- Is the noise cancelling good enough for flights?
- It reduces engine drone noticeably, but it does not silence it as completely as flagship earbuds. It works well for commuting and office noise.
- How long does the battery last with ANC on?
- Anker rates up to 10 hours per charge; with ANC on you get somewhat less, and the case adds extra charges. Ten minutes of charging gives roughly 4 hours of playback.
- Does it work with iPhone?
- Yes, over Bluetooth with AAC. LDAC is Android-only, so iPhone users do not get the Hi-Res codec.
- Can I connect two devices at once?
- Yes. Bluetooth 5.3 multipoint lets you switch between two devices, such as a laptop and a phone, without repairing.
- Is it waterproof for swimming?
- No. IPX4 handles sweat and light rain but not submersion, so do not swim or shower with it.
- What is in the box?
- The earbuds, charging case, USB-C cable and multiple ear tip sizes. A wireless charger is not included.
