#64 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.
