AirPods Pro 3 vs. AirPods 4: Sound, Battery, and Key Features Compared

Sound Quality and Noise Cancellation

• 💡 AirPods Pro 3 feature Apple's latest acoustics, a new multiport architecture, adaptive EQ, and improved passive isolation with foam-infused tips.
• 🚀 They boast stronger active noise cancellation (ANC), with Apple claiming up to 2x more than the previous Pro generation.
• 🎧 AirPods 4 also received audio upgrades, including the H2 chip, adaptive audio, and spatial audio, with some versions offering optional ANC.
• ⚠️ Due to their more open design and lack of a tight in-ear seal, AirPods 4's ANC is less effective than the Pro version, especially in noisy environments.

Battery Life and Practical Usage

• 🔋 AirPods Pro 3 offer up to 8 hours of listening time with ANC enabled, and potentially more with transparency or other features.
• ⏳ AirPods 4 provide up to 5 hours of listening time in the base model with ANC enabled, or about 4 hours if it's the ANC version.
• 📊 With the charging case, AirPods 4 can reach up to 30 hours of total listening time, while AirPods Pro 3 offer 24 hours.
• 📉 In real-life usage, actual battery life may be shorter than advertised, with the speaker noting around six hours for the Pro 3s during work.

Advanced Features and Health Tracking

• ❤️ AirPods Pro 3 include a built-in heart rate sensor for accurate workout metrics and health tracking, measuring each second.
• 🏆 The sensor's accuracy is compared favorably to Apple Watch Ultra and even Garmin chest sensors.
• 💧 AirPods Pro 3 have an IP57 rating for dust and water resistance and come with five sizes of ear tips for a customizable fit.
• 👂 The Pro 3s offer enhanced ANC, better passive isolation, and more control over noise modes, including hearing protection certified to EN 352 standards.

Design, Comfort, and Use Cases

• ✨ AirPods 4 feature a lighter, smaller, and unique design that is comfortable for all-day wear due to its open nature, allowing ears to breathe.
• 🎯 They are better suited for casual listening and less demanding use, especially for those with smaller ears or who find silicone ear tips uncomfortable.
• ⚠️ The speaker notes that the AirPods 4's fit can be problematic for individuals with larger ears, leading to them falling out.
• 🧼 AirPods Pro 3 have a grill on each ear tip, making them simpler to clean and maintain sound quality, with ear tips being washable.
• 🧼 AirPods 4 have only one original grill, requiring more frequent and thorough cleaning, potentially with isopropyl alcohol and a brush, to maintain sound quality.

Deciding Between the Two

• 🎯 If noise cancellation, immersive sound, health features, and optimal audio in varied environments are priorities, the AirPods Pro 3 are likely the better choice.
• 🏠 For simpler usage in quiet rooms or offices, or if the AirPods 4's shape is preferred for comfort and breathability, the AirPods 4 are a viable option.
• ✅ The choice also depends on ear fit; if the Pro 3's silicone tips are uncomfortable or don't seal well, the AirPods 4 might be a better fit, provided they stay securely in place.
