Wireless with optimum sound The Performance series’ sound quality is undisputed. High-quality drivers and S-Logic® technology ensure perfect sound transmission. SIRIUS makes no compromises, and uses the aptX® Bluetooth codec for highest quality, lossless audio streaming. Every model in the Performance series can be converted into a set of premium Bluetooth headphones using SIRIUS – but it is still possible to switch back to wired transmission at any time, for example for use with devices that are not Bluetooth enabled.
Perfectly amplified In addition to its function as a Bluetooth receiver, SIRIUS also integrates a headphone amplifier into its compact housing. This not only ensures that Performance headphones always have enough power; the specially adapted amplifier also provides the drivers with the perfect signal for an exciting musical experience.
Music headphones and headset SIRIUS has three buttons for operations. Two of them are for adjusting volume, while the third button can be used to play and pause playback. The integrated microphone even enables use of Performance headphones as a headset for making calls with a smartphone or tablet, or for wireless communication when gaming. Thanks to the high-performance battery, SIRIUS can be operated continuously for up to 12 hours.
