#108 HIFIMAN RE600S: $83.29 Amazon eBay
Pros: At 16 ohms and 102 dB/mW a phone drives it easily, and the single 8.5mm dynamic driver keeps the design simple. Listeners who want a relaxed sound with no treble glare may find its subdued highs inoffensive.
Cons: In oratory1990’s measurement bass falls 6 dB below target by 95 Hz and is about 11 dB down at 30 Hz, so music sounds thin, while presence and air sit roughly 10 to 12 dB below target with a 13.4 dB dip near 11.9 kHz. That leaves voices and cymbals dull, and a preference score of 43 is among the lowest for in-ears. The BASN Bmaster and KZ ASX both rate higher.
