Short answer: the Tin HiFi P1 Max. Both are rated 3.6/5 for sound quality (#342 and #345 of 450 in-ear headphones), and the Tin HiFi P1 Max costs $219 against $249 for the 7Hz Eternal, so with nothing between them on sound quality, price settles it.
What the 7Hz Eternal does well: Crinacle’s measurement gives it a preference score of 69, and squig.link measurements show bass, mids and upper mids all within about 1 dB of target, so voices and instruments sound natural. The tradeoff: Treble above 6 kHz drops 3 to 4 dB below target with an 8.7 dB dip near 10.6 kHz, so cymbals lack sparkle and detail sounds dim.
What the Tin HiFi P1 Max does well: Its 14.2 mm planar magnetic driver earns a preference score of 69 in crinacle’s measurement, and across 12 hobbyist measurements on squig.link bass, low mids and treble from 6 to 10 kHz all stay within about a decibel of target. The tradeoff: Hobbyist measurements show the presence region about 5.6 dB below target with a 6.6 dB dip near 3.6 kHz, which pushes vocals and lead instruments back, while a 4.8 dB peak near 8.1 kHz can make sibilants stand out.
Buy the Tin HiFi P1 Max. Both are rated the same for sound quality, and it costs $30 less than the 7Hz Eternal.

The Two Headphones In Full
7Hz Eternal: $249.00 Linsoul eBay
Pros: Crinacle’s measurement gives it a preference score of 69, and squig.link measurements show bass, mids and upper mids all within about 1 dB of target, so voices and instruments sound natural. Treble rolls off gently, giving a smooth, unfatiguing sound for warm-leaning listeners. A 30 ohm, 109 dB/1kHz rating means a phone drives it easily, and each earbud weighs 6 g.
Cons: Treble above 6 kHz drops 3 to 4 dB below target with an 8.7 dB dip near 10.6 kHz, so cymbals lack sparkle and detail sounds dim. The IKKO OH10 and Etymotic ER2XR are rated higher for less money.

Tin HiFi P1 Max: $219.00 Amazon eBay
Pros: Its 14.2 mm planar magnetic driver earns a preference score of 69 in crinacle’s measurement, and across 12 hobbyist measurements on squig.link bass, low mids and treble from 6 to 10 kHz all stay within about a decibel of target. That gives instruments a clean, uncolored foundation. It rates higher than the pricier FiiO FH7S.
Cons: Hobbyist measurements show the presence region about 5.6 dB below target with a 6.6 dB dip near 3.6 kHz, which pushes vocals and lead instruments back, while a 4.8 dB peak near 8.1 kHz can make sibilants stand out. Its 98 dB sensitivity is low for an in-ear, so it needs more volume than most. The cheaper Etymotic ER2XR and Samsung Galaxy Buds2 both rate higher.
