So sound is delivered by one full-range dynamic driver and bolstered by a couple of passive radiators. Bose isn’t exactly making with the details of amplification, or DAC, or driver configuration - but there are some things we know and others we’re prepared to speculate about. The SoundLink Flex is just as thoughtfully specified elsewhere.


Battery life of twelve hours or so (as long as you’re not listening at top volume, of course) adds to its ‘go-anywhere’ credentials, and should the worst happen the Flex can be brimming with power again after a couple of hours on the mains via its USB-C socket. Thanks to accelerometers (or ‘PositionIQ’, as Bose would rather self-importantly have it), the Flex knows its orientation and will adjust its EQs accordingly.Īn IP67 rating suggests the Bose will resist exposure to water and dust for far longer than any conscientious owner will allow, and by way of a little party piece the Flex is buoyant enough to float in water. There are little moulded feet to allow the Flex to lie on its back or stand upright in ‘landscape’ mode, while a durable fabric loop at one end means it can hang off a hook or carabiner. The chassis (available in black and ‘smoke’ white as well as the ‘stone’ blue of our review sample) is mostly of soft-touch silicone with quite a lot of ‘give’ in it, while the front grille is of powder-coated steel. So the Flex is small enough (just 9 x 20 x 5cm), light enough (600g) and, crucially, robust enough to fit the bill. Some brands seem to think being battery-powered and light enough to pick up makes a speaker ‘portable’, but Bose understands what’s required. Resilient materials and sturdy constructionįirst things first: the Bose SoundLink Flex, unlike quite a few nominal rivals, is an authentically portable Bluetooth speaker.IP67 rating for water and dust resistance.(Image credit: TechRadar) Design and features
