This morning I put on the stock pads again and this is interesting. There is a small effect of the velours. They seem to smooth out the highs a bit. I put the original pad on the left while keeping the velour on the right. Listening to some tunes I am familiar with..
The highs seem to be just a tad lesser on the velours. Same mids, same lows. It was the highs that had just a little less presence..But overall the sound is very much the same with same dynamics.
Thank you for all your answers regarding HA-S500. While at earpads comparisons - how much worse is isolation with Senn velours than stock pads ?
If per any chance I end up using these for monitoring while recording, any n-th increase in isolation is welcome - but the increase in comfort looks tempting too. Please try listening to the same music on loudspekars at your normal listening level, once with velors, once with stock pads - without signal in phones of course. Is there a significant difference in isolation in any part of the spectrum between the two or it is more linear, just one having more sound from the speakers coming through than the other?
