A compact, lightweight Bluetooth speaker designed for portability is the Bose SoundLink Flex. You may transport it outside without any problems because of its IP67 classification, which confirms that it is completely dust-tight and submersible in up to a metre of water for 30 minutes. Anywhere you go, the speaker’s PositionIQ technology adapts its music reproduction to the particular acoustics of your surroundings. The SoundLink Flex is 1.3 pounds heavy and has dimensions of 3.6 x 7.9 x 21 inches (HxWxD).
Although it feels heavy, the backpack won’t feel like it’s an anchor. Stone blue, black, and white smoke are the available colours. The Flex is wrapped in grippy silicone material in the non-grill regions to prevent slipping while you’re using it in the pool or other wet environments. The material’s propensity to accumulate dirt is the trade-off. Additionally, there is a tiny fabric utility loop so you may hang it on anything useful or dangle it on one finger. If you wanted to, you could connect a longer lanyard to the loop.
The speaker has an IP67 classification from Bose, which means it can tolerate being submerged in water for up to 30 minutes and that particles like dust, sand, and the like won’t get inside its electrical components, which are its most important elements. Although it’s not quite neutral buoyancy, it floats and is amusing to poke around in the water. The preceding page provides a detailed explanation of IP codes.
A single 60 mm (about 2.3 inches) full-range driver and two roughly 3-inch wide rounded rectangular radiators that fire forward and backward via the big front and smaller back grills are both located inside the Flex. The preceding link features an animated exploding illustration of the SoundLink Flex by Bose in the middle of the page. A microphone for taking calls and activating your smartphone’s voice assistant is also included.
The power, Bluetooth pair, volume up/down, and a multi-function button are located on top of the device, along with Bluetooth and power status lights. There are no other connections on the speaker, which is unique, and it only uses a USB-C port to recharge its battery.
Quick Bluetooth connectivity was experienced with the Bose SoundLink Flex (version 4.2 radio onboard). It’s fortunate that there isn’t an auxiliary input. With the 3.2aH battery, my runtime was approximately 7 hours during relatively light listening, with about 30% life (stated through voice prompt) still left. Up to 12 hours, according to Bose.
