Samsung DVD-L70 7-Inch Portable DVD Player
Samsung DVD-L75 Portable DVD Player
Buyer Beware!  This portable DVD player was purchased as a present with the purpose of using it while flying on long trips, unfortunately you cannot hear it even with good headphones over the plane noise.  I took it to Best Buy today to see if there is something wrong with the unit.  The salesman in the tv/dvd department was not surprised by my complaint.  He said the Samsungs have a low audio output compared to other models.  He suggested I ask the Geek Squad in the front of the store to get their opinion.  The person I spoke with was very helpful and said this appears to be a problem with the Samsung portable DVD players from information he had found on the internet.  I ended up buying a booster for $34.00.  When I got home, I called Samsung and that was a waste of time.  Samsung tried to tell me all the manufacturers are having this problem with the portable DVD players and basically they do not care and will do nothing to insure customer satisfaction.  I asked him if Samsung would reimburse me the $34.00 I spent on a booster since their system's sound is inadequate.  I was told not to waste my time.  So much for customer service.  I will never purchase a Samsung product ever again and advise other consumers to do the same.
