Ludos would you ever make a wireless pair of these. I have other Chaco styles which are fine. I actually stand straighter with shoes that have a bit of a lift, and these seem to have just the right amount. In terms of sound, using 4. Ok, not super bright. Will definitely order again. No ajustan al oído, se chispan y para llamadas la calidad de audio en el micrófono es mala. I only needed one but quickly found uses for the other ones. These had sort of round spikes on them so that they spike you as you walk along! "Fancy slippers" was his response when he put them on.
