JBL Soundgear Sense vs Soundcore C40i by Anker
Quick take: The Soundcore C40i by Anker costs $15 less; the Soundcore C40i by Anker lasts longer per charge (7 hrs).
Which one to buy
These two open-ear designs suit different listeners. The JBL Soundgear Sense ($115) uses an earhook with an enormous 16.2mm driver. The Soundcore C40i ($100) is a clip-on cuff with a 12x17mm oval driver. Which one works for you depends mostly on two things: glasses, and how much you value bass over discretion.
On sound, the JBL has the stronger owner reputation. Its big drivers give the open-ear category something it usually lacks, real low-end punch, and the JBL app adds a 10-band EQ. The C40i sounds flat out of the box and needs a session in the Soundcore app before it sounds good. Even then, owners say its bass has a ceiling. The C40i makes up for that with discretion. Its directional driver keeps leakage modest enough for an office at sensible volume, while Soundgear Sense owners report being asked to turn down in libraries past half volume.
Fit is where they differ most. At nearly 13g per bud, the JBL's hooks take up the same space as glasses arms, and owners describe taking their glasses off, seating the buds and putting the glasses back on. The roughly 6g clip-on leaves your temples free. The JBL answers with the detachable neckband, which turns the buds into a lose-proof set for trail runs. The C40i runs large for a clip-on, though, and some smaller-eared owners get soreness on the ear edge after an hour.
The batteries are similar on paper, 6 hours (24 total) against 7 hours (21 total), though JBL testers often see about 8 hours. The JBL's 15-minute charge buys 4 hours. The JBL is rated IP54 against the C40i's IPX4, and the C40i uses physical buttons that don't misfire with sweaty fingers. JBL owners describe a muddy, fluctuating mic in noise, so it isn't the pair for important calls.

Soundcore C40i by Anker
Best if you wear glasses, want to try clip-ons without spending much, or need something discreet enough for an office.
