Q: Can these headphones also be used to listen to surround sound ?

A: Yes. In order to experience surround sound via headphones, it is necessary to convert the

surround signal into something called a ‚binaural signal'. There are many binaural processors on the

market which can be connected directly to the transmitter. It is recommended though to test the

binaural processor prior to purchase since the surround perception very much depends on your

hearing and a particular binaural processor may not be suitable for you. You can test the processor

using corded headphones. It is preferable to use processors that provide a digital audio output

which can directly connect to one of the digital transmitter audio interfaces.

Q: What are the benefits of transmitting the full data rate without using audio compression ?

A: Since our transmitter transmits a data rate of over 3 Mbps (3 million bits per second), the audio

can be transmitted without audio compression. Also, forward error correction can be used. The

reason that other systems use audio compression is to reduce the extremely high data rate of a

pure (uncompressed) audio signal in order to either be able to store that signal or transmit that

signal more easily.

The biggest drawback of using audio compression is that the quality of the audio signal is reduced,

such as in MP3-compressed audio. This is because audio compression removes parts of the music.

Some types of music which are particularly difficult to compress without noticing audio degradation.

Systems using audio compression are not able to deliver CD-quality audio.

Forward error correction adds additional data to the transmitted signal so that in cases where the

data may be corrupted during transmission, the original data can be recovered at the receiver. This

ensures a very robust transmission.

Q: Do I need line of sight between the transmitter and headphones ?

A: Line of sight between the transmitter and headphones is not necessary for the headphones to

operate. However, for maximum range and reliability, we recommend that the transmitter be placed

such that the number of walls of obstacles between the transmitter and listening area is reduced to

a minimum.

Q: Do these headphones work with rechargeable batteries ?

A: Yes, four rechargeable batteries are supplied. These batteries can be recharged inside the

transmitter charge bays.

Q: How can I mute my television while the headphones are in use ?

A: Many TVs will mute their speakers if an audio cable is plugged into the headphone output.

However, most TVs can also be muted by pushing the "Mute" button at the remote control.
