Short answer: the JBL Live 300TWS. It ranks #789 of 1369 in-ear headphones by sound quality, rated 3.5/5, at $69.99; the Kinera Idun 2.0 ranks #864, rated 3.4/5, at $69. Close enough in price that the sound-quality gap is the deciding factor.
What the JBL Live 300TWS does well: It uses 1 x 5.6mm dynamic with an easy 16 ohm load. Watch for: Its 2.30 dB spread is less even than the best measured sets.
Why pick the Kinera Idun 2.0: A broadly balanced tuning with a preference score of 67 against the Harman target. The catch: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the JBL Live 300TWS. It is rated higher for sound quality, and saving $0.99 with the Kinera Idun 2.0 does not make up for the sound-quality gap.
