3. Fitting the Earbuds

Mono Mode and Twin Stereo Mode
The Redzeo MDots earbuds offer flexible listening options:

- Twin Stereo Mode: Use both earbuds simultaneously for an immersive true wireless stereo sound experience. This mode is ideal for enjoying music or blocking out surrounding noise.

Sound Quality
The MDots wireless earbuds deliver well-balanced sound with stereo bass. For the best audio experience, ensure you have selected the optimal eartips for a proper seal, which enhances bass and overall sound clarity.

Maintenance
Cleaning
Regular cleaning helps maintain sound quality and hygiene.
- Use a soft, dry, lint-free cloth to wipe the earbuds and charging case.
- For eartips, remove them from the earbuds and clean with a mild soap solution if necessary, then rinse thoroughly and dry completely before reattaching.
- Gently remove any earwax or debris from the earbud mesh using a small, soft brush or cotton swab.
Storage
Always store the earbuds in their charging case when not in use to protect them and keep them charged.
Water Resistance (IPX6)
The Redzeo MDots earbuds feature an IPX6 waterproof nano-coating design, making them resistant to sweat, water splashes, and rain. They are suitable for strenuous exercise and all-weather conditions.
