Short answer: a tie on sound quality. Both are rated 4.4/5 (#94 and #121 of 450 in-ear headphones) at nearly the same price ($99 vs $99.99), so choose on features and fit.
What the 7Hz Salnotes Dioko does well: A preference score of 79 in oratory1990’s measurement, with bass and mids from 20 Hz to 3 kHz held within about 1.4 dB of target, so the low end is full and extends deep. The catch: Air above 10 kHz rises 7.1 dB over target with a 5.6 dB peak near 11.9 kHz, which can make cymbals and hi-hats sound splashy.
Buy the 7Hz Salnotes Dioko or the Oriveti Bleqk Dynabird on features: they are rated the same for sound quality at close to the same price.

The Two Headphones In Full
7Hz Salnotes Dioko: $99.00 Linsoul eBay
Pros: A preference score of 79 in oratory1990’s measurement, with bass and mids from 20 Hz to 3 kHz held within about 1.4 dB of target, so the low end is full and extends deep. The 14.6 mm planar magnetic driver and 16 ohm impedance give an unusual driver type at a modest price. It rates on par with the Sennheiser IE 200.
Cons: Air above 10 kHz rises 7.1 dB over target with a 5.6 dB peak near 11.9 kHz, which can make cymbals and hi-hats sound splashy. A 6.6 dB dip near 3.8 kHz pulls vocals back. The Truthear x Crinacle Zero RED costs less and earns a much higher rating.
