Our Overall Impression of the Akai KS878-BT

Just by looking at the Akai KS878-BT, it look’s like you and your family will have great fun with this home karaoke machine.  The design with the lights, speakers, and pedestal make it look like a device you would use at a karaoke bar.  This karaoke machine is not all looks though.  For the price range it’s one of the better sounding karaoke machines on the market.  Keep in mind we are referring to the sound when playing music through the speakers and not the sound of your voice through the speakers.

Don’t get us wrong the sound combination of music and singing isn’t bad on this device but we feel it could be much better.  The quality sound of one’s voice through the speakers could be due to the quality of the two microphones included with this karaoke machine.  To get better sound it might be better to purchase separate microphones to use.

So in our opinion the Akai KS878-BT Pedestal Karaoke System is a quality system.  With a microphone upgrade it could be the best sounding system in it’s price range currently on the market.  Only thing is once you factor in the cost of the microphone upgrade you are now in the upper tier price range on home karaoke systems. Even without the microphone upgrade this device will provide the family with great entertainment and fun.  We feel for the price this karaoke machine without upgrades is a pretty good value.  What you must determine though is if you do want to upgrade the microphones is the value enough that you can justify not just going with a higher end system.
