Replying to Giro g10 MX / TuneUps II

Im lookin to get this helmet and am curious from those who have tried the TuneUps II how they feel and how they sound (I have an iPod). I am debating on whether or not to invest in a new helmet or just use some Skullcandy SkullThumpers and a beanie. However, I doubt the skullthumpers ability to stand up to powder shots and falls.

Listening to everything from Tom Petty to AC/DC I want to know if the TuneUps II provide decent, crisp sound with a nice bass that doesn't sound underpowered. I'm not a huge audiophile, but I also dont like muffled guitar solos.
