Ya these pads are worth the money spent.. I am trying them with my ATh velours. IT opens up the sound even more so it seems. The ATH pleathers are not bad but I think I prefer the velours. Either way I think you guys will be impressed with what these pads does. Who don't want a full over ears version.. These pads are as easy as just throwing them on over your HA-S500 cups. I know guys be stitching a bit of the back end to close the pads. There are a bit of sound variances using different internal pads..So yes it is a pad over pad mod but overall these end up making your HA-S500 sound and feel like full sized cans. Amazing. lol. Just when I thought I got every bit of sound from my HA-S500.
$17 for these pads? Completely worth it imo.
