The OnePlus Buds 4 adopts a next-generation spraying process, and the shell is matte, and it is available in two colors: space gray and pine shadow green. Combined with ergonomic design, a single earphone weighs 4.7g, supports IP55 dust and water resistance, and is more assured to use in outdoor sports and other scenarios.
The OnePlus Buds 4 supports a 55dB active noise cancellation depth covering the 5500Hz ultra-wide frequency range. The earbuds will actively calculate noise cancellation in real time according to the ambient noise situation to match a more suitable noise cancellation effect. At the same time, the headphones also effectively improve the noise cancellation effect of human voices, and can also have a quieter noise cancellation experience in places where people are noisy.
The earbuds are equipped with an adaptive mode that automatically adjusts the level of noise cancellation and transparency according to the level of ambient noise, making quiet environments more transparent and reducing ear pressure. In noisy environments, there will be more emphasis on noise reduction to provide an immersive listening experience. The headset supports three-microphone AI call noise reduction, which can more accurately pick up human voices and reduce noise.
In terms of sound quality, the headphones use flagship-level coaxial dual drivers (11mm+6mm dual dynamic coils), and the high and low woofers are driven separately through dual DACs to present clearer sound details. The earbuds support BassWave 2.0 dynamic bass and golden listening functions, which can further improve low-frequency performance and reduce hearing loss caused by individual differences. The headphones also support LHDC high-definition audio decoding, full-scene spatial sound, and have passed the Hi-Res gold standard certification.
OnePlus Buds 4 supports three major functions: AI simultaneous interpretation, AI face-to-face translation, and AI call summarization, which need to be used with specific models. Among them, AI simultaneous interpretation supports dozens of foreign languages, which is suitable for scenarios such as foreign language classes and foreign language speeches. AI face-to-face translation is suitable for two-way communication in foreign languages. The AI call summary function can intelligently generate key records based on the content of the call.
OnePlus Buds 4 supports dual device connection, and the phone calls when the tablet is playing games, and the audio can be streamed. The earbuds support Bluetooth 5.4, and can be unlocked with OnePlus mobile phones, and can be connected up to 400 meters of ultra-long distance, with stronger anti-interference capabilities. In addition, the headset also supports a low-latency gaming mode, with headset latency as low as 47ms.
In terms of battery life, the OnePlus Buds 4 can reach 45 hours of battery life with the earphone case and 11 hours of battery life with the earphone body in AAC mode and active noise cancellation mode disabled. With active noise cancellation mode enabled, it can last up to 24 hours with the earphone case and 6 hours with the earphone body.
