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.

Durability—IP54 dust and splash resistance (earbuds only)

The charging case is not covered by the IP rating.
