So I'm planning to either buy Grado's SR-125i or Alessandro's MS1i, and then quarter-modding the cushions. A few questions: 1. Can the mod be performed on both cushions? 2. Your input on which headphone I should buy: 3. What are these 'bowl' cushions I keep hearing about? Link to purchase if possible. 4. Would those bowl cushions work on either sets of headphones? More to follow if anything pops up. edit: 5. If I get the MS1i, I would probably end up buying the FiiO E1 for my Air Cushions. If I plugged my E3 - E1, would this do anything? I'm pretty sure it doesn't, but I just want some confirmations.
