These are not really the same size class, and that is the honest framing here. The Marshall Stockwell II ranks #11 of 120 large speakers by sound quality at $229.99; the JBL Flip 6 ranks #13 of 179 medium speakers by sound quality at $79.95.
The Marshall Stockwell II is the deeper-bass, longer-running 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 56Hz for the JBL Flip 6. It is rated for 20 hours of battery against 12 for the JBL Flip 6. It keeps a wired aux input, which the JBL Flip 6 lacks. The catch: Not very loud, and the added DSP reverb may annoy purists.
The JBL Flip 6 is the lighter, tougher choice. A small, rugged speaker with very neutral sound for its size, an excellent choice for most people. At 1.2 lbs (544 g) it weighs much less than the Marshall Stockwell II at 3.1 lbs (1.4 kg). It is rated IP67 against IPX4 for the Marshall Stockwell II. It supports AAC Bluetooth, which the Marshall Stockwell II lacks. Watch for: Some slight upper mids emphasis.
Buy the Marshall Stockwell II at $229.99 for a large speaker, or the JBL Flip 6 at $79.95 for a medium speaker instead.
