#400 Kiwi Ears Forteza: $59.00 Amazon $59.00 eBay
Pros: The median of 16 hobbyist measurements gives it a solid Harman preference score of 71 with a 1.97 dB spread. Bass is lifted about 3.6 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. It uses 2 x 10mm dynamic + 1 x balanced armature with an easy 32 ohm load.
Cons: A 10.7 dB peak near 8.2 kHz can make cymbals and sibilance sound sharp.
