Bluetooth headset I had was when the iPhone 3G was new so, yeah, it's been awhile.

Anyone have any recommendations on a decent Bluetooth headset? Probably looking for something in the $50 range. Have no idea about brand quality or anything either so not sure if motorola or Plantronics are still good brands or not.

Thanks.
