Yeah, C, I will be using the Sordins for audio only because I want the stealthiness and fidelity of like, a headset...but, I want the 100% situational awareness that's only obtainable in a headset if you use Sordins. That and it's very MF. Dave, I run my radio so it's accessible to me at all times, so, I can use the volume knob on the radio. Also, using the Sordins means that I can easily switch back over to the speaker mic in case I'm with people with not as good comms who need to hear what I'm hearing.
