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.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use two of these earbuds together for stereo sound?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: How waterproof is this earbud — can I use it during workouts?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I know when the battery is low?\u003c\/h4\u003e\n\u003cp\u003eA: The built-in digital display uses a 1–9 scale to show the current charge level at a glance.
