The SoundLink Flex Blue Dusk is the second-generation Bose SoundLink Flex in a deep blue with a muted grey edge, the colour of the sky just after sunset. It is the same compact speaker as every other Flex colour: an IP67 body that keeps out dust and water and even floats, PositionIQ that adjusts the sound to how the speaker is placed, up to 12 hours of playback and Bluetooth 5.3 with multipoint. Blue Dusk is the colour to pick if the speaker spends its weekends near water, on the sand or on a boat.

What Blue Dusk looks like
Blue Dusk is darker and greyer than a bright royal blue, so the SoundLink Flex Blue Dusk looks calm rather than sporty. The silicone back and the fabric grille share the same shade, and the nylon utility loop matches. On a beach towel, a pool deck or a boat bench it blends with the water and the sky instead of shouting. The darker tone also hides light scuffs and fingerprints better than the pale colours, although salt marks and fine sand can show up on the grille until it is rinsed.
Built for the beach and the pool
This is where the SoundLink Flex Blue Dusk makes the most sense. The IP67 rating covers dust and immersion, and the speaker floats if it goes into the pool. Bose is clear that it is not designed to be used in water: it tolerates accidental drops for up to 30 minutes, and you should rinse it with fresh water after contact with salt or chlorinated water. In practice that means you can leave the SoundLink Flex Blue Dusk by the pool edge or on wet sand without worrying, then wash it under the tap when you get home.
PositionIQ and the sound
PositionIQ senses whether the SoundLink Flex Blue Dusk is standing upright, lying on its back or hanging upside down, and adjusts the audio for that orientation. On a beach the speaker often ends up lying on a towel or propped against a bag, so this automatic tuning saves you thinking about placement. The adjustable EQ in the Bose app lets you add or reduce bass and treble, and the programmable shortcut button can be set for Spotify playback or your voice assistant.
Battery, charging and connection
Bose rates the SoundLink Flex Blue Dusk at up to 12 hours per charge, measured at 50% volume, 20–25°C and the default EQ; louder playback and summer heat will shorten that. A full charge of the SoundLink Flex Blue Dusk takes about 4 hours with a 5V/1.5A USB-C supply, which is not in the box, only a USB-C to USB-A cable. Bluetooth 5.3 keeps a stable connection within about 9 metres and multipoint holds two source devices, so two friends can take turns choosing music.
The rest, in brief
The speaker measures 20.1 x 9.0 x 5.2 cm and weighs about 0.59 kg, with an aluminium, fabric, nylon, plastic, silicone and steel build. A built-in microphone handles calls. Two compatible Bose speakers link through the shortcut button in Stereo Mode (left and right) or Party Mode (both play the same), and SimpleSync extends audio from a Bose smart soundbar or speaker. Bose does not list Bluetooth codecs on the product page.
Who This Is Not For
The SoundLink Flex Blue Dusk is not a party speaker for a large crowd: it is a compact speaker for a small group. It is not meant to be used in the water, only to survive accidental drops. There is no power adapter in the box, no 3.5 mm input, and Bose does not publish codec support. Summer heat at the beach can cut the 12-hour figure, which Bose measures at 20–25°C.
