If I may ask, has anyone tried Sennheiser aviation headsets? For PC-use I use Sennheiser headphones/headset and compared to Philips which is the other main brand of electronics in my family then the Sennheiser sound-quality is very high, does that go for their aviation headsets too?
And for the nutty question, if you could get a converter for the jack-plug-sizes could a aviation headset work on a computer as well? (to my knowledge the two jack-sizes for aviation headset are both different from the two std. sizes for home audio).

I'm not sure about a converter being a good option for an aviation headset for use at home. I believe, for one, the voltages are different, though I may be wrong on that. I don't have a regular stereo system at home anymore, so my last recollection regarding such equipment goes back to the days of the... ahem... cassette tape and eight-track/LP record era... oy... now that dates me

My current system at home is a multi-speaker system tied in to my HDTV and TiVo unit, so there isn't even a headphone jack on it.
The other thing you may want to evaluate is that an aviation headset is geared to a given physical environment, and also for best clarity for voice communications, not music, though they can present music. Still, the optimization may be different if you are a true audiophile in terms of range response, lag, and midrange attenuation characteristics over a headset designed for stereophonic listening of music.
I have seen, by the way, converter plugs to go the other way, with a rectifier built into the plug, that lets a stereo headset be used in an airplane. I would be wary of that though, as the main use, other than communications, for a headset should also be primarily concerned with sealing out the dangerous decibel levels reached inside a cabin environment on a small plane. And remember.... hearing loss is cumulative. So, going too much on the cheap there might end up being paid for the hard way later in life.
