SONY WF-C500 IPX4/20Hrs Battery Life Bluetooth Headset??(Black, True Wireless)

SONY WF-C500 IPX4/20Hrs Battery Life Bluetooth Headset (Black, True Wireless).
Designed small (45% smaller than the WF-XB700), these buds fit securely and comfortably in your ears. The rounded shape without edges makes them a pleasure to wear, leaving you free to focus on your music. WF-C500 headphones combine a shape that matches the ear cavity with a new ergonomic surface design for a more stable fit. DSEE restores high frequency sounds lost in compression. The cylindrical charging case is extremely small and easy to carry around in a pocket or bag. Conversation flows freely with easy hands-free calling, now clearer than ever with a high-quality built-in microphone. If you want to listen to your music while still being able to have a conversation, remove one earbud only from the charging case and use as normal. The buttons let you play, stop, or skip through tracks and adjust the volume. You can also access your smartphone?s voice assistant. As if you are there at a live concert or with the artist recording in a studio. With 360 Reality Audio, music has never been so immersive and so real. Up to 10hr battery life, total up to 20hr with charging case.
