Short answer: the 7Hz Timeless. It ranks #189 of 450 in-ear headphones by sound quality, rated 4.2/5, at $199.99; the 7Hz Timeless II ranks #288, rated 3.9/5, and costs $217.55, so there is little reason to consider the other one.
The 7Hz Timeless is the better-sounding choice. In oratory1990’s measurement it earns a preference score of 76 with a low 1.9 dB deviation from target, so the overall balance stays close to what most listeners prefer. The catch: A peak of about 8 dB near 11.9 kHz puts the air region almost 8 dB above target, which adds sparkle that some listeners will find splashy or fatiguing on bright recordings.
Buy the 7Hz Timeless. It is rated higher for sound quality than the 7Hz Timeless II and costs less, which makes it the one to get unless you need something the other one does better.

7Hz Timeless: $199.99 Linsoul eBay
Pros: In oratory1990’s measurement it earns a preference score of 76 with a low 1.9 dB deviation from target, so the overall balance stays close to what most listeners prefer. Sub-bass holds almost exactly on target down to 20 Hz, sitting only 0.3 dB low at 30 Hz, and the bass gets a mild 1.8 dB lift that adds warmth without muddying the mids. The 14.2mm planar driver is rated at 14.8 ohms and 104 dB, so a phone or small dongle drives it comfortably.
Cons: A peak of about 8 dB near 11.9 kHz puts the air region almost 8 dB above target, which adds sparkle that some listeners will find splashy or fatiguing on bright recordings. The presence band sits 3.6 dB low with a 5 dB dip near 4.2 kHz, so vocals and guitars can lose a little bite and edge.
