JBL Flip 6 vs Sony ULT Field 3 (August 2026)

Short answer: the JBL Flip 6. It ranks #12 of 134 medium speakers at $129.95; the Sony ULT Field 3 ranks #57 and costs $148, so there is not much of a tradeoff to weigh.

What the JBL Flip 6 gets right: A very neutral speaker, very small, almost pocket size, a huge sound quality leap over the Flip 5. The catch: Not stereo.

On the Sony ULT Field 3 side: IP67 rated, dustproof and water resistant. The catch: Sounds a bit hollow, a bit boosted in the treble.

Buy the JBL Flip 6 if the ranking matters more than the price. Buy the Sony ULT Field 3 if the price matters more than the ranking.

Cons: Not stereo. Some slight upper mids emphasis. The TL version (made in Vietnam) tweeter can sound somewhat scratchy and doesn’t sound as good as the GG version (made in China)
