Wow.

HD6XX (but I'd probably smuggle my HD600's under my jacket just because). I can never decide which I like better. It truly depends on the genre/song.

I have a pair of HD600's from 1999 that still sound perfect. In fact, they sound indistinguishable to my buddy's brand new pair of new-frame HD600's once I changed the pads out. The paint on mine is worn out, the clamping force is basically gone (but oh my god they're comfy, and if you need...

I stand corrected on two of my points, but no need to be rude. Apple’s official website doesn’t have a lot and as a previous Apple employee, I don’t rely on things unless it’s on apple.com

No mention of replaceable parts like earpads. That’s somewhat alarming at this price point and, knowing Apple, they probably aren’t replaceable. However, I bet you can buy AppleCare so just get a replacement if something goes wrong. Good enough for a couple of years anyway until AppleCare runs...

Absolutely. The only characteristic that the Orpheus had that the HD650 lacks is the soundstage. Imagine an HD650 with HD800S levels of soundstage and you have the basic idea of the Orpheus. I'm oversimplifying it of course, but it's the closest I can remember. I distinctly remember not being...

I heard the Orpheus extensively at a CanJam event years ago. I think it sounds like the HD650 and HD800S had a baby. Super super beautiful midrange, silky highs, nice mid bass but a huge soundstage. Overall, an amazing headphone. I'd say a well-amped HD650 would be the closest.

I had the 800S... and I just couldn’t get into them. They remind me of a super wide, super clear, less-bass version of the DT880. You’d never know they were even made by the same company that makes the HD6– line of headphones.

The HD6XX and HD650 (newest chassis with squared-off edges) is identical in sound. I had both at the same time and did many blind listening tests and could not tell a single difference between the two. Maybe the clamp force was ever-so slightly less on the HD650. Maybe? That's it.

I had all of them, from the HD580 all the way to the HD660S. In the end, I kept the HD58X which is very similar sounding to the 660S, but smoother with better bass and the HD6XX, which is just an HD650.

I'm very happy with the Asgard 3 with my HD6XX. The Asgard 3 is ever-so-slightly V-shaped which compliments it well.

HD6XX and HD58X

Absolutely. All 300-ohm Sennheisers need power. On my Asgard 3, which is around 610mw@300ohm, there is zero veil. Just smooth, buttery, detailed highs.

Your entire 33 post history is just you complaining about Sennheisers. Are you that dude on YouTube who keeps posting those incessant frequency response graphs?

The HD6XX/650 is whatever positive superlative you can throw at it. It’s simply astonishing, especially from a price/performance perspective. I listen to my headphones 6-8 hours per day and the 6XX are the only ones I can do that with. Comfort, and that insanely great liquid smooth sound...
