I've had a pair of Able Planet's Sound Clarity noise cancelling headphones for a while (for grad school), but I only paired it up with my Touchpad for the first time last night. Holy crap it sounds impressive! For reference, I run a set of AV123 Rocket 850s with one mfw-15 in my livingroom. Just sayin'. The TP and these headphones provide a real audiophile level experience! Good stuff!
