ORTOFON O-One Headphones


The Ortofon O-One is an excellent device for studio sessions and mixing

The Ortofon 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.

Included with the O-Ones are two sets of earcups (one of each pair, leather and velour) for long term wearing comfort.
