Product Details from the Brand

The Performance series goes wireless

Ultrasone - SIRIUS Bluetooth Adapter


SIRIUS combines the excellent sound quality of the ULTRASONE Performance series with the wireless convenience and flawless sound transmission of aptX® Bluetooth.


Sound, unleashed
Our Performance series enjoys an excellent reputation in the headphones market. The desire for a wireless model led us to an innovative new development: SIRIUS. Instead of enhancing the Performance series with just one new model with Bluetooth technology, we have developed a module that turns every set of headphones in the Performance series into Bluetooth headphones. Simple remove the cable from your Performance – and attach the SIRIUS instead. And just like that, you can enjoy your music via Bluetooth aptX® with full freedom of movement.


Perfectly matched
SIRIUS is designed to fit Performance series headphones exactly. Its strongly curved shape follows the design of the headphones and thus clings precisely to their housing. You won’t be able to tell that a SIRIUS module is docked onto the headphones. One of the reasons it is so inconspicuous is its extremely low weight: SIRIUS weighs just 12 grams – so Performance headphones remain as comfortable to wear as ever.


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.
