Digital wireless headphones with surround sound
Recording and Studio
The Hearo 888 Titan and Hearo 999 Audiosphere from AKG are wireless headphones
that provide surround sound with Dolby Digital Decoder. The
Hearo 888 Titan converts the analog input signal to digital and all signal
processing and transmission to the headphones take place in the digital
The Hearo 999 features inputs for digital signals. All audio signal
processing is performed in the digital domain at a resolution of 24 bits.
Up to now, the Hearo 999 is the only device combining digital IVA for simulating
virtual loudspeakers, Dolby Digital for playing back multichannel movie
sound and Digital Wireless for noise-free surround sound transmission to
With its high quality reproduction the Hearo 999 Audiosphere is also
an efficient tool for use in the studio as monitor system for recording
and mixing, overdubbing and playbacks as well as for rehearsal. You can
get the same monitor quality for every mixdown, independent of control
room acoustics. The Hearo 999 Audiosphere eliminates the cumbersome wiring
needed for overdubs and playbacks and prevents ground loops. As many wireless
headphones as required can be used for overdubs. Digital signal ensures
interference-free transmission. For rehearsals, using ACS, a transmission
technique with almost zero delay (<5 msecs.), and IVA processing, the
Audiosphere provides a virtual acoustic environment to compensate for poor
rehearsal room acoustics.
The integrated Dolby Pro Logic and Dolby Digital decoders make the
Hearo 999 Audiosphere a suitable monitor system for future DVD projects.
It eliminates the need to set up a complex surround speaker system and
allows listening independently from any position exactly as it will be
heard on the DVD.
The Hearo 999 Audiosphere lets you listen to both conventional stereo
and five-channel Dolby Digital mixes from DAT or mini disc. Just record
the processed binaural headphone signal of the Hearo 999 Audiosphere on
DAT or mini disc and you can listen surround sound everywhere, anytime.
