Crystal Cable Duet Series
Headphone and portable applications place unique demands on cable design and construction. Not only do they present mechanical challenges, both in terms of noise performance, mechanical stability and longevity but the rapidly advancing headphone performance has created one of the most sonically exacting markets.
