Lezi zingcingo zisetshenziswa kakhuluukuxhumana kwangaphandlengezici ezingangeni manzi nezivikela isimo sezulu. Ngezingcingo zezimboni zangaphandle, singakunikeza ezifanelanayoama-handset anezinto ze-Cheimei ABS ezivunyiwe yi-UL,Izinto ze-PC ze-Lexan ezilwa ne-UV, izinto ezigcwele i-carbon kanye nezinto ezimelana nomlilo ukuze kuhlangatshezwane nesidingo semakethe esihlukene. Siphinde sibe nemakrofoni nezipikha zohlobo oluhlukile, njengesipikha sokusiza ukuzwa, isipikha esinamandla kakhulu kanye nesipikha esivamile esiguquguqukayo esinokumelana okuhlukile; Kumakrofoni, sinemakrofoni yohlobo lwe-electret, uhlobo oluguquguqukayo, olulingana ne-carbon kanye nokunciphisa umsindo wefayela elihlukile.
