This is an awesome setup and something that is going to last for a long time. There was no way to centre it properly due to the poor framing, therefore I was sad to think that I would have to put something else above my shelf. And this is how I ended up using and enjoying this product for the first few weeks, at least . I bought the MIDOLA Bluetooth headphones to replace wired headphones that I use at the gym. I first ordered a size 8 (my US size) for Nike is a EURO 39. It looks so much better than my old system. I also love that the heel collapses for quick on and off. They are sturdy and comfortable. Measure your waist Im a tiny person but my tummy was the problem needed more flatter belly so I got a large and it fits perfect! Funciona bien con el telefono como manos libres, intente usarlos con la computadora para conferencias en zoom pero el sonido fue muy malo, sin embargo para escuchar musica con la computadora no tube mayor problema.
