There's something really strange about the audio, true. No, it's not, for a Polish ear the German "ich" sounds like "iś", so that's not even remotely close.
Many pronunciation guides compare the h = ch (same sound, just an orthography issue) sound in Polish to the sound in the original, Scottish pronunciation of Loch Ness.
Well, if you know IPA, that's [ix]. The x sound (do not confuse it with what the letter x sounds like) isn't really used in English, apart from Scotland.
But if you have problems with that, I guess better just go with "h" like in "hat".
