Nice and long so won?t need to be stretched either, thus enhancing their lifespan. Wichtig ist allerdings zu hervorheben dass im klassichen Bluetooth Betrieb kein Multitasking wie beim 20K möglich ist. So I?ll be contacting them to see if I can get replacements for the ones that were already broken upon arrival other than that I highly suggest these ! The shoes are super, super comfortable! Highs and mids are good and when in stereo mode paired with another XB12 the overall sound is much better. Exceptional quality, just a good hanging out kicking back flip flop. Under neath where the bottles sit is a metal mesh box that holds corks. I mostly listen to orchestral, choral, or solo music. I bought these in black and tan. First slipper ripped on top.
