LeEco Le S3 Audio and Connectivity

Audio and Connectivity

One of the notable omissions in the Le S3 is the 3.5mm headphone jack, following a trend that was just beginning to take shape around its launch time. Users instead rely on USB Type-C connectivity for audio, which might require adaptations for conventional headphone users. However, the device includes a rear-mounted fingerprint sensor, offering added security and convenience, along with other standard sensors like an accelerometer, proximity sensor, and compass.

The phone supports a comprehensive range of network technologies, including numerous GSM, HSPA, and LTE bands, ensuring broad compatibility. For wireless connectivity, it offers dual-band Wi-Fi with support for a/b/g/n/ac protocols, Bluetooth 4.1, and an infrared port—a feature often overlooked but useful for controlling other appliances.
