People spend hundreds or even thousands on these cables thinking they improve the sound quality. possible safety. So I took a bite. I replaced my lovely $10 cord with this one and I confess - I feel less distorted and feel better - I'm mostly writing a review because the seller was great. Although the product was new and worked well, Revain Prime abused the packaging - they put stickers all over the box and the box was difficult to handle. The seller gave me a good discount. Excellent seller.
