Here are some excellent quality concert recording microphones. I've been building these for the past few years and now am offering them on ebay. Past buyers have been flipping out over the sound quality, in fact I'll guarantee them to sound better than any other microphone that sells for less than $199! How's that for standing by my word?
Mics like this are known as binaural microphones and are ideally suited for stealth taping at concerts. I have been hand building these microphones for years for many tapers around the world and their sonic quality speaks for itself. My previous company, which I sold after 27 years, specialized in electronic measurement and test, so don't think that I don't know what I'm doing! I purchase the microphone elements direct from Japan, test each one and the grade-offs are sold to hobbyists.
So, what the heck is a binaural microphone? Like your ears, a binaural mic hears what you hear and when played back through a high quality system, accurately captures what you heard at the concert. The stereo and imaging effect is startling, very clear and transparent - provided that the recording and playback gear is of good quality. This fact also makes them ideal for conference or seminar recording since the stereo imaging will allow you to easily hear just as you were sitting there.
Ideally the microphone element should be very low mass (for best transient response) yet mechanically solid (for resonance free response). The electret condensor element used in these mics meets these requirements admirably. However, normal electret microphones do not and thus the constrained, boomy, harsh sound we've all heard from bootleg recordings made with normal microphones.
Included is a rugged die cast battery box which holds a battery (duh!) and a filtering system that rolls-off the low end to compensate for the boosted bass that is found in most live concerts. There is a small switch which selects two different bass roll off points - 30Hz and 150Hz. These frequencies are ideal for most venues and styles of music. Use 150Hz at rock and pop concerts and 30Hz for classical or jazz. You can hear if the sound is 'boomy' at the venue and change accordingly. The battery box is important since it powers the microphone elements allowing for much improved headroom and overload characteristics - if these mics overload, then your eardrums will be bleeding long before that! The battery is a regular 9 volt type and will last hundreds and hundreds of hours, the mics automatically turn on when their plug is inserted.
The microphones have a silky smooth response from approximately 30 Hz through 20 KHz (remember we roll-off the low end) and are quiet - in fact they are below the noise floor of any recording device you'll be using.
I have a very supple four foot long cord on the mics, allowing you to hide the mics on an eyeglass frame, hat or even in your hair! Molded rubber strain relief's on each mic protect the delicate element. A short connector cord also comes with the set to connect from battery box to the recorder. Hey, I even give you a battery too!
The folks I have sold these to in the past have been raving, I'll get together a web site and you can read what they are saying - but, I'll probably end up charging more too, I don't do web monkey work for free!

Use the handy ebay shipping calculator to figure your shipping. Shipping weight is 1 lb so priority mail is best in the USA and overseas, global priority mail in a flat-rate envelope is great!
I pack very well (see my feedback) so you can be assured of its safe delivery.
