OKB Hearing GV-SA0361 Hearing Amplifier for TV & Conversation | Neckband-Style Bluetooth 5.0, Noise Reduction, 2-in-1 Modes, USB-C Rechargeable

• Dual-mode noise reduction (Standard/Enhanced): One button allows you to switch between Standard and Enhanced freely; press once more to return to regular listening. Avoid Enhanced when full situational awareness is required. For outdoor use, attach the included external microphone to clothing or a bag to reduce friction noise.
• 2-in-1 listening + four presets: Users switch with one button. In TV Mode, place the controller close to the TV or speakers to keep dialogue clearer; if it can’t sit near the sound source, use the controller’s left and right volume to balance sound for each ear. In Hearing Mode, return to face-to-face conversation. To fine-tune without extra adjustments after choosing a mode, pick one of four ready-to-use presets—Quiet indoor chats, Crowded gatherings, Outdoor walks, Device streaming (per user-provided copy). For audio from a phone or tablet, press the controller’s stream or music button to enter or exit music mode.
• Neckband-style portability and quick start: Lightweight, ergonomic neckband earphones in Mirror Chrome rest comfortably on the neck for carry-along use. The controller and earphones are pre-paired at the factory and auto-connect with a “Bluetooth connected” prompt when powered on. Medium ear tips are pre-installed; users can swap to the correct size and wash tips with dish soap and warm water, then dry thoroughly to keep a secure, comfortable seal.
• Speech-focused amplification for public places and daily conversation: Designed to amplify surrounding sound so voices can be heard more clearly in everyday environments. The OK Biotech split design separates the earphones from a portable controller, allowing the controller to work like an “ear extension”. For distance conversations, place the controller near the talker or sound source for clearer pickup. In meetings, set it at the centre of the table to capture group discussion. For outdoor use, attach the included external mic to clothing or a bag to reduce friction noise. You can also place the controller near a TV or adjust left/right volume to balance sound for each ear.
