The cup is plastic.  If you have to do that twice a day, I believe that the thread on the cup is gone.  Return and exchange for a different unit if you bought new.  Gluck.

The threads aren't on the cups themselves. There is an insert (I think it's brass) in the cups:
 

 
  
Check the screw itself first.  The screws are really soft so I wouldn't be surprised if the threads on the screws got messed up.  If so, then HiFiMAN can send you replacement screws (they are a propitiatory size unfortunately, so you can't just get some at a hardware store).  If the screw is fine, then the threads on the insert themselves may have got messed up.  For that you'll probably have to send the headphones to HiFiMAN.
 
But, if you just want a quick fix, try putting Loctite on the screw and screwing it back in: http://www.loctiteproducts.com/threadlockers.shtml

Thank you for the advices, guys.
will check it out.

Been listening to the CALG and the FAW Noir with the HE-500 and I'll have to say I've been expierencing pure audio ecstasy these last few months.

Hey guys, I've asked Koiloco and my cousin, but I just want to see what you guys think. When attenuating volume, I know most people say to keep the source at 100% volume and adjust on analog to avoid reduction in bit depth. My cousin, however, explained that the signal to noise ratio affects how much attenuating you can do on the windows volume control in that if you listen to something like 100db peaks, the signal to noise ratio on the emotiva is 95db, meaning that you can attenuate somewhere around like 5db through windows volume control (i'm not sure if I'm saying this right, but I'm hoping you guys understand what his point was).
 
From a realistic standpoint, at what point would I really be getting a degradation in audible noise?

Just got a HE-500 and wow! I has almost the perfect tonality for me with the Blue Dragon cable. This is out of an o2 so it can only get better with a better amp.

Now get yourself an Emotiva mini-X a-100 for it and enjoy!

You are right about losing resolution when using digital attenuation. Analog attenuation is continuous and is not affected by quantization. Generally you want the signal coming to the amp as hot as possible without any clipping or distortion on peaks at either side, windows or the Amp''s input stage. The thing is, what do you mean by attenuate by 5 dB at the windows side? And how will you know when you've really reached that 5 dB point? Windows hardware varies and your line output level is probably not going to be a sure shot.

 Just picked up a pair, will be here in a couple days... dammit. So next month I'll be in here again complaining that I bought the Emotiva...

I'm looking to get to a store in my area (ann arbor) either this weekend or next to audition the He-500s.  Very exciting as my current pair of headphones are (much cheaper) Sennheiser HD555s from about 6 or 7 years ago.  Just have to wait for the store to get some he500s back in stock before i try it.  My cousin has the He-400s which I've played around with a couple times and I love them, so I'm hoping the he-500 will just blow my mind out of the water.  It would be the most expensive headphone I've touched... let alone listened to and (probably) buy.

ericeng91 - which store carries these around A2? I'm thinking of upgrading to these as well. also let me know which amps you've been looking at. thanks in advance

You guys know HiFiMan's online store (Head-Direct.com) has a 30 day, no re-stocking fee return policy right? All you have to do is pay for shipping back.

 

[nacc]

thanks ben_r_ i didn't realize that!

Mainly loud speakers, but (at least at the open house) they had a corner set up for desktop amps and headphones.
