[Product Description] Title: AVIOT Wireless Earphones TE-D01d Navy Manufacturer: AVIOT Description: ● JAPAN TUNED: More Japanese sound. Based on the award-winning previous model, AVIOT's audio expert team spent a great deal of time tuning in 0.1dB increments. Unlike many overseas products that simply boost a portion of the low frequencies and use "tricks" to stimulate the auditory sense more than necessary, we aimed for original sound reproduction with the same philosophy as high-end audio, pursuing Japanese sound directly. ● Equipped with the latest SOC Qualcomm QCC3026: Power-saving, and boasting overwhelmingly high DA (Digital to Analog) conversion performance, the latest SOC QCC3026 is adopted. We carefully selected the best speaker drivers from lightweight and high-speed graphene diaphragm drivers, achieving a deep, immersive low-frequency range, a mid-range that produces beautiful vocals with excellent sound image localization, and a high-frequency range that is clear and doesn't pierce the ears. ● Up to 9 hours of stamina playback: Combining the aforementioned power-saving chip with AVIOT's design know-how, we have achieved up to 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: Utilizing advanced high-frequency circuit design technology and implementation know-how, we have further improved the built-in antenna. 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 train stations.
