New Headphones ~$100. Sennheiser HD280 Pro?

I hope I'm posting this in the right place, I didn't see any mobile audio or headphone forums anywhere.

I'm looking to replace my headphones, Maxell NC-II with active noise cancelling which have developed a frayed wire near the noise cancelling battery box, and I am looking to upgrade to something a bit nicer. After a significant amount of research, I am strongly leaning towards the Sennheiser HD280 Pro. It is vaunted as an extremely accurate and flat headphone, which sounds perfect to me.

The headphones are used for a significant amount of critical listening in an environment with unfortunate background noise. They are also used for music creation, and for that reason I would like them to be as flat as possible, avoiding artificial boost of any frequency range. The flip side to this argument is that I love my music full of bass, I listen to a lot of electronica. I also particularly like clear and precise highs.

The sound of the HD280 Pro is often described as sterile and antiseptic, which means it might be perfect for flat response when creating music, but it might not be very lively when listening to relax or enjoy. I've also had V-MODA Crossfade LPs recommended to me, but they appear to be a bit bass heavy and more a stylish accessory than for accurate sound reproduction. Does anyone have any input?

I've read quite a bit on that site actually. Their review was one of the major ones to sway me towards the HD280 Pro. The ATH-M50 looks very good too. I know it's very difficult to grade headphones by statistics, but the graph for the ATH-M50 looks very similar to the HD280 Pro, a bit of boost to the low range and relatively little drop in the higher register. The Sennheiser HD 25-1-II looks very good too, but it looks a bit less rugged (I listen to headphones falling asleep and that usually involves laying on one ear), and they cords aren't replaceable (again, due to falling asleep with headphones on I rolled over my cord quite a few times and I'm sure that's why my current headphones have failed). Not to mention they're more expensive.

There doesn't seem to be anyplace nearby where I am going to be able to try any of these headphones on. The music store in town is tiny and apparently doesn't have a headphone display. I went to target and tried on a couple of headphones, Beats Studio and Skullcandy Hesh. The Beats didn't have the noise isolation I wanted, were too heavy, and cost way too much. The Scullcandy were a bit flat on the bass sections. I threw the Skullcandy, Sennheiser, and Audio Technical in this graph to try and map out what's been discussed thus far:

It would appear that the Sennheisers do have a bit of drop on either side of 100Hz, resulting in very neutral sound, but still sounding a bit flat. The Skullcandy has major drop below 100Hz, as well as bad mid and high range response. The Audio Technica are very similar to the Sennheisers, except they have a bit of boost down around 100Hz. One other factor that I am looking for is isolation, since when I fall asleep listening to music I have my wife right next to me, and she doesn't want to hear the music. The Sennheisers are a bit better than the Audio Technica, and both are worlds better than the Skullcandy.

If I was lucky, I could listen to the two side by side, but apparently I am not so lucky... *ponders*.
