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.
I would have sworn you were wrong, but I guess I assumed that it was around long before I learned the “correct” term for it. Turns out I just learned it at the same time everybody else did, basically.
