Headphone Zone Certified Unboxed Units
Unboxed units are as good as new products with the product's packaging being unavailable. These products give you the same satisfaction of new products - but at down-to-earth prices. Usually, the product's packaging may have gotten damaged in transit. Customers use a product once or twice and then return it with opened up packaging.
Returned headphones are fully functional products that have left the warehouse and therefore can no longer be sold as new as their packaging has been opened. The product may have been used once or twice by the customer who returned it.
Sometimes we receive headphones in damaged packaging due to shipping accidents. These are brand new headphones with cosmetic flaws on the packaging.
Save Upto 15%Since you won't get the original packaging, we give you a good discount compared to a new headphone.
Professionally InspectedA thorough inspection means you receive a 100% working headphone with no sound output issues.

Wireless Sound UnleashedIn the headphone market, Ultrasone Performance series has an excellent reputation. SIRIUS lead Ultrasone to innovative design to make the headphone wireless. With SIRIUS, we can make all the Performance series headphones into Bluetooth headphones by removing the cable and attaching the SIRIUS.
Perfectly Matched for the Performance Series
The SIRIUS is designed to fit the Performance series headphones exactly. It has a curved shape that nicely fits into the Performance 820, 840, 860 and 880 headphones seamlessly. You won't be able to tell that a SIRIUS module is docked onto the headphones. It has such a low weight that it doesn't add any bulk to your Ultrasone headphones. At just 12 grams your Performance headphones remain as comfortable to wear as ever.
Undisputed Wireless SoundUsing the aptXå¨ Bluetooth codec for the highest quality, lossless audio streaming, the SIRIUS is a no-compromise Bluetooth adaptor. All headphones in the Performance series can be converted into a set of premium Bluetooth headphones using SIRIUS. In case you want to use your cables instead, when Bluetooth devices are not around, you can simply go back to the wired transmission mode.
Not just a Bluetooth Adapter, but an Amp too!
We're serious, the Ultrasone SIRIUS is not just a Bluetooth adaptor. In its tiny housing, Ultrasone has managed to squeeze in a headphone amplifier. This amplifier's sole purpose is to give the Performance drivers the ultimate signal for an enthused listening session.
Control your Music & Calls with the SIRIUSWith three buttons for operations, the SIRIUS is intuitively designed. Two of them are for adjusting volume, while the third button can be used to play and pause playback. Surprisingly the SIRIUS also includes an integrated mic so that you can turn your Performance headphones into a headset. Now you use your Ultrasone headphones with your smartphone, tablet or even wireless communication while gaming. Continuously use the SIRIUS with your headphones for up to 12 hours.
