Nice review - although FWIW I haven't found the Triples to be as bassy as you describe. My sine-wave testing indicated that (at least to my ears) they were essentially flat up to around 4700 Hz., with pretty good bass response down to 50 Hz. or lower. (I actually have a small bass-boost in my EQ settings for them.) I've used the Triples for a couple of phone calls, and other people's voices sounded fine to me.
Could this be a difference in the tips we're using? I'm using SpinFits.
I'm actually finding it very interesting to see the diversity of people's reactions to these 'phones - some describing them as V-ish, others (like me) finding them fairly flat; and even someone perceiving a pronounced deficit at the same frequency I found a noticeable peak. Assuming that the 'phones themselves are a basically fixed quantity, we human types are kinda weird! <g>
P.S. My own listening preferences are probably different from most peoples: a lot of (mostly acoustic) jazz, a lot of Indian classical (sitar, sarod, tabla, flute, voice, etc.), and assorted "other". Nothing techno, and (other than a bit of Amy Winehouse) nothing with hugely emphasized bass-lines.
