About This 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/speakers to keep dialogue clear; if it can’t sit near the sound source, use the controller’s left/right volume to balance speech for each ear. In Hearing Mode, return to face-to-face conversation. To fine-tune without extra tweaking 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/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 for public places and daily conversation: To build voices to cut through background noise. The OK Biotech split design separates the earphones from a portable controller, allowing you to treat the controller as an “ear extension”. For distance conversations, simply place the controller near the talker or sound source for cleaner 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 avoid pocket friction noise. Position the controller near a TV screen for more transparent dialogue, or fine-tune the left/right volume on the controller to balance speech for each ear.
