Rating : - Great bang for the buck
You totally get what you pay for. With moderate expectations (knowing these are not going to give you the greatest sound you have ever heard from a set of headphones) these are really great.

I used them a few times last season, and they were awesome. Took a bit to get them to fit just right, but I left them in for good - they are so low profile they don't bother me in the helmet at all.

Knowing that riders who wear a helmet will most certainly be wearing riding gloves, I may have made the volume switch a bit easier to use for gloved hands, but otherwise, they work great!!
