Using high quality UHF transmission between the headset and receiver, this kit provides you with great quality audio reproduction without any messy wiring. The receiver provides a simple 3.5mm AUX connection for a Hi-Fi or PA system, with multiple adaptors for maximum compatibility. The headset itself has no external pack - everything is contained right there within the headset itself. Fully rechargeable, you’ll get 4-8 hours of talk time from a 2-3 hour charge. If you prefer to hold the microphone, it’s easily detached from the head bracket for that purpose as well. Simple to setup and easy to use for a variety of applications. Includes 2-Way USB charging cable, 3.5mm plug to 3.5mm plug adaptor and 6.5mm plug to 3.5mm socket adaptor.
