Incredible Sound 50mm driver units that reproduce crystal clear sounds in high, low and mid-range tones create an incredible audio experience. The Dota 2 Headset is powered by an advanced built-in sound card that features customizable equalizer settings and upgradable firmware for future expanded audio and illumination settings. Personalize. Equalize. Let’s face it, the way you hear the game is unique to the tones your hearing can pick up, and probably completely different than the next gamer, which is why SteelSeries provides Dota 2 Headset users the ability to adjust, personalize and save all audio and equalizer settings so you hear the game the way you want to. This feature allows you to save up to 8 settings for each of your game profiles. Dota Red Illumination 16 Super Bright LEDs create a beautiful, even illumination around each ear cup capable of functioning in 6 different modes. Through the SteelSeries Engine, users can customize illumination in pulse (fast and slow), intensity (low and high), and even a sound activated mode. Of course, in true SteelSeries fashion, you can turn off the lights and still enjoy the amazing quality and audio features of this advanced headset. Smart Noise-Canceling, Retractable Mic The Dota 2 Headset features an active noise-cancelling, “smart” microphone that allows your team to hear you above whatever is happening in the area around you – appliances, dogs barking, whining spouses, and more. It also features a retractable microphone system. Pull it out when you need it. Hide it in the left earcup when you don’t.
