Overview

The Apple AirPods 4 refine Apple's iconic open-ear wireless headphone formula. Positioned between basic budget earbuds and the flagship silicone-tipped AirPods Pro, this generation introduces a choice between a standard entry tier and an upgraded version featuring Active Noise Cancellation (ANC). Powered by the H2 chip, the AirPods 4 bring advanced computational audio, improved voice isolation, and personalized Spatial Audio into a streamlined form factor.

From a daily usage standpoint, these earbuds deliver one of the most frictionless experiences available within the Apple ecosystem. However, like their predecessors, the primary tradeoff lies in structural serviceability—a factor that every long-term owner must consider.

Design and build

Apple subtly reshaped the earbud stems and acoustic outlets on the AirPods 4 using extensive ear-mapping data. The result is a fit that feels slightly more secure for a wider array of ear shapes without forcing a deep insertion into the ear canal. For users who find silicone ear tips uncomfortable or irritating over long periods, this open geometry is a welcome relief.

Both the earbuds and the charging case carry an IP54 rating for dust, sweat, and water resistance, expanding their usability during workouts or mild rain. The charging case itself has been scaled down to a remarkably compact size and now features a universal USB-C port, dropping the legacy Lightning connector. On the ANC variant, the case also embeds a small speaker for Find My alerts and supports wireless charging via Apple Watch chargers and Qi-certified pads.

Everyday performance

Acoustically, the AirPods 4 are a notable step up from older non-Pro models. Low-end reproduction is tighter and warmer, while vocal clarity in podcasts and phone calls remains consistently crisp. The H2 chip manages dynamic EQ on the fly, compensating well for the inherent lack of an airtight acoustic seal.

On models equipped with Active Noise Cancellation, the engineering is impressive. While an open-ear design can never physically block ambient noise as effectively as a rubber-tipped fit, the computational ANC successfully tones down low-frequency engine rumbles, air conditioner hums, and transit drone. Hands-free Siri gestures and head-tracking Spatial Audio work smoothly, making daily interaction feel intuitive.

Battery, durability, and longevity

With non-ANC listening, the earbuds provide around 5 hours of continuous playback on a single charge, which drops closer to 4 hours with active noise suppression engaged. The pocketable charging case supplies up to 30 hours of total listening time under ideal conditions.

Where longevity hits a wall is battery health over time. Microscopic lithium-ion coin cells inside miniature wireless earbuds undergo frequent charge cycles. After 18 to 24 months of routine daily use, owners usually notice reduced runtime per charge. Because the plastic enclosures are bonded shut with heavy adhesive, opening the earbud or replacing an aging cell without destroying the outer shell is impossible. From an internal hardware standpoint, the AirPods 4 earn a minimal repairability score, essentially rendering them a consumable device over a 2 to 3-year cycle.

Common issues owners hit

While hardware failures are relatively rare early in ownership, standard wear patterns develop as the months add up:

• Audio Imbalance & Reduced Output: Earwax and skin oils accumulate on the microscopic speaker mesh grids, leading to muffled sound or a uneven volume balance between the left and right sides.
• Microphone Muting during Calls: Dust build-up inside the exterior beamforming mic vents can degrade call quality or confuse the H2 chip's noise-suppression algorithms.
• Battery Drain Differences: One earbud may drain significantly faster than the other, often caused by one bud acting as the primary microphone or uneven cell degradation.
• Find My Tracking Disconnects: Bluetooth pairing blips or firmware desynchronization can occasionally require a manual case reset.

If you run into persistent audio drops or connectivity glitches, checking the device page or our troubleshooting index on LML Repair can help isolate software bugs from hardware wear.

Who it's for

The Apple AirPods 4 are ideally suited for iPhone and Mac users who want top-tier convenience, clear call quality, and decent noise control without the plugged-ear feeling of silicone tips. If you prioritize daily convenience and smooth multi-device switching over repairable hardware, they are a stellar fit.

Bottom line

The Apple AirPods 4 are exceptional open-fit earbuds that push audio quality and noise cancellation further than expected for an open design. They excel in everyday comfort and ecosystem integration, but their glued, non-repairable construction means their operational lifespan is defined by the natural wear of their tiny internal batteries.
