"Headphones are great for gaming and watching movies when you need to be quiet. I’ve got small children and I like to watch movies and  play games at night time, late at night, and my kids need to sleep. What I have for review today very much helps me accomplish that and more of course. I’ve got the ARCTIC P531 5.1 Headset for gamers for review today, these feature a USB connection and not actual audio connections which I think makes life easier and. Having the USB connection allows you to just plug it into a front port, but if you don’t have a motherboard equipped with surround sound it doesn’t mater as the P531 headset has a built-in digital sound processor. This headset is for gamers so as you might expect it has a microphone and a lot of padding for comfort so they can be worn for long periods of time.  "
