Explains the Turn OFF Ultimate Ears Wonderboom 2 procedure here. Now most speakers have a Power button that they prominently place for easy access. Indeed, this model is no exception. Indeed we find its Power button right on top, near the front. We start here with the speaker running.
The Power button also has a light in it in the shape of a vertical line. This glows when the speaker is ON. It goes dark when you turn OFF the speaker. This lamp indeed tells when the unit is running or not.
Furthermore, this lamp is dark during speaker OFF time, unless you are charging the speaker. In that case, it glows red, as we see in the next picture.
Turn OFF Ultimate Ears Wonderboom 2: Step by Step
To power down this speaker, press the Power button. Then release after a quarter second or so. Moreover, you needn’t hold it in for too long. The speaker responds quickly by shutting down.
When the speaker shuts off, the Power button goes dark. Plus the speaker makes a distinctive power-down sound.
But if pressing the Power button does not work, it could be that the memory inside is corrupt. So if this problem persists, try hard resetting it.
But if after the reset the speaker still does not turn off, then the unit itself may be defective. So in that case, just get a new one. These can be had for little money on eBay and other online sales sites. In fact, you might get lucky and find new ones as new old stock from time to time.
