#879 Klipsch R6 II eBay
Pros: Bass is lifted about 5.5 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Lower mids sit within about 0.8 dB of target, keeping voices and guitars natural. It uses 1 x 6.5mm dynamic with an easy 18 ohm load.
Cons: Presence sits about 6.3 dB low with an 8.3 dB dip near 7.2 kHz, so vocals and instruments lose some bite. The 5.5 dB bass lift can sound boomy and mask midrange detail. A Harman score of 33 places it in the lower part of the in-ear rankings.
