Short answer: the Noble Audio Tux 5, though neither ranks well in its class. Both are rated 2.1/5 for sound quality (#1140 and #1146 of 1291 in-ear headphones), and the Noble Audio Tux 5 costs $1,300 against $1,675 for the Nightjar Singularity, so with nothing between them on sound quality, price settles it. Both are rated below 3.0/5 among the 1291 in-ear headphones, so if sound quality matters, consider the ThieAudio Monarch MKIII instead, ranked #1 at $999.
The case for the Nightjar Singularity: About 5 dB more bass than the Harman target below 150 Hz, for listeners who want a fuller low end. Watch for: Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
The case for the Noble Audio Tux 5: It uses 1 x 10mm dynamic + 4 x balanced armature. The tradeoff: A Harman score of 51 places it in the lower part of the in-ear rankings.
Buy the Noble Audio Tux 5. Both are rated the same for sound quality, and it costs $375 less than the Nightjar Singularity.
