Ortofon O-One

The Ortofon headphone O-One produces balanced, reference-grade signal output, worthy of use in critical listening situations. The O-One, unlike other closed-back designs, was engineered to provide a precise representation of sound without coloration or inaccuracies. This design offers audio professionals, musicians, and discerning listeners a transparent window into sonic purity and is revealing of not only the details and elements which comprise the signal but also any inadequacies or inconsistencies.

The O-One headphones are not only built to withstand repeated use and travel, but they are also designed with optimal impedance and sensitivity to allow for use with a wide array of equipment. Since O-Ones can be used effectively with virtually any source equipment, even auditioning for reference on personal music players and other consumer equipment is easy and requires no additional amplification.
