Microphone for my Bluetooth stereo

Hi there,

I'm just thinking which MIC I should buy out of these 2? Both are cheap but 1 is really cheap, I dont need a high quality one so 1 of these 2 should do.

I wont be using bluetooth much, but when I do use it I want my voice to be understandable to the person on the other end.

This cost £8, will it be better quality/clearer than the other?

This Cost £3 and if it's half decent I want this one

Ended up buying the cheaper 1, fingers crossed its half decent.
