BT20 Pro Wireless Bluetooth Headset Module with Replaceable Plug-in Connector

This BT20 Pro upgrade module is a replacement part for compatible ear hook headsets, giving you a way to restore wireless audio without buying a complete new set. It uses a Jerry chip and supports Bluetooth audio, call function and voice control, with a stated transmission range of 15 metres and more than 8 hours of battery life. The waterproof plastic module attaches via an ear hook design and is available in four connector variants: BT20 Pro S, BT20 Pro 0.75, BT20 Pro 0.78 and BT20 Pro MMCX. Each pack contains one pair of modules.

Features and Construction

The module is built around a plastic ear hook housing that keeps the unit light enough to wear during calls and everyday listening. The Jerry chip manages the wireless connection, while the waterproof construction adds protection for use in damp conditions.

Material and Build

The body is made from plastic, which keeps the module lightweight and suitable for attachment to an ear hook. The plug-in connector is replaceable, so you can choose the variant that matches your existing headset rather than replacing the whole unit. The waterproof design is stated for the module, making it a practical choice for users who need a headset part that can handle moisture during daily use.

Size and Practical Fit

The module uses an ear hook design and is available in BT20 Pro S, BT20 Pro 0.75, BT20 Pro 0.78 and BT20 Pro MMCX connector types. No physical dimensions are provided in the source information, so fit depends on selecting the correct variant for your headset. The stated 15 metre transmission range gives reasonable freedom to move away from a paired device in open spaces.

Uses and Placement

This module suits users who already own a compatible BT20 Pro ear hook headset and need a replacement or a different connector type. It supports wireless calls and voice control, making it useful for hands-free communication at home, in the office or outdoors.

Event or Professional Use

For work calls, online meetings or hands-free phone use, the module provides wireless audio and voice control access. The stated battery life of more than 8 hours can cover a typical working day, depending on volume and usage. The waterproof construction is helpful for users who move between indoor and outdoor environments where light rain or sweat may be present.

Everyday Home Use

At home, the module can be used for listening to audio, taking calls or controlling playback by voice where supported by the paired device. The ear hook design keeps the module in place during movement. Because it is a replaceable plug-in part, you can keep a spare pair or switch connector types without changing your main headset.

Benefits and Buying Value

The main value of this product is its role as a replaceable upgrade module rather than a complete headset. It lets you address a faulty or unsuitable connector while keeping the rest of your setup. The waterproof build and stated battery life support regular use.

Reuse and Low Maintenance

By replacing only the module, you avoid discarding a headset that may still be otherwise usable. The plastic housing can be wiped clean with a dry cloth, and the waterproof construction helps protect against moisture. No specialist maintenance instructions are provided, so keep the connector area clean and dry between uses. Charging and storage details beyond the stated battery life are not specified.

Why Choose This Product

Choose this module if you need a specific BT20 Pro connector variant and want wireless Bluetooth audio with call and voice control functions. The stated 15 metre range and more than 8 hours of battery life are the key practical specifications. Available in S, 0.75, 0.78 and MMCX versions, it offers a targeted replacement option rather than a one-size-fits-all part. Each pack includes one pair of modules.
