OnePlus has quietly added the Buds Pro 4 to its global website, giving a full look at its next flagship earbuds before any launch event. The page lists a Dynaudio-tuned dual-driver setup, adaptive noise cancellation and a battery rating of up to 53 hours with the case.
There is no price, release date or list of markets yet, so it is unclear which regions will get them.
Two drivers, two DACs
OnePlus’s product page describes two drivers per earbud, a composite woofer of 11mm and a planar tweeter of 6mm, each with a DAC of its own. The company claims 50% more bass driving force than the previous generation. Hi-Res Audio over LHDC 5.0 is supported, along with spatial audio and personalised tuning.
OnePlus says the adaptive noise cancellation removes twice as much noise as the Buds Pro 3. Calls are handled by three microphones and a bone-conduction sensor, according to the listing as reported.
Battery and durability
The 53-hour figure is with the charging case and noise cancellation off; OnePlus’s own footnotes tie such numbers to lab conditions. A Gizmochina write-up of the listing puts it at 26 hours with ANC on over AAC, and 13 hours from the earbuds alone without ANC. It adds that ten minutes on the charger buys 14 hours, and that the case charges wirelessly.
The earbuds are rated IP55 for dust and water. OnePlus states that the charging case is not water-resistant.
Software features
The listing mentions AI live translation, an AI call-clearing mode, Dolby-powered recording, Gemini voice access and dual-device connection. Colours shown are Titanium Shadow and Polar White.
Gizmochina notes the overlap with the Oppo Enco X4, which sells for 219 euros in Europe, and suggests the Buds Pro 4 could be a related product. OnePlus has not said so, and has set no price.
