  1. AKG K275 Over-ear

    The AKG K275 will cheerfully perform in more use-cases than AKG will suggest. Early comments on this AKG K275 were largely welcoming to this 50 mm dynamic closed-back headphone, featuring folding hinges for relative portability given the big circumaural pads. As a fan of my AKG Q701 that uses the same mini-XLR connector, I bought a set of the K275, hoping to maximize cable flexibility.

The Oppo HA-2 is similarly Apple MFi certified, portable DAC/amp.  The iPure-20 is a (now old) desktop DAC/pre-amp providing...
