Hiiro Tsurugi Voice Included Collaboration Wireless Earphones ONKYO Wireless Earphones CP-TWS01E Brand new, unopened. ↓ Quoted from the following site ↓ This model, "CP-TWS01E," uses the Qualcomm (R) SoC "QCC3072." In addition to the general SBC and AAC, it also supports the latest audio codec, Qualcomm (R) aptXTM Adaptive. By combining it with the latest compatible Android devices, it achieves higher sound quality, lower latency, and higher connection maintenance performance compared to the conventional Qualcomm (R) aptXTM. Furthermore, it is equipped with "Qualcomm (R) TrueWireless Mirroring," which enables high-quality simultaneous left and right connections with iPhone, Android devices, and music players. This technology connects one earphone as the parent device and sends the signal from the opposite side to the other earphone while mirroring it. By constantly performing role swapping to prevent transmission loss of audio signals, it suppresses sound interruptions and noise, and prevents uneven battery drain. It also features ANC (Active Noise Canceling) function, external sound capture (ambient mode) function, and low-latency mode (game mode) function. In addition, it is equipped with a waterproof function (IPX4), so you can use it with peace of mind even during exercise or sudden rain (excluding the charging case). This model features newly recorded voice guidance (13 words in total) by Hiiro Tsurugi. The top of the charging case and the earphone body feature an original design inspired by Hiiro Tsurugi, and the package uses an illustration drawn specifically for this model. Due to being unopened, we do not handle initial defects or initial scratches. Thank you for your understanding. m(_ _)m Please feel free to ask if you have any questions. ☺︎
