The Galaxy T1 earbuds popped up in an FCC document, receiving US certification approval on November 4. The model number of the device is listed as SM-R545 and codenamed T1, but most importantly, the FCC documents give us a peek at the next Samsung audio release.
The FCC documents cover both the left and right earbuds separately, and they carry rather long and uninspiring nomenclature — ZCASMR545L and ZCASMR545R. This is the first appearance of this device on US certification soil, and even though there aren't many details spec-wise, we're still learning some cool things about the Galaxy T1 earbuds.

Galaxy T1 earbuds specs and features

FCC certification documents offer just a handful of hints about the specs and features of the device in question. From the recent listing, we get "T1 Cable" and "T1 Project" labels, confirming the name of the earbuds.
Previous reports mentioned the name Earbud Fit Test, along with customizable touch controls.
There's a charging cradle with the designation EP-QR545, and the buds ran firmware R545XXU0AZH1 during the FCC test. This already tells us that we're dealing with Bluetooth-enabled earbuds, and during the test, the prototype achieved 14.5 meters of wireless range in a lab environment.

We also know the battery and charging voltage — the Galaxy T1 battery is rated at 3.85V and charges at 5V from the aforementioned charging cradle. Earlier leaks suggested 63mAh batteries in each earbud, and a 595mAh one inside the charging case.
Galaxy T1 design and look

The most interesting part of the FCC filing is actually a picture of the device undergoing lab tests. Of course, the test device is most likely vastly different from the production model, but still, we have something to look at.
The earpiece is shown with a hook design wrapping around and behind the ear of the test dummy. This design reminds me of the Powerbeats Pro and the Bose QuietComfort Ultra models.
This wraparound hook popped up in previous reports as well, and it makes a lot of sense, since it's one of the most secure ways to keep the buds in place during intense workouts. The FCC documents also contain a schematics of the charging case.
It looks sleek but there are no dimensions and depth to the drawing so we can't tell how big this thing actually is. It features sort of a flat design, but that's all I can discern from the technical drawing.
Galaxy T1 earbuds launch date and pricing

The recent FCC certification approval points toward a release window in the near future. The Galaxy T1 already appeared in certification documents in China, South Korea, and Indonesia, and the US addition hints that Samsung is aiming for a multi-market launch.
Of course, all this is pure speculation at the moment, and we don't have any idea when these buds will launch and how much they will cost.
One possible scenario is an early 2027 debut alongside the upcoming Galaxy S27 lineup. As for the price, the recently announced open-ear Galaxy Buds On start at $229, so we should expect a similar price tag for the sporty version.
