  I do not think for a second they would repackage a return as new... it will certainly become a refurb at some discount but the question is how much and when :wink:

I agree, additionally I don't see any reason for Audeze to respond to baseless speculation bordering on slander. We really need to move on to the next subject.

OK, we can then rest in peace and trust Audeze.  I agree it´s a great company with a great customer service!

All of this talk of how returns (I'm not aware of any that have happened thus far) are treated is baseless and, in my view, irresponsible. Regardless of what people think of their headphones, Audeze is a reputable company full of great people. That's where the discussion starts and ends.

  So any owners experienced the mechanical buzzing / vibrations that Shembot reported, is this supposed to happen and does it become bothersome?  

 
It's not bothersome and has not affected my listening at safe, or even marginally unsafe, volumes with most music. I only have 1 track where it can be a noticeable issue at marginally unsafe volumes (and of course I can reproduce it with pure tones, again, at unsafe volumes).
 
Audeze is well aware of the reports, though it may actually be an issue of butting up against the laws of physics. The LCD-4 has extremely good bass extension, and it may not be possible with such bass extension and such a sensitive driver to eliminate all mechanical effects at very loud volumes. At some point you can't have your cake and eat it, too. As I said in my prior review, I don't suspect this will be an issue for most users, but since I put the headphone through its paces rather extensively (including using generated tones at different frequencies and volumes), I thought I'd make a note of it as a difference from other LCD series (and other planar) headphones.
 
Unless you like to listen to music with a very large amount of low-end energy at very loud volumes, I wouldn't let this affect your purchasing decision. I've decided to keep mine even though I do sometimes do that (and again, for almost all tracks I've tested in a wide variety of genres, even at loud volumes, there is no issue).

This may just be a side effect of the extremely thin nano scale diaphragm, as the HE-1000 (also nano scale diaphragm) exhibits a bit of this low end buzz (akin to a high end ringing) at very high volumes with generated tones. It probably won't ever show up for most people when listening to music, but it is a direct result of going super thin for more detailed and extended sound reproduction.

Which frequency or frequency range when using generated tones did you hear this slight buzzing?

I have not tried pure tones but check out the bass extension and speed with organs and cannons. The 4s hit the lowest of low notes with ease, the organs can go as low as 15-16Hz I think and any lower can only be felt. I also like to crank up the volume on the cannons, it is just fun to do that, would likely blow up my ear drums before I hear distortions.

The rate of the buzzing increases with frequency, so you can hear it at any frequency with enough volume, but it's easier to hear at lower frequencies. I used a 55 Hz tone, but the exact frequency doesn't matter. You can try a range of frequencies and hear the rate of the buzzing change as you change the frequency. I don't want to focus too much on this characteristic of the LCD-4, though, because it probably won't be an issue for people listening to music at reasonable volumes. 
 
It's important to note that this buzz is NOT distortion. There's zero audible distortion with this driver. It's a mechanical buzz that I suspect actually comes from the pins vibrating against the sockets in the connectors as you can wiggle the cables and make the buzzing cut in and out. Also, the buzz is not continuous with volume below a certain point -- it suddenly appears once you hit a volume high enough, and below that point, it's simply not there at all. 
 
I'm not sure whether Audeze can, or is willing to, do anything about this issue because it's really not an issue unless you're either trying to make it happen or listening at unsafe volumes.

ShembotCould it just be the drivers "bottoming out" at high volumes? I have heard this in Genis Towers as well, albeit at very loud volume. All transducers have their extension limits. Would love to hear more about its impact with music.
