switch from giro and get a red helmet, sometimes any model can be compatable you just gotta check it out, i got the sw helmet from 2 years ago and its compatable with the new hi fi this year so test it out
yea, the tune-ups are great, if you crank your pm3 on the gondola, it makes for good speakers. the mute button i find goes in an unusual place(i have it under my collar) so i sometimes bump it and it mute.
07 tune-ups will be wireless with buttons on the ears for volume control and such. it will also work as a wireless hook up with your cell phone. the ears will also detach and will come with a hook up so you can use them as regular headphones too.
My Giro Tune-ups are dope, I have the nine9 helmet, they let me hook up my 2-way radio for backcountry and are made by skullcandy, the sound is very good.
