Hi, so I picked up of these little satellite radio today, for the intended use having on longer mtb rides. I have one for my car and love it, so I thought it would be great to have a portable unit. This unit is nice as it as it has the option to download and store music, but I really only plan on using the satellite radio feature. But the problem I see so far is that you have to use these bulky antenna headphones which won't work while wearing a helmet. Something I didn't know before purchasing. Anyhow is anyone using this radio with earphones / earbuds other that will fit with a helmet??? I did some searchs online for other types of earphones, but didn't find much. Thanks for yor feedback!
