Author here, and I have the same pair of Sennheisers too! Wonderful headphones, and I did some mod where you remove some foam inside the earcups which effectively makes them like the next model up (not sure which guide I followed, but this [0] might have been it). As I mention in the article I'm not a fan of Bluetooth, though I do use that on mobile devices. Some have better connection and codec support (depends on Bluetooth version and phone too). I have to say the Corsair wireless headset I reviewed and use, has been quite good. Audio quality in terms of wireless is great, never a problem there. I haven't tried to specifically measure lag, but nothing I noticed at least. So I can compare more directly with what you know in the HD555. The Senn's are more comfortable (lighter, a little softer in all places) and have a clearer, more natural sound, to me. The Corsair's sound good to me as well, but tuned differently (as I wrote, more multimedia focused). I haven't tried equalizers, but that's always an option. The wireless freedom is great. I use a wired keyboard and mouse at the desk, but headphones always have a wire moving around the desk, getting caught on something, or just annoying if I want to get up and move a little in the room. Happy to answer any other questions. For me, the Corsair hits a nice price point and quality, works well for what I want. The higher end wireless ones quickly get more expensive, and I'd imagine that money would get you more in a non-wireless set, at least in terms of listening quality.
