Ranked #30 of 263 in In-Ear Headphones - Tanchjim Soda: $309.99 Amazon eBay
Pros: Squig.link measurements, the median of 10 hobbyist samples, give it a preference score of 82, with bass within a decibel of target from 20 Hz and a gentle lift around 60 to 200 Hz for warmth. The one dynamic plus four balanced armature hybrid at 120 dB/Vrms needs very little power, so a phone is enough. It suits listeners who like a warm, bass forward balance without exaggeration.
Cons: The 3 to 6 kHz presence band sits nearly 3 dB under target, with a 3.8 dB dip near 5.6 kHz, so vocals and snare attack lose some bite, and the top octave rolls about 2 dB short, trimming airiness. Its average deviation of about 1.3 dB is less even than the higher rated Tin HiFi T7, which sells for less.

Ranked #64 of 263 in In-Ear Headphones - Tanchjim Ola Bass: $22.99 Amazon eBay
Pros: In the median of five squig.link measurements it scores 80.2 for preference, and its treble is remarkably even, with no peak larger than 1.6 dB or dip deeper than 1.9 dB between 1.5 and 12 kHz. A 2.1 dB bass lift gives the warm, punchy low end its name promises. At 126 dB/Vrms and 16 ohms it runs effortlessly from a phone, and the inline mic handles calls.
Cons: Sub-bass trails the midbass by about 3 dB, so the deepest rumble is lighter than the bass emphasis above it. Low mids sit about 1.1 dB above target, which can make dense mixes sound slightly thick.

Ranked #109 of 263 in In-Ear Headphones - 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.
