Everything is connected properly but I can only hear the music. I feel no haptics.

As Woojer Series 4 devices are driven by sophisticated software, this may be caused by a software "glitch". It can happen for example when switching the audio source from Bluetooth to 3.5mm. If you're experiencing such behavior, try the following:

1. Make sure only a single connection type (e.g.: Bluetooth, 3.5mm, USB-C) is active at a time.
2. Try to perform a hard reset. Please refer to the following article to learn how to perform the Hard Reset.
3. When connecting with a USB-C cable and a PC: Disconnect the Woojer, turn it off and then turn it on again, re-connect the cable to a different USB port (make sure that the Woojer is ON before connecting it to the PC), and wait until your PC identifies the Woojer.
