So ye, you raised the treble and bass to get closer to that V-shape sound you have in your DT990 ;)  I don't know if the DT990 are more/less detailed than the X2 but you seem to prefer that sound signature at least. 

From what I've read brighter headphones might appear more detailed than darker headphones.  What kind of eq changes did you do?

Any FR graph out there? 

  Even more places out of stock now. I think I missed my chance on the lower price.  

Is there going to be a Fidelio X3 sometime soon? I've noticed the price has gone from 280$ to 210$ in Sweden the past few months.  And a few places has stopped selling them. 

I have also had a similar experience in upgrading headphones. Not these in particular though.   Paying twice the price compared to my old headphones my expectations were high. So when I only got a marginal difference I was also disappointed.    After some more listening I started hearing...

Anyone has a pic of the white COP's with velours?   White ones are a bit cheaper and I think they would look cool. 

Yeea! Thanks for that, owe you one!

Received the shell kit today....and the nozzle fits!! =D  The rest of the parts look identical to the real IE 80.    Replaceable cable, replaceable everything, as long as the driver doesn't break these can last forever.  ...

Well the COP and DT 770 can't be folded either....Same with Mad Dogs

I think it comes down to whichever one you think sounds better.  COP has more bass and less treble.    I wouldn't think the difference in isolation would make much difference, especially in a library.    DT770 should be more comfortable because of velour pads.  But you can change the pads...

  Would if I could but...   Quote:

Woaa that's awesome! And just 20$ as well   Ye, if the nozzle doesn't fit it's useless of course. But I see no reason why it shouldn't... I think I will try. It would suck to have to throw away a pair of 300$ IEMs

Hi 5 could you make a quick comparison with your X2? I'm interested to know if they have more/less bass and treble.    I wish Tyll would measure these soon....

Nozzle came off while working, I have no idea where it is.  It doesn't seem broken inside though. Any ideas how to fix this? Attach a nozzle from a cheaper IEM?   I contacted Sennheiser but since I bought them 4 years ago, they probably wont repair it, or send me a new nozzle. Lets hope...

Alright, thanks for the help! =)

I just checked COP on amazon.com and its being discontinued?? :O   Aiaiai seems really interesting, have to read more about it.  I know a place which has the aiaiai but not the COP, so I cant do a side by side comparison.    That's interesting that the COP studio has more controlled bass...

I tried out the COP in a store yesterday, and really liked it! I compared it side by side with the m50x. COP had more bass quantity, m50x was more like a setting 2 on COP COP had a smoother warmer sound. COP was less detailed COP seemed more forgiving COP bass was softer COP was about the...

I know this is an old thread.    But it's interesting how you say that the highs are brighter on the COP than the DT770. Looking at measurements from Innerfidelity, goldenears.net and headphone.com that's definitely not the case.   I would have liked to try out the DT770 for the comfort and...

I don't have the M-100 but I've had the X2. I was really disappointed in the bass quantity. After some time I got used to it though, and found I did indeed enjoy the headphones a lot overall.    Were you able to at least determine if the bass quantity in the COP was sufficient?  I would...

For those interested in comparison between headphone jack (alc892) vs Sabre dac. Alc892 got more bass, a rumble which actually vibrate my headphones a bit..just a bit.  Sabre is clearer, brighter.   I don't wanna say any more at the moment but that's what I have gathered so far. The...

Thank you for the comparison. I've ordered a Sabre doc now.

Thank you!  Why not go with sabre for home setup? Because it doesn't have as many input/outputs? I'm trying not to spend too much. Of course I don't want to buy a bad dac either, that I feel the need to upgrade, that's just waste of money.

This guy measured it to 200ohm http://www.head-fi.org/t/678798/hifimediy-sabre-usb-dac-uae23-and-audioquest-dragonfly-brief-comparison Have you tried the sabre DAC connected to the x2 without the O2 amp? Does it sound as good without? Are you saying the sabre is as good as the dragonfly...

Clieos mentioned in a thread that the sabre DAC had an output impedance near 500ohm and that it won't be as good of a source as it could be. What does that mean? What specs am I looking for when buying a DAC for the x2? I think I read that an amp for x2 got to have less than 1ohm output...
