Possibly the best wireless mic bang for the buck you can find
This may be one of the best sets of wireless mics you could possibly buy for the money... First, let me point out the downsides: 1. Yes the frequency range of one mic will be out of spec - so you could not use that one, and buy a second set and only use one of the others too, and still have a heck of a deal. 2. I can find no way to have them power on when power is applied - which means you will have to power on your rack and then power on each of these receivers manually (unless I am missing something) 3. They are not rack mountable without placing them on a rack shelf and using double side tape 4. The antennas are not meant to fold flat for easy storage in a gig bag, you would be best to take them off when transporting 5. The antennas are on the back, so if you do put them in a rack, they will be behind a bunch of metal that will reduce their range 6. On a dark stage, you cannot see the polarity, so you might have someone put the batteries in and not have power and have to do it all over again - also, some battery brands are a little too snug, like Kirkland (Costco) so they are hard to pull out once you put them in. Okay okay - so what makes them great then? 1. They are built very well. As others have noted, they are heavy in your hand, they feel about as good as our Sennheisers, like a real piece of pro equipment. While we have not dropped one, I feel like if we did, it would not shatter into pieces like other budget mics. 2. They are good looking and when mixed with our pro-level gear on stage, people cannot tell we didn't spend a grand. 3. The range is more than adequate. We have not found a stage that is larger than the coverage - however, our receivers are in a rack ON THE STAGE, not at the back of a sanctuary or something. 4. The infrared frequency setup is instantaneous and accurate - it's never failed to work correctly, unlike some other brands, even higher end gear. 5. The audio quality exceeds all expectations. I record every show, and that means I have isolated audio from each mic and member and can easily compare a Sennheiser wired to a Sennheiser wireless to an SM57 to the Innopow. And guess what? In almost all cases, the Innopow sounds superb! I'm not yanking your chain here, on quiet to loud songs, they are pretty amazing. And their pattern is pretty good, so they don't pick up too much noise like drums, and they are not bad about feedback. Like most mics, if you move up on it tight, bass response can be amazing. The only weak point is that if you have someone who belts AND cups the mic, it will distort a lot easier than a 57. 6. The price is a big point for us because while we have 3 higher end Sennheisers systems that were bought for key members of our band, other members have come and gone and others have made no investment - these are perfect for them and for guest mics. It's hard to justify buying everyone else's gear, so they get what they get right? At least they get a very decent mic that they are not embarrassed to be behind! There you go, 6 pros and my 6 cons.... The pros far outweigh the cons for sure. And I have a follow-up after purchasing my first system in February, I bought a second system after one of the two mics died.... Not sure what happened, it wasn't dropped, but the batteries would heat up red hot as soon as you would turn it on. Why isn't this a "con"? Because everything has troubles - my expensive bass amp is dead, died at the same show! Rather than cry about it, I ordered another set of mics. I mean, that price, right? But wait - there's more... On a whim, I contacted the seller and told them what happened, early on a sunday morning after our gig... and by Monday morning, they had replied to me and said it was probably a solder ball on the circuit board - and they sent out a replacement.... I had a replacement from them in time for rehearsal on Wednesday.... Used it at Friday and Saturday night's shows and sound as good as ever. Meanwhile, my expensive bass amp is in the shop until the middle of next week before they can even look at it...... So, it's not Shure or AT or Sennheiser, but I would not (and did not) hesitate to buy again or recommend to my friends.

Truly Impressed [professionals review]
To start off, I have a degree in sound engineering and have worked mobile DJing, Radio and Clubs/Festivals for over 15 years. I have used the best systems out there and owned many wired/wireless mic setups myself. My experience with these mics is only over two events and extensive testing at home before I took them on the road. I prefer these mics to my earlier $400 Sennheiser XSW 2-835-A and my current $300 Shire BLX24/PG58 for build, sound quality, features and reception. I would like to check back in a year after many more gigs and rentals before determining their long term reliability, but for the price, as it stands now…. WOW My initial testing was done in a large venue where I had 290 feet line of sight (measured) and was able to walk around brick walls down hallways and outdoors with line of sight interrupted. I wish I had a GoPro running for the tests so I could upload my results but you will have to trust me. I won’t bore you with too many specifics but here are a few that really matter. First off the receptions first weak spot was not until 150ft from the receiver where I was outside the building on the other side of a brick wall and even then there was only slight fuzz to the signal, another 50 ft (200ft and the mic occasionally dropped a beat and became what I consider unusable in a mobile DJ type situation. Line of sight these are even more impressive where I did not notice the slight fuzz (very quiet) until 240-250ft, *the manufactures claimed performance. I was although able to go until the full 290ft of the room with only the very occasional dropout and noticeable fuzz, and this was with my hand covering the entire bottom of the mic (the transmitter) and standing away from the receiver station. Even when the IR on the mic isn’t pointed to the receiver as you are supposed to do while establishing a connection between the transmitter and receiver, I found that at 250ft the mics reconnected immediately with no issues after being turned off and back on again. The multifunction power button on the bottom of the mic makes for a great clickable feel and is a clever place to hide the “Mute” so it does not accidentally get pressed. The screen is backlit (turns off after a short idle) with information for the group, channel, frequency, and battery level. The cardioid pattern is tighter than most and closer to that of a super cardioid microphone. The rear rejection is fantastic. The frequency response is more lively and warm than many $500 mics and will work better or worse depending on the person who uses it. It also feels just as solid as the most expensive microphones in the game. Would I trust it with a 1k person crowd at one of my production companies events? Yes, I already have. Time will tell with the dependability and reliability of this setup, which is most important when you are talking about pro audio applications. This will more than meet your needs if you just want a good karaoke mic or are running small private functions. For big events and gigs I suggest having a second mic setup (as with any brand microphone) as a backup. I hope this helps you while making your next microphone purchase. [UPDATE April 30th 2019] These guys have seen action about 15 times now. This past weekend MC Butterfingers dropped the mic while he was flailing around. The mic has no distinguishable dents or scuffs and still works like a charm. It still hasn't received the reputation of an SM58 but I think that instilled a little more confidence for me on upcoming gigs. In fact, I just purchased a second pair for my rentals rig.

Ease of installation, appearance and price.
Decided to purchased this set of microphones for home karaoke base on the good reviews. Upon testing it out after a quick installation and set up. 1 of the microphones was having static sounds when speaking into, the other microphones was having really weak volume. Did a few trouble shoot to make sure everything was right. Contact the seller and Amazon, they send me a new set right away. The second set of microphones seems to be working correctly without any static and full volumes. I really like the way it look and seem to be well made and not expensive. Only time will tell, will update.

Quality microphone at a great price!
I'm a mobile Dj with a "micro setup" for small to medium events. I was previously using the cheaper wireless mics that use a usb-rechargeable receiver that you plug into your mixer. They had horrible range, felt cheap, and would have signal dropouts. So price-wise, I needed a happy medium between those, and pricey industry standards such a Shures. BOOM, this microphone fit the bill! PROS: - Long range. You'll notice they sell 2 similar models. This is the one with the farther 240 ft + range. And yes, it goes that far, even behind objects and even a wall or two. If you stay in line-of-sight, range is definitely impressive. - Quality metal construction. These mics are very well built. It definitely feels like pro grade equipment. - Great sound. Voices are rich and full, without requiring too much EQ from my mixer (except for occasional FX, of course). - Comes with everything you need including batteries, and even a patch cord. - Your free gift! Order this set, and you'll want to contact the manufacturer about this! CONS: - The mics are a little heavy. But to me, that gives them more of a professional feel. - The power supply is nice and small (not a huge wallwart), but the power wire is a little thin, and I'll have to keep an eye on it during gigs to make sure it doesn't fray. All in all, I would totally buy this mic set again if I had to! I do about 4-5 gigs a month, so we'll see how these hold up. I've taken it to 3 so far, and they've been GREAT! EDIT 3 YEARS LATER - both mics still work like champs! Zero issues! Need a bonus? the free gift from Innopow was a lav mic and they also included a small cable: mini-XLR to 1/4. At first I thought nothing of it. Guess what? You can use this system as a 5Ghz wireless audio transmitter! Your source will have the lav mic unit and mini-XLR>1/4 cable. Your mic receiver box will be with your remote speaker, with a patch cable connecting the 2. Clear wireless audio 100+ ft away! How awesome is that?! EDIT Apr 4, 2023 - while packing up from a gig, I noticed the antenna conductor lead and insulator broke off and fell out from the receiver unit. Super bummed. I didn't claim warranty or repair because it's the factory design inside the board. Don't get me wrong: if you screw in the antennas and leave them alone, I'm sure it'll last forever. It just isn't designed for multiple connection cycles like mobile gigs. I bought TNC bulkhead pigtails and replaced them myself, soldered to the board. If they ever break again, I could do it again easily. This advice is only for users with electronics and soldering experience (see photo).

Great product, incredible price. Everything you want and more.
I don’t normally leave reviews for products, but this product is so good I cannot help but recommend it to others. As a professional DJ, I needed a wireless microphone system immedietly because my other one was being rented out for an event and I learned days before that the venue’s system was unavailable (after I was told that it was going to be for months). This product had good reviews and I figured I would take a chance and try it out. Package arrived quickly in time for the event. All I can say is wow. The system comes with everything you need to hook this up to a mixer. The packaging is very professional and the fact that it includes batteries are a nice touch. The mics feel very solid; the constrcution is excellent and I especially love the power switch (the mics are all metal). The auto-band searching is a nice touch too. Everything from the receiver to the antenna is high quality. I tested out the mic and the sound was excellent-far better than many wired mics I have used. I tested the mics out in the corners of a reception hall and there was no dropping out at all. For wedding receptions and ceremonies, a system like this is perfect. The power switch works pretty quickly and there is a backlit screen on the reicever and the two mics - another nice touch. Don’t spend more money for an inferior product; many systems that cost more than this are not this high quality. Even the entry level Senhiser (retails at $500) does not have all metal mic construction like these. A product like this should cost at least $250-$300. Also, from what I’ve heard, the customer service is excellent, although I have had no problems with this system at all. Highly recommended

Great product. Highly recommended.
Great build quality (just the right weight) and the sound comes in very clear. I am very impressed with these microphones after thinking they would "just suffice". If I had anything to complain about, it would be that there is about a two second lag between pushing the mute button to off and actually hearing my voice. But even then, the vocals are crisp and clear. No feedback and no hissing sound coming from these so far. I have not tried to use both at the same time yet, nor have I tried them at a distance, but so far they are great! I would highly recommend this product to other DJ's and band members.

Exceeds my Expectations
With proper set up and adjustments both microphones work just as good as the high end microphones. I use these mics mainly on home karaoke nights, so vocals should be as naturals as possible. I owned the latest WOW magic microphones and Shure mics. But these won’t hold anything backand performs as good as any of my mics. Continues to have good signal connection even with minor hindrances. My guests like my other microphones but when I introduced these, they now prefer them. It’s true on my experience that just like the other reviewers said that when you max the volume on the receiver, it picks up even the small movement on handling the microphones, so I tend to set the volume of about 7-8 to reduce high pick up. But other than that it is a perfect solution if you’re looking for nice microphones with a tight budget. By the way the mix out is mono and not stereo check the picture I included here. the one on the left is the wire they included in the package... a stereo jack should have two black lines not one on the terminals ends that signifies mono or stereo. update: don’t take 5 minutes to get the best frequency... take 10 or more.

Excellent in Multiple Cordless Mic Environment!
I recently returned a brand name mic because it had problems connecting and had loud distortion from something other than the mic itself. That package came with one mic, and it was more expensive. THIS system had two mics, so I was leery of the price. Plus I had never heard of the company. I read the reviews and decided to take a chance on it, and so far I have been blown away with it. It worked right out of the box and had no problems connecting. We have three other cordless mics all on different frequencies and from different makers. Still this connected by itself, and had no issues with itself or the other mics in the environment. This was a deal breaker as we could not afford to replace all the mics we had previously. The mic handles have a solid good feel to them as they are made with metal instead of plastic. They feel like if you dropped it, (by mistake or on purpose), they wouldn't break up or crack inside or out. They buttons feel like the system should be more expensive also. The receiver also looks and feels well made. They have multiple channels which is really needed today with all the stuff in the atmosphere competing for dominance. The sound of the mics are what you would expect, and maybe a little better for the price. We use a mixer so all of our mics are fined tuned. Still these sound good with no mixing at all. I will update this review after we have used them for a while but everyone is very pleased with them so far. So far there is no downside to this system after using it for three weeks. Will update after longer use. I would say go ahead and buy this if you are wondering. So far so good.
