OnePlus Nord Buds 4 Pro True Wireless Earbuds
The OnePlus Nord Buds 4 Pro is a high-performance audio solution designed for deep immersion and smart connectivity. Featuring flagship-grade 55dB Active Noise Cancellation certified by TÜV Rheinland and the latest Bluetooth 6.0 technology, these earbuds deliver high-resolution sound, adaptive real-time noise control, and AI-driven features. With 54 hours of total playtime and fast charging that gives 13 hours from just 10 minutes, they're engineered for marathon listening sessions.
Key Features
A dual-feed ANC system certified by TÜV Rheinland suppresses a wide range of frequencies up to 5000 Hz, ensuring focus in even complex, noisy environments like transit and open offices.
Using AI, the earbuds dynamically generate noise reduction curves every second based on your ear canal shape, wearing status, and ambient noise for personalized, responsive comfort.
Built with N52H magnets and PET titanium-coated diaphragms, these drivers provide powerful bass extension, sharp transient response, and minimal distortion even at volume.
Supports high-fidelity 96kHz/24-bit audio via wireless bitrates up to 1 Mbps, delivering near-lossless sound quality even in areas with high signal interference.
Individual 62 mAh earbuds provide up to 13 hours on a single charge (ANC off), while the 530 mAh case extends total runtime to a massive 54 hours.
Just 10 minutes of charging yields 13 hours of playback when used with the case. Full earbuds recharge in ~60 minutes, and a complete case in ~90 minutes via USB-C.
The latest Bluetooth 6.0 provides an ultra-stable connection up to 10 meters, with seamless dual-device support—play media on a tablet, then instantly switch to answer calls on your phone.
Six microphones with AI noise cancellation deliver crystal-clear voice clarity. 3D Spatial Audio and dedicated Game Sound Spatial Audio modes pull you into immersive soundscapes for entertainment.

Frequently Asked Questions
Where can I buy the original OnePlus Nord Buds 4 Pro in Bangladesh?
You can buy 100% original OnePlus Nord Buds 4 Pro online directly from umrelo.com.bd, or visit our physical retail experience center in Motalib Plaza, Dhaka to check the product in person before purchase.
How powerful is the 55dB ANC really?
55dB ANC, certified by TÜV Rheinland, is flagship-grade noise suppression. It cuts low-frequency rumble from trains and AC units very effectively, and handles office chatter and traffic well. Real-world effectiveness depends on fit, seal, and noise type — some high-pitched sounds may break through more than deep bass.
What is LHDC 5.0 and does my phone support it?
LHDC 5.0 is a high-bandwidth wireless codec that transfers data at up to 1 Mbps, delivering near-lossless audio at 96kHz/24-bit. Most modern Android phones support it, especially OnePlus devices. iPhones do not support LHDC, so iPhone users will hear high-quality AAC instead.
How long does the battery really last with ANC on?
The spec is ~7 hours with ANC on using AAC codec at typical volume. With LHDC 5.0 enabled, it drops to ~6 hours. Actual playtime depends on volume level, audio codec, whether ANC is always maximum or adaptive, and incoming calls.
How does 10-minute charging give 13 hours of playtime?
That's the combined playtime with the case when it's fully charged. So if you top up both earbuds and the case for 10 minutes, you get 13 additional hours of listening before needing to charge again. It's one of the fastest fast-charge features in the earbud market.
How do the Pro and base Nord Buds 4 compare?
The Pro model wins on ANC depth (55dB vs 52dB), Hi-Res LHDC 5.0 audio (base model doesn't have it), and slightly faster fast charging (13 vs 11 hours). The base Nord Buds 4 have Bluetooth 6.1 (newer than Pro's 6.0) and cost less. If you prioritize ANC and Hi-Res sound, the Pro is worth it; for budget value, the base model is solid.
