Consensus
our Verdict
Reviewers praised the Bose SoundLink Flex, recommending it for outdoor use, podcasts and music. Editors at Tech Hive loved its speakerphone functions and IP67-rated water-proof and dust-proof design. Analysts at PCMag hailed its portable 1.3-lb construction. Experiments revealed a 60.8Hz to 15.6 kHz frequency response range and near-neutral 0.22 slope, producing balanced sounds. This device has a good 87.5 dB maximum SPL and 3.02 dB DRC, showing some sound quality deterioration at the highest volume. Check out our Bose S1 Pro System review for a louder Bluetooth device. It has a 4.59 dB in directivity index, offering an average soundstage performance. The device has a tested 7.2 hr-battery life and excellent smartphone-based voice assistant functions. This product supports dual-device Bluetooth pairing, boasting a decent 109 ms Android Bluetooth latency and 236 ms iOS Bluetooth latency. However, it downmixes stereo to mono and lacks a graphic EQ. Check out the Bang & Olufsen Beosound Explore review for a graphic EQ.
