Apple's AirPods Pro 2, released in September 2022, have remained a benchmark for wireless earbuds. As we approach their third generation, rumors and patents suggest Apple is preparing significant upgrades that could transform these earbuds into comprehensive health monitoring devices while enhancing their already impressive audio capabilities.
Expected Release Timeline
Based on Apple's product cycle patterns, industry analysts predict the AirPods Pro 4 will launch in fall 2025, approximately three years after the current generation. This timeline aligns with Apple's typical refresh cycle for premium audio products and coincides with rumors of a redesigned charging case.
Health Monitoring Features
The most significant rumored addition is comprehensive health tracking. Multiple sources, including analyst Ming-Chi Kuo and Bloomberg's Mark Gurman, suggest Apple is developing sensors for the AirPods Pro 4 that could monitor various health metrics.
Body Temperature Sensing
Apple reportedly tested temperature sensors in AirPods Pro 4 prototypes. Unlike wrist-based temperature monitoring on Apple Watch, ear canal measurements provide more accurate core body temperature readings. This feature could help with:
- Fertility tracking and cycle prediction for women
- Early illness detection through fever monitoring
- Workout intensity optimization
- Sleep quality assessment
Heart Rate Monitoring
Patents filed by Apple describe optical sensors embedded in AirPods that could measure heart rate through the ear canal. Research shows that ear-based heart rate measurements can be more accurate than wrist-based readings during exercise, as the ear has better blood flow and less motion interference.
This capability would enable continuous heart rate monitoring without wearing an Apple Watch, making the AirPods Pro 4 a viable alternative for users who prefer minimal wearables during workouts.
Hearing Health Features
Following iOS 18's hearing health features, the AirPods Pro 4 may include clinical-grade hearing test capabilities and enhanced hearing aid functionality. Apple received FDA clearance for hearing aid features in AirPods Pro 2, and the third generation could expand these capabilities with:
- More precise hearing profile customization
- Real-time environmental sound adjustments
- Tinnitus management features
- Long-term hearing health tracking
Audio and ANC Improvements
Beyond health features, the AirPods Pro 4 are expected to receive substantial audio upgrades powered by a new H3 chip, succeeding the current H2 processor.
Next-Generation Active Noise Cancellation
Apple's ANC technology already leads the industry, but improvements are anticipated through computational audio advances. The H3 chip could enable:
- Adaptive ANC 2.0: Machine learning that better predicts and cancels irregular sounds like conversations and sudden noises
- Personalized ANC: Customization based on your ear shape and typical environments
- Wind Noise Reduction: Improved algorithms to combat wind interference during outdoor activities
- Conversation Awareness Enhancement: Better detection of when you're speaking to automatically adjust transparency mode
Audio Quality Enhancements
Rumors suggest support for lossless audio over Bluetooth using a new codec Apple developed. While standard Bluetooth doesn't support true lossless audio, Apple may implement proprietary technology similar to Sony's LDAC or Qualcomm's aptX Lossless, but optimized for Apple devices.
The improved driver design could expand frequency response, providing deeper bass extension and clearer highs. Spatial audio may receive upgrades with more precise head tracking and better room modeling.
Design and Usability Changes
While maintaining the iconic stem design, subtle refinements are expected:
USB-C Charging Case
Following the iPhone 15's transition to USB-C, the AirPods Pro 4 will almost certainly adopt USB-C charging. The case may also feature:
- Built-in speaker for Find My alerts (already in AirPods Pro 2 USB-C model)
- Improved battery capacity for longer total playback time
- Faster charging speeds
- Potential for reverse wireless charging capabilities
Enhanced Fit Options
Apple may introduce additional ear tip sizes or alternative designs to accommodate more ear shapes. Patents show exploration of ear tip designs with integrated sensors that maintain comfortable fit while housing health monitoring technology.
Software Integration
The AirPods Pro 4 will likely launch alongside iOS 19, featuring deeper integration with Health app and potential workout apps. Expected software features include:
- Comprehensive health dashboard combining data from AirPods, Apple Watch, and iPhone
- Automatic workout detection when wearing only AirPods
- Enhanced Siri capabilities with on-device processing
- Improved automatic device switching based on context
Pricing Expectations
The current AirPods Pro 2 retail for $249. Given the substantial feature additions rumored for the third generation, particularly health sensors, pricing could increase to $279-$299. However, Apple may maintain the $249 price point to remain competitive with premium offerings from Sony, Bose, and Samsung.
The AirPods Pro 4 represent Apple's vision of earbuds as health and wellness devices beyond simple audio playback. If rumors prove accurate, they could establish a new category of wearable health monitors that integrate seamlessly into daily life without the burden of additional devices.
