Bose Soundlink Flex 2nd gen vs Tribit Stormbox Pro

Last updated: August 19, 2026

Short answer: the Bose Soundlink Flex 2nd gen for better sound quality, the Tribit Stormbox Pro for the lower price. The Bose Soundlink Flex 2nd gen ranks #33 of 136 medium speakers at $129.99. The Tribit Stormbox Pro ranks #40 at $90, $39.99 cheaper.

The case for the Bose Soundlink Flex 2nd gen: Pretty much identical sounding to the 1st gen. The catch: Not stereo. Warm sounding with overly boosted bass which drowns out midrange detail.

What the Tribit Stormbox Pro gets right: 24 hour battery life (60% volume, XBass off); doubles as a power bank. Watch for: Bottom woofer was fixed in a later firmware, upgrade for best sound. Peaky mids, highs rolled off.

Buy the Bose Soundlink Flex 2nd gen if sound quality matters more than the price. Buy the Tribit Stormbox Pro if the price matters more than sound quality.

If battery life is a priority, the Tribit Stormbox Pro is rated for 24 hours versus 12 hours for the Bose Soundlink Flex 2nd gen.
