THE CULT OBJECT
The DT 990 Premium over-ear headphones have been winning the hearts of countless Hi-Fi and music enthusiasts since the 1980s

The DT 990 Premium comes in an open back design. This means that background noise outside the headphones remains clearly discernible even at higher volumes. This design lends the music a feeling of a wide soundstage, an appreciation of space that gives almost the same sense of enjoyment as listening to music with loudspeakers. The sound is spectacular. Distinctive highs and intense bass combine to produce a perfect richness of sound that delights rock and pop enthusiasts in particular.

Moreover, the PRO version is supplied with a coiled cable and the Premium version with a straight cable.

What is the Rockbox?

• The Rockbox can play for 24 hours straight! Its’ 6000 mAH battery is 500% stronger than most our competitors.
  
• The loudest 6.5” battery-powered Bluetooth speaker on the market
  
• No distortion even with the volume and bass turned to the max!
  
• The Rockbox is a multi-purpose speaker that is light-weight, portable, and good looking.
  

Rockville designers, engineers, and product development managers spent 6 months developing the all-new ROCKBOX. We developed what we consider to be the best combination of portability and sound. The ROCKBOX is an extremely light-weight and portable Bluetooth speaker that has amazing sound and an amazing battery life.

Pure sound!
The ROCKBOX has 100 watts of power! The most impressive thing to me about this speaker is the sound quality! The bass is incredible! I compared this against a $300 home theater speaker and this had way better bass! The highs are also crystal clear. To really test this speaker hard, I turned the volume up 100% to the max, turned the bass up 100% to the max and played some bass-heavy rap songs, and all I can say is wow! There was no distortion at all! Even when maxing this thing out the music is loud and clear with no distortion! When I say loud, I am not exaggerating. At top volume you are likely to hear complaints from your neighbors.

Battery life
I personally have been testing our prototype for the last 4 months and I only had to charge it twice so far. The battery life is incredible. Most speakers have a 1200 mAH battery. Our model has a 6000 mAH rechargeable lithium battery!

Playback options
The ROCKBOX has a top of the line Bluetooth module built in. The Bluetooth range is around 65 feet. Once paired for the first time it will auto pair to your phone in under 5 seconds from when you turn the unit on. The Bluetooth volume level is excellent and the sound quality is excellent in Bluetooth mode or any other mode.

The USB input allows you to play back your songs stored on a thumb drive. You can also connect an MP3 player or other USB device to the speaker through the USB.
The SD card slot allows you to play back songs stored on an SD card.

There is also a 3.5MM auxiliary input to connect a phone or other audio device. You can also use the aux input to connect this to your computer or laptop.

We also added an FM radio. The radio will only work when you plug an aux cable into the aux input. The aux cable acts as an antenna to get you radio reception.

Mic input with echo!
We added a mic input with a separate volume control and echo control making this speaker perfect for karaoke, speeches, and more.

Rugged and tough!
The enclosure is very rugged. It is made of high-grade ABS molded plastic. It can get thrown around without getting damaged. It has a carry handle making it easy to take with you on the go. The light-weight design makes this perfect for on-the-go applications. As you can see we brought you guys a funky and cool design to match the awesome sound.
