Trying out my AKG 240 mk ii's today and WOW. Sound is responsive in all ranges. Smooth, clear bass. Excellent treble response and a crisp high range, but it isn't super full of bright sound, which I think some may or may not like. That said, I can actually listen to many of my favorite Miles Davis albums without any clipping of the harmon mute he is famous for.
Comfort was improved with the velor pads.
Only con is that the headphones should be branded as OPEN, not semi-open, because I can hear everything around me. Not a huge issue, but I might get a closed set (like the SRH-440s or ATH-M50s) as my next foray into "audiophile" class products. I hate that word. You don't have to be an enthusiast or a specialist to appreciate good audio.
Overall these AKGs are a solid choice and come with a spare cable and pads worth over $50 retail, so consider that as a good value added.
They will require some amplification to get the most out of them, but I didn't buy them for mobile use.
