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
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

The charging case is not covered by the IP rating.
