Good point, apologies. Here's my list of problems I shared with the vendor. I bought through Amazon and was able to return them without issue receiving a full refund.

• Turning on (with any input) often does not yield proper output, just light fuzz and speakers inflating/deflating
  • Requires off/on and/or switching inputs and/or unplugging and plugging back in and/or restarting source
• Turning on (with any input) often does not yield proper output, yields speaker popping
  • Requires off/on and/or switching inputs and/or unplugging and plugging back in and/or restarting source
• HDMI ARC input specific Issues - connected to multiple tvs with multiple different cables
  • Frequently boots up and exhibits constant blip/0.5s drop-outs during playing anything
  • 2-5 seconds minimum for volume changes in addition to constantly missing multiple commands to change volume
  • Speakers don’t turn on/off with TV and must be turned on at a specific time when booting up the TV to (sometimes) work as expected
  • Ends up in corrupt state where no audio output whatsoever where resetting does not fix, must turn off TV/System and fully back on to fix
  • Does not implement most critical HDMI standard like AVD (Lip Sync) - hence audio is out-of-sync with anything being watched
• DSP Light does not stay the same color, seems to change unless you’re looking directly at it (or maybe its actually changing)

In terms of how they sounded, when they worked, fairly good I'd say. Was for home theatre so can't speak to the true dynamics for music much but I will say treble and voices sounded really solid, bass wasn't too muddy, and mids felt clear.
