I need a recommendation on a good headset mic for an arranger keyboard.
I've been using a Radioshack headset mic with my PSR 740. The three good things about it are that it's very comfortable, has a three year extended warranty, and best of all, comes with a battery operated preamp that boosts the level. The downside is that it delivers somewhat mediocre audio quality. I mean, I'm very popular at my gigs, but when I record what comes out, I'm not very impressed.
For those who have never used a headset mic with an arranger keyboard, they have three big advantages:
1. Less gear to carry
2. You can look at the audience all around and still sing
3. You can look at the display and buttons on your keyboard and still sing.
I was wondering if someone could recommend a great headset mic that is suitable for an arranger keyboard? I've seen models by Nady, Shure, Crown, and Audio Technica. I see that there are a couple of condenser mics. One by Crown, for example, comes with a battery pack so you don't need phantom power. I wonder if anyone has had excellent luck with using one of these headset mics with their arranger.

Thank you,

Larry
