5.1 Sound in Your Headphones if you find the Right Accessory
This device produces dolby analog sound when connecting it to your portable device but does not produce digital 5.1 sound unless you connect it to a dvd player with dolby/dts inputs using fiber optic cable with a 3.5mm jack adapter which I finally found packaged with a fiber optic cable at Wal-Mart. Since then I have been enjoying watching my DVDs in 5.1 sound all channels going through in my headphones to produce less noise at work and when I have a condo/apartment.
Great item but do recommend rechargeable batteries if you watch more than 2 films a day which I do!
