Audio manufacturer TOZO revealed its new Golden X2 Pro wireless earbuds at CES today, featuring dual digital-to-analog converters (DACs) and expanded smart features. These new earbuds are TOZO's push into the premium audio segment. The X2 Pro uses a hybrid driver system, pairing a 12 mm dynamic driver with a Knowles balanced armature. New earbuds support LDAC codec and Hi-Res Wireless Audio certification, with a frequency response ranging from 12 Hz to 44.1 kHz. The active noise cancellation system employs six microphones to reduce environmental noise by up to 50 decibels, while automatically adjusting to surrounding conditions. For spatial audio, the earbuds incorporate gyroscopic sensors to enable head tracking.

A notable hardware addition is the 1.47-inch color display built into the charging case, which shows battery status and allows users to adjust settings without using their phone. The earbuds also include a feature called Vocal Vibration Detection that automatically adjusts audio when the user starts speaking. On the software side, TOZO has added several AI-powered features through its companion app, including language translation, voice transcription, and meeting note generation. The implementation of these features and their effectiveness in real-world use remains to be tested.
