Does this persist at all times, or only specific games or software?
Have you tried different USB cables?
I have the same problem with my Fusion 700 connected with usb and also left ear cup heats up after some time of using. It presists all the time and only via usb.
We will investigate, so far I cannot discern any noise from my 700 or 500 but more tests will be done. When you say the ear cup heats up, how warm does it get and where is it warm (inside or outside the earcup)?
* After 3 hours, my 700 does not heat up at all, perhaps you need to send your headset in for RMA at an ASUS Service Center.
When you say only via USB, do you mean there won't be noise and heat when connected via Bluetooth?
Yes there are no noise and heating when i using them via BT, so i think it is some problem with USB, i will go the Service Center this week, just decided to let you know that this kind of problem exists.
I can't say concrete temperature but it is felt and inside (warm enough the i can feel it with my ear) the ear cup and outside (i can feel it if i touch it).
Thanks for reporting your issue, I have informed the team so tests can be performed. If issues persist after RMA, let us know.
