A:AnswerIt doesn’t have any songs pre programmed. You can connect to a Bluetooth device and run music that way. I connect through my phone and play the kids songs that way.
A:Answeryou must plug a USB storage device in the back for additional storage. Moreover you should check the encoding rate of the file, a 320kb/s mp3, is going to take 2.5 times the size of a 128kb mp3.
A:Answerthe item is fairly durable, but the microphone wires can be ripped out, however you could very well get an extension 3.5 millimeter cable, which would also assist with reducing the feedback echo between the speakers and microphone.
A:Answerthe echo is feedback due to the distance between the microphone and the speaker, there is no noise cancellation software, as i believe this is powered by a microcontroller.
A:Answeryes, but that is the case for all bluetooth audio systems, while they create a buffer to deal with any loss of connectivity or connection speed.
A:AnswerI would say that the cords are about 3 ft long or a little longer, but not much more. To sing right, you need to bring it close to you.
The kids love to bring it real close, but when I sing with her i do it at a normal distance.
A:AnswerYes there is a volume control for both the microphones and the music. This device does not have a CD player and works by transferring music over via a USB cord from the computer or acts as a blue tooth device with songs from your phone.
