OPPO has opened pre-orders for the Watch S2 and Enco X4 earbuds. The company has not yet released detailed specifications for these new devices, but they are expected to launch alongside the Find X10 series smartphones.
For comparison, the previous Watch S model was released on October 16, 2025, starting at ¥1,299. That device featured an 8.9mm thickness, weighed 35g, and had a steel case with a screen brightness of 3,000 nits. It also included 16-channel blood oxygen monitoring, 8-channel heart rate tracking, ECG electrodes, and wrist temperature measurement.
The predecessor Enco X3 earbuds were launched in October 2024, with the wired charging version priced at ¥899 and the wireless version at ¥949. The X3 model supported dynamic noise cancellation, a maximum active noise cancellation of 50dB, and 5,500Hz ultra-wideband noise reduction. It also featured AI voice noise cancellation and a combination of 3 microphones and a bone conduction VPU.
According to leaks from blogger @Digital Chat Station, the Enco X4 will feature an in-ear design with more refined craftsmanship than its predecessor. The new earbuds are expected to offer improved sound quality and noise cancellation, as well as AI real-time translation similar to Apple's technology.
