Before buying my AKG's, I agonized over my headphone selection. I had a pair of Sennheiser HD 475's. They sounded great, but the leads were fragile and didn't last long.

I tried higher-end Sennheisers, but once you get above the $60-range, Sennheisers just aren't worth it. I tried Grados, but they were horrendously uncomfortable. Finally, without even testing them, I took a gamble on AKG's sparkling reputation.
Once I got my cans, tho, I quickly found the drawback to owning a pair of headphones like these: you can hear every flaw between the 'phones and the performers. Problems with the recording, problems with the record media, problems with the stereoall these things become painfully obvious. Once you have these headphones, you will feel compelled to replace the next-weakest link in your system.
UPDATE: this review pertains to the 240S headphones. The difference between the 240S (studio) and the 240M (monitor) is the impedance. The 240Ms are high impedance headphones. They're great at what they're built for, but they cannot be effectively driven with low-power devices like computers, personal CD players, or iPods.
