Portable devices have improved practically in every way except one – sound quality. It’s a question of as to how the listener hears the sound of their music or audio books through their headphones. The multinational companies are as decisive as to how perfect their processors are, or the high definition provided by the screen. Further they talk about how powerful the OS is accompanying which is the Lightweight and Sleek Dimensions.
It doesn’t matter if you purchase a top-of-the-line headset, if the sound entering into those headphones is poor in the first place. Why is sound from your mobile device so poor (at least from the standard of an audiophile)? Audio files on your computer are like any other files – they are binary, 1s and 0s. It requires a “digital to analog/audio” converter (otherwise known as DAC) to turn those files into sound that you can hear.
Portable device manufacturers (smartphones, tablets, laptops) use the most basic, internal DACs possible, because DACs drain the device’s battery.
So, while headphones have improved, that improvement does you no good if you use them through the headphone jack/DAC of your device. That’s why OnBlink has created the OnBlink Mini Amplifier and the OnBlink Plus Digital to Analog (DAC) Converter and Amplifier.
The OnBlink Mini Amplifier and the OnBlink Plus has to be plugged into the headphone jack of your device. The Amplifier will amp up the sound to a great extent. The OnBlink Plus Digital to Analog (DAC) converter will deliver amazing sound quality that you just don’t hear from the device’s internal DAC.
The size of your headphones dictates, to some extent, whether an amp may be needed. Most earbuds and in-ear headphones are typically very efficient and are less likely to have any benefits from an amp. Larger headphones, on the other hand, will benefit, or even require, a headphone amp to reach audible volume levels with portable players.
We have created a supply unit which can split output power far more stably in headphones. Other amplifier divide the power when connected with 2 headphones, but we designed 2 power lines to both the output jack which helps OnBlink mini and OnBlink plus to achieve incredible level of performance even when both the headphones are connected. Large size amp which are used for concerts have been using such technology from years, but this is the first time such a technology is introduced in such a portable size. This technology helps to run both the headphones of their maximum ohm.
Onblink plus uses the same outer body like many other amplifier in the market and there is a reason for that. That uni-body design helps to completely seal the chip of the DAC+AMP which does not interferes with portable device antenna. We noticed a sound interferance and disturbance in headphone before every incoming calls, that sound was the DAC getting affected by the portable device antenna. Hence we decide to use a uni-body design which completely isolates the chips from the reductions of the antenna. Few other reason pushed us to use the design was its compactness, durability and elegancy. This design also fits in our size of Advanced circuit and has ample of space to fit in a huge Lithium-ion batteries. This outer body which is readily available also brings down the cost exceedingly thus reducing the production delay altogether.
Other companies only have AMP in such a small and compact size. As we used Advanced circuit design using the latest IC technology, we could fit both the DAC and AMP in Onblink Plus. This has completely changed the Audio industry and has exceedingly enhanced your hearing experience. We have invested 2 years just to refine Onblink plus.
Onblink is the world’s smallest AMP + splitter, we have created a custom circuit for maximum performance, this changes the complete audio output circuits. We have successfully placed an audio chip TI OPA 1612 in such a small chamber. This technology would be hard for counterfeiter to even try. This took us a lot of time and resources to produce the Onblink mini which is a completely new design.
Research and development of the OnBlink Mini and the OnBlink Plus is complete.
The funds received will be used for production, packaging and marketing.

OnBlink is a audio consultancy - was established in 2012 with the aim of creating high end and detailed music ambience. OnBlink has successfully given audio consultancy for series of music shows in London, to become the bestselling audio assistance provider for any musical concert! We have worked closely with many music artist and brands for their shows and seminar.
Having owned this larger space of music, we have set our foot on this new mission to bring you quality music to your ears! Today In this world of advanced technology , where power back ups are owned by almost every individual, do you know that the power supply to the audio jack is limited by these back up devices? Did you know that the supply to you audio jack does not match the specifications required by your head gear? We are here to help you to understand audio output, the way we understand it.
we have more then 20 prototype before we came up with advance IC unit. This is a groundbreaking technology in AMP and DAC. For year the chip model was not changed, until now.
If you can't contribute monetarily, but like what you see. Tell your friends about these amazing little AMP+DAC . Share it on Facebook, twitter, your favorite forum, we would greatly appreciate and accept any help you have to offer.

Risks and challenges
We know great quality is hard to find, and with this project we cannot afford having bad quality components. That’s why we will manufacture it in UK to ensure only the best materials are being used. Any hardware project is a challenge so producing and shipping OnBlink out into the world won't be easy. We've spent considerable time assessing the potential risks, such as delays in component sourcing, issues with the process compatibility testing or fulfilment. Through understanding these processes we have strategies in place to keep the the project on time. Therefore we're confident that when we will face the challenges that inevitably come our way, we will be prepared to tackle them head on.
The reason we are shipping units in a small initial batch and a second larger one is so that we can ensure the highest quality for our backers. Assembling and shipping the first batch means we can ensure all the parts meet our spec and so we can make changes to manufacturing processes. We are confident that this is the best way to get the products to you as soon as possible.
Since QA is such a major focus for us, we’ll be testing components and subassemblies multiple times during the assembly process. Although this adds a little bit of time, it also ensures a robust product that can withstand you putting it through its paces for many years.Learn about accountability on Kickstarter
