Fully water and dustproof portable mid-power speaker system with wireless Bluetooth connectivity, high-quality sound, built-in microphone, and good battery life from one of the industry's leaders, the American corporation Bose. The manufacturer positions it as a mid-range product designed for sound coverage in small rooms or open spaces (under any weather conditions except sub-zero temperatures).

The durable case materials (sturdy plastic, silicone, and rubber) protect against UV, scratches, sand, and other contaminants. Thanks to its IP67 protection level, the Bose SoundLink Flex II speaker is not afraid of rain or even full immersion in water. It can become a useful companion for walks, picnics, small friendly gatherings, and other outdoor events. It has relatively compact dimensions (90x201x52 mm) and a moderate weight (580 g), making it easy to carry by hand or in any bag or backpack.

For connecting to an audio source, which can be a smartphone, tablet, wireless player, or laptop, it uses the energy-efficient Bluetooth 5.3 wireless interface, providing high-quality digital signal transmission within a radius of up to 10 meters. The use of two active and one passive acoustic radiators allows the development of impressive power without compromising sound quality.

Towards Your Desires

The portable speaker Bose SoundLink Flex II has received an updated software platform, which was clearly lacking in the previous generation. The manufacturer took user feedback into account and expanded sound customization capabilities. The signature audio profile provides balanced playback with clear frequency separation, allowing each instrument to be heard separately, while vocals remain crystal clear. The bass feels confident and rhythmic, but its power might be insufficient for noisy parties. However, for most music genres — from pop and rock to classical and country — the speaker is perfectly suitable.

Advanced users have access to an equalizer, allowing them to fine-tune the sound to their preferences. The PositionIQ technology determines the device's orientation and optimizes sound directionality. In stereo pair or party mode, additional devices can be connected, and a separate customizable button is responsible for playback control, voice assistant activation, and launching music in Spotify. Thanks to Multipoint, the speaker synchronizes with two mobile gadgets at once, allowing quick switching between sources. Voice communication is also supported through a built-in microphone.

Focus on Convenience

The technology of the Bose SoundLink Flex II harmoniously combines with compactness and a remarkably lightweight — just 580 grams. The model is designed for active users who need powerful and clear sound during workouts, hikes, and outdoor recreation. This is confirmed by the technical parameters: the built-in battery provides about 12 hours of work without recharging, and the IP67-rated body withstands immersion in water, contact with sand, dirt, and dust.

The combination of silicone, metal, and plastic makes the body easy to use and resistant to accidental drops. A textile suspension allows the speaker to be attached to a backpack, safety system, or any other element with a carabiner or strap. Meanwhile, the gadget not only excels in music but also in voicing films or household tasks, making its application range extremely wide.
