Unable to connect blue tooth

It appears they are wireless ear buds. You will have to check the directions for the device to put them into discovery/pairing mode. There should be directions when you purchased them, or you can check the manufacturer website. Once you have put them into discovery/pairing mode, then check the Watch Bluetooth settings, and you should be able to see and connect the devices.

Make sure you have cleared previous pairings from them and put them in pairing mode. If you have previously connected them with a different device make sure you turn off BT on that device or make sure it is far enough away to not auto connect.

Is that a health device or Bluetooth speaker?

Your watch will continue to search for any bluetooth device in the area. including the two you removed.
