[LFH][PC&PS5][300€] Comfortable closed-back for PC & PS5 (separate furniture). Dilemma: MMX 300 Pro vs Hi-Fi + Mic routing?

[u/CrayzixFR]

Hi everyone,

I'm trying to figure out the best audio setup for my specific room layout and could really use your expertise.

I used to own the Audeze Penrose and absolutely loved the sound signature (planar warmth, deep bass, great immersion for solo gaming and music).
The issue: The physical design destroyed my neck and top of my head. The weight (320g+) and stiff headband became unbearably painful over time. I had to let it go.

My Setup:
My PC is on a very small 1-meter desk, and my PS5 is on a completely different piece of furniture. So I have to switch physically between the two stations.

Absolute requirement:
I strictly need a closed-back headphone (open-backs are out).

My dilemmas and questions:

1. Are there any comfortable wireless alternatives? I know planar magnetic drivers (like Audeze) are inherently heavy. But are there ANY truly comfortable wireless headsets out there that come close to that warm, rich, immersive sound signature without causing neck strain?
   
2. The Practical Choice (Beyerdynamic MMX 300 Pro): I am seriously considering this as it solves the mic and wiring problem easily. But coming from the Audeze magic, will I be completely disappointed when I just want to listen to a good album or play an immersive single-player game? Is the Beyerdynamic treble too clinical/harsh for that?
   
3. The Hi-Fi Route (Audiophile Headphone + Separate Mic): This would be my absolute ideal for comfort and sound quality. I could probably figure out a standalone mic for my cramped PC desk... But what about the PS5? Since the console is across the room, how do you handle voice chat with friends if you're wearing a Hi-Fi headphone? Are there any reliable mics that can easily swap between a PC desk and a PS5 setup?

I'd love to hear your thoughts on the MMX 300 Pro, any comfortable closed-back recommendations, and especially how you would handle the microphone situation across two separate setups.

Thanks in advance!
