Short answer: the Harman Kardon Esquire 2 for better sound quality, the Ultimate Ears Roll 2 for the lower price. The Harman Kardon Esquire 2 ranks #120 of 136 medium speakers at $200. The Ultimate Ears Roll 2 ranks #125 at $100, $100 cheaper.
On the Harman Kardon Esquire 2 side: Doubles as a conferencing speakerphone with a 4-mic array and noise/echo cancellation. Watch for: Bass is weak, vocal and instrument separation is underwhelming and sounds tinny at high volume.
The case for the Ultimate Ears Roll 2: Thin, flat profile fits easily in a bag or purse; light at 0.73 lb. Built-in bungee cord for hanging from a hook, nail, or door handle. The tradeoff: Not stereo. Barely any bass, rolled off treble off axis.
Buy the Harman Kardon Esquire 2 if sound quality matters more than the price. Buy the Ultimate Ears Roll 2 if the price matters more than sound quality.
If sound quality matters at all to you, skip both of these and look higher up the 136 medium speakers instead.
If water resistance matters to you, the Ultimate Ears Roll 2 at IPX7 (brief submersion) holds up far better than the Harman Kardon Esquire 2 at IPX4 (splashing).
