I am going on a bike trip in about a month. I have the Midland GXT720 pair. I need a good headset to use while on my bicycle. I am looking at the AVP-H2 and the AVP-H1. Does anyone have experience with either of these headsets? Are there any other ones available that fit my needs? Are their any non Midland brand headsets, since these seem awfully expensive for what they are.
