A lot of people tend to dislike these cans. Some of them are right when they say the sound is a little veiled because the emphasis is put on low mids rather than high-mids, but that doesn't make these cans bad either. They take lots of power and put out incredible sound levels without distorting. They provide a good bass feel, but the bass hardly extends below 40 or 30 Hz. However, amping them correctly with a source capable of providing LOTS of current, will move those huge 50mm diaphragms in an okay manner even at 20 Hz. It does take a lot of current since those cans are rated at 24 ohms.

Overall, a very pleasant can to listen to. No harsh mids and very nice singing highs. It's not the best money can buy, but for closed cans that are loud, they do a great job. I should also add that some bass resonances may occur in the cups at EXTREMELY LOUD levels (think 120-130 dB). However, this is not a significant design flaw, as any closed headphones will tend to have resonances, only different resonant frequencies.

I would like to add that these cans sound better if you really CRANK them. This is not true with the 7506 which possess the same sonic qualities over levels. The 7509 sounds A LOT more balanced when levels are high (think 110 dB and over). The high-mids and highs become more apperant and the bass tightens enormously. At low level, these cans sound only average. The ratings I gave here are based on high-level listening. I'd give an average of about 4 at low levels because everything tends to become muddy.
