I don't know what kind of speds are up at Microsoft but this app sucks I only use it so I can talk to my friends that's all wouldn't recommend it disconnects me so often even if I only leave the app for 3 seconds there is horrible echo with the mic if you don't have earbuds I've noticed or a headset honestly just buy a headset trust me the extra 20-30 dollars is worth it so you can just use the normal Xbox party from your console
