Samsung Galaxy T1 sports earbuds (SM-R545) pass FCC ahead of US launch

Samsung's mysterious workout earbuds have cleared US certification. Android Authority spotted that the unannounced Galaxy T1 — model SM-R545 — received FCC approval on November 4, 2026, after earlier stops in China, South Korea and Indonesia.

What the FCC filing reveals

• Each earbud is certified separately, under FCC IDs ZCASMR545L and ZCASMR545R.
• References to a "T1 Cable" and "T1 Project" confirm the leaked codename; the charging cradle is model EP-QR545.
• Testing used prototype hardware on firmware R545XXU0AZH1, with a Bluetooth range of over 14.5 metres in the lab.
• The documents list a 3.85 V battery and 5 V charging input from the cradle, plus a technical drawing of the case.

Samsung has kept product photos and the user manual confidential for now.

What's still rumour

Earlier leaks point to an ear-hook design to keep the buds in place during workouts, an Earbud Fit Test, customisable touch controls, roughly 63 mAh cells per bud and a 595 mAh case. None of that is officially announced, and Samsung hasn't confirmed a retail name, price or release date. A debut alongside the Galaxy S27 in early 2027 is possible but speculative.
