I think the line between audiophile & what’s subjectively enjoyable to each person based on preference is often blurred. I don’t like most things classified as ’audiophile’ (except my jds element)

I recommend looking into IEMs if you want more of a ‘wow’ factor, plus they’re often cheaper and easier to drive efficiently. Another benefit if you try some IEMs is I always gift extra to friends since they aren’t outrageously priced and anyone can get great sound from their apple dongle. I’m currently satisfied with tygr 300r for over ears and ikko OH10 for IEMs. The Ikko’s block out 100% of outside noise and are insanely wide & immersive.

Shp9500 is in your budget. I’d also check out some IEM’s if you’re open to the idea of in ear

Yes to both. Check out some youtube reviews on them. If you’re not mastering music the 770s are too analytical IMO. Tygr’s are fun while staying accurate. Nice low end for open backs

Tygr 300R if you have another mic or toss a modmic on top

I’m not here to stop you, but rather to get some clarification… airpods are actually satisfying the ear of an audiophile? 😵‍💫
