Our Verdict
Anker Soundcore Liberty 4 NC Truly Wireless
Nothing Ear (a)
Depending on your use preferences, there are good reasons to choose either the Anker Soundcore Liberty 4 NC Truly Wireless or the Nothing Ear (a). The Anker have a longer battery life, use touch controls, and block our noise much better. However, the Nothing have a less bassy sound by default, which you may prefer, alongside greater overall dust and water resistance. If you accidentally trigger commands frequently, the pinch controls can help, too. However, their battery life is shorter.
