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

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.

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 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.

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!

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.

Once I found out the correct connections to use, it was so very simple to install/attach, and to connect via blue tooth, no unsightly wiring on the floors, placed in a corner out of the way, the bottom end that was missing due to no subwoofer is now present, and the system is complete and sounds great, really fine product, especially when there is no sub out connection. My system is from 1988 and it sounds like I purchased it yesterday, wireless addition is great, very happy with this.......thanks!!!

The range of the transmitter is good and the delay is lesser than the traditional 2.4GHz models. However, it has major interference issue with 5GHz wireless AC. It literally killed the wifi reception of my Shield TV Pro, which is on wireless AC. What is interesting is even if I change my wireless AC network to lower channels 36-64, which are in 5.2 to 5.3GHz frequencies, this "5.8GHz" adapter still chokes my wifi reception from over 300Mbps to just a few Kbps. If you don't use any streaming devices that rely on 5GHz wifi, this adapter is quite good. If you use only 2.4GHz wifi, then it is ok. I ended up returning it and got a dual band 5.2/5.8GHz adapter that I can choose to avoid using the same 5GHz frequency bands as my wifi.
