This is a huge problem. I?ve had them for about 3 months at this point. 5 or 9 and ordered the 9. nice quick scam. SOLO ME DECEPCIONO QUE NO ES DUAL SIM. It folds up nicely when retracted, and has a nice look to it, rather than having a cheesy, box-store kickstand look. I had to put both emitters at the same location to get it to work. 99, but do not have replacement rubbery ear pieces and are not packaged for individual sale. Si tienes la oportunidad de tener un servicio de Tidal, el plus de estos audífonos es increíble ya que la calidad de esta plataforma, puedes escucharlas en su formato más alto de grabación y simplemente se oye estupendo! If you?re flying a lot, or at a desk all day, these are a good fit (if you want excellent sound quality).
