The MFM Pro Model headphones are the ultimate mountain music technology package. For the first time ever, Skullcandy has released a DJ-style headset that includes a built-in, detachable MP3 player. This gives you the ability to listen to your music wirelessly through the MFM’s 40mm power drivers while also giving you the option to pull the player, slide on the battery pack, and transform it into a portable MP3 player that can be used with any headset. If you want a headphone that has it all, pick up the MFM Pro headphones.
