As the successor to the popular “E500” wired earphones – a staple of [final]’s ASMR-dedicated line – this is the world’s first truly wireless ASMR earphone, the COTSUBU for ASMR, with further evolved sound quality.
・ASMR-Dedicated with “Proximity 3D Sound Field”: The sound field outside the head is reproduced with clarity, allowing you to feel a sense of realism as if you were actually in that space.
・Latest 2025 Model: The latest model has been upgraded to an optimal chipset to further improve sound quality. This allows you to enjoy a more refined sound. Please note that it is not compatible with the aptX codec supported by the version released in March 2024. We have designed it to continue to provide a high-quality sound experience, so please experience the new evolution of sound.
・Ultra-Small and Ultra-Lightweight: The earphone body is a compact type, weighing approximately 3.5g per side – the smallest and lightest in the series. The fit is so “light” you’ll forget you’re wearing them.
・High-Quality Sound Specification Supervised by Audio Brand [final]: Backed by research and technical expertise, it achieves both powerful bass and clear vocals, delivering a relaxed and natural sound quality that you’ll want to listen to every day.
・Instructions for Use: To ensure the long-lasting enjoyment of the product, please refer to the instruction manual regularly for cleaning and maintenance.
・Bluetooth connectivity depends on the environment, paired device, and system compatibility. Radio interference is more likely to occur in crowded places.
・Three sizes of ear pieces are included, so please replace them with the size that fits your ears.
