{"product_id":"oneplus-buds-4-wireless-earbuds","title":"OnePlus Buds 4 True Wireless Noise Cancelling Earbuds (International Version)","description":"\u003cp\u003eOnePlus Buds 4 use a two-driver layout — an 11 mm woofer alongside a 6 mm tweeter — with each driver fed by its own tailored DAC, which is not common at this level. Adaptive cancellation is rated up to 55 dB across a bandwidth reaching 5,500 Hz, a figure that reads higher than several considerably pricier models. They suit Android listeners who want dual drivers, a \u003cimg\u003ehigh-resolution codec and long runtime in one pair.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\u003ch3\u003eDual drivers, twin DACs\u003c\/h3\u003e\n\u003cp\u003eThe 11 mm unit handles low frequencies while a 6 mm tweeter takes the highs, and each is driven by its own separately tuned DAC rather than sharing one signal path. Frequency response runs from 15 Hz to 40 kHz, and there are three microphones per side. Splitting the work this way reduces interference between the bands, which shows up as clearer separation between vocals and instruments.\u003c\/p\u003e\n\u003ch3\u003eAdaptive ANC up to 55 dB\u003c\/h3\u003e\n\u003cp\u003eCancellation is real-time adaptive, recalculating 800 times per second, and reaches up to 55 dB across a bandwidth of up to 5,500 Hz. Four modes are available: ANC on, Adaptive, Transparency and off. Calls run through a three-microphone AI noise cancellation system that OnePlus rates as a 200% improvement in voice cancelling over the previous model. In practice, steady low-frequency noise such as aircraft or air conditioning is what disappears most convincingly.\u003c\/p\u003e\n\u003ch3\u003eBattery and fast charging\u003c\/h3\u003e\n\u003cp\u003eOn AAC with ANC off, the buds run 11 hours and 45 hours with the case; with ANC on that becomes 6 hours and 24 hours. Switching to LHDC shortens it: 9 hours and 37 hours with ANC off, 5.5 hours and 22 hours with ANC on. Talk time is 6 hours with ANC off and 4 hours with it on. A 10-minute charge gives 3.5 hours of playback, or 11 hours counting the case; a full charge takes about 50 minutes for the buds and about 80 minutes with the case.\u003c\/p\u003e\n\u003ch3\u003eConnection, protection and features\u003c\/h3\u003e\n\u003cp\u003eBluetooth 5.4 with Steady Connect gives an effective range of 10 m, and codecs cover LHDC 5.0, AAC and SBC, with LHDC 5.0 reaching 1 Mbps at 24-bit\/192 kHz. Dual-device connection and Google Fast Pair are supported, and gaming latency is rated at 47 ms. The earbuds carry an IP55 dust and water rating (the case is not included in that rating). Other features include OnePlus 3D Audio, a six-band Sound Master EQ, Golden Sound hearing personalisation, AI Translation, Find My Earbuds and swipe volume control.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%;
