A:AnswerThe same model mumber with an "A" after it does not have 12 volt input and Best Buy cannot tell the difference and they only have the "A" model in spite of what they may show on the demo shelf. (Which they showed me) Their computers cannot distinguish and the only models they have are the 115 volt "A" models.
A:AnswerEarbuds and earphones are just a type of speaker. Any type of audio output device can be connected to the TV, such as speakers, earbuds or stereos, if you use the 3.5mm or digital coaxial connection.
