Short answer: the Marshall Willen for better sound quality, the Harman Kardon Neo for the lower price. The Marshall Willen ranks #14 of 47 small speakers at $120. The Harman Kardon Neo ranks #43 at $90, $30 cheaper.
What the Marshall Willen offers: Exceptionally clear vocals for a mono speaker. Solid, durable build with IP67 water/dust resistance. Extremely compact - fits in a back pocket. Watch for: Not that deep of bass. A bit of a sharp treble.
What the Harman Kardon Neo offers: IPX7 waterproof. Elegant matte-metal design with an attachment loop. Echo-cancelling mic for calls; goes louder than its size suggests. Watch for: Huge lack of bass.
Buy the Marshall Willen if sound quality is the priority over the price, or the Harman Kardon Neo if the price is the priority over sound quality.
The Harman Kardon Neo is not a sound-quality pick. It sits near the bottom of the 47 small speakers; there are better options higher up.
Battery life favors the Marshall Willen: rated for 15 hours against 10 hours for the Harman Kardon Neo.
There is a real gap in water resistance: the Marshall Willen at IP67 (brief submersion) against the Harman Kardon Neo, which has no water resistance.
