This system was purchased about a year ago and has about 15 hours on it. I only took it on 3 trips so it's in perfect condition.
I have custom molded IEM sleeves that I used with this system, so the box was opened then the amp and cable was taken out, and that's it. Everything else was left as is, including all the sleeves that are unused. Nothing's open so there's no difference then buying new.
I also purchased a pure silver USB cable to connect to my phone, which is included. Picture of it is below.

This price includes all fees and expedited shipping.
