Nothing's first open-ear headphones keep you aware of your surroundings

Regardless of which model you choose, the AirPods 4 represent a substantial upgrade over their predecessor. Both pairs of earbuds deliver better sound than the second-gen AirPods, with more bass than the third-gen AirPods. They also sport the Voice Isolation feature found in the latest AirPods Pro, which uses a series of machine learning algorithms to isolate your voice in noisy environments, resulting in clearer voice call quality.
