Who it's for
Android owners who want the widest hi-res codec choice, and anyone who wants multipoint plus a hi-res codec: aptX Adaptive and aptX Lossless keep working with two devices connected, LDAC does not.
Caveats
- Turning LDAC on disables multipoint; LDAC with adaptive ANC drops battery to about 6 h per charge.
- ANC measured 7.5 out of 10 in SoundGuys' lab, below the soundcore Liberty 4 NC (8.4) and Space A40 (8.5).
- Single-tap volume can trigger when you adjust the bud; remap or disable it in the app.
- EarFun's support forum has repeated threads about one bud (usually the left) going silent or not pairing; forgetting and re-pairing fixed most.
- Mic is average in noisy places; call quality is best on Snapdragon Sound phones.
