DriverTrueResponse 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 cancellationHybrid 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 codecsBluetooth 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		—
Microphones3 MEMS microphones per earbud (6 in total), beamforming noise reduction; 100 Hz–10 kHz SennheiserNine microphones in total: eight for noise cancellation; three for voice pickup (two shared with noise cancellation) Apple
BatteryUp 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		Up to 20 hours of listening with Active Noise Cancellation or Transparency on; up to 20 hours of movies with Spatial Audio on; 5 minutes of charge gives about 1.5 hours of listening

Apple’s figures come from pre-production tests with an iPhone 12 Pro Max in November 2020.

Audio technology—Apple-designed dynamic driver; Active Noise Cancellation; Transparency mode; Personalised Spatial Audio with dynamic head tracking; Adaptive EQ

A Personalised Spatial Audio profile is created with an iPhone that has a TrueDepth camera; the feature needs compatible content and apps.

Apple

Sensors—Optical, position and case-detect sensors plus an accelerometer in each cup; gyroscope in the left cup

The position and optical sensors detect when the headphones are put on or taken off to pause and resume playback.

Apple
Controls—Digital Crown (volume, play/pause, calls, track skip, Siri) and noise control button

Turning the Digital Crown changes the volume; the noise control button switches between Active Noise Cancellation and Transparency mode.

Apple
Charging and case—Charging via Lightning; the battery enters an ultra-low-power state in the Smart Case

The box contains the headphones, the Smart Case and a Lightning to USB‑C cable. There is no separate power button; the Smart Case handles power saving.
