grell True Wireless Headphones Make High-Quality, Personalized Listening Experiences Accessible, Nurturing a New Generation of Digital-Age Audiophiles

Hannover, Germany, Oct 06, 2021 — grell, founded by renowned German headphone engineer Axel Grell, announces the debut of a brand-new line of true wireless headphones with the grell TWS/1 ($199.99 USD). The new in-ear headphones deliver audiophile-grade sound quality for consumers who crave crystal clear, transparent audio and a closer connection to their music, with a direct-to-consumer sales model designed to deliver a personalized, high-end listening experience to a new generation of users — so that the price reflects the Grell-designed sound-quality, alone.

An exclusive version of the grell True Wireless headphones — the drop + grell tws.01 — will be available via, in November following an initial pre-sale period on

Featuring an all-black finish, distinguished from the space-grey TWS/1 version — which will be available following the international product launch — US customers who purchase the drop + grell tws.01 version will also receive additional blue wingtip options for an even more personalized and secure listening experience.

grell in-ear headphones mark a pioneering step forward in the realm of high-end listening devices, providing a unique combination of high-quality technological components, German design, and meticulous attention to detail. The result is a stunning sound-signature created expressly for a new generation of digitally connected listeners.

For over three decades, Axel Grell has crafted headphones designed to produce world-class sound — at times, with little-to-no regard for price consideration. Throughout his mission to enhance the clarity and transparency in the headphone lines he produced, Grell garnered a devoted following among members of the audiophile community for his close attention to detail throughout all parts of the manufacturing process, pairing high-quality components with cutting-edge product designs — until the 1990s, when his uncompromising pursuit to design the most neutral headphones possible catapulted him to legendary status among audiophile communities.

“I always try to create the best possible acoustical experience for the money, no matter the price point,” said grell Founder, Axel Grell. “With grell, we put our resources solely into achieving the best sound possible, emphasizing the acoustic experience of the product and providing audio that is fine-tuned to the user’s ear. With our focus on audio, alone, we carefully selected custom dynamic transducers, used the best chipset that is available, and the best sounding codecs, shipped directly to the consumer in simple, inexpensive packaging. And this is true for every pair of grell earphones — giving the user high-end quality, but not at a high-end price.”

Making audiophile accessible

Axel Grell continues his quest to make the world sound better through his bold, new product designs. The new grell true wireless headphones are a direct response to a growing new generation of audiophiles in the digital era who are looking to experience the ultimate transparency and clarity that headphones can offer — in a smaller in-ear form factor.

Featuring TWS/1 technology, custom 10mm dynamic drivers, 28-hour battery life (ANC on), and transducers with a tolerance of +/- 1 dB, Active Noise Cancellation (ANC) — plus, Axel Grell Noise Annoyance Reduction (NAR) technology — grell true wireless headphones boast minimalistic, industrial-style design, which contrasts the complexity and richness of the acoustic output, without sacrificing a comfortable fit.

Unlike any of the designer’s earlier endeavors, however, grell seeks with its business model to lower the cost for the end-user, ushering in the future of high-res audio through a sales model tailored toward the spending habits of digital age listeners looking for opportunities to save money on high-end products without sacrificing quality for price. Sold directly through the company’s website and through an exclusive pre-order release on, grell’s online-only sales model seeks to remove some of the economic barrier-to-entry for budding audiophiles, and to nurture the next generation of sound for tomorrow’s listener.
