These sit in different size classes, so this is not a straight ranking comparison. The JBL Flip 6 ranks #13 of 179 medium speakers by sound quality at $79.95; the Marshall Willen II ranks #11 of 62 small speakers by sound quality at $129.99.
The JBL Flip 6 is the deeper-bass choice. A small, rugged speaker with very neutral sound for its size, an excellent choice for most people. Its bass reaches about 56Hz before falling 10dB, against 70Hz for the Marshall Willen II. It supports AAC Bluetooth, which the Marshall Willen II lacks. It links with other speakers (PartyBoost up to 100 speakers), which the Marshall Willen II cannot. Watch for: Some slight upper mids emphasis.
The Marshall Willen II is the longer-running, lighter option. A tiny waterproof strap on speaker with balanced sound, a long battery, and app EQ that clips easily onto a bag. It is rated for 17 hours of battery against 12 for the JBL Flip 6. At 0.8 lbs (360 g) it weighs noticeably less than the JBL Flip 6 at 1.2 lbs (544 g). Watch for: Not that deep of bass.
Buy the JBL Flip 6 ($79.95) for a medium speaker; the Marshall Willen II ($129.99) suits a small speaker instead.
