OnePlus has officially released the smaller 43mm OnePlus Watch 3 in the United States, alongside the OnePlus Buds 4. If you want to grab either of them, there’s a launch discount until the end of July.
The OnePlus Watch 3 (43mm) is OnePlus’s first full-featured smartwatch in a smaller 43mm size, making it a better fit for more wrist sizes. Thanks to its Dual-Engine Architecture, it can last up to 60 hours in Smart Mode and up to 7 days in Power Saver Mode. This should solve the common battery life issues of smaller smartwatches and make this watch better than the last Watch 3.
The OnePlus Watch 3 (43mm) is the smallest model in the OnePlus Watch lineup, made for a lighter and more comfortable fit. Without the strap, it weighs just 37.8 grams, ensuring it feels great even after long wear. It has a high-quality stainless steel case with 2.5D curved glass, making it both durable and stylish, along with 12 printed hour markers for a classic watch look.
OnePlus claims to have improved the motherboard efficiency by 10% after making it 0.5mm thinner than the 46mm model. Owners can customize the watch with many different watch faces, from sporty designs to classic styles, and even use personal photos or videos for custom faces.
The OnePlus Buds 4, on the other hand, provides top-tier audio with smart noise cancellation, a coaxial dual-driver system, and dual DACs. This setup includes an 11mm 30-layer ceramic metal woofer for deep bass and a 6mm flat diaphragm tweeter for crisp highs, covering a wide frequency range from 15Hz to 40KHz.
The coaxial design keeps sound balanced and accurate. The dual DAC setup prevents signal interference, with each DAC handling highs and lows separately for cleaner audio. With Hi-Res Audio Wireless certification and LHDC 5.0, the Buds 4 support ultra-high-quality sound up to 192kHz, 24-bit depth, and 1Mbps transmission, preserving every detail of the original recording. The Golden Sound feature customizes audio based on your ear shape and hearing, while OnePlus 3D Audio uses special algorithms to create immersive surround sound with depth and direction.
