Release year20242024
DesignOpen-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 microphones11 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 cancellingActive 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 qualityUHQ 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 codecsBluetooth 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 sensorsPinch 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 lifeMusic: 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).

Samsung		—
Water resistanceIP57 (earbuds only)

IP57 means dust-protected and resistant to brief immersion; the charging case is not covered.

Samsung		—
CompatibilityAndroid 10 or later with more than 1.5 GB of memory

Some features are not available on non-Samsung devices.

Type—True wireless stereo in-ear earbuds; ear-canal fit with ear fins

The box includes four sets of ear tips (XS/S/M/L) and three sets of ear fins (S/M/L).

Sennheiser
Driver—TrueResponse dynamic, 7 mm; 5 Hz–21 kHz; 107 dB SPL (1 kHz / 1 mW)

According to Sennheiser, audio resolution up to 24-bit/96 kHz is supported with a compatible source.

Sennheiser
Noise cancellation—Hybrid ANC, adaptive to surroundings; Transparency Mode

Adaptive mode sets the cancellation level automatically for the surrounding noise; Transparency Mode lets outside sound in without removing the earbuds.

Sennheiser
Bluetooth and codecs—Bluetooth 5.4 (Classic and LE Audio); SBC, AAC, aptX, aptX Adaptive/Lossless, LC3; A2DP, AVRCP, HFP, TMAP, PBP

aptX Lossless needs a Snapdragon Sound phone that supports it; an iPhone uses AAC. According to Sennheiser, Auracast broadcast listening only arrives through a firmware update. Multipoint lets it switch between two devices.

Sennheiser
Microphones—3 MEMS microphones per earbud (6 in total), beamforming noise reduction; 100 Hz–10 kHz Sennheiser
Battery—Up to 7.5 hours per charge (ANC off) / up to 7 hours (ANC on); up to 30 hours total with the case; lithium-ion, 75 mAh per earbud, 820 mAh case

Times were measured with an iPhone at medium volume (85 dB). According to Sennheiser, 8 minutes of charging gives about 1 hour of playback; the battery protect mode in the app slows charging and slightly lowers maximum capacity to extend battery lifespan.

Sennheiser
Charging—USB-C socket on the case (5 V, 1,000 mA max) and Qi wireless charging

A USB-C cable is in the box; there is no adapter.

Sennheiser
Durability—IP54 dust and splash resistance (earbuds only)

The charging case is not covered by the IP rating.
