Good quality, good price, make sure nobody messes with the frequencies

Bought this unit to replace the lesser expensive version, that worked okay, but got some interference from (?), and to improve the sound quality. Very pleased with this unit!

Excellent, clear quality. Depending on the location you are using it, there are multiple settings to avoid picking up any sort of tapping or clicking background noise. Do find a good place to put it however, as it is way heavier than it looks!

We purchased this to replace an older 900 MHz transmitter / receiver that had poor picture quality and suffered interference with microwave oven.  This unit's picture and sound quality is quite good, and is free from interference.  Our application range is about 25 feet, separated by a stone wall, but I suspect signal path is through a doorway between the units.  We do have occasional signal interference when we walk directly in front of the receiving unit, although this is not significant problem.

It works well.  I haven't experienced any static or other stations cutting in.

I used this item in my home studio and it works well. It does a great job at controlling frequencies in the mid low to mid high range. The item was well packaged and delivered in a timelier manner then others. All in all make sure you do a math check on your room to see if you even need this item because it could be over kill in most cases. Four use it worked well and as advertised. Let me know if you need more info.

I'm getting mine in few days and I know right where to put it.  I figure with the antennae cable shielded with magnets and ground.  May very well eliminate the hum with magnet tape.  Outdoor antenna will help.

Hard to find a simple but high quality radio these days.  This unit is very sensitive even without an add on antenna.  It is also highly selective and does not drift when tuning in weak stations.  I use it next so computer gear and don't notice any spurious EMF noise.  Sound is about as close to audiophile quality as you can get in a single speaker radio

I purchased this noise isolator for two applications in my home, both of which were resulting in terrible ground loop humming that this fixed:

1. I have ethernet cables run throughout my house, so I purchased an ethernet-to-stereo adapter so I could send audio to any room in my house through the ethernet ports.  Now I can play music in my office and family room at the same time, without an annoying delay if I tried to stream it digitally.

2. I have a bluetooth receiver that hums loudly when the BT signal is lost or disconnected.

Basically any time you have two devices with different power supplies, or especially plugged into two different outlets you can get bad ground loop noise.  If this suddenly stops working I'll update my review later.

Mostly liked this radio, but the deal-breaker was the extra static and interference on weak AM stations when using the supplied AC adapter.  No such issue when using batteries.  A separate single sheet explains that AC switching power supplies can cause AM noise and recommends the radio be at least 1 foot from the power supply, which I did, but I couldn't detect any difference in the extra static using the AC adapter as a function of distance from the radio.  For strong local AM & FM stations, the sound was crystal clear using battery or AC adapter.

The cable works pretty well.  The picture is for the most part noise free.  And having 25 feet of cable means getting to be anywhere in the room I want while working off of the big screen.  The only problem is that from time to time a burst of interference pops up and that can be a bit annoying when you are watching a movie or trying to read something.  I'm not sure what is causing it, but I'm betting the cords not as well shielded from outside fields as it says it is.

We use them for desktops in my office. Minimum cost to get decent sound without cell phone feedback noises. also they  are shielded so they don't affect monitors.

Note: I am using this for audio only; I have no idea how well the video function works.

My initial plan upon purchasing my new home was to wire it for multiroom audio.  These work well enough that I probably won't do that any time soon.

I bought these for a party.  I wanted to have at least three zones, the living room, basement, and garage.  Range is decent but keep in mind that each wall will attenuate the signal appreciably.  I have no idea if you could really get hundreds of meters out of these; maybe in an open field but the range in a home will be much less.  When I had the receiver on the close side of the garage, it worked fine, on the far side (3 car, further but no additional walls) it didn't really work at all.

Some things to keep in mind:
These do not have "diversity reception" or anything like that (even cheap wireless mics usually will).  This means that you CANNOT have them at any old angle or position and expect them to work perfectly.  Wireless mics are designed to be tolerant of position and angle, these are not in the slightest.  That's no problem though, just set them up and tweak the position and antenna, and don't move it.
Human bodies will disrupt the signal -- place them so that people aren't likely to walk across the signal path and you'll be fine.
Work best with a strong input signal -- Cellphone headphone jacks are notorious for having weakish output into line in.  If you use one for this, you will need to turn it up more on the receiving end, which means you are turning up the hiss as well.  Use a laptop or place a mixer or preamp after your cellphone to boost the signal.  There is hiss from this system but its not a significant issue if the input signal is strong.

Clear reception, works as advertised, worth the price.

Great quality, very flexible. The connectors on the end are VERY low profile as well, so you can keep everything neat and tucked away behind your head unit.

Good shielding, doesn't have any signal noise even going alongside my 4AWG power cables.

I'm surrounded by stations on all sides. I noticed this would cancel out some stations that normally came in fairly good with just the radio's built-in antenna, if they were located on this antenna's dead sides. Gain some, lose some. At least now I'm getting my two favorite stations, in stereo, without the multiplex hiss.

I think we should of paid more for the 120 HZ vs the 60 HZ.  Only draw back is a little fuzz on some stations !!!

I doubt there are many places where this can be used successfully with a nice stable signal. I live in Ft Myers....we have  a dozen FM stations and we do not live near any major metropolitan area.....I could not find a clear frequency. Another item for My favorite Hospice charity store.
