#135 Final Audio A6000: $479 eBay
Pros: A single 6 mm dynamic IEM with a preference score of 80 and full bass down to 20 Hz with a slight lift. The midrange is close to target, and the titanium coated shells are light at 24 g.
Cons: Treble from 5 to 8 kHz runs 4.1 dB hot with an 8.8 dB peak near 8.2 kHz, so it can sound bright and sibilant. It is sold out after listing at $479, and the score rests on a single measurement.
Is the Final Audio A6000 right for you?
Buy it if
- you want the tuning most listeners prefer in blind tests out of the box (Harman score 80).
- you want sub-bass rumble that reaches down to 20 Hz.
Skip it if
- you are treble-sensitive (treble sits about 3.7 dB above target).
- you want the best value: the higher-rated QCY HT05 MeloBuds ANC costs about $445 less.

Frequency Response
How the Final Audio A6000 measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is a single measurement, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: a single measurement from the squig.link database of hu-fi. Thanks to them for publishing their work.
