Hosmart UltraSpeak Pro Intercoms Wireless for Home, Two-Way Real-time Intercom Full Duplex Wireless Intercom System for Home Use, Clear Sound House Intercom System for Business with 1200 Feet Range

Works great, and set up couldn't be easier. I bought this to install a "plug-and-play" intercom system so I didn't have to yell at my kids from across the house anymore. It works exactly as I need it to. I started with just two, and bought two more for additional rooms - they all automatically connect as soon as you plug them in. I have them all linked so when you speak through one, it transmits through all of the others simultaneously, but you can program it to only transmit to a single unit at a time using a simple and easy channel system. (There are nine channel numbers, so my guess is that is the maximum number of units that can be linked together, but I haven't fact-checked that.) The sound quality on the transmission is great - clear and loud (which is great for children and the elderly). It has different settings where you can either transmit by holding a button down (like a walkie-talkie) or press an "on" button once that transmits continuously (like a telephone). What's more, all of this versatility is truly optional and not complicated. Like I said, you can just plug it in and it's ready to go, literally no set up required. They are built simple and compact, the size of a small book, are light-weight and their appearance doesn't stand out any more than any of our other electronic devices. The one possible down-side is that the material feels very light-weight, so it is possible that it might break easier than one would like. However, my kids have already (of course) thrown them around a bit and they held up fine. Also, even if they end up being more fragile than is ideal, they still are worth the very reasonable price.

this is a life saver. we have tried several products, this is easy and effective. good quality and great price.

I pretty much got tired of hearing people yelling from downstairs in my house like Neanderthals so I wanted a cheap and effective tool to talk to people from room to room efficiently. I even thought about getting a professional and permanent system installed, but I decided it wasn't that serious. These were way easy. All I had to do was literally just plug them up and just long press which number I want to assign to each room and its done. Also, long press the talk/call button so it go to auto answer (so the receiving end does not have to touch it to allow you to start talking). Easy peasy lemon squeasy. I have four bedrooms, so I put one in each room, then I put one downstairs next to the kitchen table and one in the upstairs family room and its all good. Now.....if we could just break the habit of yelling around the house then we would be all good. But the intercom system works great.

I really like these devices. They're small and very lightweight (they seem to consist of just a PC board and a speaker). Sound quality is really good. There's no battery option, but that would increase the size and weight. You can pick one of 6 channels if you want to be able to call a specific unit. Example: channel 1 for the kitchen, 2 for bedroom #1, 3 for bedroom #2, 4 for the garage, etc. Alternately, assign the same channel to all units so when you call, they all ring and the other person can answer wherever they are. You can monitor a room without being heard. My favorite feature is the two way communication. You can call another room, and when someone answers, you both can talk at the same time. It basically works as a speakerphone! It's better than VOX because unlike VOX, it does not cut out the first word (it does not have VOX). What I don't like is the sound volume. If someone is hard of hearing, they might have trouble. That's why I removed one star.

We use this extensively for my house; they work extremely well. I wish that you could have the ability to dynamically switch different channels on the fly. You can't, but it's just more of a user thing than anything else. They work, they sound good, and they don't emit weird sounds that you get sometimes with devices like this. Audio is really good. They get loud, and the microphone is actually very good. For something like this, I recommend it.

These things do work. The sound quality is mediocre and I almost have to yell into it to get the microphone to pick up what I’m saying. But it still beats hauling myself upstairs.

Great product. Good sound. Easy to install or move if needed. Will be adding more units to connect more rooms.

These units are not Full Duplex, they are Half Duplex with VOX. Both users cannot talk at the same time, If you attempt to talk while the other party is already talking then you will not be heard. One of the units I was using was in a loud environment and it stayed keyed up all the time. The 2nd unit could never talk to the 1st. I did follow the directions in the instructions and put the 1st unit on channel 1 and the 2nd on channel 2, pressed the #1 button from unit 2, the user on unit 1 pressed the answer button, VOX worked fine, but VOX isn't what it say on the package, it says FULL DUPLEX. So both users cannot talk at the same time. Changed the channel to 3, 4, 5 and 6 on the 2nd unit while unit 1 stayed on channel 1 and the results were the same. We then reversed the order and on unit 1 we changed the channels from 2 to 6 while unit 2 stayed on channel 1 with no difference. If you purchase these units knowing that they are Half Duplex with VOX then they are very good. They work as advertised and sound clear. NOTE: I only had the units about 30 ft from each other for testing purposes, they were transmitting through 3 walls with electric and WIFI all around them. The issue is that it says on the box that they are Full Duplex and they are not. Because one of the locations is in a room with a loud TV and a window unit that is a bit noisy then the compressor is active it stays keyed up all the time and the 2nd unit can never talk to it. So they will not work for my intended purposes. I am returning them.

Excelentes comunicación, hasta compré otros 2 pares

Terrible product. I have scheduled a return but has. It been not been picked up yesterday as scheduled by Amazon

Buen producto, ya había comprado un par y compré 2 pares más

This is an excellent product. It's easy to configure and compact making it a non-intrusive item for the study desk or kitchen bench etc.
