5 Pack of Pryme BTH-550-MAX Wireless Speaker Microphone with ROTARY Volume Control and Built-in Wireless PTT Wireless Speaker Microphone with Rotary Volume Control. 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. The new PrymeMAX™ version works on phones, tablets (iOS and Android), plus many two-way radios that have built-in Bluetooth including ICOM, Kenwood, EFJ and BK (Except BKR series).
