Baseus Chooses Knowles Balanced Armature Drivers for Groundbreaking Open-Ear Clip Wireless Earbuds, Baseus Inspire XC1

Baseus becomes the first brand to integrate Knowles' Balanced Armature technology in wireless open-ear design, delivering superior audio clarity and all-day comfort in a hybrid configuration. 

ITASCA, IL, Sept. 5, 2025 — Knowles Corporation (NYSE: KN), a leading manufacturer of specialty electronic components, including high performance capacitors, radio frequency ("RF") filters, advanced medtech microphones, and balanced armature (BA) speakers, today announced that Baseus has selected Knowles BA drivers for its flagship open-ear clip wireless earbuds, the Baseus Inspire XC1. This marks the first time Knowles BA technology has been integrated into an open-ear wireless design, representing a significant breakthrough in personal audio innovation.

Revolutionary Hybrid 2-Way Sound Engine

The Baseus Inspire XC1 features a pioneering hybrid 2-way sound engine that pairs a Knowles BA with a 12mm dynamic driver in each earbud. This distinctive combination addresses longstanding acoustic challenges in open-ear designs while delivering crystal-clear sound that rivals traditional in-ear models. Tuned with Baseus's adaptive SuperBass 3.0 technologies, these open-ear headphones deliver full-range, high-fidelity sound—just as the artist intended. This distinctive combination addresses longstanding acoustic challenges in open-ear designs while delivering crystal clear sound that rivals traditional in-ear models.

Open-ear wireless devices sit outside the ear canal, allowing ambient sound to naturally coexist with the audio experience while providing benefits such as comfort during extended wear, reduced occlusion effect, increased battery capacity, and enhanced situational awareness. However, open-ear designs have historically faced acoustic challenges, including sound leakage, low-frequency drop-off due to a lack of seal, and difficulties in delivering full-spectrum audio.

The Inspire XC1 overcomes these limitations through its sophisticated acoustic system, which combines the precision of Knowles' miniaturized BAs with the power of a 12mm dynamic driver. This results in a frequency response that captures both subtle sonic textures and a dynamic range that single-driver designs cannot achieve. The dynamic woofer enhances low-frequency response, while the exclusive Knowles BA tweeter delivers exceptional clarity in the mid and high frequencies.

"This collaboration represents a significant milestone for both open-ear wireless audio and our BA technology," said Jon Kiachian, President of MedTech and Specialty Audio at Knowles Corporation. "This is the first time our BAs have been integrated into an open-ear design, and Baseus has demonstrated remarkable innovation in addressing the unique acoustic challenges of this format. The result showcases exactly what becomes possible when our cutting-edge driver technology meets thoughtful product design—an open-ear audio experience that reveals all the nuances and details of music that conventional open-ear designs simply cannot reproduce."

Designed for Every Lifestyle

These revolutionary earbuds are ideal for users who want to listen to music while remaining aware of their surroundings. Whether you're working out at the gym, taking phone calls while walking the street, snowboarding, or skating with music, wearing a clip-on earbud all day at the office for quick calls, or working and studying in a coffee shop, the Baseus Inspire XC1 delivers uncompromising audio quality without sacrificing situational awareness.

 Knowles BA drivers enable unprecedented sound performance for their size, allowing Baseus to deliver professional-grade audio quality while maintaining the comfort and situational awareness benefits that make open-ear designs appealing to tech-savvy professionals. The high sensitivity of Knowles BAs also facilitates improved hearing personalization while maximizing power efficiency in the compact form factor.

 The Baseus Inspire XC1 leverages Knowles BA technology to achieve the higher frequencies necessary for optimal audio performance, unlocking intricate musical details while preserving natural tonal balance. Advanced features include Dolby Spatial Audio, Hi-Res certification, LDAC codec support, and a leak-proof acoustic design that positions the earbuds among the world's best-sounding open-ear audio devices.

"When developing our Inspire XC1 open-ear clip model, we needed a technology partner that could help us solve fundamental acoustic challenges that have limited this category," said Shiyou He, Baseus Founder and CEO. "Knowles BA drivers were the breakthrough we needed, allowing us to achieve frequency response and detail that would be hard with conventional single-driver open-ear designs. This collaboration enables us to create the first open-ear earbuds that can compete with premium in-ear models on audio quality."

The Baseus Inspire XC1 open-ear clip wireless earbuds featuring Knowles BA technology were unveiled ahead of IFA and are available through the Baseus US official website, Baseus DE official website, Amazon U.S., Amazon DE and Amazon UK.  For more information on Knowles BAs, visit www.knowles.com/premiumsound.
