While most headphone brands compete on price, battery life, or smart features, Rapture Innovation Labs has taken a different route. Founded by Navajith Karkera and Jagath Biddappa, the Bengaluru-based hardware startup is focused on changing how people experience music through its flagship product, Sonic Lamb headphones.

Instead of relying solely on conventional audio drivers, Sonic Lamb combines traditional sound delivery with body-conduction technology, allowing listeners not only to hear music but also to physically feel bass and rhythm. The company’s research-driven approach has positioned it as one of India’s emerging deep-tech startups in the premium consumer audio segment.

Engineering Curiosity Sparked an Entrepreneurial Journey

The story of Rapture Innovation Labs began long before the company was founded.

As a child, Navajith Karkera developed a fascination with electronics by dismantling household gadgets to understand how they worked. Encouraged by his family, he experimented with electronics kits that nurtured his curiosity about engineering and product design.

He later pursued Mechanical Engineering, while his future co-founder Jagath Biddappa studied Electrical Engineering.

The two engineers met during their academic years and bonded over a shared interest in acoustics, vibration systems and the science behind human interaction with sound.

From Safety Technology to Consumer Innovation

Their earliest engineering work was not intended for entertainment.

Initially, Karkera and Biddappa focused on developing hearing assistance systems and audio communication technology for industrial safety helmets. These solutions used bone and skin conduction to deliver sound without blocking the user’s ears, helping improve communication in hazardous work environments.

As their research progressed, they recognized that conduction-based sound technology could also transform personal audio experiences.

By 2019, they began adapting their technology for consumer headphones, aiming to create an entirely new way of listening to music.

The Birth of Sonic Lamb

The result of their research was Sonic Lamb, the company’s first commercial product.

Unlike conventional headphones, Sonic Lamb features a patented hybrid driver system that combines:

• Air conduction
• Body conduction

Traditional air conduction delivers sound through the ear canal, while body conduction transfers vibrations through physical contact with the user’s body.

Instead of increasing volume to emphasize bass frequencies, Sonic Lamb distributes the listening experience between hearing and touch, allowing users to physically sense low-frequency vibrations.

The founders believe this approach delivers a more immersive listening experience while reducing ear fatigue during extended listening sessions.

How Sonic Lamb Works

Conventional headphones rely exclusively on speakers positioned near the ears.

Sonic Lamb introduces a second audio pathway.

Its body-conduction technology transmits vibrations through the skin and skeletal structure, creating a sensation similar to standing near live speakers without requiring excessive listening volume.

The system provides users with insights into music that extend beyond audible frequencies by adding tactile feedback.

According to the company, this technology is particularly effective for:

• Bass-heavy music
• Live recordings
• Gaming
• Cinematic entertainment
• Immersive audio experiences

Rather than replacing professional studio equipment or home speaker systems, Sonic Lamb is designed to offer a distinctive personal listening experience.

Targeting Premium Audio Enthusiasts

Priced at approximately ₹15,999, Sonic Lamb is positioned within the premium headphone category.

Instead of competing in India’s highly competitive budget audio market, Rapture Innovation Labs focuses on customers who prioritize engineering innovation and sound quality.

Its target audience includes:

• Audiophiles
• Musicians
• Content creators
• Audio professionals
• Long-duration headphone users

The founders have intentionally emphasized product differentiation over mass-market expansion.

Building a Technology-First Brand

India’s consumer audio market is dominated by brands competing through aggressive pricing, marketing campaigns and incremental feature additions.

Rapture Innovation Labs has adopted a different philosophy.

According to the founders, many consumer electronics companies have shifted their attention toward branding while investing comparatively less in fundamental improvements to sound reproduction.

By concentrating on engineering research, intellectual property and hardware innovation, the startup aims to establish itself as a technology-led audio company rather than a volume-driven consumer electronics brand.

International Recognition

The company’s innovative approach has earned recognition beyond India.

Rapture Innovation Labs was selected for the SoundTech Accelerator Programme organized by Sound Hub Denmark, an internationally recognized innovation hub supporting advanced audio technologies.

Only a small number of startups from around the world were selected for the program.

Participation provided the founders with access to:

• Advanced acoustic laboratories
• European sound engineers
• Product testing facilities
• Industry mentors
• Hardware development expertise

The exposure helped further refine Sonic Lamb’s technology for international markets.

Institutional Support

Beyond international accelerator programs, Rapture Innovation Labs has received support from several prominent Indian startup and innovation organizations, including:

• Deshpande Startups
• National Institute of Design (NID)
• T-Hub
• SINE, IIT Bombay
• Angel investors

These organizations have supported the startup’s efforts to commercialize advanced consumer hardware based on proprietary technology.

Strong International Demand

Although headquartered in Bengaluru, Rapture Innovation Labs generates a significant portion of its sales internationally.

According to the founders, nearly 60% of Sonic Lamb sales originate from the United States.

The stronger overseas demand reflects growing consumer interest in premium, experimental audio technologies where buyers often prioritize product innovation over price.

Industry Response

The product has also attracted attention from experienced professionals within the audio industry.

Among those who have acknowledged the founders’ engineering-led approach is Ratish Pandey, former General Manager at Bose Corporation, who has highlighted the company’s emphasis on rigorous testing and product refinement before commercialization.

Such recognition underscores the importance of engineering credibility in a market frequently driven by branding and marketing.

Expanding Beyond Music

While Sonic Lamb was initially designed for music enthusiasts, Rapture Innovation Labs is exploring additional applications for its technology.

The company is evaluating opportunities in:

• Gaming
• Virtual reality (VR)
• Extended reality (XR)
• Interactive entertainment
• Immersive media experiences

These sectors increasingly rely on tactile feedback to create more engaging user experiences, making body-conduction technology a promising area for future innovation.

Looking Ahead

Rapture Innovation Labs continues to focus on improving product quality, manufacturing consistency and software optimization across multiple devices and audio formats.

Rather than pursuing rapid expansion, the founders have chosen a measured growth strategy centered on research, product refinement and long-term technological differentiation.

Their roadmap includes strengthening international distribution while continuing to invest in advanced audio engineering.

A Different Vision for Consumer Audio

In an industry where many products compete through cosmetic upgrades and incremental features, Rapture Innovation Labs represents a hardware-first approach driven by original engineering.

For Navajith Karkera and Jagath Biddappa, success is not defined by producing louder or cheaper headphones, but by fundamentally changing how people experience sound.

As immersive technologies continue to evolve, innovations like Sonic Lamb suggest that the future of personal audio may extend beyond hearing alone—transforming listening into a multisensory experience that combines sound with touch.
