Summary: I've tried the Sony's, the RocketFish (stay away from those. Simply TERRIBLE), and these are awesome! I've ready many reviews that said that the bass was not that deep.
Pros: Sound Quality, Big Bass, No drop out, long battery
Cons: Too big to lay on your side with them in bed.
Summary: These headphones really are superb in all respects. I've owned many pairs of headphones, including several pairs of Sennheizers, over the years and these are the best...
Pros: The sound is incredible; it just doesn't get ANY better than this...really. These rock!
Summary: I have used Sony wireless headphones in the past and settled for the hissing and interference because I thought that was as good as wireless got.
Pros: excellent sound, comfort, charging cradle, options, long operating time per charge, easy setup
Cons: no printed manual-only CD, quick-start guide is pictorial guide only
Summary: I live in an apartment complex, so I cant really crank up the volume watching action movies or playing video games, but with these guys I can, and I honestly don't feel
Pros: Great sound quality and amazing surround sound emulation
Cons: Price, Not as comfortable after 3+ hours of use
Summary: I use these for night time TV viewing so as not to wake my wife. After using the RF Sennheiser for a number of years, I was ready for a digital pair. These are superb!
Pros: Very clean signal, excellent sound quality and some nice features.
Cons: Pricey but hopefully they'll last longer than the RF ones.
Summary: I use hearing aids and when I watch the tv after the wife goes to bed, she can hear it very easily since I always have the volume up pretty high.
Summary: I have only operated this device for about a week. Transmitter and earphone receiver is very good. I can hear headphones in every room in my 4500 sq. ft.
Pros: Great operating instructions and well built transmitter.
