HD 550

Maybe a Beyer 900 pro x. Semi-open, good imaging, natural stage. Also, designed to be plugged into mixing equipment; very easy to power A 560s is also a great starter option. They have better sound separation than the Beyer, but the imaging is less precise. You can find them for half the price of a Beyer, but you will need to invest in amplification, so the price works out to about the same For a closed back option, the Ft1 is the current pound-for-pound budget king If it was my money: I would skip the 560s and go for an HD 550 (better drivers, better tuning, better comfort), and pair that with an entry level signal chain. The Magni Piety is my top pick in the $200 range, but good luck finding one as they're out of stock year-round. A next-best option would be something like a Schiit Fulla

I have had the 550 HD for a few days, and I have had many, is that sound outside the headphones moments where I took off the headphones to see if the sound in a game was outside, like a plane or strong wind etc.

hd550 is a fairly affordable and safe pick imo. If you don't mind eq the 560s is another good set. If you love vocals get something from the hd6-line. HD660S2 can be found anywhere near $400 these days

hd560s if you want something cheap, hd550 if you can pay a bit more, hd620s if you have hd550 cash but want close back, hd600 if you like vocal and don't mind paying a bit more than hd550, hd660s2 if you want something warmer and doesn't mind paying extra. It's all about budget and preferences

Wouldn’t recommend it honestly, the 600 sounds way more tame and laid back, and has pretty poor imaging. It’s a reference headphone meant for studio use. Get the HD 550 instead

I love metal.  I love my HD 550. I use primarily with my PC.  I also love saving money. HD 550 looks to be on sale right now for $200 USD. That’s a fuckin’ great deal. 

I also agree on all points! My HDB 630 hurt my head after a bit the first few times I wore them, but after a little while they stopped hurting and now they are super comfy. I can wear for an 8 hour work day no problem. (I did nothing to reduce clamp force other than just wear normally.) My other headphones are the HD550. Not quite as clampy from the get go and the sound is amazing too.
