It's sleek, it's comfortable, and it stays securely in place, even during dance-oriented performances, focusing right in on its source, and capturing the warmth with its wide frequency range. It rejects unwanted sounds and monitor feedback even better than most handhelds. It tolerates sweat, weather, and makeup better than other headsets, and best of all, it's affordable and durable, offering a long life of excellent sound. It comes supplied with wind screen.
