Hello all, Haven't used these in past half year so I am looking to sell them or downgrade. They are in perfect working condition and cosmetically in perfect condition as well thanks to Noble's fantastic build quality. Still eligible for reshell at Noble's Audio since these were built before 2017 of this year (Serial # 4). Noble Audio's OTS is $400. I am not looking to negotiate on price if selling so price is firm. As for trades I am mostly interested lower end IEMs + cash on your end or HD600's + cash on your end. Let me know if you have anymore questions. Thanks.
