Another new owner here. Ordered Monday from Amazon at $70 and got them yesterday. Can't beat that. Anyway, what follows is sort of a stream of consience first impressions. For reference, my main stereo has Martin Logan Vista's with two SVS ultra subs. Headphones on hand for comparison are Sennheiser 580's (oldies but goodies), Grado SR-60's, Ultrasone Pro-650. I also use Ety-ER6, and HiFiman RE-400 IEM's. Used Microsoft Surface and my second generation Zune as sources to this point, with a short stint on my iPod 5G. Waiting patiently for my Super Geek Out.
First the bad news. For me (large head) I'm having problems with the fit. All the other cans above are way more comfortable, especially the 580's with their soft velvet pads. The clamping force is high, but more anoying that that for me is the way the earpieces rotate towards the front of my head which ends up putting most of the pressure on the jaw muscles in front of my ear. It's not a deal breaker for me, since I listen to cans for short segments of time as I usually take them off several times an hour to leave my desk. My wife however said they were comfy so those of average head size probably will think I'm nuts. I'll play with stretching and bending the headband to try and change the angle it hits my ears.
The sound does remind me of my Vista's minus the subs. Nice and clean, and certainly the best mid and treble of all the cans I have here. There is a bit of a cupped hands type of coloration and a little bit of grain in the treble that I hope will disappear with break in, but it's not objectionable. My other cans sound thicker in comparison. Acoustic guitars and orchestra are very good with the Mikros. Actually everything I've played so far sounds good with these.
I haven't come to a definitive conclusion about the bass. This is of course subjective. At this point the 580's a and the Pro-650s seem to make string bass, and kick drums sound a little more forward with slightly more resonance to them. The reason for this is their bass is a bit "looser" for lack of a better word, but does sound maybe a little more real. However the Mikros bass is tight and well defined.
Perhaps the bass will losen up a little with break in. The one impression I keep coming back to is that initially the bass seems slightly constipated.
It's there, but just quite can't make it out to my ears.
All in all, I would say first impressions are quite positive. The clairty is better than I expected and with some break in and stretched headband, they will do nicely for me. Overall I think they do stand up to Martin Logan's claim that they sound like their speakers. If anything changes after they get some hours on them, I'll follow up. For now they are definitely keepers sound wise and a real bargain at the current prices.
Happy listening,
Chuck
