what should i buy?

question for project

Hey! I am prototyping a mockup for a college project and need some low profile speakers that can pair to each other. I would want to pair 4.

I initially bought the ones that come in a pair ( https://www.amazon.com/LEICEX-Bluetooth-Portable-Wireless-Speakers/dp/B0BPNYY61M?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=A1D5XWWXZRFZ6B) but i cant synchronize two pairs of those. So far i am not going into audio quality, so whatever speakers can be paired and are considerably small would work. Thank you!

My bad, i forgot to add the text
