(You will need two 15/16” wrenches). An unexpected plus is, when I had to build a factory-direct bike, I needed something to hold the fork and handlebars to the body while I installed some parts, so they wouldnt just fall freely/bend the cables. Especially considering the price range. Letzteres geht übrigens präzise und bleibt, einmal eingestellt, fix in Position. Well, news flash, they are cheap. I sincerely thought they would stretch slightly after wearing - they are supposed to be leather after all. Just below the middle of the inside of the earbud is where the earpiece extrudes from the main unit. I wanted to like them better than the Monoprice set but honestly the Monoprice is so close its very subjective. These are premo sandals. Unfortunately, it’s been almost exactly two months of owning this pair and they have broken.
