Works great. I was able to relocate my subwoofer wirelessly.
This works great. Our house is full of WifI, cell phones, etc, and there seems to be no interference. I am running a subwoofer remotely so "sound quality" is hard to hear, but it sounds fine to me. (low frequencies are easiest to reproduce, so it is probably fine) One thing, it does introduce a delay. When I ran my receiver speaker setup the apparent "cable length" of the sub woofer was pretty long. Fortunately most good receivers can compensate the timing for things like this. The delay might be more of a problem for high frequency speakers (like front / dialog) if your receiver can not adjust for it.

Great way to move your sub woofer
I didn't know these existed. They are great. You turn them both on, they pair immediately and i was able to move my subwoofer behind my couch. Out of the way, and it's cool feeling the couch shake during a movie. Use a high quality speaker cable that plugs in to LFE.

Worked Perfectly with Subwoofer
Worked perfectly with my Sony subwoofer that used one audio pin cable.

Did not work for me
I've had a surround sound system set up for years and used wireless for my subwoofer and it has worked great. A recent rearranging of things meant that I could no longer practically run a wire for my rear surround speakers. My current wireless setup for my sub was a single channel sub-only system so I needed a new one that could handle my surround speakers as well. This unit looked perfect. Thing that drew me to it were it's claimed 34 available wifi channels, to help avoid interference, and it's 100' line of sight range. My installation would be 25' with line of sight, should work great! Ultimately it was a nightmare. Setup was super easy, the units look great and are a good size. The indicators are clear enough to understand what is going on but I just couldn't get a wifi channel selected that didn't have some interference. The instructions say to press the M button on both devices at the same time (25' apart in my case) to change channels and avoid interference. You then wait 20 seconds or so for the devices to link up again and then I used the speaker setup/tuning white noise on my receiver to listen for the steadiness of the signal. After roping in members of my family to do this on three different occasions, taking roughly a minute per attempt, we could never find a 'channel' that didn't pop/breakup/fadeout/dropout within mere seconds. Additionally, the device gives no indication what 'channel' you are using. So does this procedure of pressing the M button on both devices dynamically select a channel that might work or are you cycling through the supposed 34 channels in order? We pressed the buttons (again simultaneously with two people 25' apart) 40+ times and never found a channel that worked, not even for a minute. I sent an email to OSD via the support address on their website asking how this channel changing really worked and for help avoiding interference. Over a week later no response at all. Hugely disappointing. I don't feel my house is super challenging for wifi interference. We have a single 2.4ghz wifi access point and we are in a detached single family home. We have some wifi overlap from our two closest neighbors but its nothing compared to what you might see in a townhouse, or condo/apartment situation. I'm returning this and simply cannot recommend it at all.

Units work great ! initially frustrated by older instruction manual !
Installed units and so far everything works great. The only issue I had was the manual says units would go into a standby mode when no signal transmitted from amplifier after 17minutes. I called the customer service number and was told these are newer units and do not go into standby modes (indicated by green lights) and lights would remain blue and always active. Meaning you have to manually turn off power when not in use (which I actually preferred). The manuals need to be updated to reflect this fact and to avoid frustration and wondering if the units were faulty.

Almost a great solution
Rearranged my living room and wasn’t able to easily hide the speaker wires for the rear speakers and was excited to find this solution that even included the sub output. Setup was easy enough, but I did have somewhat of a headache getting the levels dialed in. It seems like you need to have the levels up decently high for the rears and sun in the receiver for the rear receiver to pickup. I did manage to get everything to sound as it should except there always was a constant low level hissing noise from the rears, and they would pop occasionally. I might have lived with it if the product was less money, but for $200, not something I’d expect to happen. Will be returning

Got rid of the wires
I was hesitant to buy this honestly, I have had bad experiences with wireless in the past but, with this device, absolutely no issues. Connected the front speaker wires per instructions, rear speakers per instructions, plugged in and instantly connected. I was getting popping noise but moving the mesh network receiver a ft away resolved that. This device allows me to connect my rear surround speakers in my open plan living room without the hassle of running speaker wires. My only objection is the power lights are really brighter, bought some light dimming stickers for a few dollars and that’s resolved. Highly recommend, sound is good.

Worked for about a month. Got it end of April, installed in early May 24, and now its in June 24, and doesnt seems to be transmitting any more. Tested hardwired to my sub from my Yamaha Aventage , and subwooder is working just fine, its the issue with the transmitter. Wrote to their online contact on website, but no reply.

Arrived promptly, easy setup. but it doesn’t work very well. When connected as intended, there’s a significant drop in volume compared to a wired setup. No way to attenuate the volume.
