Samsung says automatic personalized beamforming and a DNN separate speech from background noise.

Sennheiser
Driver and frequency response—42 mm dynamic driver; 6 Hz–22 kHz; 106 dB SPL (1 kHz / 0 dB FS)

Sennheiser
Impedance—Active 470 Ω, passive 60 Ω Sennheiser
Noise cancelling and microphones—Adaptive hybrid ANC; 4 microphones in total (2 per side, MEMS, beamforming; 50 Hz–10 kHz); anti-wind mode; transparency mode

Hybrid ANC uses both outer and inner microphones; adaptive mode changes the level of cancellation to match ambient noise.

Sennheiser
Bluetooth and codecs—Bluetooth 5.2, Class 1; A2DP, AVRCP, HFP; SBC, AAC, aptX and aptX Adaptive

aptX Adaptive works only with Android phones that support it; iPhones use AAC. Multipoint connections are managed in the app.

Sennheiser

Sennheiser says the 60 hours was measured with an iPhone at medium volume; higher volume and aptX Adaptive can shorten it.

Sennheiser
Wired use—Hi-res digital audio over USB-C; 3.5 mm / 2.5 mm analogue cable

When listening over USB-C, the headphones decode digital audio internally; the analogue cable works even with a flat battery.
