FIFINE 20-Channel UHF Wireless Lavalier Lapel Microphone System with Bodypack Transmitter, Mini XLR Female Lapel Mic and Portable Receiver, Quarter Inch Output Perfect for Live Performance-K037

I used 4 of these wireless microphones as part of a recent amateur dramatics stage production. We had 16 wireless mics in total, of various types, all working well together without interference.The good:* They just work* Each receiver and transmitter are coded, so only connect to each other, even if you change the frequency of the transmitter* Batteries in the transmitters last a decent time, at least 6 hours, and have a battery indicator* The lavalier microphone sounds ok, but the sound is a lot better if you replace it* Range was never a problem for us* For the price they are amazingThe bad:* The receivers don't have a battery indicator and use up their AAA batteries quite quickly. We learnt to start each performance with a fully charged pair of AAA batteries* The lapel mics sound ok, but not great - I would have used them, but was happy I replaced them for something better* The lapel mics need to be accurately positioned to pick up the speaker - that is high and pointing directly at the speakers mouth. We had problems where the cast clipped them to their lapels which left them pointing to their shoulders and picking up almost nothing. They need to be top of the shirt pointing straight up* The power and frequency change buttons look identical. It is very easy to change the frequency when you mean to turn the transmitter off.* One member of our cast managed to keep turning off the mic by accident during costume changes. I would have liked to have had the Sennheiser design where the buttons are under the battery flap, so they can't be operated by accident.* The mini XLR connector for the microphone makes it hard to replace - almost everything else uses a 3.5 mm jack* The aerial came off one of our receivers. It didn't matter to our performance as our mixer was beside the stage and still picked up the performer.I replaced all the microphones that plug into the transmitters with the Discreet Neckband Headset Microphones by Chord. They come in a box labelled FNM-35. They don't have the same connector, so I cut off the existing connectors and soldered on replacement mini XLR connectors. After we had done that these sounded awesome. I couldn't tell who was wearing these and who was wearing the really expensive wireless mics we hired.

This is a pretty decent mic, considering the cost it is in fact rather good, best position seems to be on a shirt pocket, or roughly thereabouts, any closer to your mouth and things start getting distorted.Easy to set up, handy having 20 channels as you can switch channel if you are getting any interference, sound quality is good but not great, there is an audible background hiss which I can't seem to get rid of but again this is not a top quality mic, it is what it is.Having said that, if you are giving a presentation or demonstration to a group it is ideal, if you are doing a presentation on video you will need to do some post processing on the sound.All in all I am still very pleased with it and it will get a lot of use, I can't comment on battery life yet as I haven't been using it for long.Would I buy it again? Yes, despite the 4 stars I would as it is very useful and very good value.Recommended.

I create educational screencasts and found that my expensive condenser mic was overly sensitive to echo and background noise in the room. I therefore started looking around for a wireless Lavalier lapel microphone. I was nervous about buying a big name brand in the first instance since systems like Sennheiser can start at £500. I therefore I thought I'd first experiment with this Fifine.I confess that I was nervous about making this purchase this after reading some of the reviews here about the Fifine lacking sensitivity; however, since I was in any case looking for something less sensitive than my condenser, I decided to give this one a go.My conclusion is that this Fifine delivers much better sound for my purposes than the condenser. I don't know why people are saying its output is too low; I can only think they're going through a weak amp or pre-amp as I'm finding it delivers more than adequate output levels.If I were to find a negative, I'd say that the casing is plastic-y compared to the solid strong casing of, say, a Sennheiser; but then hey, you're spending £40 on the Fifine rather than £900 as you would for a Sennheiser, and from a sound perspective, I think you'd struggle to hear a difference between them (at least for non-professional recording applications).How long will this Fifine last? Who knows. But based on my initial test, this product has completely exceeded my expectations - especially after reading some of the less positive reviews here.

You need a good quality speaker......am using a Logitec PC speaker with woofer which gives an excellent, controllable, sound volume and quality but wearing the mic on my lapel or any where below the mouth level wasn't good enough, couldn't hear my voice, but wearing it clipped to the arm of my specs absolutely done the trick. I guess you get what you pay for!

After initially being impressed with this setup (and writing a favourable review), it has since failed - costing me a lot of time in wasted recording; meaning that I'm editing the review accordingly.The unit started randomly cutting out mid-recording - you'd get decent audio and then - bang - nothing. It did this twice and I thought it was probably just weak batteries causing radio signal loss, so I changed them. Alas, this was not the case and now all I get from the unit is very loud white noise. It appears to be a fault with the Mic itself - rather than the transmitter or receiver - as the output signal goes completely dead without the mic plugged it (but with the mic plugged back in is smashing out the random noise).Very disappointed and seem to have no way of getting a replacement or refund.Don't waste your money!!!
