#94 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.
