Short answer: the EarFun Uboom L for sound quality, unless you need JBL’s extra battery life and durability. It ranks #2 of 172 medium speakers against the Charge 6’s #12, and costs $70.16 less.
The tuning gap is the whole story here. The Uboom L was tuned by Oluv and measures as one of the most neutral Bluetooth speakers around, sounding correct at every volume level because it boosts bass and treble at low volumes to match the ear’s equal-loudness curve. The Charge 6 improves on the Charge 5’s rolled-off treble but still has a distinctly V-shaped response: boosted bass by default, recessed mids, and some brightness above 2kHz.
The Charge 6 answers back with battery, ruggedness, and party features. It runs 24 hours against the Uboom L’s 16, carries an IP68 rating versus IP67, and adds Auracast party mode and USB-C power bank output, none of which the Uboom L offers. The Uboom L counters with an aux input, a built-in microphone, and true stereo output, none of which the Charge 6 has.
One real usability catch on the Uboom L: Bluetooth latency is 400ms unless you enable low latency mode (66ms), and that mode doesn’t work once two units are TWS paired, so video watchers in stereo-paired setups may notice lip sync issues the Charge 6 doesn’t have.
Buy the EarFun Uboom L for the most neutral, correct-sounding tuning available at this price, unless lag while TWS paired is a dealbreaker.
Buy the JBL Charge 6 if you need longer battery life, tougher waterproofing, or Auracast party pairing more than you need flat frequency response.

One of the strongest small-speaker values for music: reviews praise clear vocals, a natural overall balance and a genuinely convincing stereo image when two are paired.
