Black Bose SoundLink Flex 2nd Gen portable Bluetooth speaker

Why this model

The Bose SoundLink Flex (2nd Gen) is a flat, IP67-rated portable Bluetooth speaker for anyone who wants clean Bose sound in a 590 g package you can carry from the patio to your desk without a second thought. It suits people who mostly listen alone or with one other person, at home or outdoors.

This second generation keeps the understated design of the original and moves to Bluetooth 5.3, with multipoint, PositionIQ and the Bose app. Here’s our SoundLink Flex 2nd Gen review: its design, everyday use, key specs, and who it’s for (and who it isn’t).

Bose SoundLink Flex 2 design: understated, flat and tough

The SoundLink Flex keeps its flat, rectangular shape at 20.14 × 9.04 × 5.23 cm, and it works standing on a shelf or lying on a table. Bose lists a mix of aluminium, fabric, nylon, plastic, silicone and steel: the metal front grille and silicone edges give it a low-key look that sits well on a tidy desk.

Black is the most versatile finish. The buttons are physical and grouped on top, including a programmable shortcut button. At 0.59 kg it disappears into a backpack, and the IP67 rating means you can leave it by the pool or in the sand without worrying.

Everyday use: from desk to terrace

Thanks to multipoint, the SoundLink Flex stays connected to two paired sources and switches to whichever one is playing, which is handy if you move between your work laptop and your phone. The built-in mic also lets you take hands-free calls with the play/pause button.

PositionIQ detects whether the speaker is upright, lying flat or hanging and adjusts the sound to match. In the Bose app you can set the EQ, the shortcut button and SimpleSync. Add a second SoundLink Flex (2nd Gen) and you can use Stereo or Party mode for a terrace or a barbecue.

SoundLink Flex 2nd Gen key specs

According to Bose, battery life reaches up to 12 hours (measured at 50% volume, 20–25 °C, default EQ), and a full recharge takes 4 hours from a 5 V/1.5 A (7.5 W) USB-C source. There’s no wall adapter in the box, just a USB-C to USB-A cable.

For connectivity you get Bluetooth 5.3 with a nine-metre range according to Bose. The IP67 rating makes it dust-tight and water-resistant: Bose says it can survive 30 minutes of accidental immersion but isn’t designed for use underwater. It has no headphone jack, no Wi-Fi and no port for charging a phone.

Who it’s for (and who it isn’t)

The SoundLink Flex 2nd Gen is for you if you want a small, good-looking and rugged Bluetooth speaker that goes where you go: your home office, the bathroom, the balcony, holidays. Its flat shape and plain black finish also make it a speaker you can leave out without it cluttering the place.

It isn’t built to fill a big living room or power a party at full volume. A larger speaker such as the SoundLink Max or SoundLink Home will do that job better. And if you want a Wi-Fi speaker that joins a multiroom system, a Wi-Fi speaker is the better fit.
