Kenwood launches Glass Core and Glass Core Pro ANC wireless earbuds with glass diaphragms in Japan
Kenwood has introduced the Glass Core series of ANC wireless earbuds in Japan, featuring glass diaphragms to reproduce music with high transparency, wide frequency coverage, and spacious expression while suppressing unwanted vibration, according to the company. The launch coincides with the company’s 80th anniversary, positioning them as a premium offering.
The series includes two models—the Glass Core (KH-CRZ90T) and the Glass Core Pro (KH-CRZ100T)—both supporting high-resolution audio via the LDAC Bluetooth audio codec, in addition to standard SBC and AAC audio codecs. The former uses a 10 mm glass diaphragm, while the latter adds a MEMS driver to enhance high-frequency sound reproduction.
To reduce external noise, both models use newly developed liquid silicone eartips, with improved sealing when inserted into the ear canals. The Glass Core model comes with active noise cancellation with wind noise reduction and AI background call noise reduction. The Pro model features the company's most advanced adaptive ANC technology.
The Pro model further enhances spatial performance with Exofield technology, which simulates the localization and spread of sound as if played through room speakers. Additionally, this model uses K2 Technology to upscale low‑resolution audio by restoring lost high‑frequency components in compressed music sources.
The Glass Core has an MSRP of 27,800 yen (~$170), while the Glass Core Pro retails for 49,900 yen (~$300). Both models are available through Kenwood Japan's website, with shipping scheduled to begin in late June 2026.
