Purchased September 2025, used a few times. - Brand: Audio-Technica - Color: White - Type: Wireless Earphones - ATH-AC5TW WH The liberating feeling of not covering your ears, the excitement of enjoying what you love. "While-listening" earphones for those who care about sound. ■ Enjoy rich sound without covering your ears The ideal driver movement is brought out by the acoustic technology of a Japanese audio manufacturer with over 60 years of history, reproducing rich sound. It employs a large 17x12mm oval driver, an acoustic space that controls airflow, and an acoustic duct. ■ Reinforces the low frequencies and reproduces sound with a sense of volume You can enjoy well-balanced sound with a sense of volume, which was difficult to express with previous open-ear models. The "Dual Bass Enhancement Technology," which combines a low-frequency reinforcement algorithm using digital processing and a dynamic EQ algorithm that maintains the volume of low frequencies even at low volumes, has improved the sound expression. ■ Up to 13 hours of continuous playback Equipped with a long battery that allows for up to 13 hours of continuous playback with the earphones alone, which is the longest class for open-ear models. By using the charging case in combination, up to 34 hours of continuous playback is possible. ■ You can hear the surrounding sounds while "while-listening" You can hear the surrounding sounds even in offices and cafes outside, so you can use them safely. ■ Your voice is not muffled and you can speak naturally Beamforming technology is used to ensure that your voice is clear even in noisy environments. ■ Lightweight and comfortable to wear, ear-hook style The earphones are lightweight, weighing approximately 10.5g. The ear-hook style, made of soft material, fits everyone perfectly. ■ Supports multi-point, which can connect to two Bluetooth devices simultaneously ■ Splash-proof specifications that protect the earphones from rain and water splashes ■ Easy and simple operation ■ Cable with overheating prevention function for safety Thank you for viewing.
