#524 Grado GT220 TWS Discontinued eBay
Pros: Bass is lifted about 4.5 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 8mm dynamic with an easy 32 ohm load.
Cons: Discontinued, so it is mainly found used. A 6.4 dB peak near 11.8 kHz can make cymbals and sibilance sound sharp. The 4.5 dB bass lift can sound boomy and mask midrange detail.
