G733 LIGHTSPEED Wireless Gaming Headset
You can’t use these with Iphone or any phone but they will work on your computer. They’re not the greatest headset for music if you’re trying to do other things with them I recommend looking at other options these are good mid range gaming only headset nothing else.
No they are not . Nintendo Switch requires wired headphones as it does not have Bluetooth abilities that wireless headphones use to connect.
