Release year20252024
Design and fitSealed in-ear design, silicone tips (three sizes), stem body; earbud 18.0 × 21.1 × 33.8 mm, 5 g (with M tip); case 58.9 × 48.7 × 24.4 mm, 41.8 g

Silicone tips seal the ear canal, blocking outside sound passively and helping bass sound fuller; if the tip does not seal, noise cancelling and bass both weaken.

Driver and microphones1-way dynamic driver; 3 microphones per earbud Samsung—
Noise controlActive noise cancelling (ANC) and ambient sound

ANC uses microphones to detect outside sound and plays inverted sound to reduce steady noise such as engines and hum. Ambient sound lets you hear your surroundings without removing the earbuds. Adaptive ANC that adjusts to the environment is not listed for this model.

Samsung		Vent system for pressure equalisation; active noise cancellation only on the separately sold ANC model

At launch Apple offered two distinct models: AirPods 4 and AirPods 4 with Active Noise Cancellation. This model has an open design that does not seal the ear canal.

Samsung’s times come from internal tests with pre-production units and default settings; rated capacity is 50 mAh per earbud and 500 mAh for the case. Real runtime depends on volume, codec and battery age.

Samsung		Up to 5 hours listening per charge; up to 30 hours total with the case; 5 minutes in the case ≈ 1 hour listening

Apple measured these figures at 50% volume with Spatial Audio off.

H2 enables Voice Isolation, Siri Interactions with head gestures and Personalised Spatial Audio.

Apple
Microphones and sensors—Dual beamforming microphones, inward‑facing microphone, optical in‑ear sensor, motion- and speech-detecting accelerometers, force sensor

The speech-detecting accelerometer helps detect when you are speaking; the optical sensor resumes playback when the bud is put in.

Durability—IP54 dust, sweat and water resistance (earbuds and case)

According to Apple this is for non-water sports and exercise; resistance is not permanent and may decrease with wear. Do not charge when wet.
