When I've bought SR80e just out of curiosity they were alright. Not the best but pretty decent for the price. Have their own pros and cons and very fun sounding.

I sold them and it appears they were the only headphones I regret selling. I was missing them so much so I sold my Sundaras to buy SR325x and I love them.

They are not ideal, not neutral by any means but they're the only headphones which make me dance every time I am listening to it. They're so energetic, engaging and lively sounding so I can forgive them any imperfections.

Will see what the new Sennheiser headphones lineup will be. Their recent wireless offers was pretty meh. So I don't really trust in corporate bullshit statement they have released.

I actually haven't seen HD6X0 in any tech store so far.

*Had. Sennheiser has sold their headphones division last year to some hearing aid company Sonova.

I agree, when I got my HD6XX they definitely didn't live up to their hype. They have amazingly good mids and accurate and natural tonal balance, which make them ideal headphones for playing human voices (like audio conference call, or listening to the talking heads on the Youtube), but for music listening especially if you are into something hardcore, like Grange, Garage, Anything-Metal, EDM or Rap, they are disappointing. For classical music I would also prefer something else. For $200 there are plenty of really good headphones like AKG K702, Grado SR225x, Beyerdynamics DT880Pro, or even HD560 to concentrate so much on HD6XX.

I am a drummer and while listening to my toones, I focus specifically on drums which are living in the corners of the spectrum - sub-bass (bass drum) and highs (cymbals of any kind) and HD6XX is delivering neither quantity, nor quality of those ranges.
