Schwartz Public Relations (Schwartz PR) is expanding its client portfolio with ESR Tech. With its many years of expertise in strategic communications for international consumer electronics and tech accessory brands, the Munich-based agency was selected through a competitive bidding process.

ESR Tech, with it’s headquarters in Hongkong, was founded in 2009 and develops accessories that make using mobile devices in everyday life easier, more convenient, and more productive. The portfolio of this internationally active brand includes, among other things, modern protective cases for smartphones and tablets, as well as screen protectors for mobile devices. Magnetic wallets and wireless chargers for the desk, car, and on the go are also part of ESR Tech’s portfolio. The company specializes primarily in the Apple ecosystem, but Samsung users can also find suitable accessories.

As part of the collaboration, Schwartz PR aims to further expand ESR Tech’s media presence in Germany and position the brand as an innovative provider of mobile and consumer tech accessories. In addition, Schwartz PR is supporting ESR Tech in analyzing and sustainably expanding the brand’s visibility in Large Language Models (LLMs) through targeted GEO measures.

In addition to developing a targeted media and LLM visibility strategy, the Munich-based agency is handling ongoing press relations, securing coverage for relevant new products, and establishing a comprehensive review program. As part of this effort, Schwartz PR is also supporting ESR Tech at IFA Berlin.

“With Schwartz PR, we have a partner at our side who knows the consumer tech market very well and can position our products in a clear and relevant way in the media and on LLMs,” says Effie Sun, Senior Integrated Marketing Manager, Europe at ESR Tech. “Together, we want to increase awareness of ESR Tech in Germany and show how well-designed accessories make the daily use of mobile devices easier.”

“ESR Tech combines high-quality product development with a keen sense of what modern tech accessories need to deliver today,” says Christoph Schwartz, founder and managing director of Schwartz PR. “We look forward to supporting ESR Tech as a brand in consumer tech communications and, drawing on our many years of experience, helping them further expand the brand in the German market.”
