TO my ears I had 6XX for 2 years and didnt sound like 650 i am 100 % sure i had so many times side by side , and i was so curious why everyone said they was the shame ? compared to 650 , 6XX was warmer more muffled ... Thats why i kept only the 600,650,660s , i always thought that even 650 sound warm never sounded muffled to me .
I fully respect solderdude and his work , but in my opinion pads do have big difference the new Clear ring ones sound better , and last longer and have more space inside .
No because there are located in different countries....
Sure, cost need to be cut somewhere...No because there are located in different countries....
However I have a new extra pair of new pads that I can put in 6XX but there is no reason since cannot compare directly.
I understand that the 58X driver is not the same with the 660s in order not to cannabilise sales. But the 6xx says 650 in the box and they had in the past also the original presentation box. To put so much effort to change the driver in order not to cannabilise sales...???
Or most probably they do use not the best drivers from the hand picked production and the result is somewhat different.
In a lot of ways I did like the S2 more than the S, I found it sweeter, more liquid, and technically better. But I do think the S does have the edge on the mids, the original S is probably my favorite HD 6xx headphone in terms of mids. I do know what you're talking about with something missing as I did notice it to a degree myself, I thought it was the upper mids, but other headphones I own with just as if not more relaxed upper mids proved it's not that to me. I do want to try them again in the future on very different gear, etc.
Well, that depends on the acoustic space too, actually. There are a number of headphones that experience a phase-cancellation dip in the midrange, such as many of the Beyerdynamic headphones. These don't act like minimum-phase devices and actually have a FR dip due to outgoing sound (bouncing off earcup/head) cancelling out the incoming sound in a range where the enclosure would be resonant. The midrange in any such headphone will not respond well to EQ, as increasing the incoming sound will increase the reflected sound canceling it. This usually presents as a pronounced dip in the frequency response. Typically in the 2-4k range due to the internal volume of the headphone earcup.
There’s a persistent metallic graininess that is exciting at first then becomes grating.
Yeah I did notice that, also noticed the bass seemed to fatigue me as well. The treble never got less annoying with use like it does on Tesla Beyers (becomes a non issue with use and once you adjust at least on some of them). Honestly to my ears the HD 660S2 sounds like the HD 650 mixed with the T1.3. In fact it was the T1.3 that ruined the S2 and made it kinda pointless in my headphones stable. I ended up replacing the S2 with an HD 650 as that fit in better with my other headphones. I already had the S when I got the S2. Fatigue, the sense it's lacking something, and it not fitting in my headphone stable caused me to let the S2 go.
I’ve heard enough headphones to know that bass or in fact any part of the sound frequency can in fact fatigue me. I can tell the difference between fatigue caused by treble and by other frequencies. Some headphones simply create uncomfortable pressure at certain frequencies that wear on me with extended use, it’s not necessarily related to the presence of the frequency. Sometimes its the system that exasperates this. And it’s not a listening level thing as I listen at lower to moderate levels.I hear no such "fatigue" whatsoever. And I'm very treble sensitive and enjoying the little extra the s2 has. Bass fatigue?? There is no such thing.
