Frequently Asked Questions

Q: Is this Bluetooth 5.3 earbud compatible with both Android and iPhone?

A: Yes! The Bluetooth 5.3 protocol offers broad universal compatibility — it pairs seamlessly with iOS and Android smartphones, tablets, Windows PCs, and most other Bluetooth-enabled devices. Simply search for "M5" in your device's Bluetooth settings to connect.

Q: Can I use two of these earbuds together for stereo sound?

A: Absolutely. Each unit operates as a single mono earbud by default, which is ideal for hands-free calls while staying aware of your surroundings. Purchasing two units and pairing them together enables true wireless stereo (TWS) playback for full HiFi audio.

Q: How waterproof is this earbud — can I use it during workouts?

A: The earbud carries an IPX5 waterproof rating, meaning it is fully protected against sweat and water splashes from any direction. It is well-suited for gym sessions, outdoor runs, and light rain, though it should not be submerged in water.

Q: How do I know when the battery is low?

A: The built-in digital display uses a 1–9 scale to show the current charge level at a glance. When the display shows "9", the earbud is fully charged. As the battery drains, the number decreases so you always know exactly how much listening time remains.
