Both headphones include an in-line remote and MEMS microphone. This allows users to take calls, control playback, and access voice assistants without touching the device.
In everyday use, they can be used without charging and can provide near-zero latency, which is relevant for gaming and video syncing. No battery means there is no worry of battery degradation over time.
