The World’s Most Expensive Headphones Priced At Rs 45 Lakh.

German Audio specialist Sennheiser has added another crown to its line-up after its legendary $55,000 (~ Rs 35 Lakh) headphones ‘Orpheus’. This time, the company has taken it even further and is calling the release ‘the world’s best and finest headphones’ and they have named it the Sennheiser HE 1.

With such claims being made, you can bet that the new Sennheiser headphones are not your everyday headphones and that they just might be heavy on your pocket as well. But just how expensive are the new Sennheiser HE 1? Well, the German company has priced the “world’s best” headphones at a whopping Rs 45 Lakh.

And now you are left wondering, what exactly is going on here? You might understand the sound correctness, frequency response, amplifications and all the things required to make a headphone great but 45 Lakh?

Here is why the Sennheiser HE 1 beats the price barriers and the regular audio concepts known to many.

To start with, Sennheiser claims that the headphones deliver ‘a frequency response that extends beyond the range of human hearing’. As a result, the Sennheiser HE 1 have recorded ‘the lowest total harmonic distortion ever measured in an audio reproduction system’. Sennheiser claims to have brought the distortion down to 0.01 percent.

Daniel Sennheiser, CEO of the company, puts it in simple words “No other sound reproduction system in the world is able to deceive our senses like the HE 1. It creates the absolutely perfect illusion of being directly immersed in the sound,”

Amplifier Concept

– Sennheiser has put to use, an entirely new amplifier concept that combines a tube amplifier’s impulse processing with a transistor amplifier’s low distortion.

– Italian Carrara marble has been used to make the Amplifier housing to monitor the sensitivity to air-borne-noise.

– The cups of the headphones house a patented, ultra-high impulse amplifier stage.

– Sennheiser puts its new amplifier concept in Cool Class A, which provides Class A power at any volume in the low-frequency range and switches to Class AB in ultra-high frequency range.

– The amplifier and the diaphragm are placed less than 1 cm away, reducing the power requirement for charge reversal.

– A combined effect ensures high impulse fidelity with relatively low power requirements.


– The Sennheiser HE 1 constitutes of more than 6,000 individual components.

– Sennheiser HE 1 uses platinum-vaporised diaphragms and gold-vaporised ceramic electrodes.

– The eight wires of the cables are made of oxygen-free copper and silver plated for optimum transmission of audio signals.

– Also, the wires are covered with an insulating layer to eliminate any sound waves acting on the cable.


– Sennheiser HE 1 uses ESS SABRE ES9018 chip to convert digital music data into analog signals.

– HE 1 houses 8 internal DACs to convert audio data with 32 bits resolution and a sampling rate of up to 384 kHz into analog signals.

– 4 DACs are connected in parallel for each stereo channel for noise reduction.

Sound Experience

– The Italian Carrara marble used in the HE 1 is the same type of marble using which Michelangelo created his sculptures.

– A single piece of brass is used to make the rotary switches for the source and the volume controls which are also chromium-plated.

– A microprocessor is used to control the position of four switches.

– Each element follows the listener’s adjustments and can be remote controlled.

The HE 1 will be available in India from May 2017 for Rs 45,00,000.

German Scientists Turn On World’s Largest Artificial Sun For The First Time At 3500 Celsius

German scientists have just hit the ignition on what they’re calling the “world’s largest artificial sun,” in a series of experiments to develop better solar production technology.

Assembled earlier this year, ‘Synlight’ is an experimental setup designed to replicate the amount of solar energy the Earth is blasted with daily, in an effort to improve photovoltaic cells and other renewable sources of energy.

Being conducted in Jülich, the setup involves 149 short-arc lamps (film projector spotlights), each with roughly 4,000 times the wattage of average light bulbs. Scientists from the German Aerospace Center (DLR), intend to use Synlight to produce light about 10,000 times more powerful than natural sunlight hitting a single point on Earth.

The idea is that current solar panels are not capable of functioning at maximum efficiency. Synlight points all of its lamps at one spot with temperatures reaching up to 3,500 degrees Celsius, roughly three times hotter as a blast furnace. The research team plans to use the experiment to find cleaner and cheaper ways to generate energy, particularly how to use sunlight to produce hydrogen fuel cells. “We’d need billions of tonnes of hydrogen if we wanted to drive airplanes and cars on CO2-free fuel,” DLR’s Bernard Hoffschmidt told The Guardian earlier in March. “Climate change is speeding up so we need to speed up innovation.”

The experimental facility with its sealed radiation chamber

Of course, the experiment also comes with its own risks. “If you went in the room when it was switched on, you’d burn,” Hoffschmidt said. For this reason, the test is being conducted in a sealed radiation chamber. The experiment is also ludicrously expensive, capable of burning through as much electricity as a four-person household would use in a year, in just four hours. But the possible findings Synlight could yield are most certainly worth it.

Aside from renewable energy, Synlight could also be re-purposed in future to test the heat-resistance of rocket components, an issue of steadily escalating importance as space agencies around the world (both private and government-run) prepare for manned missions to Mars and beyond.

“Mumbai is home to a booming food industry with a vibrant food culture offering both global and local cuisines. The introduction of UberEATS in India, with Mumbai as the first city, is a major step in our global expansion and showcases our commitment to the region. The app brings the perfect pairing of amazing restaurant partners, innovative technology, and the efficient Uber delivery network at a tap of a button to people in India,” Bhavik Rathod, Head of UberEATS India, said.

With UberEATS app, users can view food photos as well as search for restaurants. The app uses machine learning to customise taste preferences, restaurants and dishes for individual users, based on their past orders. Another unique feature of UberEATS is that it offers the ability to schedule an order. Users can book deliveries anytime between up to an hour before the delivery window to a week in advance. Just like rival Swiggy, UberEATS lets users live track their order as well. Users can get their food delivered to customised locations including hospitals, parks and office buildings.

Remeber, UberEATS is a separate app and its services aren’t integrated in to Uber app. However, UberEATS uses the same technology as their cab service. There’s a delivery charge of Rs 15 on each order and no minimum order size. UberEATS is available for iOS and Android users on App Store and Play Store respectively.

To start using UberEATS, first download the app. Next, enter the address where you’d like your food delivered. You can browse by restuarants, price, cuisine type as well as speed. Now place order. You can choose items that you want delivered right away or schedule order for later. UberEATS allows users to pay via PayTM, which is their launch partner. Users can live-track their order via UberEATS.

UberEATS was rolled out as a delivery pilot in Los Angeles in 2014. The stand-alone app is now available in 26 countries and in 78 cities around the world. In India, UberEATS will face competition from the likes of Zomato and Swiggy, which are already quite popular as food delivery services. The challenge for UberEATS will be to offer something new in terms of service and UI as against those already present in this space.
