At first glance $250 seems a bit on the pricey side for a SteelSeries gaming headset, however it also ships with a seperate DAC which explains the pricing.  The build of the Arctis Pro will be familiar to anyone who has seen the wireless Arctis 7, inside are a pair of 40m neodymium drivers with a 20-40,000 Hz frequency response.  The DAC is an ESS Sabre 9018Q2C DAC and offers optical, USB and a 3.5mm line out, the second 3.5mm port labeled mobile is an input so you can play music on the run.  The one thing it does lack is a way to connect to other gaming headests, which may be a deal breaker for many.  TechPowerUp gave it very high marks for audio playback, calling it the best they've heard yet this year.

"The $250 / €270 Arctis Pro + GameDAC is SteelSeries' new flagship gaming audio system. It consists of an amazing gaming headset based on an improved iteration of the Arctis 3, 5, and 7 and the GameDAC, a high-quality external USB sound card equipped with the ESS Sabre 9018Q2C DAC chip and a host of advanced features, fully usable and configurable without any drivers."
