OnePlus Buds 4
With the rise of wireless audio devices, the market is flooded with TWS (True Wireless Stereo) options. But before investing in a pair, it’s crucial to understand what you’re paying for—and whether it’s really worth it. How to choose the right TWS earbuds and gives us a hands-on review of the OnePlus Buds 4.
🔍 TWS Buying Guide: What You Need to Know Before Buying
1. Drivers Matter – But Not the Way You Think
Most brands brag about 13.4mm or 12.4mm drivers—but size doesn’t always mean quality. It’s more about how well the drivers are tuned. Dual-driver setups, as seen in OnePlus Buds 4 (11mm + 6mm), offer better frequency separation, resulting in clear vocals, crisp treble, and strong bass.
Pro Tip: Don’t fall for marketing; check reviews for sound signature and tuning.
2. Audio Codecs – The Secret to Good Sound
SBC and AAC are common, but LHDC or LDAC codecs offer high-resolution sound—ideal for audiophiles.
OnePlus Buds 4 supports LHDC 5.0, giving it a significant edge in sound quality if your phone supports it.
Warning: Many budget TWS offer only SBC/AAC, leading to lower sound fidelity.
3. Active Noise Cancellation (ANC) – Necessary or Gimmick?
ANC is everywhere now—even in budget buds. But the quality of ANC varies massively.
The OnePlus Buds 4 features up to 45dB ANC with adaptive modes, which automatically adjusts noise cancellation based on your environment.
Real-world test: Works well on airplanes, traffic, or noisy cafes.
4. Mic Quality – Not Just for Calls
TWS mics are crucial for calls, video conferencing, and even voice notes.
OnePlus Buds 4 comes with a triple mic setup and AI noise reduction, and the call quality is noticeably clearer than its competitors in noisy environments.

Comfort directly impacts how long you can wear your earbuds.
OnePlus Buds 4 has a dual-tone stem design and pressure-relief vents, making it lightweight (around 4.7g) and perfect for long wear.
