Wireless Bluetooth IPX4 Waterproof and Bass Reinforcement Up To 34 Hours of White Audio-Technica ATH-AC5TW Open-Ear Earbuds, 5.4, Dustproof,

This product is certified with the Technical Conformity Mark (2.4 GHz band). It uses air conduction for audio transmission, leaving your ears unobstructed, allowing you to hear the sounds around you. Because the earphones aren't placed inside your ears, they're less likely to hurt your ears even after extended use, and there's no need to worry about your ears getting sweaty. Furthermore, your voice won't muffle during phone calls, allowing you to speak naturally as usual. Large oval driver for rich sound reproduction: A large 17 x 12 mm driver is used to make maximum use of the limited acoustic space in the housing. In addition, an acoustic space and acoustic duct are placed behind the driver to control airflow, bringing out ideal driver movement and reproducing rich sound. Dual Bass Enhancement Technology: Dual Bass Enhancement Technology combines a digital processing algorithm to reinforce the low frequencies with a dynamic EQ algorithm that maintains the volume of the bass even at low volumes. Unique sound tuning allows you to enjoy a balanced, full-bodied sound. Long-lasting, all-day playtime with up to 13 hours of continuous playback: With up to 13 hours of continuous playback* on the earphones alone, you can enjoy music, videos, and social media without worrying about running out of battery. With the charging case, you can enjoy up to 34 hours of continuous playback. Multi-point support allows simultaneous connection to two Bluetooth devices: Connect to your smartphone and your PC or tablet at work or school simultaneously, eliminating the need to switch between Bluetooth-connected devices. For example, if you receive a call on your smartphone while enjoying live video on your tablet, you can respond immediately without having to reconnect.
