I use my Bose QC25s. Great cans. I use my Bose SoundSports for jogging.I was wondering what kind of headphones iPad owners use with their device. Do some of you use audiophile grade headphones? Or just some mainstream under $100 headphones. I ask because I intend to purchase Master & Dynamic splendidly crafted MH40 ($399) and wondered if other owners go for the hi-end and what results they have.
