Dobrý deň, prosím je možné doobjednať náhradné penové náušníky/krytky lebo sa mi jedna stratila, resp. neviem aký romer a kde hľadať aby pasovali. Ďakujem

Dobrý den, tohle teda ani neni dotaz. Také jsem tu hledal jak sluchátka spárovat. Viděl jsem tu odkaz na video a tak zkouknul asi 5 videí(v angličtině) k různým tipům sluchátek KOSS, ale se stejným ovladačem hlasitosti. Takže při zapínání sluchátek při párování se prostřední tlačítko musí podržet déle (asi 5vteřin) ne je jen zapnout. Pak pípnou trochu jinak a až pak se objeví na tlf., např. jako KOSS BT221i ;-)

nemohu najít dobu výdrže na nabití, neporadil by mi někdo prosím?

Dobrý den, je se slucháty dodávaná i nabíječka? Nikde tuto informaci nevidím. Příp. pokud není, jakou byste mi doporučili k zakoupení?

jak je nabíjet

Dobrý den, některá sluchátka mají plynulý náběh zvuku (Fade In), na začátku, nebo při přepínání mezi skladbami, a tento efekt nejde vypnout. V popisech to nebývá uvedeno. Nelíbi se mi to. Mají to tyhle sluchátka?

Jaký je výkon Bluetooth vysílače ve sluchátkách?

Jaký mají konektor?

Dobrý den, mají tato sluchátka doživotní záruku u KOSS? Děkuji.

Dobrý den, mají sluchátka: zvlášť tlačítko pro zapnutí/vypnutí sluchátek jako takových a zvlášť tlačítko jen pro zapnutí/vypnutí mikrofonu? Děkuji, Martin
