PRYME BTH-550-MAX Bluetooth Microphone
The BTH-550 is a compact and lightweight wireless speaker microphone with a 3.5mm earphone jack, more portable than the
Pryme BTH-600-MAX, yet equally weather-resistant. It stands out with its ROTARY VOLUME CONTROL, which is particularly user-friendly, especially for those wearing gloves. This device offers impressive battery life, with over 40 hours of talk time (typically up to 80 hours) and more than 30 days of standby, making it a reliable choice for extended use.
The latest PrymeMAX™ version enhances compatibility, working seamlessly with phones and tablets (both iOS and Android) as well as numerous two-way radios with built-in Bluetooth, such as ICOM, Kenwood, EFJ, and BK (
excluding the BKR series). It’s also fully compatible with all PrymeBLU radio adapters, including the newer V2 models. According to additional details found online, PrymeMAX is praised for its versatility in professional and industrial settings, often used by security teams, event staff, and outdoor workers due to its durability and clear audio.
Other features include a waterproof front-facing speaker, a directional noise-canceling microphone for clearer communication in noisy environments, and a robust 360° swivel clothing/belt clip for easy attachment. The device also has conveniently placed pairing and low-battery indicator lights on top, simplifying operation.
