I haven’t used them for music so I can’t speak to the music control on the other ear. She loved the color and they fit as expected. It was too small. the board lights up briefly, gives the fan a spin then immediately dies. Theres no flaws with the shoes, the white material could be taken for cheap but I actually like it because its soft and comfortable. Better than expected for the price point, and I was very nervous shopping online for shoes. It helps to really sweat more around waist area and feels so good to wear even for long time. The bass is prominent, and will be felt. Yo personalmente los he comprado por 128 euros en una bajada de precio que hubo durante un par de días. It has a key ring connector.
