Question: what kind of ear plugs does it use? Where to buy?
Document: Nice unit. Easy to use. Was a gift for my granddaughter. She loved it. A nice buy for the money.
My previous DVD player stopped working after a couple years so I opted to buy this product as it seemed like a good value. I take my DVD player with me to hotels/hospitals and use the AV cord to plug into the TVs (the AV cord was not included in this model). I purchased a cable from Radio Shack for $30. The player didn't recognize that the cable was plugged in. Since I often use the player for this specific purpose, I immediately returned the product.
Don't buy this s*** bad bad very bad button don't work if  just don buy it don't buy it don't buy it cheap s***
It was definitely a good buy for the price. Very true to description and the video quality is exceptional. And the swivel aspect is great too
I'll keep looking but even if there is something, it is NOT what I want to be spending my time doing. I would NOT buy this one again.
We had wished for an easy unit for my 5 yr old to operate. But that is not the case.This is not user friendly and I as well as my wife would suggest to buy another unit of than this Sylvania.
Bought this over a little vacation  to keep my toddler occupied and was pleased. Played all our DVDs, Cd Rs easily. Its vibrant in color and didn't freeze or skip at all. Good  buy and great quality.
The volume is also the same button as the FF. So, if you don't push it exactly right, the DVD skips forward which is also very frustrating to the kids. It also has a bad hum while playing.Do not buy this! I wish I could get my money back.
I am very happy that the new manager has sent a new DVD player to replace the lost DVD player. The original order was probably stolen from my porch. I am happy that I have received this product and it is an excellent buy.Barbara Fragopoulos
I purchased this dvd player for my 2 yr old great nephew who loves Mickey Mouse movies and loves to watch them over and over. He hates for the machine to stop. It also is convenient for my mom who takes the dvd player with her when she takes the baby out and when he gets bored or too busy running around, she plugs up the dvd player and that baby sits for hours watching his movies on this great dvd player.
Answer: Any kind
