Radius Earphones Open-type casual/sports, products from Japan

Carbon fiber dome diaphragm driver "Carbon fiber dome diaphragm" is adopted as the dynamic driver to be installed. By attaching carbon fiber paper with a thickness of only 75 μm, which is highly rigid, lightweight, and has excellent dimensional stability, to the dome of the PU diaphragm, an ideal balance between propagation speed and internal loss is achieved. The supple stroke performance of the carbon fiber dome and PU edge achieves both rich bass without incidental sounds and delicate mid-high range. Furthermore, by installing a CCAW (copper clad aluminum wire) voice coil, which is than ordinary copper wire, and a high magnetic force magnet of N45, it reproduces powerful and sharp deep bass with excellent transient characteristics.;Equipped with hybrid driver In addition to the carbon fiber dome diaphragm driver, it is equipped with a high-resolution, low-distortion, low-power ultra-compact BA driver to improve the reproducibility of the mid-high range. In order to fully demonstrate the hybrid performance, the crossover of the frequency response has been finely adjusted to realize an overwhelming sound field feeling and a dynamic dynamic range unlike any other TWS.;Equipped with new generation Bluetooth chip "QCC3040" Qualcomm's new generation model "QCC3040" is adopted as the core chip for Bluetooth connection. It supports "True Wireless Mirroring" and "aptX Adaptive Codec", and the stability of connection is significantly improved compared to the previous generation chip. In addition, it is compliant with the Bluetooth standard Ver5.2, and has the technology "LE Power Control *" that optimizes the left-right balance of the transmitted signal strength of earphones according to the received signal strength of the connected device, and multiple ATT protocols (operation control signals). ) Is transmitted in parallel to suppress communication delays and support the "Enhanced Attribute Protocol *" technology that improves responsiveness between devices. Furthermore, in terms of audio performance, THD + N, which represents the distortion factor of sound, has been improved by 6 dB compared to the previous generation chip, achieving excellent music reproducibility. * The connected device must comply with the Bluetooth standard Ver5.2.;Compatible with aptX Adaptive Codec The communication codec supports "aptX Adaptive" in addition to "SBC", "AAC" and "aptX". "AptX Adaptive" is Qualcomm's latest codec that realizes a stable connection at all times by changing the transfer bit rate of voice data in real time according to the usage environment. The transfer bit rate is variable in the range of 280kbps to 420kbps, and it can be played back with sound quality equivalent to 16bit / 44.1kHz CD at 280kbps and high resolution equivalent to 24bit / 48kHz at 420kbps. Since the delay time is short, you can enjoy not only music playback but also video viewing and games without stress.;Ambient sound mode Equipped with an external sound capture function that focuses on the human voice. You can instantly listen to conversations and station announcements without removing the earphones.
