#1110 Roseselsa Aurora Ultra: $39.99 Amazon $39.99 eBay
Pros: A dynamic plus planar hybrid at about $40, measured by 12 reviewers, whose bass and midrange stay within 3 dB of target with sub bass to 20 Hz. 115 dB/mW sensitivity makes it loud from any phone or dongle.
Cons: A deep dip of about 9 dB from 6.7 to 7.1 kHz followed by a 5.5 dB peak near 11.5 kHz makes the treble uneven, so detail can sound veiled with an odd sparkle on top. The EPZ Q1 Pro scores far higher at a similar price.

Buy it if
- you are sensitive to bright or sharp treble (treble sits 4.0 dB below target).

Skip it if
- you want the best value: the higher-rated EPZ G10 costs about $16 less.

Frequency Response
How the Roseselsa Aurora Ultra 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 12 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 12 measurements from the squig.link databases of atechreviews, audioamigo, elrics, hobbytalk, jaytiss, lumerion, obodio, practiphile, soundcheck39, theaudiostore, tonedeafmonk and treblewellxtended. Thanks to each of them for publishing their work.
