Apple AirPods 4 Wireless Earbuds - H2 Chip, 5 Hours of Battery and IP54 Protection

Apple AirPods 4 deliver up to 5 hours of listening time per charge and 30 hours with the USB-C charging case, powered by Apple’s H2 headphone chip and rated IP54 for dust, sweat and water resistance. For everyday iPhone users, the open-ear fit and Personalized Spatial Audio matter most.

Apple AirPods 4 are Apple’s latest open-ear wireless earbuds, pairing a familiar stem design with the newer H2 headphone chip, IP54 dust, sweat and water resistance, and battery life rated at up to 5 hours of listening time from the buds and up to 30 hours with the USB-C charging case.

Design, Fit and Everyday Comfort

Apple AirPods 4 keep the classic white, stemmed earbud look but refine the dimensions slightly for all-day wear. Each AirPods 4 earbud measures about 1.19 inches high, 0.72 inch wide and 0.71 inch deep, and weighs approximately 0.15 ounce, making them light enough to sit in the ear without silicone tips while still feeling secure during daily movement and light exercise. Apple’s tech specs page lists the charging case at 1.82 inches in height, 1.97 inches in width, 0.83 inch in depth and about 1.14 ounces in weight, so it remains pocket-friendly while accommodating a USB-C charging port.

Both the earbuds and the case carry an IP54 rating, which means they are dust resistant and protected against splashes of water and sweat under standard laboratory test conditions. This helps AirPods 4 handle commutes, office use and workouts that involve sweat or light rain, as long as users follow Apple’s cleaning and drying guidance. The open-ear design with a vent system for pressure equalization aims to avoid the “plugged” feeling some people experience with in-ear tips, while the optical in-ear sensor and motion-detecting accelerometer allow the earbuds to detect when they are in use and pause audio when they are removed.

Audio Technology and Controls

Inside Apple AirPods 4, a custom high-excursion Apple driver and high dynamic range amplifier work with Adaptive EQ to tune sound to the shape of the user’s ears. According to the official tech documentation, AirPods 4 support Personalized Spatial Audio with dynamic head tracking, placing sound around the listener for compatible music, movies and games, especially when paired with an iPhone that has a TrueDepth camera to create a personal audio profile. The same Apple resource notes Voice Isolation for clearer calls and several microphones: dual beamforming microphones, an inward-facing microphone, and motion and speech-detecting accelerometers.

The control setup centers on a force sensor on each stem. A single press manages play and pause, answers a call, or mutes and unmutes in supported apps. A double press ends a call or skips forward, while a triple press skips back through tracks. Pressing and holding activates Siri, and AirPods 4 support “Hey Siri” or simply “Siri” voice triggers on compatible devices. The documentation also mentions Siri Interactions, allowing users to nod their head yes or gently shake their head no when Siri asks whether to answer an incoming call, hear a text message, or manage notifications, as long as the AirPods are paired with a device running the latest supported software.

Battery Life, Charging and Connectivity

Battery performance is a key specification for Apple AirPods 4. Apple’s tech specs state that AirPods 4 deliver up to 5 hours of listening time on a single charge, with Spatial Audio turned off and volume set around half according to Apple’s internal test conditions. When paired with the USB-C charging case, the total listening time is rated at up to 30 hours before both buds and case are fully depleted. A quick-charge function allows about 5 minutes in the case to provide around 1 hour of listening time, which is useful for topping up before heading out. These figures are consistent with independent reviews that also quote 5 hours from the earbuds and around 30 hours from the case for the non–noise-canceling version. One detailed review lists 5 hours official bud life, around 30 hours total with the case and confirms Bluetooth 5.3 connectivity.

The charging case uses a USB-C connector, matching newer iPhone models and simplifying cable management. Wireless charging is not part of the standard AirPods 4 package; instead, Apple reserves wireless charging for the separate AirPods 4 model that adds Active Noise Cancellation and an upgraded case. Connectivity relies on Bluetooth 5.3, and AirPods 4 are designed to pair quickly with Apple devices on the same Apple account, automatically switching between iPhone, iPad, Mac, Apple Watch, Apple TV and Apple Vision Pro in everyday use.

System Requirements and Accessibility Features

Apple lists system requirements for AirPods 4 that include iPhone and iPad models with the latest versions of iOS and iPadOS, Apple Watch with the latest watchOS, Macs running the latest macOS, Apple TV with the latest tvOS, and Apple Vision Pro with the latest visionOS. AirPods can also function as standard Bluetooth headphones with older Apple devices and non-Apple hardware, though certain advanced features may not be available in those cases. The tech specs mention accessibility features such as Live Listen audio, headphone levels and Headphone Accommodations, which can help users monitor sound exposure and adjust audio for hearing comfort. Apple’s accessibility description presents these as part of a broader effort to make AirPods usable for people with different needs.

Pricing and the ANC Version

In the United States, Apple AirPods 4 occupy the entry-level slot in Apple’s true wireless lineup. Multiple US-focused reviews note that the standard AirPods 4 are priced at $129, while a second AirPods 4 model that includes Active Noise Cancellation and a wireless charging case is priced at $179. A review from a US tech publication explicitly lists $129 for the non-ANC AirPods 4 and $179 for the AirPods 4 with ANC, noting that both versions became available in September 2024. Another analysis describes the $129 version as the cheaper open-ear option without ANC and confirms that it offers 5 hours of listening from the buds and 30 hours with the case, aligning with Apple’s official battery ratings. This same review cites a US price of $129 and a release date of September 20, 2024 for the standard model.

By contrast, the $179 AirPods 4 with Active Noise Cancellation add more advanced noise control modes, wireless charging capability for the case and features such as Adaptive Audio and Conversation Awareness, matching some of the conveniences found in AirPods Pro. One US review points out that on the ANC model, battery life drops to around 4 hours with noise cancellation activated and about 20 hours total when using the wireless charging case, compared with 5 and 30 hours on the non-ANC AirPods 4. The same Tom's Guide report summarizes this difference as a trade-off between added noise control features and slightly reduced battery stamina on the pricier version.

Environmental Design and Materials

Apple’s documentation for AirPods 4 includes specific information about materials and environmental goals. The company notes that AirPods 4 use 100% recycled tin in the solder of multiple printed circuit boards and 100% recycled gold in the plating of multiple boards, alongside 100% recycled copper plating salts on multiple printed circuit boards. Magnets in AirPods 4 employ 100% recycled rare earth elements, and several plastic parts incorporate 50% recycled plastic. Retail packaging is described as 100% fiber-based, excluding adhesives, inks and coatings from the plastic content calculation. The environmental section of Apple’s tech specs also indicates that AirPods charger systems meet U.S. Department of Energy requirements for battery charger efficiency and that final assembly sites for AirPods are part of Apple’s Zero Waste Program, which focuses on avoiding landfill waste.

From a chemical standpoint, Apple states that AirPods 4 are free of mercury, brominated flame retardants and PVC, following the company’s Regulated Substances Specification. Apple further explains that AirPods comply with European Union directives concerning hazardous substances, with some exemptions for lead in high-temperature solder that the company aims to phase out where technically feasible. These details provide concrete insight into how Apple approaches materials and environmental standards for its audio accessories, beyond broad sustainability claims.

Comparison to Earlier AirPods and Use Cases

Compared with earlier entry-level AirPods, AirPods 4 deliver a few notable quantified improvements, especially around durability and audio features. For instance, prior generations offered sweat and water resistance, but AirPods 4 add dust resistance and explicitly carry an IP54 rating for both buds and case, as recorded in Apple’s specifications and echoed by independent reviewers. The TechRadar review lists IP54 waterproofing and dust resistance for the earbuds and case, alongside a 5-hour official battery rating from the buds and 30 hours from the case. Moving from earlier AirPods to AirPods 4 also means stepping up to the H2 headphone chip, enabling features such as Personalized Spatial Audio and more precise Adaptive EQ, which were previously limited to higher-end models.

In daily use, the combination of 5 hours of rated listening time, IP54 dust and water resistance and a compact USB-C case suggests that AirPods 4 will suit users who frequently move between an iPhone, Mac or iPad and prefer an open-ear fit. For those spending more time in noisy environments or wanting wireless charging from the case and full noise control modes, the $179 AirPods 4 with Active Noise Cancellation represent a more capable option, albeit with slightly shorter battery life on a single charge. Across both versions, the core audio technologies and spatial features create a consistent listening platform for Apple’s ecosystem, while the standard AirPods 4 strike a balance between price, durability and feature set for US buyers.

Verdict and Position in the Earbud Market

Within the broader true wireless earbud market, the $129 Apple AirPods 4 position themselves as mid-range open-ear buds that prioritize seamless integration with Apple hardware, H2-powered audio processing and IP54 dust and water protection. The documented 5-hour single-charge battery life and 30-hour total case capacity place them in a competitive band for everyday use, especially for users who value rapid pairing, automatic device switching and Personalized Spatial Audio more than deep noise isolation. The existence of the $179 AirPods 4 with Active Noise Cancellation provides a clear upgrade path for those who need stronger noise control and wireless charging, while keeping overall design and software behavior similar.
