MEE audio SleepTones feature ultra-low-profile earpieces made out of a soft silicone material that helps reduce pressure points, delivering improved comfort for small ears and side sleepers. The sound, tuned to be smooth and non-fatiguing, is easy on the ears, making your favorite white noise app, music, audiobooks, or podcasts easy to enjoy. With an in-line mic and controls, you can adjust volume, skip tracks, take calls, or use your voice assistant without reaching your phone. Best of all, wired SleepTones are always ready to use - no battery anxiety and no charging required.
