Type—Around-ear, closed-back, wireless; active noise cancelling

The ear pads fully surround the ear; Sennheiser cites a lightweight design, padded headband and deep cushioned earpads for long-wear comfort.

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

The frequency range describes measurement limits; the sound you hear is also shaped by the in-app equaliser and sound personalisation.

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
Battery and charging—700 mAh lithium-ion; up to 60 hours with noise cancelling on; full charge in about 2 hours; up to 4 hours from 5 minutes of charging; USB-C 5 V 800 mA

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.

Sennheiser
Controls and app—Touch surface on the right cup; Smart Pause wear detection; Auto On/Off; 5-band equaliser and Sound Personalization in the Smart Control app

Smart Pause stops playback when the headphones are taken off and resumes when they are put back on; Auto On/Off shuts them down to save power when not in use.

Sennheiser
Water resistance—No IP rating listed

With no certification against sweat or rain, care is needed when it gets wet during exercise.
