would like to upgrade or at least add some wireless ones to the fold

You can get the same ones baella has for $200 at mass drop. They are called the 6xx’s. It’s the same exact s*** just takes much longer to ship. I got those

Better than m50s

they do but don't buy the 650 you can get the 6xx for way cheaper and it's the same headphones but with a groupbuy

Yeah my personal opinion, there's different versions (ohms) I got the 80 ohm one that one was best if you listen to a lot of rap, has much better bass than the M50s, and is way more comfortable

I'd have to take off the M50s after a few hours because it'd start hurting, that's with wearing glasses tho.

I'd do your own research tho, read some reviews, look at some forums talk about it. Some headphones may be better suited for certain genres than others. Like the 650s above for example aren't exactly noted as being the best if you listen to a lot of rap, it has a more neutral sound or something like that.
