They praised its low directivity index, dual-device Bluetooth 4.2 pairing, and portable design. However, they were disappointed that it lacks a graphic EQ and doesn’t support stereo.

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.

Featuring a 0.22 frequency response slope, the Bose SoundLink Flex produces slightly better-balanced sounds than the JBL Flip 5 Bluetooth portable speaker with its -0.31 slope.
