Arctis Pro Wireless (Legacy Model)

Id definetly look at what you'd want to spend. If its around $200 then get the Arctis Pros with the DAC. Probably the best youll find at that price point and the mic that comes integrated isnt crazy but it is serviceable.

I think the issue here is that you play on pc, which desktop mics are going to be a lot easier to plug in. Gaming headsets provide a plug and play experience, especially on console where you have to go through several loops just to get a DAC working. I believe that OP is on console, so advice for a desktop mic while doable isn't the most convenient and most definitely will end up out of the budget given. The maxwells have a strong sound signature but are way too heavy to be practical if you're not a big head. In my own experience, I ran Beyerdynamics on console for a bit and actually prefered my artics 5x, as the beyerdynamics were way to quiet especially for siege and as forementioned, getting a dac working on console just doesn't feel worth it. The headset was 16 ohms as well, so it shouldn't have been underpowered. Personally, i'm currently selling both the dac and the beyerdynamic headphones and will be upgrading to the artics elite.

I run the steelseries artics 5x (5p would be the playstation version) I'll be upgrading to the artic elite pro

I find the older style of the arctis pro much more comfortable than the artist nova pro. With third party pads and the more adjustable strap it's nice even if you wear glasses. 

Is he a big audiophile? That can drastically change the answer and increase the cost by quite a lot. If he's just looking to game online, SteelSeries has some great headsets for like less than half of your budget. I think I paid $200 or so for my Nova set. I had a Pro (9, I think) that cost about as much and I liked it more, but it broke. But I think that was my own doing. 99% of free time spent in discord calls with a partner who spent 80% of our time belittling me wore me down enough to throw it a handful of times. The SteelSeries app is kind of hit and miss. Sometimes you have to open it and manually select the headset, but not super often. I find that it doesn't happen much if you wait for the PC to fully boot before turning the headset on. It's great for grabbing clips though and has a lot of EQ settings.

I personally just got the Audeze Maxwell, which are essentially a hybrid between gaming and audiophile. They’re closed backs, but they still sound great. I agree that it’s important to take a step away from these overpriced “gaming” headsets that are really just garbage. My previous headset was the Arctis Pro Wireless, which was inferior in every regard, and it was *still* more expensive than the Maxwell’s. Really goes to show how poisonous gaming branding is.
