After getting into this hobby, the first headphone I actually felt comfortable replacing my old "Gaming" headset daily driver with was the Mod House Audio T60RP Argon.

It is insanely comfortable (including pretty deep pads), has a soundstage that is fairly big, especially for a semi-closed back (but it's also conventionally wide, easily beating for example the Sundara), imaging that stretches a bit to the width of the soundstage but remains precise, and a sound signature that is a lot of fun, with a tastefully executed v-shape.

These make anything sound good, which is why I like them for things like YouTube where cheap productions and compression could otherwise be a problem. With that said, they do have a somewhat artificial timbre, and they lack a bit of clarity as well as bass "speed" compared to what I would hope for with a planar at this price point - they do come in at "upwards of $400" with a price of $479 once you add the pads and strap - which you absolutely want to.

While I personally really enjoy the Argon, you could also check out other less severe (and thus cheaper) T50RP/T60RP mods, or maybe just a T60RP with custom pads or something (you could even get the Argon's pads on their own).
