Well he's gonna hate this then.
My vegan pads arrived and I decided to do some quick and dirty comparisons with my current grill modded/fuzzored HE6 and the stock velour and Focus pads.
For this I didn't fit the Hifiman pads properly with the ring flanges - just put each set of pads on the cups and let the headband hold them in place.
Cue face palm by ohhgourami.
Now, I know this is NOT the recommended setup I just wanted to get an idea of comparative tonal balances.
The recommended fitment for the vegans is via tape but at least they fit flush to the cups - the Hifiman pads contact was more uneven because of the protruding flanges on the rings.
Vegans did NOT have the felt ring applied as I thought this may exacerbate the darker balance with the magnet fuzzor.
I had the Senn HD600 as a control headphone to refer back to.
Results were interesting.
The vegans, no doubt disadvantaged with the magnet fuzzor, had darkest balance. Very 'midrange centric' - but that midrange sounded quite good. Deep bass was a bit MIA. Stage width didn't seem exceptional and that big prominent midrange produced big images, but not so focussed with the curtailed highs. Comfy though - yes, pillows for your ears describes the feel.
The focus pads - well I think I've already said these aren't my favourites for mid articulation and detail, nothing overtly bad though. Could get a bit 'shouty' sometimes. I noticed they sounded a bit compressed in width and general spaciousness. Bass deeper than vegans (in this setup) with some proper HE6 thump.
Stock Velour had the widest soundstage and most spacious sound. Best focus and instrument separation/placement too. Most detailed sounding - but sometimes to excess which could become tiring. Deepest, punchiest, bass too with the Lee Ritenour and Erykah Badu test tracks, not really effected too much by the loose uneven fitment.
Mids with the vegans could be quite lovely - though they tended to fare better with brighter material. The same material on the stock velour could sound too insistent - though I should note the stock velour balance was closer to the HD600.
The stock velour were usually my favourites when I conducted the above, non ideal, comparison.
Though as I listen further to the vegans, the sound continues to grow on me - sometimes switching from the velour the vocals on the vegans really 'pop'.
I think the vegans have greater mid clarity - vocals sound more realistic and substantial.
It's funny how, after adjusting to the balance of the vegans, switching back to the stock velour can sound a bit top heavy and lightweight in the mids.
Hopefully proper fitment of the vegans will improve bass and highs.
