I have the same problem. For reference, when I wear bike helmet, I wear 62cm. Baseball cap size is XL or 7 3/4. I currently use Nova Pro 7, but the mic quality is not the best, and the sidetone has static noise. I have been using it for 3 years and looking for new one with better sound quality, mic and sidetone. Prior to this, I was using Sennheiser HD 598cs (same as 569), it's comfortable, but mic wasn't great and its wired. Here are the headphones I bought and returned due to small size. (either too tight or don't cover my earlobes) Logitech G Pro X2, Astro A50 gen5, Turtle Beach Stealth 700, EPOS H6Pro open, HyperX Cloud III, Nova Pro Wireless , Nova Pro 5. Drop PC37X, Sony Pulse, Sony Pulse Elite, Sony H5 Inzone. The only one that fit my head comfortably is Asus ROG Delta II, but the app is too buggy and sidetone didn't work for me.
I haven't used a gaming headset in about 15 years. Went from Sennheiser HD298s to Sennheiser HD558s, to my current cans, Sennheiser HD6XXs with defenestrated sheepskin velour cups. They're incredibly comfortable and despite daily use for about 5 years and a total of 5 house moves, they're still holding up with zero damage. I've paired all three sets with Antlion Modmics and have never been let down. I goddamn love this setup. Congrats on the killer set of cans, OP (phrasing)
I wear my Sennheiser 598 (open can) for like 16hrs in a row with glasses on sometimes, and they remain comfortable throughout. My ears get kinda uncomfortable if I wear my 598C (closed can) for more than a few hours in a row
Sennheiser HD598. I think I got them on offer for around £150 a good 15 years ago. They opened my eyes (ears) to how headphones could offer greater fidelity than HiFi speakers at a much much cheaper price point. I've since upgraded to the 6XX which is a clear step up for music even if not quite as comfortable. Seeing the 599SE on Amazon for £99 today makes me happy that a lot of people are going to be experiencing that same feeling for the first time.
Sennheiser 598SR headphones bought 2017 Pleather earpads and headband flaking. Earpads are easily changed out and wrapped the headband with grip tape. Both done twice.
I have a Sennheiser 598, 599, 560, 600, and 650. All are open back. The 598 is a little dull on the top end to me. The 599 and 560 are both very well balanced and very similar in range and coloration, with the 560 possibly pulling ahead just a bit. The 600 and 650 are not really brighter, and are both more power hungry than all of the 500 series that I have. They are however both more responsive and cleaner sounding with a decent little amp on them. The 600 is flatter, and the 650 is a little more colorful with more of a V signature and a slightly subdued high end. I don't think that the 500 series are especially intrusive to others as far as sound leakage goes as long as you keep them turned down when you are too close to someone else. My favorite of all of them is the 650 with fenestrated leather pads that increase the bass response slightly. I think that the 599 may be a good choice for you if you just exercise a little bit of discretion in setting your volume level when in close proximity of others. The last time I saw them on Amazon, (recently), the black HD599 SE could also be purchased for right at $100. I think they are both a good choice and a good bargain, all while being very light and comfortable.
