Short answer: the JBL Flip 7 for better sound quality, the Earfun Uboom Slim for the lower price. The JBL Flip 7 ranks #14 of 136 medium speakers at $129.95. The Earfun Uboom Slim ranks #38 at $79, $50.95 cheaper.
What the JBL Flip 7 gets right: A very neutral speaker, very small, almost pocket size. Just slightly more treble than the Flip 6 which was already a great speaker. The catch: A little bit of a bump at 4khz, not quite as neutral as the FLip 6. I believe this one is slightly worse than the Flip 6.
On the Earfun Uboom Slim side: Excellent pricing, strong waterproof build (IPX7), good battery life (16 hours), smooth sound with volume compensation, speakerphone capability. Watch for: Not as deep bass as others. Warm tuned, peaks in the mids and lower treble, rolled off upper treble.
Buy the JBL Flip 7 if sound quality matters more than the price. Buy the Earfun Uboom Slim if the price matters more than sound quality.
