boAt Nirvana Ivy Pro VS OnePlus Buds 4

Both the boAt Nirvana Ivy Pro and the OnePlus Buds 4 share the same fundamental design DNA: true wireless, in-ear form factors with stereo playback and no neckband or wingtips. For the vast majority of users, day-to-day handling and wearing experience will feel comparable on paper.

Where they meaningfully diverge is in ingress protection. The Nirvana Ivy Pro carries an IPX4 rating, which covers sweat and light splash resistance — adequate for workouts and casual outdoor use, but it offers no rated dust protection. The OnePlus Buds 4 steps up to a full IP55 certification, meaning it is rated against dust ingress and can withstand sustained low-pressure water jets from any direction. In practical terms, the Buds 4 can handle rain, poolside splashes, and dusty environments that the Ivy Pro is not formally rated for.

For design, the OnePlus Buds 4 holds a clear edge due to its superior IP55 protection. If you use earbuds strictly at the gym or in light-rain conditions, the IPX4 on the Ivy Pro may suffice — but for anyone who exercises outdoors regularly or lives in dusty or wetter climates, the Buds 4's more robust rating offers meaningfully better real-world durability.

On the noise isolation front, both earbuds are evenly matched — each offers active noise cancellation (ANC) alongside passive noise reduction through their in-ear fit. The driver size is also identical at 11 mm on both, so neither has a raw hardware advantage in transducer size.

The frequency response is where the two diverge significantly. The Nirvana Ivy Pro covers the standard audible range of 20 Hz–20,000 Hz, which is technically sufficient for human hearing. The OnePlus Buds 4, however, extends to 15 Hz–40,000 Hz — reaching deeper into sub-bass territory and well into the ultrasonic range. While frequencies above 20 kHz are inaudible to most people, the wider low-end extension to 15 Hz can translate to a more physical, felt sense of deep bass. On the imaging side, the Buds 4 also adds spatial audio support, enabling a more three-dimensional soundstage — a meaningful perk for movie-watching and immersive music listening. The Ivy Pro counters with Dolby Atmos, which provides its own form of surround-sound processing, though notably without the broader spatial audio framework the Buds 4 offers.

The OnePlus Buds 4 holds the edge in sound quality on spec data alone. Its wider frequency range and spatial audio support give it greater versatility across music, gaming, and media consumption, while the Ivy Pro's Dolby Atmos certification offers some compensation but does not close the gap entirely.

The battery story here involves a genuine trade-off rather than a clean winner. The OnePlus Buds 4 lasts 11 hours on a single charge versus the Nirvana Ivy Pro's 8 hours — a 37.5% advantage that is highly meaningful for long-haul travelers, commuters, or anyone who regularly goes a full day without access to the case. Three extra hours per session is the difference between comfortably finishing a transatlantic flight and scrambling to charge mid-trip.

Flip the lens to total system endurance, though, and the picture shifts. The Ivy Pro's case delivers 42 hours of additional charge, bringing its combined total to roughly 50 hours. The Buds 4 case provides 34 hours, for a combined total of around 45 hours. So users who top up their earbuds regularly throughout the day — keeping them in the case between sessions — will actually get more cumulative listening time from the Ivy Pro before needing a wall outlet. Charge times are close, with the Buds 4 edging slightly faster at approximately 80 minutes versus 90 minutes for the Ivy Pro, though neither supports wireless charging.

Declaring a winner depends on usage pattern. For marathon single-session listening, the OnePlus Buds 4 holds the clear advantage. For users who prioritize going longer between case recharges — road trips, camping, or multi-day travel — the Ivy Pro's higher total system capacity makes it the more practical pick.

Much of the connectivity foundation is shared: both earbuds run over the same 10 m Bluetooth range, support fast pairing and AAC, charge via USB-C, and clock in at nearly identical audio latency — 50 ms for the Ivy Pro versus 47 ms for the Buds 4. That 3 ms gap is imperceptible in practice, so neither holds a real-world edge in lip-sync or gaming responsiveness.

The meaningful split is in high-resolution codec support. The Nirvana Ivy Pro carries LDAC, Sony's widely adopted hi-res wireless codec capable of transmitting up to 990 kbps — and critically, it is natively supported by the vast majority of Android devices. The OnePlus Buds 4 opts for LDHC (also known as HWA), a competing hi-res codec with comparable bitrate potential but a significantly narrower device ecosystem, with strongest support on Huawei and select other hardware. For most Android users outside that ecosystem, LDHC may simply go unused, reducing the Buds 4 to AAC in practice. The Buds 4 does run the marginally newer Bluetooth 5.4 versus the Ivy Pro's 5.3, though the practical difference between these two versions is minimal for consumers.

On connectivity, the Nirvana Ivy Pro has the broader real-world advantage for most users, purely because LDAC's ecosystem reach far exceeds LDHC's — making high-resolution wireless audio a realistic, not theoretical, benefit for the majority of Android listeners.

Across the features category, these two earbuds are remarkably well-matched. Both support ambient sound mode, in-ear detection, fast charging, 2-device multipoint connectivity, mute, voice prompts, on-device controls, and even include a travel bag. For the overwhelming majority of daily-use scenarios, owners of either pair will have access to the same core feature set.

The only spec that separates them is the find device feature on the OnePlus Buds 4, which the Nirvana Ivy Pro lacks. In practice, this allows users to trigger an audible alert from the earbuds or case when misplaced — a small but genuinely useful convenience for anyone prone to losing their gear around the house or in a bag.

Given how closely aligned everything else is, the OnePlus Buds 4 holds a narrow edge in this category solely due to its find device functionality. It is not a decisive advantage, but it is a real one — and in an otherwise tied feature set, it tips the scales.

The microphone category is a straight tie. Both the boAt Nirvana Ivy Pro and the OnePlus Buds 4 deploy 6 microphones and feature noise-canceling mic technology — a configuration typically used to enable beamforming, where multiple mics work in concert to isolate the user's voice while suppressing background noise like wind, traffic, or crowd chatter.

A 6-mic array is a generous count at this tier, and combined with noise-canceling processing, both earbuds are well-equipped for call clarity in demanding environments. Based strictly on the provided specs, there is no differentiator between them — neither holds an advantage here.
