First, I should mention if you do live concerts, loud events, etc these are not the headsets for you. You need heavy duty headsets that cover both ears.

We bought this system to use on multi-cam seminars, live-streaming events and classroom training videos. For this purpose they work just fine. We ran the system on a single charge for nearly an entire 8-hour day. This includes the master headset which was open the entire time. I was impressed by the battery life, which I was not expecting.

Now, we have not tested these at a great distance, but they worked fine with about 200' of separation. We had our control room set up in another room from where our cameras were placed and this did not cause any problems.

If you need a more robust system, you're going to spend thousands of dollars, but if you need a low-cost option, these headsets work fine.

This product is allright for simple productions and lectures. Aslong as the sound system is not loud or playing music. We tried to use ours at a multicamera concert. Bad Idea, no one kenw what was going on. You would probably have a hard time even in a normal worship eviroment. they are basical super walkie talkies, dissguissed as professional intercoms. I bet they would do fine in a wedding though.

I purchased this set looking for a way to coordinate mythree cameramen during live event recording. We needed tocommunicate from distances of 10'-200'. These work but withlimitations. First and foremost only the master headset cantalk and listen all the time. The Three remote units mustpush a button to speak and release the button when theconversation is finished otherwise the channel jams and noone can speak. It's not an open mic system so be warned. Secondly range is about 150' max. On occasions where oneperson is inside and another is outside it's a toss-up as towhether or not the signal will go through well enough tohear. The master can tell a signal is trying to transmitbecause of a click and noise on the line. Most of ourevents are in churches, gyms, or ballrooms so they get bywith the bare minimum. The sound quality is less thanspectacular. You can hear the person, but do not expectgood sound quality. It's sounds like a muffled telephoneconversation. It gets the point across, but sometimespainfully. I was going to return the set, but there reallyisn't an alternative for less than thousands of dollars. I'm glad we kept them because now I know exactly when acameraman is changing shots and can tell the others to hold. It has added value to my business.

Problems Encountered: They look like they were designed by Fisher Price. They arebig plastic walkie talkies. The frequency system is DIPswitches so be prepared. Battery life is 3 hours max. Eartec sells a 9-volt adapter. I wont list the price butjoking comes to mind. It's 3 wires with $.50 connectors oneach end.
