Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Boost “upgraded” 2021 is the better pick: it ranks #5 of 175 medium speakers by sound quality (rated 4.4/5), against #91 (rated 3.2/5) for the JBL Charge 3. If you want one new, the JBL Charge 6 replaces the JBL Charge 3 and is rated 4.2/5 at $119.95.
The Soundcore Boost “upgraded” 2021 is the better-sounding, deeper-bass option. A very neutral good sounding inexpensive small speaker with quite deep bass for the size. Its bass reaches about 56Hz before falling 10dB, against 63Hz for the JBL Charge 3. At 1.3 lbs (590 g) it weighs noticeably less than the JBL Charge 3 at 1.8 lbs (800 g). It has an adjustable EQ, which the JBL Charge 3 lacks. Watch for: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video.
The JBL Charge 3 is the longer-running pick. Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. It is rated for 20 hours of battery against 12 for the Soundcore Boost “upgraded” 2021. It keeps a wired aux input, which the Soundcore Boost “upgraded” 2021 lacks. It links with other speakers (Connect+ up to 100 speakers), which the Soundcore Boost “upgraded” 2021 cannot. The catch: Less clarity than the JBL Flip 4.
Buy the Soundcore Boost “upgraded” 2021 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the JBL Charge 6, which replaces the JBL Charge 3.
