1 out of 5 eggsNo wonder it has to sell at deep discount

Pros: Looks like well made headphone

Cons: awkward headband both band and ear cover tend to move, extremely uncomfortable upon putting it on head let along for long time, impossible to make it feel better, very weak bass, best sound of it is treble but may sound harsh, I listened pop songs and classic music, never did I feel any rendered remotely near full sound

Other Thoughts: I can't believe the designer could have made this product go into market I can't believe any people at Martin Logan can allow this out as reference headphone. ML guys, please grab some decent headphone in the market in the $50-100 range and listen all of them and recall this one from the market. Redesign from scratch and test if you really want to make one headphone. I never owned any Martin Logan. Though the brand is not high end but it seems to be decent one for ordinary joes.I am only casual semi audiophile. I have a Sennheiser HD 650, RS 220, and a few more earbud and headphone in the range of $25 -- 200 and a few Creative and Logitech headphone, SONY and others at around $60 range. To be honest, this head phone overall is only worth $50 even with it's good look. I am considering return it because wearing it is like being clamped by a crab on the head. It made me not to want to listen anything.

4 out of 5 eggsNice for the price

Pros: They are nice looking and appear to be well constructed. Sounds Great for $59

Cons: If you have a large head they will fit tight, and may be uncomfortable if worn for a long period.

Other Thoughts: You just can't beat the price for a Martin Logan product.

5 out of 5 eggsA pair of headphones brimming with character and potential.

Pros: Build quality, SQ, particularly in sound separation, Mid-range and highs. Lightweight with good noise isolation.

Cons: Aesthetics isn't that great. Sure it isn't a bad looking pair, but if anyone unfamiliar with the brand were to see them, they won't make any particular impression. Fit can be a bit finicky, and can take some time to settle onto your ears. Does clamp on tight.

Other Thoughts: I just un-boxed them and am listening to them as I write this first impression. This isn't an in-depth review since they've been pumping sound for the last 15 minutes or so. From what I've heard however, they are incredible headphones for the price with lots of potential after burn-in. I own similar headphones such as the venerable Audio-Technica ATHESW9A as well as lesser models like the Sennheiser HD239 and Bose AE2. The Bose and the Sennheisers are outclassed by these headphones, which is understandable for the MSRP. However, these can be had here on Newegg for a steep discount on the right moments. When I saw them here on sale, I grabbed the chance since they had garnered good reviews on Headfi. Yes, there are some bad ones as well, but the critical deciding factor for my decision was price and the fact that the good reviews were overwhelmingly good from some reputable members. That was enough for me so I don't regret the decision. These headphones out of the box scream potential. The sound is nice and balanced, with a clean mid-range that is forward and intimate. The instrument separation is good, and the sound is full, and not overly warm like the Audio-Technica. The lows are a touch light, but are actually nicely balanced and neutral similar to the AKG Q701. I love bass, but I can easily appreciate the sound from these headphones. Compared, the Sennheisers despite being excellent and well balanced, feel lacking in detail and sparkle. The Bose. Well, they're pretty much toys in comparison. These may be the most affordable pairs of headphones you can buy for critical listening if you buy them at the right time. If you see them on sale, GET THEM. For their low price, you will not find a better pair. Just listening to these pre-burned, I am excited to see what they will sound like after a proper burn-in.

3 out of 5 eggsNearly Good...

Pros: Great Sound
Great Price
Pause/Resume works with Android, which is about the best one can hope for in a "Not Designed for Android" world.

Cons: Fit is TERRIBLE. The pads literally role forward off one's ears, no matter how carefully positioned. They simply won't maintain a proper position/seal if worn as intended. However, there's a potential work-around...

Other Thoughts: I DID figure out that the person who designed these must have REAR-FACING ears. If the headphones are REVERSED, L/R, then they actually fit very nicely, if a bit snugly. Of course, with L/R sound channels also reversed, that's a separate disaster. But, I've located a 3.5mm M/F L/R Channel Reversing Adapter which promises to cure the problem. We'll see. If not, I'm savvy enough to rewire the headset itself, though I'm hoping to avoid a such tedious endeavour. For $60, I consider these a good deal.

4 out of 5 eggsBest Value in High End Audiophile Headphones

Pros: Highs are outstanding...They are really sweet and extended. Midrange and Lows are good. Decent soundstage. For $57 these are the best headphones out there. I have used with Audioquest Dragonfly and CA DacMagic and LittleDot III headphone amp.

Cons: Comfort sucks big time. I couldn't wear more than 1 hour. They clamp my head and it really hurts.

5 out of 5 eggsAwesome

Pros: Sounds Awesome, even before break-in period. Good sound for the price. Comfortable.

Cons: None so far other than a shorter cable than I would like. No big deal.

5 out of 5 eggsMikros 90: One of THE Best Out There

Pros: Detail, clarity, spatial realism, extension, balance and an INSANELY affordable discounted price.

These scale up extremely well. Pair them with your best gear and they will summarily bury ALL the competition in their class.

A truly REFERENCE quality set of cans.

Cons: Martin Logan will probably not design/release another set of headphones.

Other Thoughts: Those who give these headphones a bad review have probably not broken them in [they need close to 200 hours to really open up/settle down IMHO]. Or they did not position them correctly, or they listened with lousy sources.

These are some of the very best headphones I have ever heard. Period.

1 out of 5 eggs

Pros: None that I found - I could wear them for longer then 10 min.

Maybe great for a small kid 7-13

Cons: small, bad sound, clamps your head. I'm not an audiophile but these are bad and that's sad because I love Martin Logan. This ended up being a $25 loss for me after RMA.
