I picked up a pair of the Martin Logan Mikros 90s about a week ago. The primary reason behind this purchase was to limit the use of universal IEMs when I'm working or watching stuff on my laptop.
I rather like these for everyday use. The build quality is good, the leather lined cups and headband together with the use of aluminum give it a bit of a premium feel. Aesthetics and materials used are not something you'd expect to see on a sub 100USD pair of headphones. The pads are comfortable and allow your ears to breathe quite nicely despite the pretty strong clamping force. I hope with time they loosen up a bit, they tend to hurt the ears a bit after a couple of hours of straight usage. The cable is removable and iDevice compatible. Personally I would have have liked it to be about 6 inches or so longer.
Not much by way of accessories. A nice carry case and a 6.3mm adapter is all you get. Would have liked to see a pair of extra pads and a spare cable, once again. for the price I might be expecting a bit too much. Also, I'm not sure if the pads are user replaceable, I haven't really taken a good look at them.
Positioning these headphones on your head and getting them to fit right is important. There is a very evident drop in sound quality if the alignment isn't done right.
Moving on to the sound, the mid range is nice and clear no real complaints here although to most people it will sound quite sterile and can seem to be a bit "emotionally distant".
These are not for bass heads. They are probably the most bass shy headphones I've heard. Tried them with the ALO International and it didn't seem to make much of a difference. I've heard things improve with burn-in, but I'm not the biggest believer in burn-in. Just in case anyone is curious they've had about 6/7 hours of usage thus far.
The highs are quite lovely on these things. They sound airy, especially for a pair of closed on ears. Instrument separation is great and they never sound harsh.
I bought these for about 145 SGD, they're available for 96 USD on Amazon (don't think they ship out of the US though). Overall I'd say they're good value for money. A good option for everyday use if you can live with the clamping force. They punch above their weight category but not to the extent that some posts on headfi would have you believe
