The A10 cable can be used with any H-series headset to connect directly into a phone's headset port. When the A10 cable is used, no other amplifier is required. Easily connect any Plantronics H-series headset to a headset-ready phone via the headset port with A10. Recommended for use in an environment with a mix of M22 amplifiers and direct connect solutions. Allows H tops to be used in amplified and direct connect systems – and reduces the risk that the wrong headset will be connected (Polaris on an M22 or H top on a U10P) which would result in degraded transmit.
