2008 design. By Vers Audio. Enjoy the warm, natural sound of Vers wherever you go. Vers 1E headphones are individually crafted with sustainably sourced hardwoods and Bamboo, and produce that familiar, natural sound quality Vers has become known for. The low-profile integrated microphone with mute and play/pause control makes it a perfect solution for 30-pin (pre Lightning) iPhone and iPod* or any device with a 3.5 mm headphone jack. The in-ear passive noise cancellation design blocks 90% of the surrounding sound, assuring an ideal acoustic experience in any environment. As with all of their wood accessories, for every tree used in production, Vers plants 100 more trees through their long-time partnership with the Arbor Day Foundation. The 1E Earphones feature a hand-crafted U.S. hardwood or Bamboo shell, in-ear passive sound isolation design, and integrated microphone with mute and play/pause control, a precision-tuned port for full bass response, 10 mm diameter driver, 18 Hz - 20 kHz range, 114 ±3dB sensitivity, 32 Ω impedance and PVC free & RohS compliant. Includes 1E sound isolation earphones with integrated mic, S/M/L interchangeable earcaps and a felt-lined recycled metal carrying case.
