Wireless Speaker Microphone with Rotary Volume Control

This is our newest Wireless remote speaker microphone. The BTH-550 is smaller and lighter than our BTH-600, but still just as weather resistant. It has a ROTARY VOLUME CONTROL, which can be much easier to use, especially when wearing gloves. With more than 40-hours of talk time (80-hours typical) and greater than 30-days standby time, the BTH-550 is a real workhorse.

Other features include a waterproof front-facing speaker, directional noise canceling microphone, heavy-duty clothing/belt clip that swivels 360°, and strategically-placed pairing and low-battery warning lights on the top of the microphone the NEW BTH-550 is super easy to use. This industrial-strength unit is multi-functional, featuring a broad-range ROTARY volume control, 3.5mm earphone jack, and rechargeable battery (comes with universal USB wall charger and cable) .  The BTH-550 has a typical operating range of up to 10 meters (depending on smart device range, and enviromental interference).
