#690 64 Audio Tia Fourte eBay
Pros: Lower mids sit within about 0.9 dB of target, keeping voices and guitars natural. It uses 1 x dynamic + 3 x balanced armature (tia) with an easy 10 ohm load.
Cons: Presence sits about 7.1 dB low with a 10.9 dB dip near 3.5 kHz, so vocals and instruments lose some bite. A 5.9 dB peak near 10.7 kHz can make cymbals and sibilance sound sharp. A Harman score of 59 places it in the lower part of the in-ear rankings.
