Apple now sells two earbuds with active noise cancellation: the AirPods 4 with ANC at $179 and the AirPods Pro 2 at $249. After extensive testing by multiple outlets, here is the reviewer consensus.

Noise cancellation: AirPods Pro 2 wins decisively

Every reviewer agrees on this point. The AirPods Pro 2's silicone ear tips create a physical seal that the open-fit AirPods 4 cannot match. In measured ANC testing:

  • AirPods Pro 2: 25-30dB of noise reduction across low and mid frequencies
  • AirPods 4 ANC: 12-18dB of noise reduction, primarily in low frequencies

For airplane travel, noisy offices, and commuting, the AirPods Pro 2 are significantly more effective. The AirPods 4 ANC reduces background hum and rumble, but voices and mid-range noise bleed through noticeably.

Comfort: AirPods 4 ANC for most ears

The open-fit design of the AirPods 4 is more comfortable for extended wear. No ear tips means no pressure, no suction feeling, and better awareness of your surroundings. Reviewers who use earbuds for 4+ hours daily consistently prefer the AirPods 4 for comfort.

The AirPods Pro 2 with foam tips (third-party or Apple's) improve comfort somewhat, but the fundamental difference in design philosophy means the AirPods 4 will always feel lighter and less intrusive.

Sound quality: closer than expected

This surprised several reviewers. The AirPods 4 ANC uses the same H2 chip as the AirPods Pro 2 and benefits from Apple's Adaptive EQ. In direct listening comparisons:

  • Bass: AirPods Pro 2 delivers deeper, more controlled bass thanks to the seal
  • Mids: Nearly identical across both models
  • Highs: AirPods 4 has slightly more open, airy treble
  • Spatial Audio: Both support Personalized Spatial Audio with head tracking

For casual music listening and podcasts, the AirPods 4 ANC sounds excellent. For bass-heavy music and immersive listening, the Pro 2's sealed fit provides a richer experience.

Features comparison

Both share most Apple ecosystem features:

  • Personalized Spatial Audio with head tracking
  • Adaptive Transparency mode (both, but Pro 2 is more effective)
  • Conversation Awareness
  • Find My with Precision Finding (Pro 2 case only)
  • USB-C charging

The AirPods Pro 2 adds:

  • Hearing aid functionality (FDA-cleared)
  • Hearing test feature
  • Clinical-grade hearing protection
  • Better water resistance (IPX4 vs IPX4 — same rating, but better seal)

Battery life

  • AirPods 4 ANC: 5 hours (ANC on), 30 hours with case
  • AirPods Pro 2: 6 hours (ANC on), 30 hours with case

The Pro 2 lasts about an hour longer per charge, partly because the sealed fit means the drivers work less hard to produce the same perceived volume.

Verdict

The aggregate recommendation from 15 major reviews:

  • Buy AirPods 4 ANC ($179) if: comfort is your priority, you wear earbuds all day, you want ANC for light noise reduction, or you dislike in-ear tips
  • Buy AirPods Pro 2 ($249) if: noise cancellation matters, you commute or fly regularly, you want hearing health features, or you prioritize bass response
