Sanwa Supply Open Ear Headset (Air Conduction) 400-BTSH027

This is an open-ear Bluetooth headset that allows you to hear surrounding sounds. Unlike bone conduction types, it has less vibration, making it a comfortable air conduction earphone for long wear.
You can listen without blocking your ears, so you can hear surrounding sounds and feel secure. It can be used for listening to music while running or doing housework, as well as for calls on construction sites.
It is designed to minimize sound leakage, which is common with open-ear types. It features noise-canceling, reducing surrounding noise during calls.
The external microphone is detachable with a magnet, allowing for clear calls by bringing the microphone close to your mouth.
It can be used for web conferences at home or for telework, Zoom calls, and on-site calls. *When the external microphone is removed, please attach the microphone terminal cover.
Operation is done via physical buttons, reducing accidental operations.
It is IPX5 waterproof, designed to be resistant to sweat and rain.
The design can be used with glasses and masks. Since it doesn't block your ears, it remains comfortable without your ears getting stuffy even when you move.
It is equipped with a large-capacity battery that allows for up to 10 hours of talk time. It can be charged with the included USB Type-C cable.

This is a Bluetooth earphone with noise-canceling for online meetings.

Although it has high functionality, I am selling it because I will not be using it. I only took it out once to test it.
