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.
The first time I saw the term online was in 2006/2007, long before people started making videos to try to trigger it.
That’s impossible, the term didn’t exist until 2010 when Jennifer Allen created it because she wanted a “scientific sounding” term to describe the sensation.
