Neither do I....but there it is.
A mysterious Tyll appears.

Haven't seen much discussion about the CAL! as compared to the DJ 100. Love the CAL!

Doesn't seem to prevent other headphones from being brought into the fray :-P

Yes, usually to point out how ProDJ is superior to them. biggrin.gif

Huh. Well. I can think of a few things that would cause this but without knowing the testing methods they remain idle speculation.

I think it's ear pad resonance, and I do think it's a real measurement, but it still perplexes me. I've checked the calibration a number of times...al looks good.

Resonance is one of my suspicions. Not the pads but the air trapped inside. Air in closed or constrained spaces has interesting resonant characteristics -- it's how some musical instruments work smily_headphones1.gif. My M-100 gets this awful resonance when a commuter train pulls into Back Bay Station, some interaction between the headphones and the engine noise in the tunnel. Breaking the seal makes it go away. I don't recall anything like this with my DJ100 or DJ200 so if it's happened it's not repeated enough times for me to remember.

Open headphones won't do this because... open.

Like I wrote a few days ago, Mikros 90 is an on-ear headphone and thus inherently inferior.
Hm. Harman Kardon CL is another on-ear. Inherently inferior.

Take it with a salt lick smily_headphones1.gif.

Huh? Not meaning to knock the DJ100's, but the Mikros 90's sound quite a bit superior to me (although comfort takes a hit). Have you heard them?

 

Also, are you saying that all on-ear headphones sound inferior to all over the ear headphones?

On-ears hurt after a few minutes. As in sharp pain, not merely discomfort. Given that? Most on-ear headphones do sound inferior to most over-ear headphones to me. There are a small number of exceptions on both sides. Koss KSC-75 clips don't bother me much while Skullcandy Aviator is a torture device.

It doesn't matter how good Mikros 90 sounds or what it costs. Wearing will hurt. That makes it junk.

JVC HA-S500's are some seriously great sub $50 headphones for an on ear.

Working around the building to some Infected Mushroom (B.P. Empire & IM Supervisor), I still had them on for a 1/2 hour after the music stopped, so I guess it all depends on the headphone... biggrin.gif

Ok. I'll just have to remember that whatever you say is your opinion only.
