These sit in different size classes, so this is not a straight ranking comparison. The Marshall Stockwell II ranks #11 of 120 large speakers by sound quality at $229.99; the JBL Charge 6 ranks #12 of 179 medium speakers by sound quality at $149.95.
The Marshall Stockwell II is the deeper-bass choice. A light, strap equipped speaker with some of the most natural sound around, even off to the side, and a long battery. Its bass reaches about 44Hz before falling 10dB, against 53Hz for the JBL Charge 6. It keeps a wired aux input, which the JBL Charge 6 lacks. The tradeoff: Not very loud, and the added DSP reverb may annoy purists.
The JBL Charge 6 is the louder, lighter choice. A waterproof medium speaker with a long battery and a power bank output, with more balanced sound than older Charge models. Alan Ross Reviews measured it at 102dB at full volume, against 96dB for the Marshall Stockwell II. At 2.2 lbs (990 g) it weighs noticeably less than the Marshall Stockwell II at 3.1 lbs (1.4 kg). It is rated IP68 against IPX4 for the Marshall Stockwell II. The tradeoff: Still some boosted bass by default.
Buy the Marshall Stockwell II at $229.99 for a large speaker, or the JBL Charge 6 at $149.95 for a medium speaker instead.
