[Product Description] Title: AVIOT Wireless Earphones TE-D01d Red Manufacturer: AVIOT Description: ● JAPAN TUNED: More Japanese sound. Based on the award-winning previous model, AVIOT's audio expert team spent a lot of time tuning in 0.1dB increments. Without using "tricks" like simply boosting a part of the low frequencies like many overseas products and stimulating the auditory sense more than necessary, we aimed to reproduce the original sound with the same philosophy as high-end audio, and pursued Japanese sound directly. ● Equipped with the latest SOC Qualcomm QCC3026: The latest SOC QCC3026 is adopted, which is power-saving and boasts overwhelmingly high DA (Digital to Analog) conversion performance compared to conventional models. We carefully selected the best ones from the speaker drivers that use lightweight and high-speed graphene diaphragms, and achieved a deep, immersive low-frequency range, a mid-frequency range that plays beautiful vocals with excellent sound image localization, and a high-frequency range that is clear and does not pierce the ears. ● Up to 9 hours of stamina playback: By combining the aforementioned power-saving chip with AVIOT's design know-how, we have achieved a maximum of 9 hours of continuous playback with the earphones alone, despite the small and lightweight body. *Playback time may be shorter when using the higher-quality aptX codec, or depending on radio wave conditions and volume. ● AVIOT connects more: We have further improved the built-in antenna by utilizing advanced high-frequency circuit design technology and implementation know-how. The synergistic effect with the latest SOC OCC3026, which is extremely resistant to interference, has succeeded in minimizing sound interruptions even in places with harsh radio wave environments, such as inside trains and station premises.
