The Avatar Pro ZX500 surrounds you with 7.1 digital audio effects and roof-shaking bass for full game play immersion. But beyond the sound quality is an even more important trait: ease of tuning. Everyone’s got a personal preference and working a deal out with your headphones isn’t always easy. That’s why Armaggeddon’s Avatar Pro ZX500 software with easy-to-use DB sliders make manual equalization a walk in the park. The ZX500 also has volume control access and other useful functions at the tap of a button on the controller so you never have to reach far or interrupt your gameplay to make adjustments.
