I’m a sports announcer (roller derby). I wanted a mostly portable, wireless mic set that I could carry with me to any venue and be able to plug into any sound system or mixer. There are a LOT of options from one-mic systems with a little plug-in receiver to this. I opted for this and MAN has this set been great! I’ve used mine probably half a dozen times and it’s been great so far. The range hasn’t let me down - from an average skating rink to a larger college campus basketball arena. The 1/4” audio cable makes it basically universal. I like the ability to change radio frequency if there is interference. Battery life has been impressive too - I’ve probably done half a dozen two-hour games and both mics show full battery power (I do remove the batteries before storing them). The only thing I wish I could do is get a seperate body pack mic that I can learn into this. The kits are either two mics or two body packs and as a coach, it would be able to talk without having to hold a mic. The Innopow body packs that are for other systems don’t seem to use a frequency that this can hear. Maybe in the future a seperate body pack will be available. Until then, I, my other announcer and our fans are super happy with this. If it lasts me, I’ll stay loyal to this brand.Update about 5 months in: After a few months of regular use, the original batteries FINALLY wore out. I can’t ask for better battery life. This set is still performing. The mics have been dropped but they feel pretty solid and haven’t been harmed. The other night, the whole receiver fell off a mezzanine railing about 12 feet to a concrete floor and wasn’t harmed. I recently had a situation in one venue where one of the mics worked great, and the other didn’t work at all from where I was. Once I scanned that mic into a new frequency channel, it worked perfectly. This has also outperformed more expensive, name brand wireless mic sets that places have had. So, if you’re finding that a mic isn’t working or doesn’t have great sound, try putting it on another frequency channel. It’s a little tricky to do it if you don’t change channels often but it’s been successful.Update after two years: Still working great. Battery life is still impressive. I purchased two separate body packs and headsets. I keep the whole set: receiver, mics, body packs, headsets and cables in a suitcase sized padded case with a customizable foam insert. They’ve been used every few weekends for two years and they still perform well after wear and tear of being at many games and tournaments. This mic set has done the announcing at a number of large tournaments. Still, the biggest key is each time it’s taken somewhere, scanning for an open channel and learning the mics in. It takes seconds.After two year update: man, these keep performing. Both mics have been dropped and had hard blows. I thought one was broken but once I played with the power button, it’s fine. I messed up one of the headset cables and the power cord by closing my Pelican-style case on it but that’s my fault. These get used every few weeks and they never fail. It does seem like the headset mics have a higher gain than the handhelds but that’s no issue at all. These have been used at small events and national tournaments. For the price, I couldn’t ask for a better product. Again, having a clear frequency is important. Learn how to do the auto scan so the receiver can find a clear channel, and then learn the mic or body pack in. I do this each time I use them. One of the first times I used these at a rink, one mic worked well and the other didn’t work past 10-15 feet and changing channels absolutely fixed it.

UPDATE: I'm lowering the rating from 5 to 4 stars because in the last few years our church has had 5 of these microphones (two of these sets and one replacement mic) and 2 have stopped working.I'm the sound guy for a church in Chicago. We purchased one of these sets, and liked it so much we purchased a second set when we started holding additional services on the south side. We eventually had one mic start to cut out (which was understandable since our rowdy pastor was rough on it), so we bought a single replacement mic. When we recently started in-person services back up after the pandemic, we found that another mic was no longer sending a signal no matter what frequency or side of the receiver it was set to.It's still a good product for the price though. In fact I'm going to buy another single replacement mic right now.ORIGINAL REVIEW:Great sound and reliability. Better for talking than singing, but I've never been satisfied with the wireless mics I've tried for singing (even the gold-standard Shure brand ones).The only problem was heavy whooshing and thud sounds depending on how close a speaker held the mic and how they pronounced their 'p' and other windy consonants. The mics have a foam screen under the metal cage, but it apparently isn't enough. We slipped a less than $2 wind filter over each mic and they are perfect now.Even the little details are great, like they don't make any popping noise as you turn a mic on and off, and they don't even go through batteries quickly.
