I have a pair of MrSpeakers Aeons for sale in excellent/like-new condition. I just examined these closely, and I can't find a single blemish on them. I'm the original owner. Everything is included - the case, box, certificate of authenticity and the invoice from MrSpeakers. I'll cover USPS priority insured shipping to the US and PayPal fees. Alternatively, I can use UPS if you prefer. These are the best headphones I've ever owned. I'm only selling them because I'm not using them enough and have been listening to my speakers more often. Thanks for checking out my ad.
