Product Q&A
Will it connect to the JBL boombox
Is there a mode where the lights can remain on but there's no audio coming out of the speaker? If so, how's the battery life in such a scenario, provided the product is only used as a light over one battery cycle?
How much better is the pulse 4 compared to the pulse 3
Can the brightness of the light be dimmed?
Can it stay stationary on a certain color?
is it possible to keep the color of the screen blue and how do you do it
Im having my trouble with my pulse 4.I turned on the speaker and I tried turning it off and it won't turn off.I tried factory resetting it and won't turn off.
Why can’t the Pulse 4 connect to Link Portable?? I wanted Google Assistant and thought I could at least link the Pulse to Link Portable, which has Google Assistant, but no! Deal breaker for me. Pulse is just a pretty light show otherwise.
