Review Summary
Performance Series becomes wireless
SIRIUS combines the outstanding sound quality of the ULTRASONE Performance Series with the wireless comfort and flawless sound transmission of aptX Bluetooth.
Unleashed Sound
Our Performance Series enjoys a great reputation in the headphone market. The desire for a wireless model has led us to an innovative new development: SIRIUS. Rather than adding the qualities of the performance series to a new model with Bluetooth technology, we've developed a module that turns every Performance Series headset into a Bluetooth headset. You simply unplug the cable from your performance - and put the SIRIUS in its place. Already enjoy your music via Bluetooth aptX in complete freedom of movement.
Perfectly adapted
The design of SIRIUS is exactly tailored to the headphones of the Performance series. The strongly curved shape is based on the design of the headphones and therefore adapts precisely to their housing. If you do not know that a SIRIUS module is docked to a headset, you will hardly notice it. The enormously low weight contributes to this inconspicuousness: SIRIUS weighs only 12 grams - the wearing comfort of the Performance headphones is thus completely preserved.
Wireless with the best sound
The sound quality of the Performance Series is beyond question. The high-quality drivers and S-Logic technology ensure perfect sound transmission. SIRIUS makes no compromises here and uses the aptX Bluetooth codec for lossless audio streaming in the best quality. With SIRIUS, every model in the Performance Series can therefore be converted into a comfortable premium Bluetooth headset - decommissioning for wired transmission, for example for operation on non-Bluetooth-enabled devices, is, of course, always possible.
Optimally reinforced
In addition to its function as a Bluetooth receiver, SIRIUS integrates a headphone amplifier into its compact housing. This not only ensures that there is always enough power available for the performance headphones. The specially tuned amplifier also provides the drivers with the perfect signal for an exciting music experience.
Music headphones and headset
SIRIUS has three buttons for operation. Two of them form a volume rocker and adjust the volume, the third button starts or pauses the playback. An integrated microphone even makes it possible to use a performance headset as a headset for telephoning with a smartphone and tablet or for wireless communication during gaming. Thanks to the powerful battery, SIRIUS can be operated continuously for up to 12 hours.
