For context: Comfort is my number 2 priority behind wireless for my current use-case (playing PC games on my OLED TV ~12ft away) and I am likewise a bit apprehensive about my Penrose X pre-order due to comfort. At heart, I'm a speaker guy, but I've had a lot of the mid-fi cans (AKG, Beyers, Senns) over the years for gaming and still come back to my original X2s for gaming simply due to the long-term comfort (I have a giant ass head and game primarily in long binge sessions). I did own and use the K702s w/ flat band and 65th annie pads (similar to K7xx sound sig) for competitive gaming for a while and I really liked their imaging. Their fit wasn't for me but I get why you and others find them really comfortable.
While I haven't owned the Artctis Pro Wireless specifically...I have bought and used the Arctis 7 (which is very similar I believe) along with just about every other 2.4Ghz headset on the market (except Astros) at some point and they frankly all just sounded like crap. My close friend has the APW's for the battery swap feature and I've tried them at his place a few times. They sounded nearly identical to the Arctis 7 I had, to me. I would legitimately rather have a pair of $15 Koss KSC75 than any of the 2.4GHz headsets from HyperX, Arctis, Corsair, or others when it comes to SQ.
From a comfort perspective, the Arctis 7 I had last year were actually quite light with very light clamp force (they kind of just hung there from what I recall), but the pads were extremely itchy to me personally. I never looked into replacing the pads because of the sound quality issues, but if I were going to keep a pair of Arctis that would be a day 1 change for me. That said, I suspect that the lighter weight of the APW, the more breathable pads, and the headand will outclass Penrose for long-session comfort for most.
The problem from my perspective though is the price of the APW. I personally can't see myself spending APW kind of money for <$50 sound. Even if the Penrose end up squeezing my head and I return them, I'll use my BTR3k dongle for aptx-low latency bluetooth and get a mod mic wireless before I go with a different 2.4ghz headset. Now that I think about it, if I had known I would be PC gaming primarily from a couch and not at my desk a year ago, I would have bought a pair of RS 185 before they were discontinued and paired it with a mod mic wireless.
Headphone Manufacturers: if you are reading this, somebody please make us a pair of open-back RF wireless cans again. Also, use a tower transmitter like Sennheiser did with the RS series so we don't have to deal with poor connection from USB dongles.
