I replaced the pads on my AKG Q701 headphones today for the 4th time. It made me realize that I’ve used these headphones for at least 40 hours a week for 14 years straight. I’ve had to repair the left side speaker solder joint a few times, but they’re designed to be easily torn down and repaired. Truly BIFL headphones.
I’ve heard that the newer AKG K702 headphones are identical but I can’t vouch for that. They go for around $250.
As a fan of Hifiman headphones… good luck. Their reputation is more or less the opposite of AKG and Beyerdynamic for this sort of thing. I baby my HE-6 because they are irreplaceable.
