Harman Kardon via eBay offers the refurbished JBL Link 10 Smart Waterproof Wireless Bluetooth Speaker in Black for $49.99 with free shipping. That's tied with our January refurb mention, which didn't include a factory warranty, and the best price we could find for a refurb elsewhere by $10. It features a microphone with Google Assistant. Note: A 1-year Harman Kardon warranty applies.
