Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Harman Kardon Esquire Mini 2 is the better pick: it ranks #58 of 63 small speakers by sound quality (rated 2.4/5), against #60 (rated 2.3/5) for the Lenovo 700 Ultraportable Bluetooth Speaker. Both are rated below 3.0/5 among the 63 small speakers; for better sound, the Tribit Stormbox Micro 2 ranks #1 at $35.39.
The Harman Kardon Esquire Mini 2 is the deeper-bass pick. A slim, stylish speaker that doubles as a speakerphone and a USB power bank, with a metal grille and a kickstand. Its bass reaches about 120Hz before falling 10dB, against 220Hz for the Lenovo 700 Ultraportable Bluetooth Speaker. It keeps a wired aux input, which the Lenovo 700 Ultraportable Bluetooth Speaker lacks. The catch: Huge lack of bass.
The Lenovo 700 Ultraportable Bluetooth Speaker is the lighter, tougher option. A very thin aluminum speaker about the size of a phone, with touch controls and voice assistant support. At 0.3 lbs (145 g) it weighs much less than the Harman Kardon Esquire Mini 2 at 0.6 lbs (250 g). It is rated IPX2, while the Harman Kardon Esquire Mini 2 has no water resistance. It plays in stereo from a single unit, unlike the Harman Kardon Esquire Mini 2. Watch for: Huge lack of bass, probably better off with your phone audio.
Buy the Harman Kardon Esquire Mini 2 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Tribit Stormbox Micro 2 instead.
