    Ecouteurs de qualité dans tous les para-
    mètres. très confortable dans l'oreille. c'est
    super. les basses sonnent merveilleux et lumi-
    neux. l'effet stéréo est bon. je le recommande.
    merci au fabricant et au vendeur. oui, le
    commutateur et le microphone sont faits très
    soigneusement de bon plastique et semblent
    robustes et fiables, le son diminue en
    appuyant sur le bouton, et deux pressions et la
    piste changent. je suis très content de l'achat.
