I find that wearing these backwards improves the seal dramatically.

  what What WHAT?  Are you kidding?  O_O

  Half that on Amazon.

I also grabbed a pair in that sale.  $35 after my almost-expired Egg Points.

  Indeed they are.  The comparison I linked covers their portability (lack thereof).

  If I may suggest, take a loot at the NVX XPT100.   My comparison of the CAL! and XPT100.

  Budget?

  The first pair was defective, but the second pair was indeed operating as intended.  Their treble is very overpowering with velour pads (more than any other set of cans I own [ I don't have the Superlux set mentioned above]) since the velour reduces bass / midbass quantity.  With the HTF600's...

  The warmness of the HTF600 flattens out into neutrality when you use velour earpads.  I am using the ones from my NXG HeadTrip NX-HTDJ...it was quite a squeeze to get them on though.  I also discovered that the NX-HTDJ sounds infinitely better with the HTF600's pleather pads...the NXG...

  Sigh...then either the retailer I ordered mine from is intentionally selling defective units, or NXG is re-branding Monoprice's factory rejects...or they just have godawful quality control.

Unless I received a SECOND defective pair, those NXG NX-HTDJ I mentioned earlier (rebrand of the Monoprice 108323) are VERY bright.  Almost intolerably so (brightest cans i have ever heard).  Yet again, the bass (which is quite light) is several decibels louder from the left cup than from the...

  Yep, they are actually cheaper on amazon in the US ($15.70 after shipping).  The first pair I got was defective...everything under 120hz came out of the left earpiece...very strange.  Some kind of impedance mismatch / not enough winds on one of the drivers?  No idea.  I'll be pissed if the...

  IKR...that's why I have 8 headphones:   Panasonic HTF600 - Good CAL! - AMAZING JVC HA-S500 - bad, even with mods / EQing.  Not capable of detail. Marley EM-JH020-MI - Terrible...until you mod / EQ them, to hell.  Then Very Good / Amazing NVX XPT100 - UNFRIGGINBELIEVABLE Koss KSC75 -...

  I highly suggest these for comparison as well.  They are a cheaper, yet upgraded, rebrand of these well-known Monoprices, which are constantly compared to the Panasonic HTF600.   By "upgraded," I mean they have velour pads and, a sturdier cable, and aluminum side-plates.

  Better than the CAL 1's?

I have to say...the NVX XPT100 simply blows the CAL away.  I did a short first-impression on the XPT100s several weeks ago, and I don't think I accurately portrayed the capabilities of these monitoring headphones - yes, these are indeed monitoring headphones, and damn good ones at that...

  So, in other words, the HSR-1000 is quite warmly tilted (I have the S500s as well)? 

Right off the bat, I notice that the NVX 100's bass goes deeper, has MUCH more impact, and MUCH better texture than the CAL!'s.   The treble is a bit rolled-off in spots (6500-9000 and after 15000), but can be improved by an equalizer with bands at 8k and 16k.   Clarity blows the CAL!s away...

My NVX 100s should FINALLY be arriving tomorrow.  I will do a first impression after a couple hours of use.

  It's design is for bassheads, no question about that.  However, I have to use almost equally extreme EQ settings to make my S500s listenable.

  I own both.  The S500 can't compete, even after they have been equalized.  The Marleys are particularly good with instrumental separation and have a soundstage that surpasses my Creative Arurvana live, as well as slightly less (but much tighter) bass, and less laid-back highs (they actually...

  If you have a 5-band equalizer handy, I highly suggest these headphones as a possible upgrade.  The EQ settings I use are -9 / -12 / +2 / +7 / +9.  My review at Amazon.
