Short answer: the Noxgear 0.1 lbs (39 g), if you are buying new, though neither ranks well in its class. The Lenovo 700 Ultraportable Bluetooth Speaker ranks higher than it (#60 vs #62 of [63 small speakers](/portable/small/#noxgear-0.1 lbs (39 g)), 2.3/5 vs 2.2/5) but is discontinued, so only consider it used; the Noxgear 0.1 lbs (39 g) is still sold new at $69.95. 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 Lenovo 700 Ultraportable Bluetooth Speaker is the deeper-bass option. A very thin aluminum speaker about the size of a phone, with touch controls and voice assistant support. Its bass reaches about 220Hz before falling 10dB, against 300Hz for the Noxgear 0.1 lbs (39 g). It plays in stereo from a single unit, unlike the Noxgear 0.1 lbs (39 g). Watch for: Huge lack of bass, probably better off with your phone audio.
The Noxgear 0.1 lbs (39 g) is the lighter, tougher choice. An extremely light speaker that clips magnetically to a shirt, with a safety light for runners in low light. At 0.1 lbs (39 g) it weighs much less than the Lenovo 700 Ultraportable Bluetooth Speaker at 0.3 lbs (145 g). It is rated IPX7 against IPX2 for the Lenovo 700 Ultraportable Bluetooth Speaker. The tradeoff: It sounds worse than a clock radio with the worst bass of any speaker.
Buy the Noxgear 0.1 lbs (39 g), since the Lenovo 700 Ultraportable Bluetooth Speaker is discontinued and only worth hunting down used.
