JBL FLIP 5 ECO

Beating the drum for sustainability is all very well, but what if they can’t hear you at the back? Give it some welly with this great-sounding and green-minded wireless speaker. Durable, waterproof and good for 12 hours of wireless sound, the Flip 5 Eco is made from 90% recycled plastic. You can keep up the renewable theme by only listening to remixes on it. £120 / jbl.com
