Cut the earbuds off, splice them into 1mm molex connectors, and plug them in where the speakers are currently mounted behind the ear piece foam. Love these ear buds. Yes I know they are slippers. I absolutely love this headphones. However it is smaller than I anticipated. Love these slippers so far! I can?t vouch for the older Mac laptops, but on my 2017 MacBook Pro (with thunderbolt) it works fine. Really like this shoe. Really disappointed as Chaco makes quality shoes. It didnt even get to us then, however; it sat at a shipping facility a few miles away from us from the 13th until the 22nd.
