These are some great headphones for listening to in a RED helmet, or to and from the mountain in the headset. The sound quality is great. However, there are a few issues; one being that they are a bit heavy. So if you don't have them on your head just right while boarding with them in the headset not your helmet and you have a hard landing, they will go flying off your head. Another issue is that they make this really annoying squeak when you mess with them when they are fully pulled out, thinking about filing one of the parts down that rub against each-other. Have ridden with it about 10x so far, and have had no issues at all besides the minor ones above.
