Apple AirPods Pro 4 Launch: Real-Time Translation and Blood Glucose Monitoring at ¥2,799

Apple unveils AirPods Pro 4 with the custom H4 chip enabling real-time multilingual translation and continuous glucose monitoring, marking Apple's bold entry into the health wearables market.

Overview

Apple announced the all-new AirPods Pro 4 at WWDC 2027, featuring the proprietary H4 chip that brings real-time multi-language translation and continuous glucose monitoring (CGM) directly to the earbuds.

Starting at ¥2,799, a 15% increase over the previous generation, the device still sold over 2 million units on the first day of pre-order.

Key Upgrades

Real-Time Translation

AirPods Pro 4 supports instant translation across 40 languages. Both parties in a conversation simply wear one earbud each — no app, no screen, no interruptions. Translation is spoken directly into the ear with sub-800ms latency.

Crucially, all translation runs entirely on-device, never touching the cloud — critical for privacy-sensitive business negotiations.

Continuous Glucose Monitoring

In partnership with Abbott, Apple integrated CGM capabilities into the AirPods Pro 4 charging case. With a dedicated ear-hook accessory, users get 7-day, 24-hour continuous glucose monitoring, with data syncing seamlessly to Apple Health.

This is a significant breakthrough for diabetes patients, and marks Apple's official entry into chronic disease management.

Other Upgrades

  • Sound: Adaptive spatial audio now tunes in real time to the shape of your ear canal
  • Battery: 8 hours with ANC on, 32 hours total with the case
  • Water resistance: IPX8 rated, safe to wear while swimming

Competitive Landscape

Samsung quickly responded that Galaxy Buds Pro 4 will also receive translation features, priced at ¥1,999. However, industry insiders note that Apple's H4 chip's on-device AI inference capability still leads the market by at least 18 months.
