Japanese audio brand ONKYO, known for its frequent collaborations with various anime IPs, has previously teamed up with hits like Cosmic Princess Kaguya! and Mobile Suit Gundam Wing, both to great acclaim.
Now, they're back with a new collaboration, celebrating the 20th anniversary of the anime adaptation of the light novel series, "The Familiar of Zero"! Get ready for a special edition of their true wireless earbuds, featuring exclusive voice prompts from the main heroine, Louise (CV: Rie Kugimiya). These limited-edition buds are priced at 22,000 JPY and are currently available for pre-order on ONKYO's official website.
"The Familiar of Zero" is a light novel series penned by Noboru Yamaguchi (who sadly passed away from cancer in 2013, with Yuu Shimizu completing volumes 21 and 22), with illustrations by Eiji Usatsuka. The series gained massive popularity with its TV anime adaptation in 2006, largely thanks to Rie Kugimiya's iconic portrayal of Louise, who quickly became a fan favorite and a quintessential example of the Tsundere archetype in ACG culture.
The earbuds themselves are based on the "CP-TWS01F" model, boasting features like Active Noise Cancellation (ANC), a low-latency mode, and IPX4 splash resistance, making them super practical for everyday use and even gaming. Plus, they come in an exclusive, custom-designed package featuring brand-new artwork from the collaboration!
The charging case sports the anime's title logo, while the earbuds themselves are adorned with a magic circle design, subtly showcasing the series' unique world and elements.
But let's be real, the biggest draw here is undoubtedly the 16 exclusive voice prompts recorded by voice actress Rie Kugimiya. From power-on and connection confirmations to touch controls and battery level alerts, you'll be fully immersed in Louise's company every step of the way.
