#153 ThieAudio Oracle Discontinued eBay
Newer model: the ThieAudio Oracle MKII, ranked higher, rated 4.5/5, released Sep 2022 (also discontinued). See every ThieAudio Oracle generation.
Pros: The median of 16 hobbyist measurements gives it a very good Harman preference score of 78 with a 1.62 dB spread. Upper treble lifts about 3.7 dB for extra air and sparkle. It uses 1 x 10mm dynamic + 2 x balanced armature + 2 x electrostatic.
Cons: Discontinued, so it is mainly found used. Presence sits about 3.9 dB low with a 5.4 dB dip near 4.9 kHz, so vocals and instruments lose some bite. Sub-bass is 2.6 dB short at 30 Hz, so deep bass lacks rumble.
