Audio Quality and Sound Performance
The OnePlus Buds 4 deliver impressive sound separation that puts them ahead of many competitors in their class. The dual driver system works hard to keep vocals distinct from instruments. You hear each element of your music with clarity.
The 6mm tweeter handles high frequencies with precision. The 11mm woofer pumps out deep bass without drowning out the rest of the track. This combination creates a balanced sound signature that works well for most music genres.
The dual DAC setup gives each driver independent control. This means the tweeter and woofer operate at their best without interfering with each other. The result is superior audio performance compared to single DAC designs you find in other earbuds.
Active Noise Cancellation performs exceptionally well on the Buds 4. It blocks ambient noise effectively during commutes or office work. Smart Ambient mode lets you hear your surroundings when you need to. You can switch between modes instantly without removing the earbuds.
Call quality stands out as a major strength. The four microphones work together to capture your voice clearly. Background noise gets filtered out, so the person on the other end hears you well. Wind noise reduction helps during outdoor calls.
However, some users report that the shallow ear tip fit affects their listening experience. If the buds don’t sit deep enough in your ear canal, you miss out on bass response and ANC effectiveness. Finding the right ear tip size matters more than usual with this model.
The ceramic metal diaphragm in the 30 layer construction adds durability to the drivers. This design choice helps the sound remain consistent over time. You won’t notice degradation in audio quality after months of use.
Overall, the audio performance justifies choosing these earbuds. The sound quality rivals much pricier options. Whether you stream podcasts, music, or take calls, the Buds 4 handle everything competently. The ANC strength and call clarity make them particularly useful for busy professionals.

Active Noise Cancellation and Ambient Features
The OnePlus Buds 4 feature a dedicated Active Noise Cancellation system that works hard to silence distractions. The ANC performance ranks among the best in its class, effectively blocking low frequency rumble from traffic and background chatter.
Smart Ambient mode gives you a clever alternative. You can switch between full ANC and ambient listening without removing the buds. This feature lets outside sounds pass through when you need to hear announcements or conversations.
The four microphones built into these earbuds serve dual purposes. They capture your voice clearly during calls while also feeding audio data to the ANC algorithm. This dual mic approach means noise cancellation improves as you speak, adapting in real time.
Ambient mode shines during specific moments. You might be waiting for a delivery and need to hear a knock on the door. Or you’re commuting and want to stay aware of your surroundings. The Buds 4 handle both situations smoothly. The ambient passthrough sounds natural, not tinny or processed.
The Smart Ambient feature learns your preferences over time. It can automatically switch modes based on your activity or location. This intelligence reduces the number of manual adjustments you need to make throughout the day.
One thing stands out: the ANC doesn’t drain battery as aggressively as some rivals. You get solid noise blocking without sacrificing your listening time. The wireless charging case keeps everything topped up, so you stay mobile longer.
The transparency mode works exceptionally well when you’re in public spaces. Voices come through clearly, and you maintain awareness without removing the buds. This matters if you’re navigating busy streets or waiting in line.
Some users notice that ANC effectiveness depends on ear tip fit. Since the shallow fit affects some people, finding the right size becomes important. Once you find your fit, the ANC and ambient features work as intended. The combination of both technologies makes these earbuds versatile for different situations throughout your day.
Design, Fit, and Comfort
The OnePlus Buds 4 feature an ergonomic design that prioritizes comfort during extended wear. The earbuds sit snugly in your ears thanks to their thoughtful shape and contoured form. The lightweight construction means you won’t feel fatigued after hours of listening.
OnePlus included multiple ear tip sizes to match different ear canal dimensions. This customization helps you find the perfect fit for your unique ears. The silicone tips grip gently without causing pressure points or soreness.
However, some users report fit inconsistencies that affect their experience. The stalk design occasionally pushes against the earlobe, creating minor discomfort during extended sessions. A shallow ear tip fit bothers certain listeners who prefer a deeper insertion. These issues don’t impact everyone equally, so your personal experience may differ.
The earbuds weigh just enough to feel secure without slipping out during movement. Whether you’re commuting, exercising, or working at your desk, they stay put. The secure fit gives you confidence during phone calls and video meetings.
The IP55 water and dust resistance means you can wear them in various conditions without worry. Sweat from workouts won’t damage the internal components. Light rain or humid environments pose no problem for these earbuds.
The charging case design complements the earbuds’ overall aesthetic. It fits easily into pockets and bags without taking up much space. The case feels solid and protects your earbuds when you’re not wearing them.
Comfort during long listening sessions depends partly on ear tip selection. Spend time testing different sizes to discover which feels best for your ears. Once you find the right fit, the OnePlus Buds 4 deliver consistent comfort throughout your day.
The stalk design, while sometimes problematic for certain ear shapes, provides an easy grip for insertion and removal. This practical feature makes handling the earbuds simple and intuitive. Overall, the design balances form and function to create a wearable that works for most users.

The charging case extends your total usage window significantly, giving you multiple days of listening before you need to plug in.
What makes the battery standout is how efficiently the Buds 4 manage power consumption. The Active Noise Cancellation system doesn’t drain your battery as aggressively as competing models. You can keep ANC enabled throughout the day and still have juice left when you need it most.
Wireless charging adds real convenience to your routine. The case supports wireless charging, so you can simply place it on any compatible pad without fumbling with cables. Traditional wired charging is also available if you prefer it. This flexibility means you can charge wherever works best for your lifestyle.
The battery management system works intelligently behind the scenes. The dual DAC setup and individual driver control don’t compromise your battery performance. OnePlus engineers optimized power delivery to each component so nothing wastes energy unnecessarily.

Battery longevity remains solid over extended ownership. The lithium ion cells inside hold their capacity well after months of regular use. This means your Buds 4 won’t show significant degradation in battery performance after a year of daily charging cycles.
The IP55 water resistance doesn’t interfere with battery efficiency either. The protective sealing keeps moisture out while allowing proper power management. You can confidently use these earbuds in various conditions without worrying about battery complications from environmental exposure.
Call Quality and Microphone Performance
When you take a call on the OnePlus Buds 4, the experience feels clear and natural. The four microphones work together to capture your voice accurately while filtering out background noise. This setup gives you confidence that the person on the other end hears you properly.
Wind noise handling stands out as a real strength. You can take calls outdoors without worrying that gusts will disrupt the conversation. The microphone array processes sound intelligently, so only your voice comes through clearly. This matters when you’re commuting or walking between meetings.
The call clarity improves further when you pair the microphones with the Active Noise Cancellation system. ANC doesn’t just block incoming sounds—it also helps isolate your voice during calls. The other person experiences less interference from your surroundings, which makes conversations feel more intimate and focused.
Smart Ambient mode adds another layer of usefulness during calls. When you enable it, you can hear your environment while staying on the line. This proves helpful if you need to stay aware of traffic, announcements, or someone approaching you. The transition between modes happens smoothly without audio dropouts.
Real world testing shows the microphones maintain consistent performance throughout various conditions. Whether you’re in a quiet office or a busy café, the Buds 4 adapt well. The voice detection algorithm learns when you’re speaking versus when you’re listening, which reduces unnecessary processing.
One thing to note: some users mention that the stalk design occasionally affects microphone positioning. If the earbud sits shallowly in your ear, call quality can dip slightly. Finding the right ear tip size helps resolve this issue for most people.
The Bluetooth connection remains rock solid during calls. Dropouts are rare, and the codec handling ensures audio stays synchronized. This reliability means you won’t experience those awkward moments where the call cuts out mid sentence.
Overall, the OnePlus Buds 4 deliver call performance that matches or exceeds competitors in the same category. The four microphone system proves its worth in real conversations, making these earbuds dependable for both professional and personal calls.
