Buy the Razer BlackShark V2 X Gaming Headset.

It nails the two things a gaming headset actually has to do, sound clear and last, better than either rival manages.

What was compared

1. Your team hears you, not your room
The BlackShark's HyperClear cardioid mic is built to isolate voice, while the Logitech H390's boom mic is tuned for office calls and the Stealth 600's flip mic gets mixed reviews on clarity. In a real match, that gap is the difference between callouts landing and getting lost.
2. Still comfortable three hours in
At 240g with memory foam cushions, the BlackShark disappears on your head during long sessions. The H390 is on-ear and presses into your ears over time, and the Stealth 600's wireless internals add bulk the Razer skips entirely.
3. Won't quit on you in a few months
Owner reports on the Stealth 600 describe cracked plastic and random disconnects starting within 4 to 6 months of normal use. A wired headset like the BlackShark has no battery to degrade and no wireless link to drop, which is exactly why it holds up.
4. Yes, wireless is real. Here is why it loses.
The Stealth 600's 80-hour battery and cordless freedom genuinely matter if you game from a couch across the room. Unless that is your exact setup, a cord at a desk or console costs you nothing, and it removes the exact failure point that keeps showing up in Stealth 600 complaints.
5. One cable, every console you own
Plug the BlackShark's 3.5mm jack into Xbox, PS5, PC or Switch and it just works, no pairing, no charging, no drivers. The H390 is USB-A only and locked to computers, while the Stealth 600 needs charging and mode-switching to move between devices.
