Jaký je rozdíl mezi těmito sluchátky za 899,-kč a ostatními Kossáky v cenách cca 1100-1800,-kč? Když jsem je dal do stovnávače zboží, tak mezi nimi kromě barvy nebyl rozdíl, ale přijde mi divné, že by to byl důvod rozdílu, který je v cenách...

Dobrý deň, chcem sa opýtať, že či pri kúpe použitých sluchátok Koss porta pro za 23€ budú aj tieto mať kód na uplatnenie doživotnej záruky u výrobcu? Ďakujem za odpoveď.

Když to je na těch 24 mesícu to známená že když si na to dám doživotní záruku od koss přes ten kód co je v balení tak to bude platit jen na 24 mesíců ? Nebo ta doživotní nebo 24 mesiční je jen záležitost záruky od alzy ?
