Looking to sell my JAR600 in excellent condition. I have received these from Jupiter audio research in early 2022 after 7-8 months wait time. If you had enjoyed the regular HD600s, you'll definitely like these as the mod have improved the SQ across the boards. I have asked JAR to replace the earpads as well, so they are in like-new condition as I've only put maybe 15 hours in them. I think JAR mentioned he had mod the ear pads as well but not sure about the details on that one. I will also include a brand new Sennheiser headband pad to replace the old deflated one. I think these are silver screens ones made somewhere in the late 2000s. Mods alone cost $550 plus shipping there and back from overseas. Asking $600usd + shipping. I will cover the 4.5% pp fee. Let me know if you're interested! Thanks for looking.
