Final ZE500 for ASMR Wireless Earbuds, Ultra-Small, Recommended for Sleeping (Cream)

New sound quality design optimized for ASMR content: Final engineers leveraged the latest research in acoustic engineering and psychoacoustics to develop a new, ASMR-specific sound quality optimized for an ultra-close sound field. By positioning the sound image close to your ears, you'll feel as if you're inside the dummy head microphone, creating a truly immersive experience. Newly designed "ASMR port": Considering the fact that earphones are often used for extended periods of time, such as when falling asleep or watching streams, we developed a new "ASMR port." By adjusting the pressure buildup in the ear canal, it relieves strain on the eardrum while also reducing strain on the internal driver. It also reduces moisture buildup inside the ear canal, allowing for comfortable use even over long periods of time. Integrated soft earpieces for a comfortable fit: A comfortable fit with minimal pressure is essential for deep immersion in the world of the content. This product features a new "ultra-lightweight and extremely small housing" weighing approximately 3g per earphone, and newly designed "integrated soft earpieces" that encase the entire earphone body in silicone, achieving an ideal fit with zero pressure. Even when pressure is applied to your ears with a pillow or cushion, there's virtually no sensation of a foreign object. [Volume Step Optimization Function] Everyone's sense of appropriate volume varies, and we tend to be particularly sensitive to volume adjustments in quiet spaces, such as when sleeping. However, using a smartphone's volume controls can sometimes result in large volume increments, making it difficult to achieve the desired volume. This product's "Volume Step Optimization" feature in the dedicated app allows for easy, precise volume adjustments. [Other Convenient Features!] Supports wired charging (USB Type-C). Enjoy up to 4.5 hours of continuous playback with the earphones alone, and up to 18 hours with the case. Additionally, simply returning one earphone to the case and closing the lid automatically switches to "single ear mode" without interrupting the audio.
