The OnePlus Buds 4 ANC Storm Gray TWS Bluetooth Earbuds are built for people who want premium wireless sound with modern noise control. Designed as true wireless earbuds, they deliver an immersive listening experience for music, podcasts, and calls—whether you’re commuting, working out, or traveling. The Storm Gray finish gives them a sleek, contemporary look, while the ergonomic in-ear design helps keep the fit secure for extended sessions.
These earbuds feature advanced Active Noise Cancellation (ANC) with real-time adaptive control. ANC helps reduce unwanted ambient noise so you can focus on what you’re listening to, even in busy environments. The system also supports multiple noise control modes, including ANC on, adaptive mode, transparency mode, and ANC off—so you can switch based on your surroundings. For example, ANC on is ideal for trains and crowded streets, while transparency mode is useful when you need to stay aware of announcements or traffic.
Sound quality is a key strength of the Buds 4 ANC. With a 11mm woofer and 6mm tweeter driver unit, the earbuds are tuned to provide balanced audio with clear treble, deep bass, and well-defined mids. The frequency response is specified at 15Hz–40KHz, supporting rich low-end presence and detailed high-frequency clarity. For audio enthusiasts, the combination of LHDC 5.0 / AAC / SBC Bluetooth codecs helps deliver a more refined listening experience depending on your device and app support.
Built for everyday reliability, the earbuds offer long playback time with the charging case. The source data specifies up to 11 hours playback on the earbuds (ANC Off, 50% volume, AAC) and up to 45 hours with the case. When ANC is on (50% volume, AAC), playback is also supported for extended listening. Charging is quick as well: about 50 minutes for the earbuds and about 80 minutes for earbuds with the case. This makes the Buds 4 ANC practical for quick top-ups before heading out.
For active users, the Buds 4 ANC includes IP55 dust and water resistance, making them suitable for workouts and outdoor activities. This rating supports confidence during sweat-heavy sessions and light exposure to moisture. The ergonomic design is intended to stay comfortable during long wear, helping reduce the need for frequent readjustment—an important factor when you’re using earbuds for calls, study, or long commutes.
Connectivity is handled via Bluetooth 5.4 with a working range of up to 10 meters, supporting stable wireless performance around your home or office. The earbuds also support features aimed at smoother media use, including 47ms low latency for more responsive audio—helpful for watching videos and enjoying gaming-style content. For pairing convenience, Google Fast Pair is supported with dual-device connection, making it easier to switch between compatible devices.
For voice calls and voice assistant use, the earbuds include a microphone system with 6 microphones total (3 mics per side). The product data also mentions AI call noise cancellation, which helps reduce background noise during calls. This makes the Buds 4 ANC a strong choice for hands-free communication while walking, commuting, or working in moderately noisy environments.
The package includes OnePlus Buds 4 (1 pair), OnePlus Buds 4 Charging Case (1), a Type-C charging cable (1), ear tips in S/M/L pairs with M pre-installed, and a user manual & safety and warranty document (1). With multiple ear tip sizes, you can choose the fit that best matches your ear shape for improved comfort and sound isolation.
The earbuds come with a 1 Year warranty. Warranty claims must be made with the original box and all accessories, helping ensure smoother after-sales support if you ever need service.
