OnePlus Buds 4 Storm Gray with ANC
Score: 87/100Rankings
Technics EAH-AZ100 are reference-class true-wireless earbuds with 10 mm magnetic fluid drivers, adaptive hybrid ANC, and Dolby Atmos with head tracking. Their battery life and codec support are strong, but bass bleed and limited water resistance are trade-offs. Ideal for audiophiles and travelers who value high-resolution sound and multipoint connectivity.
OnePlus Buds 4 are mid-range true-wireless earbuds with a coaxial dual-driver system, hybrid ANC up to 55 dB, and LHDC 5.0 high-resolution audio support. They lack wireless charging and have a bulkier case, and Bluetooth range is limited to about 10 m. They fit users looking for strong ANC, long battery life, and hi-res audio on a budget.
