Excellent condition and sound quality, KingSound KS-H3 electrostatic headphones and companion M-20 OTL Tube headphone amp. Step up to the world of electrostatic headphones driven by a very fine tube amplifier. These phones are fast, detailed, and very musical.The KingSound M-20 amp will also drive Stax Pro model headphones for those of you who might own them. I also have a HiFiMAN EF-5 tube hybrid headphone amplifier for $295 if you need a sweet sounding tube headphone amp to drive standard dynamic headphones. These phones have only been used a handful of times since I mainly listen to speakers. These are like new and I have the original shipping boxes and packing.
