I got my pair of HD250 linear 600ohm in 2014 and they're still in very good condition now. It's my favorite sennheiser model now. For amps these years they're a little bit difficult to drive well.

anyone knows anything about those models would be nice. I and several fans are making a podcast about audio equipments in china called "sonic pilots". we wanna make a series of episodes about the old and untold stories in 1990s.

I'm a Chinese and I owned a pair of DT901 second hand. In very good condition and I loved them so much. There's a group of Head-Fiers in China who love old productions from German & Austrian very much. There's a story about Beyerdynamic's factory in Hoffenheim, at the years about 1994-1997...

best closed-back headphones for pop & old school rock music. but for me the bass is a little bit too much. thx for sharing.

Amazing!

HM-602...hmmmmmmmmm, here comes the hifiboy :D
