Had some free time to dedicate to "maintenance" of the LCD3 today. Conditioned the stock leather headband before returning it to the storage case now that I am using the Carbon Fiber upgraded headband. After that is was on to massaging the leather ear cups to feed and condition the supple leather with Audeze Leather Conditioner. Buffing the leather and wiping the headphone down with a microfiber cloth resulted in spotless, shiny and gorgeous wood trim and well fed and conditioned leather ear cups.
Then it was on to cleaning and polishing the silver 1/4 TRS jack of the Wireworld Platinum Cable with the Wireworld Jewelry cleaning cloth.
Oh, of course they sounded better than ever after the maintenance routine.
Don't forget to condition your Audeze and other headphones on a regular basis to maintain and preserve the leather.
