I got an Aeon X Closed, overseas I might add, and the right channel is like -15dB right out the box. Luckily Drop handled it wonderfully. So I was wondering what is the general consensus about Dan Clark Audio headphone's quality and longevity? I've had close to 30 Hifiman headphones myself or sold on with warranties and had only one case needing replacement. Anecdotal of course, but just makes me think.
