The problem with cheap Chinese mics are handling noise & dodgy XLR sockets.
I've got 3 KAM mics that was @ £30 each & wouldn't give em to someone I didn't like, let alone suggest buying them.
I'm looking for some decent mics & see that Shure make a few around the £50 mark, such as the SM48, PG48 & PG58.
Anyone got experience of these?
