OSD Nero 5.8GHz Wireless Surround Sound Rear Speaker Amplifier 2 x 50W with Subwoofer Output

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.

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.

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.

Bought this to relieve the agony of wired speakers in my room. This is a game changer. I only wished it supported more speakers. Now I have a stereo room where I can listen to my Jazz and some old school and just relax now that the kids have left the home. Good product.

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.

Really glad I took a chance on these. This updated model works perfectly. It only took me about two minutes to set up. The range is great and I have it behind a wall 20 feet away from the transmitter. Other reviewers talked about having to change channels, but this model, the one pictured in the description, doesn’t have a button to change channels…it doesn’t need it. Hook it up to your sub, powered speaker (with sub out) or amplifier/receiver and they work like a charm. Highly recommend!

Allowed me to move my subwoofer to a back corner of the listening room wirelessly. Attempts to wire in and use of a 2.4 GHz transmitter both produced unacceptable noise. This device produces no unwanted noise and any signal delay is not audible to me.Initial pairing of TX and RX units didn't work as described in the instructions. What did work for me was to set the units side by side, power up both units, then press the "pair" button on the RX unit. So if you find that the instructions provided don't work for you, try my method instead.

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
