Anker Soundcore C40i Wireless Earbuds, Gold

The Anker Soundcore C40i are wireless earbuds built with an open-ear design, which allows the user to maintain awareness of their surroundings. Audio is produced by 11 mm dynamic drivers with neodymium magnets, operating within a 20 Hz to 20,000 Hz frequency range. The earbuds establish a wireless connection to source devices using Bluetooth 5.4 and support both AAC and SBC audio codecs for standard playback quality on iOS and Android devices. The earpieces are constructed from thermoplastic polyurethane.

For communications, the C40i is equipped with a dual-microphone array that incorporates noise-canceling technology to enhance vocal clarity during calls. The total continuous playback time is 21 hours when used with the included charging case. The system supports fast charging, with a 10-minute charge providing additional use, and the case recharges fully in 1.5 hours via a USB-C port. On-device physical buttons allow for direct control over volume, track selection, and call management. An IPX4 rating indicates resistance to water splashes and sweat from any direction.
