AKG K-271 MKII

The first thing that hit me was the material, which seems like brittle cheap plastic, that inevitably would need epoxy and duct tape to hold the headphones together. And after plugging them in I thought there was a problem with the connection or cable since the sound was incredibly weak, tin-can-like, with practically no bass.
Seems like a pair of €20 heaphones with a €70 AKG logo.

Have used these for a cople years, I've found they don't have good enough bass which makes it hard to mix with these around the lower frequencies. They have lasted for more than 5 five years as I'm writing this, although the leather has dried out.
