Kenwood - KH-CRZ90T - Glass Core True Wireless Earbuds
The Kenwood GLASS Core KH-CRZ90T true wireless earbuds celebrate Kenwood's 80th anniversary with an industry-first glass diaphragm developed to deliver the company's philosophy of faithful original sound reproduction. The rigid glass diaphragm helps suppress unwanted vibration while reproducing information across a wide frequency range, creating a spacious presentation with clarity, sharp attack, and natural musical detail. Unlike the GLASS Core Pro's two-way driver architecture, the GLASS Core uses a streamlined single 10mm glass-diaphragm driver.
High-performance noise cancellation helps create a quieter listening environment during travel, work, and everyday use, while Adaptive Mode can automatically adjust cancellation strength according to surrounding noise. Wind Cut mode helps reduce wind interference outdoors, and newly developed liquid silicone eartips provide a flexible, secure seal designed to improve isolation, reduce leakage, and maintain comfort. LDAC support enables high-resolution wireless playback from compatible devices, while AI Noise Reduction helps keep voices clearer during calls.
The GLASS Core is designed for everyday flexibility with app-based sound and control customization, eight selectable sound modes, two-device multipoint connectivity, Natural Ambient Sound Mode, and Low Latency Mode for video and gaming. Wireless charging, quick charging, an Earbud Locator function, and independent left or right earbud operation add convenience, while IPX4 water resistance helps protect the earbuds during active daily use. Its smaller earbuds and compact charging case also distinguish GLASS Core as the more streamlined option in Kenwood's new glass-diaphragm range.
