AmphonyMultichannel Wireless Audio Receiver/Amplifier for Making Passive Speakers Wireless - Model 880, Compatible with Model 800 Multi-Channel Transmitter, Better-Than Bluetooth Digital Wireless

I bought a similar set of these (1800) kit in 2019. They worked great out of the box up until about November 2021 when both units stopped working. Given they are independent of each other and they both seemed to do so at the same time my theory is that a power surge was the culprit.So i bought two 880 units and a adopted a much better electrical set up/power surge protector to try and avoid this. For a week both worked great but then one unit started having issues. From describing the issues to the seller they suspect a faulty power source damaged the unit and replaced it. I haven’t installed that one yet but there is a one year warranty and a two month return policy so I’m not worried about actually getting it right.NOW THE IMPORTANT PART… bespoke home theaters/surround sound that use wireless connections (especially for passive speakers that need amplification) aren’t as simple as other wireless things like bluetooth headphones or so. It takes some creativity, patience, luck and troubleshooting to maybe get it right/operational when you are dealing with other interference from about everything that is wireless these days and that’s even before you get into the unique electricity needs for something that is both wireless and has a built in amplifier independent of the speaker. If that’s too much for most, get a blue tooth sound bar with a matching sub woofer and get on with it. But if it’s not and you want a more classic 5.1, 5.2, 7.1 or 7.2 system with wireless surround speakers And/or sub (s) this seller (who is about the only person except a best buy house brand that even tries to make these) does a great job re customer service imo and that’s worth the price of these in itself.But remember creativity, patience, luck and troubleshooting if it doesn’t all perfectly come together 5 min after you open the boxes!

I purchased the transmitter along with an 800 Receiver and two 880 receivers so I could avoid running speaker wire across two doorways. The concept sounds amazing, but the reality is that the equipment doesn't work as described when you live in an area where there are other wireless networks. When I hooked the equipment up, the speakers had a high-pitched buzz and the music kept dropping out. I consulted the troubleshooting guide and slowly worked my way through all of the recommended fixes. I relocated the equipment, I added surge protectors, I moved my wireless network to a different band (which slowed down my network and caused problems with the rest of my wireless equipment that took some time to resolve). I upgraded all of the speaker wire and re configured my stereo setup. But none of these fixed the problem, so I called Amphony technical support. When I described the situation and all of the actions I had already taken, the tech support guy said it sounds like the equipment is working as expected and that because I live in a high-rise in the middle of a densely populated city, there is just too much interference for this equipment to work. Unfortunately, by the time I got through all of the troubleshooting and equipment configuration, I was already past the 30 day return window. Amphony told me that no customer would want to purchase equipment that had already been in use by another customer for over 30 days. I honestly had to laugh at that. The equipment is cheap plastic like something you would buy at Radio Shack for $15 and the speajker wire they send is low quality. I'm out $300 and doubt I'll be able to sell this equipment on eBay. I'm sure Amphony was just glad to make the sale and it doesn't surprise me they don't want their equipment back. If you live in a remote area, this might work for you.

This replaced my speakers wires for my surrounds and surround rears when i moved... and they do a great job... compared to the first set.. (the little dual kit).. these are a better option... and compared to older kits.. this one comes with a better manual... your 5ghz wifi channel may need adjustment... the harder you push the little amp in them.. the hotter they get.. and they will burn out on you.... don't use them on the older 6ohm woofer/tweeter box speakers... they will last for about 3 years... but the set on my rears have been going strong..
