AirPods 4
Quick verdict: for open-ear listening with active noise cancellation, the V3 TB (Airoha 1571AM) is the current gold standard — featuring top-tier dual-mic hybrid ANC for an open-ear design, dual ST bone-voiceprint gyroscopes for head-tracking spatial audio, AI conversation awareness, and 1-to-3 multi-device switching. If you want seamless Apple ecosystem switching, the V2 Huilian provides iCloud Connect and Starfun EQ syncing. On a budget, the V2 TB / HR offers great open-ear sound with basic ANC.

Shared AirPods 4 Baseline
All AirPods 4 models feature: open-fit (non-in-ear) design, USB-C charging case with case speaker, Force Touch stem controls, Hey Siri, in-ear detection, and iOS 27 support with About page popup. (Note: No replica supports Apple's encrypted Find My network. Open-ear ANC naturally reduces less low-frequency rumble than silicone-tip in-ear Pro models.)

V2 Overview
The V2 tier offers reliable open-ear audio with slight differences depending on the manufacturer:
- Huilian 247: Features iCloud Connect for seamless switching between Apple devices logged into the same Apple ID, adaptive audio, and Starfun app support allowing custom EQ profiles to sync directly across to iOS.
- TigerBuilder / HR (Airoha 1563E): Reliable daily drivers with punchy open-ear sound and single-mic ANC. The HR version includes working head tracking, while the TB model uses fixed spatial audio and is tuned with a heavier bass emphasis.
