#237 HiBy Crystal 6: $459.00 HiFiGo eBay
Pros: A lively V-shaped tuning with about 3.7 dB of extra bass and a treble lift of 5 to 6 dB above 6 kHz, which gives drums punch and cymbals plenty of sparkle. Sub-bass stays within 6 dB of target down to 20 Hz. Six balanced armatures at 14 ohms and 107 dB/mW run fine from a phone. It matches the rating of the Shanling ME700 for less money.
Cons: Squig.link measurements show a 9.9 dB peak near 7.9 kHz, so sibilance and hi-hats can turn sharp and fatiguing at higher volumes. A 3.7 dB lift from 200 Hz to 1 kHz thickens male vocals and lower instruments. The Etymotic ER4XR earns the same rating for considerably less.
