jea i didnt feel like dishin out mad dough for tuneups sp instead i created my own and the cost was completely free........Heres how
MATERIALS-
-Knife(stole it)
-electrical tape(found at soccer practice)
-old headphones(none earbuds) i used pair my dad got 4 free on plane
-sewing kit(free from hotel)
-super glue(found at house)
DIRECTIONS-
1st get your old earpads from ur helmet then poke in the inner vent on it(it was really easy for me cause my helmets a year old)then put your finger in and wiggle thru to the bottom wear you want the cord to com out, now take a nife and guide it thru with ur finger and cut along the seam until a big enough hole for the headphone to go thru(do this for both earpads) Now take apart the headphones(the plastic covering on mine just snapped off)and remove foam pad so that only the actual speaker is left. NOw that the headphones are dissasimbled wrap electrical tape all aroun it(except for where the holes for the music to come out are)This will secure all the parts and wires. You are now ready to instert the headphones thru the holes you cut earlier. It will be a snug fit so just push it into place where the vent is facing inwards. Try to tape it down everywhere possible for more stability(if you want i gues you could glue it)now where you popped in the vent reglue the outer part and stick where it once was. The final step is to stich up the area on the earpad where it was cut so it looks good as new(make sure not to puncture cord!)and Vwalah you have your free tuneups...
