Question 1

If I buy 2ea( 2pair x 2pair ), they could be grouped to play same music ?

Accepted Answer

You’re best off using Google Home to do this with multiple pairs.  I “cast” Pandora across my house.  It can be a bit unreliable.andglitchy, but it’s nice when it works.

Question 2

I'm having an issue with the bluetooth connectivity... specifically, when I connect to my computer there is lag between the visual and sound. I can't watch movies at all with these speakers... how do I fix this lag issue?

Accepted Answer

thanks for asking this, as i was planning to use this for YouTube/Twitch video.  good to know.
if you are using VLC player, you can adjust the audio timing with "J" and "K" keys.  thats just a band-aid, tho.  network lag can't be entirely removed.

Question 3

how are these speakers powered?

Accepted Answer

see link under the tab Warranty & Returns; go to the manufacturers product page and click on the spec sheet. Answer is plug-in: 100-240vac, 50/60Hz, 60watts. Also, the Q&A on the JBL site states that there is no battery; these speakers need to be plugged in full-time.
