Astell & Kern PSF11 Layla 12 Drivers Per Side Universal Fit In-Ear Monitors

A member of the "Sirens Series" designed by Jerry Harvey of JH Audio in collaboration with Astell&Kern, the PSF11 Layla 12 Drivers Per Side Universal Fit In-Ear Monitors are inspired by the song "Layla" by Derek and the Dominos. The universal in-ear monitors use 12 drivers per side (4x low, 4x mid, 4x high) to deliver a frequency response of 10 to 23,000 Hz into a 20 ohm load with a sensitivity of 117 dB at 1 mW.
