This is the Bluetooth speaker/mic set we have! We are using it for an outdoor ceremony with 80-100 people. The sound carried really well and sounded clear during testing at the venue. Bluetooth connectivity worked great. It is currently about $82 but we caught it on sale for about $70 late last year. https://www.amazon.com/dp/B0783S9CJ4?ref_=cm_sw_r_apan_dp_JF73W98VGS7D3BG153ZA
