Review: works as advertised - Good quality. A bit thick but otherwise really really good
Review: perfetti per cavi che hanno il jack ricurvo - avevo un cavo per cuffie professionali che era strutturato in modo che il cavo aveva il maschio del jack in uscita piegato di 90 gradi, peccato che così non potevo inserirlo nel cellulare perché con una cover molto fine non entrava il jack perfettamente, grazie a questi adattatori sono riuscito a inserirlo senza problemi, nessuna perdita di qualità del suono. Molto soddisfatto
