Software 10.12.128 September 2026: LE Audio beta on compatible Android/Windows devices and improved USB calls Bose—
Design—Open-type stem earbuds without silicone tips; silver and white

The open design does not seal the ear canal, so it avoids a pressure feeling over long use but isolates less than tipped models. Fit varies with ear shape.

Samsung
Driver and microphones—11 mm dynamic driver (one-way); 3 mics + voice pickup unit (VPU) per earbud

The VPU picks up the wearer’s voice through bone vibration to help separate speech in noisy calls.

Samsung
Noise cancelling—Active noise cancelling (ANC) and ambient sound mode

ANC measures outside sound with microphones and produces an opposite wave to reduce steady hum; in an open design the effect is more limited than in sealed earbuds.

Samsung
Sound quality—UHQ 24-bit/96 kHz, 24-bit Hi-Fi, 360 Audio with Direct Multi-Channel

UHQ (24-bit/96 kHz) only works on certain Galaxy phones and tablets with One UI 6.1.1 or later (S24, S23, Z Fold6/Flip6, Z Fold5/Flip5, Tab S9 series); 24-bit Hi-Fi needs One UI 4.0 or later. Other devices use AAC or SBC.

Samsung
Connectivity and codecs—Bluetooth 5.4, Auto Switch; SSC HiFi, SSC UHQ, AAC, SBC

Samsung Seamless Codec (SSC) is Samsung’s own codec for higher-resolution wireless audio with Samsung devices. Auto Switch moves the connection between signed-in Galaxy devices automatically.

Samsung
Controls and sensors—Pinch and swipe (Force & Touch) controls; VPU, SWIR, accelerometer, Hall sensor

The SWIR infrared sensor detects whether an earbud is worn; the Hall sensor detects the case opening and closing.

Samsung
Battery life—Music: 5 hours ANC on (24 total with case), 6 hours ANC off (30 total); talk: 3.5 hours ANC on (18 total), 4 hours off (20 total)

These are Samsung’s internal tests with default settings paired to a Galaxy phone. Capacity is 48 mAh per earbud and 515 mAh in the case (typical).

Some features are not available on non-Samsung devices.
