#186 Aurorus Audio Borealis: $899.99 Aurorus Audio $899.99 eBay
Pros: A broadly balanced tuning with a preference score of 76 against the Harman target.
Cons: About 7 dB less bass than the Harman target below 150 Hz, which can sound thin on pop, hip hop and electronic music. Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones. An uneven response, 2.7 dB standard deviation from target.
Is the Aurorus Audio Borealis right for you?
Buy it if
- you want the tuning most listeners prefer in blind tests out of the box (Harman score 76).
- you are sensitive to bright or sharp treble (treble sits 3.1 dB below target).
Skip it if
- you want more bass (about 7 dB below target).
- you need isolation or will use it in public: open-back headphones leak sound both ways.
- you want the best value: the higher-rated Sennheiser HD 550 costs about $700 less.

Frequency Response
How the Aurorus Audio Borealis measures across the audible range, against the Harman over-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 3 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 3 measurements from the squig.link databases of capraaudio, hadoe and listener. Thanks to each of them for publishing their work.
