I purchased a great 3rd-party band that has SS adapters that are copies of the Apple OEM SS adapters. Generally very close, but the little black rubber pads on either side of the metal "pin" that clicks into place are made of much softer material (soft rubber) than the OEM adapter (seems like plastic). Anyway, after not much use, the rubber pads have started to rip and tear a bit. Beyond tightening the fit a bit and perhaps preventing the adapter from making a clicking noise if there's a little play, does anyone have any idea what these rubber pads do? Are they even necessary? Many thanks in advance.
