Thankyou.
Provided your headsets have mics and have a single plug for both connections look to helicopters for their use as most helicopters use a single connector. Not familiar with the AM671 spec but for comparison with single plugs here look at the U-93A or U-174 connector/plug used in military/civilian helicopters. Regardless of the connector, be sure to check the headset impedance, mic type, etc before plugging them into a live system.
