The RECON EH-1399sC is a surveillance-style, listen-only acoustic tube earphone that allows you to privately and comfortably monitor incoming communications. This model is built specially for the BTH-300 and BTH-550 using a 4 Conductor / 3.5mm plug instead of the more typical 2 conductor plug. The acoustic tube is easily removeable using our NEW twist connector, which makes it easier for multiple users to share the same earphone using separate ear tubes.
