Pros: Good assortment of ear buds. Through testing them I was able to determine the two best options, one slightly better for voice, one slightly better for music. The fit was MUCH better than I was anticipating based on some iffy reviews, but I was very pleased, and I have a larger than average head. Sound was perfect for what I needed. I wouldn't run in premium audio head phones, anyway. It was very nice to be able to run without the wires, while listening to streaming audio of my choice on my EVO 4G.

Cons: None, until recently. Now when listening to music the bass seems to be overdriving the speakers and there is popping/chopping. This seems to have started in the past couple of weeks, which is particularly annoying because my runs are really getting much better.

Overall Review: I am not sure if it has anything to do with the Android 2.3.3 update that came out a little while back, but I will see what I can find out. My wife just got a new phone, so I will test with that one versus my EVO 4G
