#85 Tanchjim Oxygen: $279.99 Apos Audio eBay
Pros: Crinacle’s measurement gives it a preference score of 77, and across 22 hobbyist measurements its sub-bass lands right on target at 30 Hz, giving full, extended low end from a single 9.2 mm dynamic driver. Bass from 60 to 200 Hz sits about 1.9 dB above target for a warm, punchy balance that bass lovers will enjoy. At 32 ohms and 110 dB sensitivity it plays loud from a phone.
Cons: The presence band from 3 to 6 kHz falls about 2.2 dB short and a 4.7 dB dip near 10 kHz dulls cymbal edges and sibilants, in squig.link measurements. The response is less even than the best, at 2.08 dB standard deviation. The Etymotic EVO and Moondrop Blessing earn higher ratings for a little more money.
