HP Poly CS540 Spare Earbuds and Earloops Kit – 86540-01, S/M/L Earloops + Foam Pad (85Q18AA)

The Poly CS540 Spare Earbuds and Earloops Kit (85Q18AA, part 86540-01) is the complete wearing comfort replacement kit for the CS540 convertible wireless headset. The kit includes small, medium, and large earloops plus a foam ear pad, covering all three in-ear and over-ear wearing configurations. When the original earloops wear out or are lost, this kit restores all available wearing options in a single purchase rather than requiring separate orders for each size.
