Silicone tips seal the ear canal, blocking outside sound passively and helping bass sound fuller; if the tip does not seal, noise cancelling and bass both weaken.

Driver and microphones—1-way dynamic driver; 3 microphones per earbud Samsung
Connectivity and codecs—Bluetooth 5.4, Auto Switch; SSC (Samsung Seamless Codec), AAC, SBC

SSC is Samsung’s own codec for higher-quality audio with Galaxy devices; other phones use AAC or SBC. Auto Switch moves the connection automatically between Galaxy devices on the same account.

Samsung
Battery—Earbud 53 mAh, case 515 mAh (typical); music: 6 h / 24 h total with ANC on, 8.5 h / 30 h total with ANC off; talk: 4 h / 18 h total

Samsung’s times come from internal tests with pre-production units and default settings; rated capacity is 50 mAh per earbud and 500 mAh for the case. Real runtime depends on volume, codec and battery age.

Samsung
Sensors and controls—Proximity, Hall, touch and pressure sensors; pinch/swipe controls on the stem Samsung
Water resistance—IP54 (earbuds only)

IP54 means limited dust protection and resistance to splashing water from any direction; it is not suitable for submersion. The charging case is not protected.

Samsung
Compatibility—Android 11 or later with more than 1.5 GB of RAM

Samsung notes some features may be unavailable on non-Samsung devices. Equaliser, ANC settings and AI features are managed in the Galaxy Wearable app or One UI settings.
