Short answer: the Noxgear 39g, if you are buying new, though neither ranks well in its class. The Lenovo 700 Ultraportable Bluetooth Speaker ranks higher than it (#46 vs #48 of 49 small speakers, 2.3/5 vs 2.2/5) but is discontinued, so only consider it used; the Noxgear 39g is still sold new at $69.95. Both are rated below 3.0/5 among the 49 small speakers; for better sound, the Tribit Stormbox Micro 2 ranks #1 at $49.99.
What the Lenovo 700 Ultraportable Bluetooth Speaker does well: Very thin profile: about 11mm, similar footprint to a phone. Watch for: Huge lack of bass, probably better off with your phone audio.
What the Noxgear 39g does well: Magnetic clip attaches through a shirt/jacket without pins. The catch: It sounds worse than a clock radio with the worst bass of any speaker.
Buy the Noxgear 39g, since the Lenovo 700 Ultraportable Bluetooth Speaker is discontinued and only worth hunting down used.
There is a real gap in water resistance: the Noxgear 39g at IPX7 (brief submersion) against the Lenovo 700 Ultraportable Bluetooth Speaker, which has IPX2 (light drips).
