I think you might have had a defective one too, but that other hype thread is just way out there with some of their claims. I seem to be the only voice of dissension (or reason). At $70, it's great, but I'd be pissed if I spent $100+ on them.

Got cn11 Mikros 90 in. Thanks mang!  :)p5. To me the cans do seem to have bass in them, but perhaps less than other cans I have around with me. I tried some tunes, and even some test tones @ 500, 100, and 40 Hz. All the tones were perceivable in the Mikros, but 100 and 40 sounded a little attenuated vs what I got w other cans like my KSC-75s and HD600s.

Here are the mesurement results I got:

FR



CSD right



CSD left



Distortion right



Distortion left



These don't seem to have that much of channel imbalance. Again, the bass is there, just a little attenuated. These are also a little hard to measure, positional sensitive, and require good seal, so that is that.

Marv is giving them a shot too.

4k might be OK. 6k ringing is more scary. I just got these in from UB. Will take a listen.

I tried it because I haven't found a portable I enjoy. If you like some Grados (SRs except for 325is) and need more isolation, you might enjoy these. They're a little bright and colored, so guitar and vocals sound pretty good but not piano or orchestra.

Position is important as ultrabike's measurements show. Based on their sounding better toward the front of the ear, maybe the blue line should be considered the true measurement. They also need a lot of burn in for the brightness to subside enough.

When you say you have the headband tilted forward to get moar bass, how much are we talking? Do you have to wear the headphones like a Geordi visor?

 8) Funny. I hadn't tried that. I would say at most an inch.

The bass improved but the bigger improvement is they sound more open with the sound angled into the ear. There's a trade off in loss of isolation. But they're still somewhat bright and genre-specific.

They make treble-rich rock sound good, but I needed something more versatile for portable use because I wouldn't carry more than one pair with me and switch based on the genre.

Just adding cn11's Mikros 90 impedance plot...



Fairly close to the ~26 ohm impedance claimed in the specs. Could be I did something wrong but seems fairly resistive. The 3 to 4 kHz driver resonances are a bit interesting.

Also, cn11 provided an Auvio 3.5mm cable that works great as a replacement/alternative cable for these.
