I have the Roku - Streaming Stick+ 4K Headphone Edition with Voice Remote with TV Power and Volume Streaming Media Player - Model 3811R that was exclusive to Best Buy. The Remote broke and I need a replacement. I do not see a remote replacement with that model number. Can you advise which replacement is compatible?
You won't find an exact remote, but the Enhance Voice remote has everything yours had but adds two programmable keys that you will be able to program with your stick+ 3811. These extra keys hold a vice search prompt. Its on back order now.
