Hmm I think it's kind of different- when the term "clipping" is used distortion is usually out of control, not just audible (such as when the Elex's drivers give out somewhere between 104-114dB). In terms of tolerable listening, the HD650 is probably better for beyond 114dB, though you shouldn't listen for long at these levels. The Elex would be better prior to its clipping point though (<104+dB)A question. I was comparing the Elex review to this one and the high thd at 114dB of hd650 means it is clipping/peaking as Elex? Or HD650 still has some headroom?
Yup I just ordered an Aria as well! Iems usually have less bass distortion than open back headphones since being sealed and located close to the ear drums not much excursion is needed for bass to be perceived at appropriate levelsThanks! Yep, I don't plan to listen that loud, I'm just worried about how much headroom I have on HD650 to EQ its sub bass.
According to HD650 review at 88dB with some eq it is hitting 4.5% of thd and sometimes when mixing I pretty sure I play louder than that... BTW, I have been moving to Moondrop Starfield to check bass lines, it seems cleaner and well behaved, but I would prefer a over ear than in ear for "long" sessions.
The veil is no myth but is not lifted by the foam other than in the mind/eyes of the modder.

Wow that's really old! I heard biodynamic drivers degrade over time, but what about regular ones? Do the magnets lose strength?These measurements seem to be quite different from the usual suspects' and Amir's. Are these compensated? I am particularly interested in those of 2014 edition as mine are even older.
Thanks.
A decade would be a trial of time indeed. Other than heat and impact, what would damage them? I once left my earphones in their black shell case on the dashboard of a car under the summer sun by accident- there was a smell of burnt plastic and its sound had changed when I retrieved it T.TI suspect, but am not 100% certain that they use Rare Earth Magnets. “Rare-earth magnets and ceramic magnets are both types of permanent magnets; they are both composed of materials which, once given a magnetic charge, will retain their magnetism for years unless they become damaged.”
Oh yeah, just read that it's 80 degrees Celsius for Neodymium magnetsMelting point of the magnet metal to allow realignment of molecules. Drivers, wires, plastic components would be melted goo far before you reached the temps required to melt magnets. Some internal parts are pretty fragile and don’t like high heat. Anything over 130F and your chancing internal melting. Any of which could effect sound.
Haha well I probably shouldn't try to get credible 1-minute information bites from websites like these Temperature and Neodymium Magnets (kjmagnetics.com)High quality Neodymium Magnets are able to operate well in temperatures up to 212 degrees F. There is a gradual drop in magnetic strength when the temperature rises above 176 degrees F, but this loss in magnetic strength recovers when the temperature falls back to normal levels. As long as the magnet does not melt to the point of shape lose.
Okay I looked again and it seems to be a mistake on my part due to inexperience in the field. It ultimately depends on the grade of the magnets itselfHigh quality Neodymium Magnets are able to operate well in temperatures up to 212 degrees F.

I was in no way arguing your point. As you said it depends, not all magnets are equal. I was actually agreeing with you and did a poor job with my wording.Okay I looked again and it seems to be a mistake on my part due to inexperience in the field.

very different test method.These measurements seem to be quite different from the usual suspects' and Amir's. Are these compensated? I am particularly interested in those of 2014 edition as mine are even older.

It is not the HD700 drivers, but a new design sharing elements from it. The HD700 sounds quite bad by the wayThe HD650 has thrived for many years in the fickle audio market because it was superbly engineered to begin with. I'd leave it alone, especially if still under warranty.
The 660 appears to be a 650 retrofitted with HD700 drivers, at least according to Tyll Hertsens in one of his last Innerfidelity reviews.
I respectfully disagree about the HD700. It's a different beast to which I go back quite often. Be it mood or some album I just feel like listen the HD700.It is not the HD700 drivers, but a new design sharing elements from it. The HD700 sounds quite bad by the way
