No sound differences.

The cables themselves may be wired wrongly (or it was some kind of special tired ear placebo case, which actually could be the case...). I've replaced my HD 6XX cable with the original 3m cable. I've been mainly using HD 6XX which I got shortly after HD 58X. Besides, my HD 58X is sub 5000 batch...

I've come into conclusion that all I need is HD 600 and/or HD 650 to be happy - those two just sound right. I might buy the actual HD 600 and keep the "HD 580 Jubilee hack job" as portable variant.

Hmm... I'm fairly certain that the cable that came with my HD 58X is wonky. Right side connector has out-of-phase/polarity flipped (not matching the connector markings). I switched to one that came with HD 6XX and it doesn't feel like stereo image is messing with my head any more. Also it felt...

Soo... Just got mine. Everything sounds very good, just right. I went the cheapo way and reused my HD 58X Jubilee shell (this is one reason why I love HD 6xx series). Very happy that I did. I've loved my HD 6XX and I preferred them to HD 58X Jubilee and HD 660 S but I'd say that this edges HD...

Now I technically own the full set... These are not HD 58X Jubilees (though, I guess the name makes sense now, eh?). I have hard times noticing any differences between these and my HD 6XX. :spy: Hard to say which I prefer... or more like which I love more. EDIT: Actually... I think I like my...

By the way, I've been swapping between HD 6XX, HD 660 S and HD 58X on the fly and HD 660 S is by far the most different sounding while HD 6XX and HD 58X are much closer (except when it comes to actual performance). Also HD 660 S is by far the darker sounding which I find a bit weird since...

Mmhhhmm... I can't really get over the recess in 2-5K range. Mine sounds like things are coming from under the ground and lack of clarity vs. my HD 6XX - can't really explain it any different when swapping between the two quickly. Also the large dip before the 6K makes sibilant sound more...

They definitely seem to put subpar pads in Drop batches...

Generally speaking I likely listen at lower than average. I had to lower the volume quite a bit from my AE-5 (32%) and the a lot further on my O2 at unity gain (around 10/11'o clock). When using HD 6XX that is, with HD 660 S I have to further reduce the volume down to ~25%. Sibilant sounds are...

Separation imaging is definitely more drastic on HD 660 S - good thing for gamers. Sibilance is something that raises its head with HD 660 S. It's rather interesting... To my ear HD 6XX is brighter without sibilance while HD 660 S sounds a tad sharper but also not as bright but has overly...

Just picked mine. It's the new variant and I must say that the new moulds are indeed rather nice improvement. No seams and stuff like that and other small changes too which makes it look more premium. Remains to be seen which is more durable (haven't had issues with the old ones though). I'm...

Studios tend to use closed headphones and something like HD 650 costs truckloads more than something like Sennheiser HD 280 Pro. People who do their stuff at their home studios would likely not use Sennheiser HD 280 Pro.

Grabbed HD 660 S from sale (379 €). It's probably one of those headphones that I should have bought ages ago. It was 50/50 between it and HD 700 but unfortunately I made a mistake. Now it will complement my HD 6XX and HD 58X. I'm not sure which version it is, could be the older variant since it...
