The sound quality was great, 2 wireless microphones were nice for duos (though the effects didn't seem too noticeable), and hooking it up was easy (YouTube provided all the karaoke content). Lastly I don't Karaoke very often, but still found a use for it as a pretty decent sound bar for my office TV given it's form factor and look (downside being it doesn't default to the optical input for this use and ostensibly has to be set to it every time but it's marketed as a Karaoke machine so I can't really complain about that). *My unit was missing the remote control it should have came with but emailing the support address got me a remote pretty painlessly. Review: Small yet powerful - The RHM K222 karaoke machine offers an impressive blend of convenience and sound quality, making it ideal for household parties or casual entertainment.
