#1108 Nightjar Singularity: $1,300 eBay
Pros: About 5 dB more bass than the Harman target below 150 Hz, for listeners who want a fuller low end.
Cons: Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones. Measures far from the Harman target (preference score 51), so most listeners will hear it as colored; EQ can correct much of this.
Is the Nightjar Singularity right for you?
Buy it if
- you like extra bass (about +5 dB below 150 Hz versus the target).
- you are sensitive to bright or sharp treble (treble sits 2.7 dB below target).
- you want sub-bass rumble that reaches down to 20 Hz.
- you are happy to use EQ: our preset lifts its Harman match by about 39 points.
Skip it if
- you want a neutral sound without EQ (Harman score 51).
- you want the best value: the higher-rated EPZ G10 costs about $1,276 less.

Frequency Response
How the Nightjar Singularity 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 10 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 10 measurements from the squig.link databases of aden, banzai1122, freeryder05, hadoe, harutohiroki, listener, pw, ragnarok, sl0the and smirk. Thanks to each of them for publishing their work.
