Hi! I'm looking for some good full-size (closed) headphones that I could use whilst walking around in the noisy London and, at the same time, in the office. Mobile Gear: - iPhone 5 Office Gear: - Macbook Pro Mid-2012 I mostly listen to: - Rock - Blues - Symphonic metal - Classical Music Budget: Anything under £1k Thanks! P.S. Not scared of buying a mobile AMP/DAC stack if I have to!
