New wearable products emerge frequently: Xiaomi watch’s gesture interaction function is eye-catching, OPPO earphones have self-developed “Smart Bluetooth”

Many mobile phone brand manufacturers have released new products one after another, including smart watches, TWS headphones, smart bracelets and other new wearable devices. The release of these new products has enriched the product selection in the market. At the same time, with the continuous advancement of technology, various brand manufacturers have created differentiated competition through products with special functions. For example, Xiaomi Smart Watch S4 supports new gesture interaction functions, and OPOO has launched the "Smart Bluetooth" technology to break the industry's longest transmission distance and use it on new TWS headphones.

: Eye-catching gesture interaction function

Looking at smart watches, Xiaomi recently released the Xiaomi Watch S4, equipped with a 1.43-inch AMOLED screen, 326PPI, and the screen brightness has been increased from 120 nits to 1500 nits. In terms of sports and health functions, the upgrade uses a high-precision heart rate blood oxygen sensor and a new self-developed algorithm. The heart rate accuracy is increased to 98.2% compared with the gold standard. In addition, it also supports blood oxygen monitoring, sleep monitoring, etc. Professional running mode has appeared in many Xiaomi watches. Xiaomi Watch S4 also has this function, supporting running posture detection such as vertical amplitude and ground contact time.

In smart watches, the eSIM function has become the key to driving market growth and one of the directions of technological iteration. At present, China Unicom is also promoting the application of eSIM in AI terminals, and the future development trend is worth looking forward to. Xiaomi S4 also has an eSIM version, which means that Xiaomi will not give up the eSIM track and will continue to invest. As a mainstream brand in the field of smart wearable devices, Xiaomi will occupy a larger share in this market.

It is understood that the main control chip of Xiaomi Watch S4 is equipped with UNISOC's W117, which is also the key to S4's support for eSIM function. According to the introduction, W117 supports eSlM independent communication and has the characteristics of high integration, small size and low power consumption.

Xiaomi Watch S4 also supports network Bluetooth dual-mode intercom. In the absence of network, Bluetooth mode intercom is supported, with a maximum range of 200 meters and multiple people can form a team.

It is worth noting that the Xiaomi Watch S4 has a huge upgrade in human-computer interaction. At present, smart wearable device manufacturers are looking for more human-computer interaction methods, including voice interaction, gesture interaction, etc., but it is a pity that the industry has previously promoted the method of air control, but it has not yet made much splash in the field of wearable devices. On the contrary, after Apple launched the finger-controlled watch, many manufacturers followed up with the function of gesture interaction. For example, Meta finally launched a brain-computer wristband device when it released AR smart glasses, which can sense the neural signals of different finger gestures to control AR smart glasses. This time, the Xiaomi Watch S4 has a heavy upgrade of the gesture control function.

Xiaomi introduced that the gesture control function of the Xiaomi Watch S4 is due to the new Xiaomi Pengpai OS 2. The new gesture operation supports snapping fingers to control Mijia devices. The gesture control function not only enhances the functionality and ease of use of the Xiaomi Watch S4, but also wins more attention for it in the fierce market competition. As the technology gradually matures and is accepted by more users, it will become a key selling point for Xiaomi in the field of wearable devices.

In addition, after being equipped with Xiaomi Pengpai OS 2, Xiaomi Watch S4 supports the operation of Mijia devices, Xiaomi cars, mobile phones, tablets, headphones, etc. The addition of more interactive functions and the opening of Xiaomi's smart ecosystem will consolidate and enhance Xiaomi's market position.

OPOO Enco X3: "Smart Bluetooth" breaks the industry's longest transmission distance

OPPO has released a new wireless headset OPOO Enco X3, priced from 899 yuan. This TWS headset, known as the "strongest flagship within a thousand yuan", was also compared with AirPods Pro 2 at the press conference. In the end, it won in terms of sound units, number of DACs, transmission rate, custom EQ and other parameters.

Specifically, OPOO Enco X3 uses a coaxial dual unit, while AirPods Pro 2 is a single unit. OPPO introduced that Enco X3 is equipped with the third-generation ultra-clear coaxial dual unit, with a 50% increase in bass energy and a 160% increase in treble sensitivity, with a frequency response range of 15Hz-40kHz. It is also equipped with dual DAC drivers, which drive the tweeter and woofer respectively. Compared with the single DAC design, the sound design will be more precise.

In terms of technological innovation, since TWS headphones all use Bluetooth technology, but the transmission distance of Bluetooth technology is limited, in order to achieve a longer, more stable and more penetrating Bluetooth connection, OPPO has created "Smart Bluetooth", breaking the industry's longest distance, capable of covering 100 square meters and an ultra-long transmission distance of 400 meters.

In terms of noise reduction, OPOO Enco X3 uses VPU bone voiceprint recognition technology, a new anti-wind noise algorithm, and AI call noise reduction technology, and is equipped with 3 high signal-to-noise ratio microphones. These technologies and components enable Enco X3 to intelligently identify scenes and achieve a maximum noise reduction effect of 50dB.

In other aspects, Enco X3 supports spatial audio, and is not limited to devices or sound sources. In other words, wireless audio can be used by connecting Enco X3 to smartphones of different devices such as Apple, achieving cross-brand compatibility. Users are no longer limited to devices or sound sources of a specific brand, and can freely match devices according to their needs to enjoy the spatial audio experience. This will promote the popularization and application of spatial audio technology, and also expand OPPO's competitive advantage in the TWS field.
