The Sennheiser CX True Wireless in white are in-ear headphones designed for those who want a reliable wireless listening experience. They feature 7 mm TrueResponse transducers that deliver a wide frequency range from 5 Hz to 21,000 Hz, ensuring a balanced sound that you can further refine using the built-in equalizer or the Bass Boost setting. Connectivity is handled via Bluetooth 5.2, supporting codecs like SBC, AAC, and aptX for a stable connection within a 10-meter range. These white earbuds are built for daily use with an IPX4 rating, meaning they can handle splashes of water or sweat during a workout. The lightweight design, weighing only 37 g, is complemented by four sizes of silicone ear adapters to help you find a secure and comfortable fit. You can manage your music and calls through customizable touch controls directly on the buds. Power is provided by lithium-ion batteries that offer up to 27 hours of total playtime when using the USB Type-C charging case. A full charge takes about 1.5 hours, but if you are in a hurry, a quick 15-minute charge provides an hour of listening time, making them practical for a busy commute or a sudden trip to the gym.
