Short answer: the Bose Soundlink Flex 2nd gen if sound quality matters most, the Oontz Angle 3 if price matters most. The Bose Soundlink Flex 2nd gen ranks #35 of 150 medium speakers, rated 3.8/5, at $159. The Oontz Angle 3 ranks #146, rated 2.1/5, at $28, $131 cheaper.
The case for the Bose Soundlink Flex 2nd gen: A very portable 586g, IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. The tradeoff: One Flex remains mono and cannot deliver genuine low-bass rumble; RTINGS also found the elevated treble can turn hi-hats and other high-frequency detail piercing.
The case for the Oontz Angle 3: At 580 g, Oontz Angle 3 combines 2x precision acoustic drivers + 1x passive bass radiator with Bluetooth and aux. Watch for: Bass is limited by its 138Hz specification.
Buy the Bose Soundlink Flex 2nd gen if sound quality matters more than the price. Buy the Oontz Angle 3 if the price matters more than sound quality.

The Two Speakers In Full
Bose Soundlink Flex 2nd gen: $159.00 Amazon eBay
Older model: the Bose Soundlink Flex (ranked lower, rated 3.8/5).
Pros: A very portable 586g, IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. The second generation adds a Bose app with 3-band EQ, better-placed controls and stereo pairing with another Bose Soundlink Flex 2nd gen. It supports AAC and aptX Adaptive in addition to SBC, making it a stronger wireless option than most small rivals.
Cons: One Flex remains mono and cannot deliver genuine low-bass rumble; RTINGS also found the elevated treble can turn hi-hats and other high-frequency detail piercing. The claimed battery life is only 12 hours, and some owners report accelerated standby drain after firmware updates. It is expensive for its size, so the added app and codec support, not a transformational sound upgrade over the original, are the main reasons to choose it.
