### ⭐ Review
*by M***S on 22 July 2020*

No me ha servido para nada. Tras leer las opiniones de otros compradores, unas positivas y otras no, me aventuré a comprarlo. Para lo que yo he intentado no sirve. Conectarlo al móvil por Jack y a este cable un Jabra de diadema (RJ11). Se escucha pero no me escuchan y solo oyen ruidos. No sé si la experiencia le servirá a alguien, pero ahí la dejo.
