Love my Hi Fi Helmet. I had zero issues with my Oakley Crowbar goggles fitting with it perfectly. The helmet fits very well, and the chin strap is comfy and easy to get on and off. The headphones are very loud, I usually turn my ipod all the way up and control the volume with the switch on the chord. The mute button is easily used with your gloves on to turn the music off to talk to someone or not to if they are trying to ask you where to find powder.
