beyerdynamic DT-770 Pro 32 Ohm

In a nutshell: Great sound; ear cushions not as good as 250 version but still great value.

I've had the 250 ohm version of these for a while and use them for hours every day for computer, gaming, radio, and other miscellaneous household entertainment. They're light, very snug and comfortable, and completely surround the ear without touching. Sound insulation is excellent, granting a real sense of peace and serenity in an increasingly incomprehensible world. Sound quality is a little boxy, but this is the nature of the closed headphone beast. In short: muchos recommendeos.

So it was without hesitation that I purchased the 32 ohm version of the same model for use with field recording and roaming with my iPod. Less ohm resistance means more volume!

These 32'ers have the same sound, same great insulation. But they're a little less comfortable with the ear cushions being in black faux-leather. PVC, I would imagine. It's ok. Very good in fact. But the lovely fuzzy grey material on the 250 ohm set spoiled my precious princess ears so I was a tiny bit disappointed.

Seems a silly thing to be disappointed about, and it is. But we are irrational animals whose passions are governed by little details that irk. And sadly I, dear Reader, am no exception.

Glad to say that the musical response in the ears is still as clear as their big brother's and they perform their designated tasks with aplomb, nay, palpable enthusiasm. So yes I would recommend these as well if you need this ohm rating. They do "go to eleven" if need be without breaking up.

I wish Beyerdynamic would tell us more about the sonic differences between the different versions of this model. I honestly don't think they should all have the same model number.
This 32-ohm version is very light on bass, compared to the plentiful but not overpowering bass of the 80-ohm version. The mids are also more forward, making it sound more harsh. This may make it more revealing for recording and mixing purposes (not sure if it has an advantage there over the other versions), but it makes it less enjoyable to listen to, at least to me. The 250-ohm version (the one generally recommended for recording/monitoring/mixing) has about the same amount of bass as the 32 (actually a bit more, between the 80 and 32), but sounds smoother and less fatiguing.
On the devices I used it with (computer soundcard, external firewire audio interface, Samsung Galaxy phone), I did not find that the 32 gave me a lot more volume than the 80. If you don't want to ruin your hearing, the 80 go loud enough anyway.
