Apple AirPods 4 Review: A Strong Contender for Comfort-Focused Users

Alongside the iPhone 16 series, Apple introduced the AirPods 4, available in two variants: a standard model and one with active noise cancellation (ANC). Unlike the AirPods Pro 2, the AirPods 4 feature a semi in-ear design that eliminates the need for silicone tips, making them a compelling option for users who dislike the in-ear fit.

The AirPods 4 weigh just 4.3 grams per earbud and boast an IP54 rating for dust and water resistance on both the earbuds and charging case. They connect via Bluetooth 5.3 and utilize Apple's custom high-excursion driver and high dynamic range amplifier. The ANC version includes dual beamforming microphones, a built-in speaker in the charging case, and support for wireless charging, features absent in the standard model.

In terms of comfort, the AirPods 4 shine. The redesigned speaker unit ensures a secure fit, though the AirPods Pro 2 still edge out slightly in fit quality. The charging case is notably compact and lightweight, though it lacks the U1 ultra wideband chip and MagSafe compatibility found in the AirPods Pro case.

Controls on the AirPods 4 are handled via a force sensor on each earbud, but notably, volume control is missing, requiring users to adjust volume through their phone or Siri. The device also uses an optical in-ear sensor instead of a skin sensor for automatically pausing music when removed, which proves less reliable than the AirPods Pro's system.

Audio performance on the AirPods 4 is solid, with rich midrange and pleasant treble, plus surprisingly robust bass for a half in-ear design. However, the earbuds struggle with sub-bass frequencies, delivering a smeared and bloated sound compared to the tighter response of the AirPods Pro 2. Despite this, the AirPods 4 handle detailed tracks well, offering good instrument separation and soundstage.

Active noise cancellation on the AirPods 4 impresses for a half in-ear design, effectively reducing consistent low-frequency noises like office hum or city traffic. While not as potent as the AirPods Pro 2, which benefits from a tighter seal and silicone tips, the AirPods 4's ANC performs better than Samsung's Galaxy Buds 3 in similar testing. Transparency mode and Conversation Awareness function well, though ambient noise is slightly amplified compared to the AirPods Pro.

Call quality is strong, with effective voice isolation even in windy conditions. However, battery life is a weak point, with approximately 4 hours of playback with ANC enabled, though the case provides up to 20 hours of additional listening time.

In conclusion, the AirPods 4 are an excellent choice for those seeking comfort and ANC without the in-ear fit of the AirPods Pro 2. While it lags behind in sound quality, battery life, and certain features, its comfort and effective noise cancellation make it a worthy alternative for the right user.
