Sennheiser HD-25 70th Anniversary

I have the original HD 25-1 (made in Ireland) and listened -vs- this new pair. The oiginal sounds much more balanced, clear, and less hyped in the low end. I really thought it would sound the same. Too bad.
They say it's the "classic HD 25", but the sound signature is completely different. This new pair has a modern "bad headphones" smeared sound. It's hard to tell where anything is sitting in a mix. Everything is just in your face with a huge unnatural bass that is super hyped and not accurate at all.
My old pair has lasted for 10+ years of use. It sounds much, much more accurate when listening to reference tracks that I know.
Really too bad. I wonder why Sennheiser, and other brands think people who could use this in a studio or even for DJ use would want to hear the bass so incredibly wrong. These headphones are getting returned.
