The Radius BL04 (U10P-S) is a specific type of headset connection cable (bottom lead) designed to link a Radius Quick Disconnect (QD) headset top to various desk phones, featuring a reversed wiring for compatibility with phones (like many Grandstream, Snom, Yealink) that have an RJ9/RJ11 headset jack, allowing quick call disconnection from the phone's handset port. It's a direct-connect cable, often replacing Plantronics U10P-S adapters, providing a simple QD-to-phone connection without an amplifier. Show more
