At the current selling price, these represent a good value. At the original retail price of $300, there are likely better choices when it comes to sound quality. Interesting style and design that will appeal to some. They certainly look distinctive and are well made.

Sound quality:
In general, I find the sound quality to be enjoyable. Some have complained about the bass. I find the bass adequate. Many headphones these days have exaggerated bass. Detail is good. Mids and highs are good. I don't have a lot to complain about the sound. No part of the frequency spectrum jumps out to me as wrong or distracting. I like all genres of music, but it's unforgivable if the voice is not reproduced well. The Mikros 90 does a respectable job with voice. I do not like the scooped mids and exaggerated bass and treble that a lot of headphones have these days. The Mikros 90 thankfully does not have a U shaped frequency response.

I can see how some people might find these a little on the tight side. If you have a big head, then they may exert too much pressure. I find them comfortable, but these are not all day wearing headphones.

Build quality:
Solid. Nicely packaged. I can see they were trying to go for the $300 price point. So at their current selling price of under $100, these represent better build and aesthetics than your typical $100 headphone.

I like these headphones. I can understand why some are more critical, but when current price is factored in, I don't think there's a whole lot to complain about. Not the reference quality ML may have been aiming for, but still a good set of headphones that doesn't do a whole lot wrong. If you like full, emphasized bass, these are probably not for you.

I think some of the negative reviews of this headphone are a bit off the mark. These headphones have a wonderfully detailed, accurate and rich sound. The treble is delicate and never harsh or strident sounding. The bass, while not pounding is detailed and has impact and definition. I did audition these at a local Best Buy, and from the listening station in the store, had initially dismissed them, especially in light of the retail price of $300. The sound was flat, unremarkable, and a bit congested, a sound signature I felt it shared with the B&W P5. However at the current selling price of under $80, it was worth a Black Friday whirl, and I anxiously waited for my MLs to arrive as I read through the few online reviews I could find.

I have auditioned at length many entry-and mid-level headphones, including the B&Ws, Beyerdynamics, AKG 550s, Shures, Grados, and V-Moda Crossfade 80- and 100s. I personally own Sennheiser HD580s and Momentums, Sony MDR-V7s, and a few others. I listen using an Aune X1 DAC/Amp (another nice bargain product) with high quality music files. I have been listening to the MLs everyday for a few weeks now, and they sing oh so sweetly. They have a nice sense of space and air, especially for a closed headphone, good noise isolation, and do not have any extraneous microphonics from the headband or cable. Perhaps I am lucky, but I find them very comfortable, although they do clamp more tightly than my Sennheisers, the headband stretches over time.

Bass is impactful, but not rumbling. Note changes at the low end are clean and detailed, bass lines are easy to follow and track, which is not easy with all headphones. The midrange is clear with nice sense of space. Vocals are recessed but natural. Treble is glorious without harshness.

Superb headphones, full of musical detail and energy. In fact, some of the very best headphones I have ever heard. Overall very refined in their presentation, the Mikros 90 may be generally better suited for cerebral listeners than visceral listeners. For my listening tastes, however, the MLs have served ALL my musical choices very well. Getting optimal placement can be tricky, but once achieved the Mikros 90 really deliver.

Bass: solid, balanced and extended with excellent pitch definition and impact. Can be Stygian and prodigious with the right recordings. No midbass hump here.

Midrange: detailed, clear, coherent, tonally complex and saturated. Vocals are rendered with breath-taking realism.

Highs: detailed, clear and extended with no glare (unless the recording itself is glary). Excellent sparkle and finish on tambourine, bells, rider cymbal and high brass.

(As for the reviewer who said the highs and lows were "soft", I'm not sure what headphones he was listening to. My guess is that they were not properly broken in. These headphones require a long burn-in. Judgment should be reserved until at least 100+ hours are over. The Mikros 90 undergo quantum changes over time.)

Soundstage: recording- and equipment-dependent. Can assume strikingly large 3-D proportions. The music floats free in space with no sense of closure/constraint. Superb separation within, and delineation of, the performance space. Excellent resolution of massed instruments and vocals. These headphones allow you to hear deep--and I mean deep--into the details of the recording.

The MLs scale up extremely well. On my home rig the Mikros 90 even give my HifiMAN HE-6--which run balanced, straight out of my speaker terminal outputs(!)--a run for the money!
