I'm looking for headphones to play games on with the Playstation Vita and games/movies on an iPad. After reading dozens of threads, these seem like the winner. I'm looking for something less than $250 that has a short cable, is somewhat convenient to carry to and from work, is comfortable, and doesn't need an amp. Buydig has them for $210, and Ultrasone sells a 31 inch cable for $13.
Has anyone tried the HFI-2400's with a Vita or an iPad?
Other headphone suggestions are welcome, but please consider that these will not be used for listening to music.
