The Marshall Willen II is the better-sounding, deeper-bass option. More balanced than the first Marshall Willen, no sharp treble. Its bass reaches about 70Hz before falling 10dB, against 105Hz for the Harman Kardon Neo. It is rated for 17 hours of battery against 10 for the Harman Kardon Neo. It is rated IP67, while the Harman Kardon Neo has no water resistance. Watch for: Not that deep of bass.
The Harman Kardon Neo is the lighter choice. IPX7 waterproof, with an attachment loop and an echo-cancelling microphone for calls. At 0.6 lbs (251 g) it weighs noticeably less than the Marshall Willen II at 0.8 lbs (360 g).
