We received a portable DVD player last weekend from my wife's grandparents. Unfortunately, we purchased our own last summer to take on a long car trip. But, as they live (and purchased this) far away and I've never heard of this brand, we have zero possibility of returning it. It's a keeper.
Problem is the built in power for the headphones is just too low. The unit has a single output but came with a Y adaptor and two pair of headphones. We tried the headphones that came with our other player - same problem. So, either I try to find REALLY efficicient headphones or I get some sort of outboard headphone amp.
My wife and I listened to the player the night we got it, no kids, no road noise, just the movie, and it was JUST loud enough to use. No way in a car. And the little built-in speakers were completely useless. Perhaps it will have to be used only for one person at a time....
Edited to add: duh.. my question... anyone have experience with a small amp? I'm not sure this entire unit is even worth the investment - I know it isn't worth two better quality high-efficiency headphones, unless someone knows of some on the cheap.
