The Nothing Ear buds have amazing Bluetooth connectivity. They support multi-device pairing with two devices. You can also choose Bluetooth codecs specific to your needs: LDAC, LHDC, AAC, and SBC. LDAC and the less common LHDC can provide high-quality audio. Meanwhile, AAC is optimal for iOS users, and SBC is the more basic option. On the downside, while the companion app has a ‘Low Lag Mode,’ which reduces SBC latency significantly, it’s still too high to remedy lip-sync issues, and without the mode enabled, it’s worse—closer to the LDAC’s high latency measurement. Latency is fine if you’re listening to music (and often expected with high-quality codecs like LDAC), but the lag isn’t low enough to avoid disruptive lip-sync mismatches while streaming videos. While latency varies depending on many factors, including connection strength, operating systems, and whether you’re using an app that compensates or not, all of the codecs tested were pretty high in latency. However, we don’t have a test instrument for LHDC, which is supposed to be a low-latency codec. Your experience with a different configuration could yield other results, though.
