Does anybody know what year the DT150 was released ? Just curious....really enjoying them. The ultimate statement in substance over style. Most people wouldn't give them a chance based on looks alone but lots of good stuff to unleash re sound.
I'm not sure exactly. All I've heard from someone who knows a lot about Beyers and headphones in general and has been in the headphone game for well over 20 years was the 1980's sometime, but I would likely have to call Beyer and hope to find someone to talk to who knows the exact year when it was released.
The history on some of these older and vintage headphones can be very hard to find sadly.
This link gives the history on some of their headphones and company, but sadly nothing about the DT 150s release date. The design of the DT 1990 for example is actually a homage to the original DT 880's design. The Amiron design is a homage to the ReVox 3100(which is a re-branded Beyerdynamic's from the 1980s).
