I am not a singer, but then i own a pa4x, so i must try the VH for sure... anyone got a good advice for a cheep headset microphone.... nothing fancy or wireless, just a basic microphone...

I have no clue at all about microphones...

I have a Shure WH30 that works quite well and is inexpensive. Be sure to get the right (XLR) connector.
I don't use it much, but when I have, it sounded really good.

Hmmmm ... $3000 keyboard with the best harmonizer in the biz - don't use a cheap mic! You can get lots of good gear for very modest prices. Don't skimp on the mic - it's the same premise as in many computer actions:
Garbage IN - Garbage OUT.

Get a good mic

While i do agree with your logic... i am not going to spend a whole lot of money for something that i plan to use just a few times.. and yes there is cheep, as in not costing a fortune, as there is cheep as allmost a free give away...

Sounds like something that would fit my bill, sadly its no longer available in europe..

How much are willing to spend??

I was hoping to keep it under €100

Bachus, I will make you a great deal, one that I believe you will never regret, but it will cost you $150 US plus shipping. I have three Crown CM311-A headset mics, and I have retired. I have one that has never been used, other than to make sure it works. This, IMO, is one of the best headset mics ever produced and provides the highest quality vocals with incredible feedback rejection. The mic sells online for $419 and it is rare to see it priced lower.

Let me know if you are interested,

Now that's a deal. If I didn't have two Sennheisers, I would grab it.

Gary if the mic is still available I would like to buy it.

How’s the health going?

John, I'm still on the mend, slowly but surely coming along.

I gave Bachus the first shot at it, but if he doesn't want it, it's yours.

Bachus, you asked for it. Here we go.
Pyle-Pro PMEM1 Headworn Omni-Directional Microphone (3.5mm / 1/4'')
I bought mine for around $12 USD.

Read all the positive reviews. One verifed buyer on Amazon says,

"I must say that the technical spec's on this unit are about the same as, if not identical to, that of the "Countryman" or "Audio Technica" units costing upwards of $300 (which I have used many times), and to be honest I've not yet noticed any significant difference, other than the fact that it cost about 5% or less, of the price of the "allegedly" better brands. It has worked just fine for both speaking and singing, and with none of the undesirable noises and hypersensitivities that I've experienced from other products".

I thought I was buying one to use in the rains as a backup so to speak but I was pleasntly surprised to find out that this mic sounds as good, if not better than a couple of much more expensive headset mics that I have. I liked it so much that I bought two different types of connectors to use with my wireless systems. It seems that this particular model will fit your Korg PA4x with the 1/4 adapter included with the mic.

Still, if one is looking for a headset mic with handheld mic quality, the CMA311 seems to be the best option.
