These over-ear, noise-reducing headphones produce a surround-sound 7.1 effect that is the equivalent of a typical 8-channel speaker setup. They are designed for long-term comfort and all-day wear, with an adjustable headband and soft-cushioned, over-ear cups. The design reduces background noise for a fully immersed experience and also enhances bass, while a top quality 50 mm speaker punches out true, high-fidelity sound with great audio detail.
