1.Dinamic mics are good
2.Carddiod the best.
Beta 54 Super carddiod headset mic was recomended . Beta 54 Headworn Microphone gives full,clear and natural vocal sound. WBH 54 is the same in wireless version (USA)
Kuguar,
Microphone choice is a very personal thing, depending on your taste in sound, what you intend to use it for, and the technique you use when performing/recording. I assume you want a microphone to record your voice.
First of all, I have to say that I
like the sound of your vocal recordings. The microphone you are using now may be all you need.
A good general approach is to purchase a quality microphone from any reputable manufacturer, and then
learn how to use it to get the sound
you want. Almost any good quality microphone will give you excellent results, once you have experimented with it and found how it responds in various situations.
If you were to buy a solid, all-purpose, hand-held, dynamic, cardioid microphone from a quality manufacturer, that would be excellent. The Shure SM57 is an example - a very old design, strong, reliable, inexpensive.
The only problem with a headset microphone is that they are not as strongly built as a hand-held type, and would tend to break easily. Plus, they are not good for recording instruments, or a group of musicians, if you ever wanted to.
I hope this helps,
Oren.
