Nodelay Upgraded,Lossless Sound Quality, S-AIR100-PLUS Wireless Surround Sound Rear Speakers Kit,Built-in 2 x 75W Amplifiers,5.8GHz Automatic Interference Avoidance,14.8ms Ultra-Low Latency

Probably the worst purchased I have ever made, I was looking for the wireless speaker kit to hookup my Denon AVR with 5.1 surround sound speaker setup. The components, built quality, and the materials used of this wireless kit are so cheap (the chassis, connector, weight…etc).The spec is totally different from the advertised on the Amazon listing.First, it not 5.2G/5.8G dual-band wireless technology, it only support 5.8G (the manual shown the Wireless Frequency Range: 5.725 - 5. 825GHz.Second, the sound output DOES NOT reach to 2 x 75W (4Ω) from the listening experience, sounds like 2 x 30W that only produced tiny of sound level and will get distortion and hum noise if you tried to set the output more than 60%…The sound quality is not great as well, noise, popping sound, clicking and hissing issue.If you are looking for the surround sound speaker solution, stay away from this!!!!

You can't control the volume of the surround sound speakers.

States 75 watts at 4 ohms. I have high end 4 ohm speakers and the volume level is les than my Rockfish unit starts clipping at less than 50% input signal .Stay away from this junk.

Failed in 90 days.

Would not stay connected. 3x was sent used replacement

These speakers are really disappointing. The specs listed on Amazon don't match the actual ones so the performance on these are really bad for what they should be and the price point.
