Shure SM58 with Boss Digital Wireless System vs SubZero P10 portable PA: which should I buy?

These packages serve different purposes: the Shure SM58 with Boss Digital Wireless System is a microphone-and-wireless package, while the SubZero P10 includes a portable PA speaker, Bluetooth and a wireless microphone.

At the supplied best new price of £330, the Shure package makes more sense if you already have amplification and want a vocal microphone with wireless connectivity. It does not include a PA speaker.

At £150, the SubZero P10 is the more practical choice if you need the speaker as well as a microphone. The supplied details do not establish sound quality, wireless range or suitable audience size, so do not assume either package is better on those measures.
