Forget earbuds for snowboarding: they're tangly, uncomfortable, and the wires get in the way.
The best solution I have found are ZED-phones. Flat Bluetooth Speakers stitched into really good headbands and beanies. We got ours from www.ZED-phones.com but I think they're in stores too. They deliver globally for free anyway.
Sounds quality was good. They play a whole day straight without a charge. Standby for days and have a wireless distance of about 10 metres. Made by boarders for boarders they are the only decent options I've seen on any mountain.
would you or anyone else be able to expand on the sound signature of these beanie headphones? I've heard "good sound quality" but obviously good is a relative word, good in comparison to what?
