1 starThe battery is supposed to last up to 6 hours, but I’m lucky if it lasts 1.5 hours on a brand new set of Duracell. The product performs well otherwise, but I need it to last at least 3 hours for my use. Also, I’m confused as to why Channel A is showing as out of battery while Channel B still has a full charge.

Good product

I have experimented with various ways of connecting a wireless mike to a karaoke machine with only a wired microphone input. This one is by far the best. Bluetooth transmitters and receivers always introduce a slight delay, which does not happen with this UHF wireless. It is possible to have two Bluetooth transmitters feeding one receiver, but this is much easier to set up. VHF sets also have no delay, but are more susceptible to interference from passing taxis.It uses disposable batteries which last a while, but keep an eye on them.

Pressed into service at our church as an AV technician during the Covid19 pandemic, I looked for a way to get our pastor's iPhone connected to a wireless microphone (or two) so we could do Facebook Live broadcasts. I barely knew what to look for but researched online price/performance options and we found this system worked well for us at a budget price. The recording sounds like you're talking right into the phone rather than from across the room. The settings on the transmitter and receiver took a few minutes to comprehend but now make sense. Once set, you can probably leave them alone. The instructions are slightly on the weak side, not too bad, but again it was not too hard to figure out how to use these devices in practice. We find the sound quality is good, as is the build quality of these devices from Movo. Our pastor wears one lapel mike and a transmitter and we placed the other near a solo musician. We are still working on the musician setup but it's a "sound" improvement over just using the phone alone from 20 feet away.By the way we also tried one of those small "shotgun" microphones you'll see advertised for vloggers and found it did not work well from more than a couple feet from the phone. They are not designed to reach across a room.To make the Movo device (or probably any similar microphone) work with an iPhone XS Max, we also needed two adapter cables: The first is called a "TRS to TRRS adapter cable"...make sure you get one that has the right male/female connectors, probably male-female not male-male. I had to get ours from a big-box electronics store but this one appears to be the same. Without it your iPhone (or any smartphone, I would guess) does not get sound into it from the microphone receiver. Think of it as turning your headphone jack (sound going out) into a microphone jack (sound going in): https://www.amazon.com/Movo-MC3-Microphone-Adapter-Smartphones/dp/B01N9CJDVE/ref=sr_1_1_sspa?dchild=1&keywords=trs+to+trrs+adapter&qid=1587041878&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzVFgxVlpLN1c3QVBGJmVuY3J5cHRlZElkPUEwMzQ0MDAxMVFUQzZWUVFSSFFaSiZlbmNyeXB0ZWRBZElkPUEwODgzOTk2VUdLVkRKM0dFMjJMJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==You will likely also need a Lightning cable adapter if you have a recent iPhone. These are widely available, your phone may have come with this but we couldn't find ours. We got this one: https://www.amazon.com/gp/product/B07MK5F2QT/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1If you have a newer USB-C/connector Android phone, you may need a different adapter to connect properly to the TRS-TRRS cable. If your phone has only a headphone jack, you will probably only need the TRS-TRRS adapter, and nothing else. Best of luck, hope this was helpful.
