GENERAL COMMENTARY:
Beyer velours
- cold and Beyerish-sounding, not a good match
- very comfortable, imaging considerably worse than Hifiman velours, considerably more closed-in soundstage in both width and depth (height is the same) in comparison to Hifiman velours
Hifiman velours
- more natural-sounding than Beyer pads... quite similar but with no subjectively unnatural emphasis in treble region
- quite comfortable after a while (more tough than the other pads but no sweating and becomes softer after a short warm-up time)
Hifiman pleathers
- generally a bit warmer than Hifiman velours but difficult to call it "universally better"
- quite comfortable but almost immediately cause sweating, subjectively feel a little shallower in comparison to Hifiman and Beyer velours
HIFIMAN VELOURS VS PLEATHERS:
BASS: Velours > Pleathers
- velours offer a bit emphasised subbass which I find very nice
MIDS: Pleather > Velours
- pleathers offer a more full midrange, making the overall sound more "colourful"
TREBLE: Pleather = Velours
- pleathers are more forgiving and clean in treble, velours more clear, detailed and airy... choose your flavour
SOUNDSTAGE DIMENSIONALITY: Velours > Pleathers
- due to more airiness and maybe toughness of velour pads, they provide slightly wider soundstage... in terms of depth, I would call both equal though there could be some miminal differences depending on the song you are listening to
DETAIL: Velours > Pleathers
- because of more pronounced treble, velours offer a little bit more of the final detail... still, pleathers offer plenty of detail on their own
IMAGING: Pleathers > Velours
- somewhat, pleathers offer considerably more accurate imaging...
BLACKNESS OF BACKGROUND: Pleathers > Velours
- due to less airy treble and/or more solid imaging, pleathers are able to contrast every instrument or voice better
(Note: As both pads come close to each other in all aspects, there are no >>> differences... just > ones
)
I personally see both Hifiman velours and Hifiman pleathers as equal sound-wise... It just depends on what you want. On the other hand, the only thing I like about Beyer velours sound-wise are the circular fillings provided with the pads... They definitely have a potential to slightly decrease airiness without influencing imaging or decreasing sense of openness too much. So far, I may even prefer them to my DIY felt circles I have been using until now.
