I like my LG Tone Bluetooth canalphones. They've held up well (for a couple of years, IIRC) and the battery lasts all day. They charge via USB, so there are no batteries to change and you can wear them all day and plug them in overnight. They have built-in buttons to control volume, play/pause, skip forward or back, or answer a call. I use them with my Android phone, tablet, and PC. They're currently just under $50 on Amazon ($47.95 as I type this). The Amazon reviews seem to agree with me: They average 4.0/5 stars.

The only things that I would change are eliminating the blinking blue LED while they're connected (I've covered mine with black electrical tape) and active noise cancellation would be nice, but would probably add to the cost and decrease battery life. The passive noise blocking (i.e., the noise blocked by their earplug-like form factor) is pretty good, though, as long as you press them into your ears and get a good seal. If that's uncomfortable for you or if you need to hear the outside world, they will stay in if you wear them like regular earbuds.
