#270 DUNU SA6 Discontinued eBay
Pros: The original six balanced armature SA6, which measures better across 21 measurements (score 76) than the DUNU SA6 MK2 that replaced it.
Cons: Discontinued, so it is mainly found used. Bass sits about 2 dB and treble about 3.6 dB below target, a mid-forward balance, and sub-bass falls 2.5 dB short at 30 Hz.
Is the DUNU SA6 right for you?
Buy it if

- you are sensitive to bright or sharp treble (treble sits 3.6 dB below target).
Skip it if
- you want to buy it new: it is discontinued.

- Reviews, Comparisons and Sound Samples
Frequency Response
How the DUNU SA6 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 the median of 21 independent measurements, so one odd sample or rig cannot skew it, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: median of 21 measurements from the squig.link databases of aden, adri-n, aftersound, audioamigo, bukanaudiophile, dchpgall, dentreviews, flare, hbb, iemocean, koi, mmagtech, musicafe, nymz, precog, pw, sl0the, soundignity, superreview, therollo9 and timmyv.
