Question about Midland Security headset

The security headset (manufacturer Midland, product ID C732.06) is not compatible with the Midland G9 Pro walkie-talkie. This is confirmed by user reviews that explicitly state that the headset does not work with the G9 Pro. In addition, the G9 Pro uses a 2-pin standard Icom (S) connector for accessories, while the C732.06 headset has a different connector that is more compatible with older Midland models.
