    Default El Cheapo "Bolun" Wireless Mic

    I know, why would I buy this $11 wireless mic.
    Anyone tried one?

    You get what you pay for.

    I wouldn't do it. You will get $11 sound for that.

    It doesn't looks so bad if you look at the specs:
    General Features:
    •30m operating distance (98.425 ft, approximate)
    •FM modulation
    •80-12500 Hz frequency response
    •600 Ohms output impedance
    •Transmitter operates by one 9V battery (included)
    •Receiver operates by one AAA battery (included)
    •Product requires amplifier with a 1/4-inch microphone jack

    The only thing that bugs me is the FM modulation, i'm pretty sure it picks up interferences due to it. Anyway for 11.99$ / free shipping...you don't have much to lose!
    If you shoot something in woods it probably works great.

    Edit : test it and post a short review here! lol

    Yes I usually buy stuff that is cheap like that, just for the sakes of it. Just to see how it is, as mentioned before there is nothing to lose. But I'm kinda broke at the moment , if you get one let us know ok

    I'm wondering in what frequency range they are working, and what your local equivalence to the FCC thinks about them mics.

    It's a Bolun WR-601. Did a quick look and there's a review on YouTube that should answer your question.

    Did anyone notice that even when the guy stops the buzzing, that mic picks up everything? You can hear voices reverberating all over the house. It sounds like the elements used on camcorder mics. In a noisy environment it's going to be as dirty as hell.

    Omnidirectional at its best

    I dare say that the mic on your Sony kit is omni too, CG. But I'll bet it's nice and clean. The good lavs seem to have a short pick up range. Though usually omnidirectional.

    Serious barrel distortion on the door. Well, the distortion is a bit of a turn off on the mic. Saved me $11. Of course, they may have a very powerful doorbell transformer in that stairwell.

    Huey, I prefer omnidirectional lavs - less headache were and how to mount them on your victims, ehm, talents. Me Sony kit has (IMHO) a bit too wide a range for close up interviews, but works great at weddings.

    I actually have the same exact one. If in a studio and maby 24 feet away from the soundboard, really not bad. If outside, my adzens would even be better!

    What does it mean by 30m operating distance??? Would it be how far from your subject you could be???

    The mic is also huge... difficult to hide, if that's what you wanted.

    30m is mostly sufficient if you don't shoot weddings in cathedrals. In the outdoors I get about 200m out of my Sony (without interference).

    ... and with a Zoom or a Tascam + a lav, the sky's the limit! (Not that you will be able to see your talent's lips moving, anyway... )

    I have been using the Bolun transmitter and mike for a few months and am very happy with it. I play the guitar sing at public karaoke type events. I did have to adjust the transmitter, and the volume control is very sensitive. Once set up, however, it works fine.

    Drapeama was concerned about interference due to it’s being FM. Actually, most electrical interference affects signal amplitude, that’s why AM (Amplitude Modulation) is usually susceptible to random spikes such as may be caused by distant lightening and electrical equipment. In FM (Frequency Modulation), sound modulation is accomplished by swinging the frequency around a center point. The amplitude of the signal is clipped to a base level, which doesn’t affect the sound reproduction, but does minimize interference. That’s one of the major advantages of FM. A very weak signal, such as from our space probes are FM and so can be detected and processed to provide useful data. Were they AM, they would be drowned in space noise from stars and more so by human activities on Earth.

    Bottom Line. The Bolun headset mike system works fine for sound systems, but may not be suitable for recording. I say that because I'm not sure a microphone of this design will have a flat frequency response across the human hearing spectrum.

    I ordered two sets on different frequencies. One set works fine and the receiver on the second set doesn't work. Getting it replaced has been nearly impossible.

    That said, the set that does work, works well most of the time. On a few occasions I have run into interference and on one occasion I actually picked up a radio station with the receiver. You want to make sure you pull the batteries out when not in use because it eats batteries, even when turned off.

    I can imagine what fun it is when you shoot a wedding and after the "I will" comes god's voice "and now the weather"....

    Those el cheapos might be nice for home video, but if you do a "real" production, you want to rely on your gear. Even only "few occasions of interferences" won't cut it - you want zero occasions.

    After about 40 to 50 uses the transmitter on the working set I have died on me. I got more than $11 use out of it, but I won't order any more.
