Cannot completely uninstall E18 bluetooth headset

hi there

a while ago i bought a bluetooth headset, which i didn't like so i removed it and returned it.i uninstalled the device, yet it seems some pieces are still leftover on the PC, can you help?

there's a lot of E18 in the registry so dont wanna mess it up unless i know where to look, this is how it looks like, it's greyed out:




thanks,
Gabrio
