SNACK: 3-line summary
- OnePlus has revealed the OnePlus Buds Pro 4’s features on its global product page, including dual drivers co-engineered with Dynaudio.
- With AAC audio and case recharges, claimed playback reaches 53 hours with noise cancellation off or 26 hours with it on.
- AI Live Translation requires a supported OnePlus device and cloud processing, with a limit of 5,000 minutes a month.
OnePlus has detailed the OnePlus Buds Pro 4 on its official global product page. The advertised 53-hour battery life counts recharges from the charging case with active noise cancellation (ANC) switched off and the AAC audio codec in use—not one uninterrupted charge of the earbuds.

Red I’d like to try a rhythm game with a compatible OnePlus phone and Low game latency switched on. I’m curious how the beat and my taps would line up.
Nea I’d start with a favorite game soundtrack on that Dynaudio-tuned setup. I’d like to follow the quieter instruments behind the main melody.
Six hours in the earbuds with ANC on
Using AAC, OnePlus rates the earbuds alone for up to 13 hours with ANC off or six hours with it on. Including case recharges, those totals reach 53 and 26 hours respectively. These are laboratory figures; actual playback varies with volume, calls, enabled features and other conditions.
The case supports wireless charging on a charging pad, as well as reverse wireless charging from a compatible OnePlus phone.
Two drivers, each with its own DAC
The audio system was co-engineered and tuned with Dynaudio. It pairs an 11mm composite woofer for bass with a 6mm planar tweeter for higher frequencies, using two independent digital-to-analogue converters (DACs) to control the drivers separately.
The hybrid silicone-foam ear tips come in four sizes, giving listeners different fit options.
Translation and low latency depend on the phone
OnePlus lists AI Live Translation for OnePlus devices running ColorOS 17.0 or later. Translation uses cloud processing and is limited to 5,000 minutes per month, with the allowance resetting at the start of the next month. Supported languages are listed in the app.
The quoted gaming latency of as low as 39ms applies only to selected OnePlus phone models with Low game latency enabled—not every Bluetooth connection.
IP55 dust and water resistance applies to the earbuds, not the charging case.
