Hollyland Mars T1000 [Official] Full Duplex Wireless intercom System for 5 Users-1 Base Station & 4 Wireless beltpacks with Dynamic Ear Headset & Microphone for Church, Drone, Events, Broadcast.

I have been streaming a classical/pops concert over the summer, which takes place in the end zone of a football field. Obviously, intercom to the seven cameras is essential. I have a wired low-price off-brand intercom system, but the idea of pulling about a thousand feet of wire did not appeal. I first tried out an Eartec system, but despite being well within the advertised distance constraints, the signal was just not strong enough to cover the field (I was directing from a camper off to the side of the end zone.) So I went looking for a replacement system. ClearCom wanted about $10k for a five-headset system, money I couldn't spend and still two headsets short. So I discovered Hollyland online. I watched several video reviews, all of which were very complimentary. I bit the bullet and bought two Mars T1000 systems, with the intent of wiring the two base stations together with a long Ethernet cable.Observations:The beltpacks are very sturdy and well-made, although I would like something other than a non-locking TRRS connection for the headsets themselves. The headsets were reasonably comfortable, maybe a tad on the small size for some heads. In operation, if no one is talking (or has their mic open) the system is as quiet as a graveyard - which when you are used to a little hiss or sidetone can be very disconcerting.But did they work?After a fashion, I guess the answer is "yes." The range wasn't really great, even with Base Station 2 wired 200 feet from Base Station 1. With people arrayed in a semi-circle about 100' from the base, there was always some time when one cam-op or another wasn't hearing me. During the performance, I think the fact that there were 2000 audience members there soaking up the RF was a problem, even though I raised Base Station 2 10 feet in the air on a pigeon plate and tall light stand. Also, if more than one person in the field tried to talk to the truck at the same time, basically it all jammed up.So, will I keep it? Yeah, I think I have to - there's not much out there that can support up to 10 headsets at once for less than $20k. But it's not perfect.

Like others have said, it is ALMOST there.Pros:Easy to use.Can use any TRRS* (see cons)Okay range, great for small spaces/ballrooms.Value/Price.If you didn't need to have someone speak and wanted to just run com to them, this is a great easy way to do so. (ie cameras).Cons:The Mute/Un-mute is not great if you need to be able to chat quickly. To Unmute you have to hold down the mute button and wait 3-5 seconds before you can chat.Noisy if you use the provided headsets to mute (push mic up overhead).Own TRRS headset does not mute the mic if you push mic up overhead.Bought the Two/Four Wire com addition but never was able to get it to null, though it worked.Never really had a great sidetone so was unsure if I was muted or not.
