Pros: Picked this up with a coupon code for only $10! Works very well. Automatically shuts off quickly to save battery. Accurate. Seller included a hand written letter, which shows he is taking a personal interest in my satisfaction. Well packaged, and arrived in about a week - not bad since it's coming from China!

Cons: None

Overall Review: Get this, you won't be disappointed!

Pros: sound pretty good, lots of different ear plugs for different sizes, different uses, etc. Stay on well as you pull a full face motorcycle helmet over.

Cons: volume button/microphone part started shorting out. Can only hear in the left earbud, unless I gently squeeze the volume button, then it sounds fine, until I let go of the button, then it's back to left ear only. Emailing polk audio next to see what's next.

Overall Review: I've tried a few now to use riding my motorcycle, and these are the best I can find so far. I hope the mic/vol button won't force me to move on.
