Summary: I purchased these for an office environment. It's possible the many wireless networks were creating some kind of interference? I'm not sure. But in any case, the headphones rarely traveled more than 2-3' away from the transmitter. There was always a mild to moderating buzzing or hissing (or whining?) in the headphones. The transmitter is smart enough to "open the channel" to the headphones only when there's sound to play.
Summary: Obviously the person who designed this never actually used the headphones. The problem is it's almost impossible to find the volume switches with your fingers when you are wearing the headphones.The switches are cheap popple switches under plastic buttons that are almost flush with the headphone shell. The button plastic is the same as the shell so there is no tactile way to find the button.
Pros: I upgraded from a Sennheiser HDR 130, an open back design. A definite improvement in background noise, Max volume is less than the HDR 130 but adequate, would be convenient to have more gain range to make up for low level material.
Summary: The Digital in the product description refers to the transmission only. A true Digital headphone should have Digital input. At this price point, one would expect to see they use either Optical or Coaxial digital input. I also own the Panasonic wireless Dolby Surround headphones which sounds much better. The only problem with it is that I must sit in front of the transmitter (within 45 degree) or the infrared signals will be lost.
Summary: Sadly this product has been a big let down. I read all the reviews and decided it was going to be worth paying a fair amount of money for a good product but............ The first pair had to go back because the batteries would constantly disscharge, I'd say this was just an unlucky fault with this particular pair however........
Great Sound & Great Looks - Just a shame they are completely unusable!

Summary: Here is a question I was asked many years ago in a GCSE level Design and Technology exam paper: Q 13. Which of the following components would be most suitable for a warning indicator on a control panel? A. A 6mm Red LED B. A 12mm Red LED C. A 4mm Flashing Red LED D. A 12mm Blue LED The answer is C. Here is a question of my own making: Q 1. Where did Sennheisers designers go to school? The answer, apparently, is: nowhere. These headphones sound excellent.
Excerpt: Great sound and fit. But beware as the sound is transmitted over the 2.4gHz frequency the same as most Wi-Fi signals. It caused my Wi-Fi to be non-existent which was disappointing as I bought these for online gaming and watching Blu-Rays. The sales rep told they would fine when I purchased them. When I tried taking them back the Store Manager refused to refund my money. So buy at your own risk.
Summary: these are the first expensive earphone ive ever bought so i can not compare to other high end models i can only give my personal expierence, positives first they are very comfortable they sound amazing music and movies you will find yourself breaking out old music just to hear it on them you can wander around your house with perfect reception if you are that way inclined negatives (all minor) the buttons on the side, on off button in middle of volume buttons you will...
Summary: I was disappointed with the wireless headphones for various reasons and unfortunately will have to exchange them a) sound not as good as I would have expected ... in fact quite a bit less than expected b) latency delay is quite intrusive eg producing a noticeable ghost sound in the headphones from the TV when it is being listened to through the speakers by a person even with good hearing d) probably in an effort to avoid the ghost sounds the headset clamps on a bit too...
