Hello...I`m thinking of getting a similar setup as you for Karaoke. I`m looking at some of the dolphin Bluetooth speakers. I`m interested in this one https://www.amazon.com/dp/B075D6HQTF/?coliid=I2JJZLD9ODZ7P6&colid=2GVX7OSTF5RRS&psc=1&ref_=lv_ov_lig_dp_it How is the microphone that comes with the speaker? Ill probably get a wireless mic set with it...and how is the built in reverb effects on the dolphin speakers? Do they sound like true reverb and not too much "echoy effect" if that makes any sense?
