Best sounding busking speaker/portable PA speaker available. This was released by Bose in February 2018. This comes complete with the portable battery installed, which gives around 6 hours without mains power, along with the kettle lead for mains power connections/charging. Very powerful, lightweight & portable, which makes it perfect for busking and gigging musicians! Also features bluetooth connection. I will price match if you’ve seen this item cheaper elsewhere!
