Short answer: the Hisenior Mega5P Ultra. It ranks #537 of 1291 in-ear headphones by sound quality, rated 3.9/5, at $299; the Fostex TM2 ranks #588, rated 3.8/5, and costs $299.99, which makes this an easy call rather than a real tradeoff.
What the Hisenior Mega5P Ultra does well: A broadly balanced tuning with a preference score of 72 against the Harman target. The tradeoff: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
The case for the Fostex TM2: Crinacle’s measurement gives it a solid Harman preference score of 71 with a 2.35 dB spread. The tradeoff: Its 2.35 dB spread is less even than the best measured sets.
Buy the Hisenior Mega5P Ultra. It is rated higher for sound quality than the Fostex TM2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
