Hi-Res certification, adaptive noise cancellation, low-latency gaming mode, and good battery life with the case.
In-ear TWS headphones of a confident mid-range, released at the very beginning of 2024. The model features a dual-driver system: a 10.4mm woofer and a 6mm tweeter in each earbud. This ensures powerful bass processing with clear mid and high frequencies. The OnePlus Buds 3 support the LHDC 5.0 codec with Hi-Res Audio Wireless and Spatial Audio technology with Dolby Atmos.
The active noise cancellation system on board the headphones suppresses sounds up to 49 dB in volume. Additionally, the model employs ENC noise reduction to mute surrounding noises during conversations. For pairing the headphones with one or two audio sources, wireless communication via Bluetooth v5.3 is used. The model supports the Google Fast Pair quick connection feature.
In gaming mode, low latency achieves an input lag of about 94 ms. The battery life of the TWS headphones without noise cancellation is up to 10 hours, and with noise cancellation on, around 6.5 hours. The charging case extends the battery life up to 44 and 28 hours, respectively. Additionally, the headphones are equipped with a dust and water-resistant design (IP55).

Popular questions
How well do they block out external sounds outdoors and on public transport?
Adaptive ANC handles monotonous low-frequency hum fairly well, so you’ll be comfortable on a plane or bus. However, the headphones perform only moderately with sudden sounds and loud voices, letting some noise through. For safety outdoors, there is a transparency mode—it conveys the surroundings very naturally.Source:SpecificationsExpert reviews
How many hours does the battery last with noise cancellation turned on?
The charge will last for approximately 6.5 hours of continuous music playback, and you can get up to 10 hours with ANC turned off. If the headphones run out of battery, 10 minutes in the case will provide approximately 7 more hours of use. The case itself does not support wireless charging and can only be charged via the included USB-C cable.Source:SpecificationsExpert reviews
Will they withstand a workout or a run in the rain?
Yes, they have IP55-rated dust and water resistance. They can easily handle heavy sweating at the gym or rain outdoors, but they must not be fully submerged in water or washed under a running tap. The charging case has no protection, so the earbuds must be dry before being placed inside.Source:SpecificationsExpert reviews
How is the sound on the OnePlus Buds 3—would they suit audiophiles?
This model is designed for bass enthusiasts, not those who appreciate neutral sound. The low frequencies are heavily emphasized, which is great for electronic music or hip-hop, but as a result, vocals and high notes sound muffled. If you need a more balanced sound, you’ll have to adjust the equalizer extensively in the app.Source:Expert reviews
Is it necessary to have a OnePlus smartphone to set up the headphones?
No, the official HeyMelody app provides full access to all features on both Android and iOS. It lets you switch noise-cancellation modes, change the controls, and customize the sound to your liking. OnePlus phone owners don’t need to download anything—the entire menu is already built into the system.Source:SpecificationsExpert reviews
Is it convenient to control music and volume without a phone?
The volume can be adjusted with a simple swipe up or down along the earbud stem—an uncommon feature in this category that is especially useful when traveling. The other touch controls can also be easily reassigned to suit your preferences. The main practical drawback is that, due to the case’s smooth plastic, the earbuds can be quite difficult to remove from the charging case.Source:SpecificationsExpert reviews
