Turtle Beach Elite Pro Tactical Audio Command (T.A.C.) is a mouthful to say, and by looking at the packaging, it is very much as technical as it sounds, but not as complicated. It is a necessary companion to the Turtle Beach Elite Pro headset, and will enhance any wired headset, but isn’t required. This control unit provides many improves to a standard headset, but gives you total control on the audio you deliver and receive. It also gives great visual feedback via its bright LED lighting system at just a glance regarding how you’re using it. Regardless of what you use it with, the TAC is an expensive add-on that works for your money.
