alright then, I'll do my best. the HD280 Pro is very good, extreme isolation and fully circumaural, so the hard clamping force is well atenuated. The problem is that these are true monitoring cans, so bass is not the most impactful, too thin to the usual musical use. Have a informative listen on them here, very helpful link: http://www.sonicsense.com/blog/headphone-shootouts/which-headphones-are-best-listen-here-for-yourself#audition100headphonesonline. and for isolation level, check these graphs: http://www.innerfidelity.com/headphone-data-sheet-downloads
another one: http://www.amazon.com/Beyerdynamic-DTX-501P-Lightweight-Black/dp/B0091TA5EW these are very small, with an excellent case, and rather good sound (perhaps too much highs, if you are sensitive to them like my these are a poor options, otherwise they are good. not great, but good).
the V-Moda M80 is at sale now http://www.amazon.com/V-MODA-Crossfade-Noise-Isolating-Headphone-Shadow/dp/B00I9UKKS0/ref=sr_sp-atf_image_1_2?s=electronics&ie=UTF8&qid=1405123483&sr=1-2&keywords=m80 lots of punch, exciting sound, not neutral but not Beats bass level. a tad over the right amount of it, simply put. Comfort is the biggest concern, over 3 hours it starts to hurt. Even if the isolation is put on second plan for the sake of soundstage (these cannot coexist in this price range) and the case is rather huge for the size of the headphones, a good option to consider.
and then the always mentioned Logitech UE6000, now for 99$ or even less. these were sold for over 200$, and were higly regarded at that price, so you know they are a steal right now. if the size isn't too big for you, definitely a option to consider. btw they almost have two different headphones in the package, a neutral one with the NC off, and a bassier one with the NC on. http://www.amazon.com/Logitech-982-000104-6000-Headphones-Discontinued/dp/B0094S379U/ref=sr_sp-atf_title_1_1?ie=UTF8&qid=1405124338&sr=8-1&keywords=ue6000
at last, at least for now, the Koss PRODJ100 Tony Bennet version http://www.amazon.com/Bennett-TBSE1-Signature-Edition-Headphone/dp/B005K5I9QW/ref=sr_sp-atf_title_1_1?ie=UTF8&qid=1405124087&sr=8-1&keywords=tbse1 these have a case + removable cable, so the extra 20 bucks over the regular version are well spent. Excellent headphones for rock due to the speed, highly recomended to change the stock pads for the real M50 pads. lots of reviews around here
hope this helps, and good luck!
