Don't take too long, professional headphones attract a daily fee of 150/= the longer they stay uncollected at customs. So head there soonest and know what taxes + fees (if any) that you could be up against.

What do u think Vallerrie was it worth ordering the shoes ifwhat they charged is above 30%?? Again where can one get thet tarff they are charging for various items...was thinking of importing mobile accessories from middle east but am afraid of the tax....i dont know how much they\ll charge???

The tariff is somewhere online, just Google 'Kenya import duty tariff' or something like that.
If they are things you absolutely have to get and there is no cheaper option locally then go ahead.
Tax is alot but not that insane an amount.
