FANSAISI X19 Bone Conduction Hearing Aid & Bluetooth Earphones User Manual

1. Introduction

Thank you for choosing the FANSAISI X19 Bone Conduction Hearing Aid & Bluetooth Earphones. This innovative device combines the functionality of a hearing aid with the convenience of Bluetooth earphones, utilizing bone conduction technology for a comfortable and open-ear listening experience. It is designed to assist with daily conversations and provide wireless audio playback without blocking your ear canals.

2. Product Overview & Key Features

The FANSAISI X19 offers a unique dual-mode operation, automatically switching between hearing aid and Bluetooth modes based on your activity. Its lightweight and waterproof design ensures comfort and durability for various uses.

2.1 Bone Conduction Technology

This device transmits sound through bone vibrations directly to your inner ear, bypassing the eardrum. This method prevents ear pain and allows you to remain aware of your surroundings while listening to audio or enhancing conversations. It is particularly recommended for individuals who find traditional in-ear devices uncomfortable or experience a sense of blockage.

2.2 Dual Functionality: Hearing Aid & Bluetooth Earphones

The X19 functions as both a hearing aid to amplify ambient sounds and Bluetooth earphones for music and calls. When powered on, it defaults to hearing aid mode. If a mobile phone operation is detected or sound is played, it automatically switches to Bluetooth mode. After approximately 3-5 seconds of no phone operation or sound, it reverts to hearing aid mode.

2.3 Noise Reduction for Clearer Conversations

Equipped with a noise reduction collection microphone, the device suppresses environmental noise and emphasizes frequency bands corresponding to human voices, making conversations easier to hear. You can switch between strong and weak noise reduction modes by pressing the power key.

2.4 Lightweight Design & IPX5 Waterproofing

Weighing approximately 29g, the X19 is designed for extended wear without discomfort. Its open-ear design allows for use even with glasses. The IPX5 waterproof rating means it can withstand sweat during exercise or light rain, offering worry-free use in various conditions.

2.5 Long Battery Life

Equipped with a 250mAH polymer lithium battery, the device fully charges in 2 hours and provides up to 15 hours of operating time, ensuring it meets your daily needs without frequent recharging.
