Here's a very simple project I've been meaning to do for a while, but couldn't find headphones that were small, cheap and loud enough. I finally found this Panasonic RP-HT21 headset on Amazon for less than $5 (http://www.amazon.com/gp/product/B00004T8R2) and decided to try them out. Well... I'm glad to inform that they worked out perfect with my Giro Shiv helmet. Audio quality is excellent and they are loud enough when paired with my iPhone (I found the volume loud enough at like 3 steps down from max).
Note though that my helmet's ear flaps were already setup to use the optional Giro TuneUps audio kit, so I didn't have to modify anything there, but nowadays most helmets are setup similarly for optional audio kits.
Anyhow... here's what I did. I think the pictures are pretty easy to follow, but feel free to ask any questions!
Materials & Tools needed:
- Helmet (Giro Shiv used)
- Small over-the-ear headphones (Panasonic RP-HT21)
- Hot glue
- Craft foam
- Optional: iLuv iPhone remote adapter
