This does use 2.4ghz to broadcast audio through. So it's possible that it could cause some issues. The best thing to do would be to change the channel your router is using. Most routers will allow you to surf into their IP address (usually something like 192.168.1.1) and under the wireless settings you'll notice most routers default to a single selected channel rather than automatically choosing the best one for your specific needs. If you're in an apartment or condo, your neighbors will all have microwaves, routers, Bluetooth devices, etc that all make use of 2.4ghz and most people don't bother changing the default settings to avoid that crowded frequencies busiest channels. For more info on how to do this with your specific router, check with your ISP if they provided it, upgrade to a dual band router that supports 5ghz, or check your router's user manual online.

Technically, the last generation of consoles didn't output sound directly to USB without special assistance from supported software, so the answer, technically is no....however, there are plenty of workarounds, especially if you have a computer nearby the console that you can route your sound through. It may sound complicated, but it's really not. You can run the sound out of an Xbox or PS3 into your sound card, then back out to this headset. You retain all of the capabilities except some of the 7.1 surround (unless you maintain 7.1 digital out of your console and into the PC). If you can run optical (toslink) out from the console into your PC's sound card, you will get 5.1 surround. So there are definitely ways around the technical answer of 'no'. Also, PS4 compatibility is a Yes, but with the exception of surround sound. You will get stereo channels only when using this headset with a PS4 in console mode. Best of luck!

No, this uses a proprietary USB dongle which utilizes a high throughput 2.4ghz channel similar to wifi.
