Won't say anything about sound quality . That's for you and the rest of the internet to figure out, but it gives you options and any way slice it that's better.
Couple notes on install:
- Once you remove the ear pad and felt/foam dampening from the headphone driver, be sure to apply paper decal sooner than later. You don't want anything getting into the driver, this could be very very bad for your headphone.
- The paper decals are not specific to a side, but they do have a top and bottom. The cut outs in the decals are shifted towards the top of the decal and the holes on the headphone driver will be shifted towards the top of the headphone.
- Cell phone light helps for placing vent tuning cover.
