Virtually all headphones that terminate in a stereo 1/4" plug can be used with the S amp
Headphone Amplifier. This chart provides a partial listing of some of the more popular
models, along with their impedance and sensitivity ratings. As described on page 4 of this
manual, headphones with lower impedances (or higher sensitivity) will sound louder as
compared to other, higher impedance (or lower sensitivity) headphones at the same chan-
nel Volume setting. Samson Technologies has no connection with any of these manufac-
turers, nor do we endorse any particular models for use with the S amp. This is simply a
reference listing for your convenience. For more information about any of these head-
phones, contact the manufacturer directly.
