EarFun Air Pro 4 Review: Premium Earbud Features Worth Trying?

Most budget earbuds make you give something up. You get decent sound but weak noise cancelling, or good battery life but no app support. The EarFun Air Pro 4 tries to give you all of it for under $100.

These earbuds have aptX Lossless, LDAC, Bluetooth 5.4, adaptive ANC, wireless charging, and six microphones. That list looks like it belongs on a $250 product. So do they actually deliver, or is it just a nice spec sheet?

This review covers sound, noise cancelling, battery life, calls, the app, and gaming. It also looks at three strong alternatives. By the end, you will know if the Air Pro 4 is right for you.

In a Nutshell

• Excellent sound for the price: The Air Pro 4 uses custom 10mm composite drivers. The sound is warm, balanced, and detailed. Lab tests from SoundGuys gave it a 4.8 overall MDAQS score, which is very high for any earbud.
• Strong codec support: You get aptX Lossless, aptX Adaptive, LDAC, AAC, and SBC. Android users with Snapdragon Sound phones can stream high resolution audio up to 24 bit/96kHz.
• Good adaptive noise cancelling: QuietSmart 3.0 ANC claims up to 50dB of noise reduction. In real tests, it cut outside noise by about 75% on the strongest setting. That is very good for a budget pair.
• Long battery life: EarFun rates the buds at 11 hours with ANC off and 7.5 hours with ANC on, plus up to 52 hours in total with the case. The case also supports wireless charging.
• Loaded with features: You get multipoint, Google Fast Pair, in ear detection, a 50ms game mode, LE Audio, and a 10 band EQ with 30 presets. Very few rivals at this price match this list.
• A few weak spots: Call quality in loud places is only average. The sound also changes a little when you turn ANC off, so you may need to adjust the EQ.

EarFun Air Pro 4 Overview

Last update on 2026-10-16 / Affiliate links / Images from Amazon Product Advertising API

The EarFun Air Pro 4 replaced the popular Air Pro 3 in 2024. It looks almost the same from the outside, but the inside got big upgrades. EarFun put in a new Qualcomm chip, new drivers, and better noise cancelling.

The heart of the earbuds is the Qualcomm QCC3091 chip. This chip enables Bluetooth 5.4, LE Audio with the LC3 codec, and Auracast support. It also brings Snapdragon Sound certification, which is rare under $100.

The launch price was $89.99. You can often find them on sale for $70 to $80 on Amazon. At that price, the feature list is honestly hard to believe.

Here is a quick look at the main specs:

• Drivers: 10mm composite diaphragm drivers that improve high frequency detail.
• Chip and Bluetooth: Qualcomm QCC3091 with Bluetooth 5.4 and LE Audio support.
• Codecs: aptX Lossless, aptX Adaptive, LDAC, AAC, SBC, and LC3.
• Battery: Up to 11 hours per charge and 52 hours with the case.
• Water resistance: IPX5 rating that handles sweat and rain.

EarFun also includes a 18 month warranty when you buy from their store. That gives you extra peace of mind for a budget product. For most buyers, the Air Pro 4 sits in the sweet spot between price and performance.

Design and Build Quality

The Air Pro 4 uses a stem style design, similar to AirPods Pro. The stems are short and the buds look clean and simple. You can choose between black and white versions.

The plastic feels light but solid. The surface has a matte finish that resists fingerprints well. The buds do not feel cheap in the hand, even though they cost much less than premium models.

The charging case is a pill shaped design. It is small enough to fit in a jeans pocket. The lid opens smoothly and the magnets hold the buds firmly in place.

On the front of the case, you will find an LED indicator that shows the battery level. A small button lets you pair or reset the earbuds. On the bottom, there is a USB C port for wired charging.

The case also supports Qi wireless charging. You just place it on a charging pad, and it powers up. This feature is still missing on many budget earbuds, so it is a nice bonus here.

The earbuds carry an IPX5 rating. This means they handle sweat, rain, and splashes without trouble. You can wear them to the gym or on a rainy jog with confidence.

Keep in mind that IPX5 is not waterproof. You should never swim with them or drop them in water. One long term owner also mentioned that dropping the buds often caused one side to sound quieter. So handle them with reasonable care, and they should last.

Comfort and Fit

Comfort matters a lot for earbuds. If they hurt after an hour, the sound quality does not matter. Thankfully, the Air Pro 4 feels great for long sessions.

The buds are very lightweight. Most people can wear them for hours without ear fatigue. The stem design also spreads the weight evenly, so they do not pull on your ear.

EarFun includes five sizes of silicone ear tips in the box. This is more than most brands offer. The extra sizes help you find a tight seal, which improves both bass and noise cancelling.

A good seal is very important with these earbuds. If the tips are too small, you will lose bass and the ANC will feel weak. Take a few minutes to test each size before you settle on one.

The fit stays secure during walks and light workouts. Some users find that the buds can loosen during intense running. If you run hard, you might want earbuds with ear wings instead.

The touch controls sit on the stems. They respond well, but they can be a little too sensitive. By default, a single tap changes the volume. This means you may change the volume by accident while adjusting the fit.

The good news is that you can fix this in the app. You can turn off single tap actions or assign new functions. After that small change, the controls become easy to use. Overall, comfort is a clear strength of the Air Pro 4.

Key Features That Stand Out

The Air Pro 4 packs many features you would usually find on flagship earbuds. Let us look at the ones that matter most in daily use.

Bluetooth multipoint lets you connect to two devices at once. You can stay connected to your phone and laptop at the same time. When a call comes in, the audio switches to your phone without any manual steps.

Google Fast Pair makes setup quick on Android. You open the case near your phone and a popup appears. One tap and you are connected. iPhone users can still pair the normal way through Bluetooth settings.

In ear detection pauses your music when you remove an earbud. It resumes when you put it back. This sounds small, but it saves battery and feels very convenient. You can turn it off in the app if you do not like it.

The low latency game mode cuts delay down to about 50ms. This helps keep audio in sync with video and games. It works well for casual mobile gaming.

The earbuds also support LE Audio and Auracast. LE Audio uses the LC3 codec, which delivers good sound with lower power use. Auracast lets you join public audio broadcasts in places like airports or gyms. Not many venues use it yet, but it makes the earbuds ready for the future.

Finally, there is a Find My Earbuds feature in the app. It plays a loud tone from a lost earbud. If you often misplace your buds in the couch, you will love this feature.

Top 3 Alternative for EarFun Air Pro 4

The Air Pro 4 is a great choice, but it is not your only option. Here are three strong alternatives at a similar price.

Soundcore Liberty 4 NC

Last update on 2026-10-16 / Affiliate links / Images from Amazon Product Advertising API

The Soundcore Liberty 4 NC is the closest rival. It offers excellent adaptive ANC that many reviewers rate slightly stronger than the Air Pro 4. It also supports LDAC, multipoint, and wireless charging.

Battery life is up to 10 hours per charge and 50 hours with the case. The Soundcore app is also very polished. However, you do not get aptX Lossless or Snapdragon Sound. If ANC matters most to you, this one is worth a look.

Soundcore Space A40

Last update on 2026-10-16 / Affiliate links / Images from Amazon Product Advertising API

The Soundcore Space A40 is small and very comfortable. It has strong adaptive noise cancelling and LDAC support. Battery life is up to 10 hours per charge, with 50 hours in total.

The tiny design makes it great for people with small ears or side sleepers. It is often on sale for a low price. The downside is that it uses an older Bluetooth version and has fewer smart features.

Sony WF C710N

No products found.

The Sony WF C710N brings Sony quality to a budget price. You get good ANC, multipoint, and the excellent Sony Sound Connect app. The sound has the classic warm Sony tuning.

It has an IPX4 rating and about 8.5 hours of battery per charge. However, it lacks LDAC and wireless charging. Choose this one if you trust the Sony brand and want a simple, reliable pair.

Sound Quality

This is where the Air Pro 4 really shines. The sound is warm, clean, and well balanced right out of the box. Most people will enjoy it without touching the EQ.

The bass has a gentle boost below 100Hz. It feels full and punchy without muddying the mids. Hip hop and electronic music sound lively but not bloated.

The mids are clear and natural. Vocals come through with good detail. Male vocals sound rich, and female vocals have a nice presence without sounding harsh.

The treble is smooth and controlled. There is a small dip around 8 to 11kHz, so cymbals can sound slightly soft. If you want more sparkle, you can raise the 8kHz slider in the custom EQ.

SoundGuys tested the earbuds with the MDAQS system from HEAD acoustics. The Air Pro 4 scored 4.8 overall, with 4.9 for timbre. These are excellent scores, even compared to premium earbuds that cost three times more.

The Air Pro 3 had problems with distortion. The Air Pro 4 fixes this. Music stays clean even at high volume.

One small issue is that the sound changes when you turn ANC off. Frequencies below 500Hz become quieter. If you often use the earbuds without ANC, you may want to add a little bass in the EQ.

If you have an Android phone with aptX Lossless or LDAC, you can stream music at much higher quality. Fans of Tidal, Qobuz, or Apple Music on Android will hear more detail. The difference is subtle, but it is real with good recordings.

Active Noise Cancellation Performance

Good ANC is hard to find under $100. The Air Pro 3 struggled here. The Air Pro 4 shows a big improvement in this area.

EarFun calls its system QuietSmart 3.0. The company claims it can reduce noise by up to 50dB. In real tests, the strongest ANC setting cut outside noise loudness by about 75%. That is a very noticeable drop.

The ANC works best on low frequency sounds. Bus engines, airplane hum, and air conditioners fade away well. Higher pitched sounds like voices and keyboard clicks still come through a bit.

You get several ANC modes to choose from:

• Strong ANC: The highest level, best for planes, trains, and busy streets.
• Balance ANC: A softer level that feels less intense for long sessions.
• AI Environment Adaptive ANC: It adjusts strength based on the noise around you.
• AI Ear Adaptive ANC: It adjusts based on how the earbuds fit in your ears.
• Wind Noise Reduction: This mode cuts wind noise during outdoor runs or bike rides.

There are also two Ambient Sound modes. The Default mode boosts outside sounds so you can hear traffic and announcements clearly. The Natural mode sounds closer to wearing no earbuds at all.

The ANC is not as strong as the Sony WF 1000XM5 or AirPods Pro 2. But those cost two to three times more. For a budget pair, the Air Pro 4 delivers very respectable noise cancelling for commuting and office work.

Codecs and Connectivity

The connectivity features are the biggest selling point of the Air Pro 4. No other earbud at this price offers such a wide codec list.

You get aptX Lossless, aptX Adaptive, LDAC, AAC, SBC, and LC3. That covers almost every phone on the market. Each codec has a clear role.

aptX Lossless streams CD quality audio without compression. It needs a phone with Snapdragon Sound support, such as many Snapdragon based Android flagships. LDAC works on most modern Android phones and delivers high resolution audio up to 990kbps.

iPhone users should know one thing. Apple only supports AAC, so you will not get aptX or LDAC. The earbuds still sound great on iPhone, and the connection stays stable. You just miss the high resolution codecs.

Note that LDAC and multipoint may not work together on every setup. You may need to choose between top audio quality and dual connections. This is common on many earbuds that support LDAC.

Bluetooth 5.4 gives a stable and efficient connection. Testers used the earbuds with an iPhone and a MacBook at the same time with no dropouts. The range is good inside a home or office.

Pairing is simple. Place the buds in the case, open the lid, and hold the case button for three seconds. Then select the Air Pro 4 in your Bluetooth list. To reset, hold the button for about eight seconds until the lights flash quickly.

EarFun Audio App and Customization

The EarFun Audio app is free on Android and iOS. It adds a lot of value to the earbuds. Many budget brands offer basic apps, but this one feels complete.

The home screen shows battery levels for each bud and the case. From there, you can switch between ANC modes and Ambient Sound modes. Firmware updates also happen here, and they take about four minutes.

The equalizer is the star feature. You get 30 EQ presets that cover bass boost, treble boost, vocal boost, and more. There is also a 10 band custom EQ for full control.

If you are not sure how to use an EQ, try My Sound Profile. This feature runs a short hearing test. Then it builds a sound profile that matches your ears. It is a simple way to get better sound with no guesswork.

Newer firmware also adds EarFun Tones. These are custom sound cues that the team refined over eight months. They make the beeps and alerts sound nicer and more musical.

You can customize the touch controls for each earbud. Single, double, triple, and long press actions are all adjustable. This lets you fix the sensitive single tap issue mentioned earlier.

Other settings include game mode, in ear detection, and Find My Earbuds. You can also turn on or off multipoint connection. The app is clean and easy to understand. Overall, it gives you more control than many apps from bigger brands.

Battery Life and Charging

Battery life is another strong point of the Air Pro 4. You can use them for a full workday without worry.

EarFun rates the earbuds at 11 hours with ANC off. With ANC on, you get up to 7.5 hours. The charging case adds enough power for up to 52 hours of total listening.

Real world tests support these claims. SoundGuys ran their standard battery test and got 8 hours and 44 minutes of playback. That is above average for wireless earbuds in this class.

Your results will vary based on volume, codec, and ANC use. LDAC and aptX Lossless use more power than AAC. If you stream high resolution audio all day, expect a bit less battery life.

Fast charging is also included. A 10 minute charge gives you about 2 hours of playback. This helps a lot when you forget to charge before leaving home.

You can charge the case in two ways. Use the included USB C cable for wired charging. Or place it on any Qi wireless pad. Wireless charging is a rare and welcome feature at this price point.

The LED light on the case shows the remaining charge. The app also shows exact battery percentages for each bud. With this much battery, most users will only need to charge the case once or twice a week.

Call Quality and Microphones

The Air Pro 4 uses six microphones, three on each earbud. EarFun pairs them with an AI noise reduction algorithm and Qualcomm cVc 8.0 technology. The goal is to separate your voice from background noise.

In quiet rooms, call quality is very good. Your voice sounds clear and natural. People on the other end will hear you without any trouble.

In office settings, the mics pick up some background chatter. However, your voice stays easy to understand. This is better than many budget earbuds, which often bury your voice.

On busy streets and in windy conditions, the Air Pro 4 does a fair job. It improves on the Air Pro 3, but it still lets some noise through. Wind can still affect your voice on gusty days.

For video meetings at home, the mics work great. For quick calls on the go, they are acceptable. But if you take many important calls in loud places, you may want earbuds with stronger mic performance.

The newer Air Pro 4+ model improves call quality and adds AI translation. If calls matter a lot to you, check that version too. For most people, though, the Air Pro 4 mics are good enough for daily use.

Overall, call quality is the weakest part of the package. It is not bad, but it does not match the excellent sound and battery performance.

Gaming and Video Performance

Many people use earbuds for gaming and watching shows. Audio delay can ruin both experiences. The Air Pro 4 handles this well.

Turn on game mode in the EarFun app. It lowers latency to about 50 milliseconds. At this level, most people will not notice any delay between sound and action.

Mobile games like PUBG Mobile, Call of Duty Mobile, and Genshin Impact feel responsive. Gunshots and footsteps match the action on screen. The wide soundstage also helps you hear where sounds come from.

For video streaming, the experience is smooth even without game mode. Netflix, YouTube, and Disney+ apps adjust for Bluetooth delay automatically. Dialogue stays in sync with lip movement.

The balanced sound tuning also works well for movies. Explosions have good bass punch. Dialogue stays clear thanks to the strong midrange.

aptX Adaptive also helps here. It adjusts the bitrate based on your connection and lowers latency on supported Android phones. This gives you a stable link in crowded wireless spaces.

Keep in mind that game mode may reduce audio quality a little. It also may not work with some codecs at the same time. For competitive PC gaming, a wired headset or a 2.4GHz dongle headset is still better. But for casual gaming and binge watching, the Air Pro 4 is a very solid companion.

Pros and Cons

After testing every feature, here is a clear summary of what works and what does not.

Pros

• Excellent sound quality: The warm and balanced tuning scored very high in lab tests. Most listeners will enjoy it straight out of the box.
• Huge codec support: aptX Lossless, LDAC, aptX Adaptive, AAC, and LC3 are all included. No rival at this price offers more.
• Strong battery life: You get up to 11 hours per charge and 52 hours total. Fast charging gives 2 hours from just 10 minutes.
• Good adaptive ANC: Noise cancelling cuts about 75% of outside noise. Five ANC modes give you plenty of choice.
• Wireless charging: The case works with any Qi pad. This is a rare perk for budget earbuds.
• Feature rich app: The app has 30 presets, a 10 band EQ, and a hearing test. You can also customize every touch control.
• Multipoint and Fast Pair: You can connect two devices at once and pair quickly on Android.

Cons

• Average call quality in loud places: Street and wind noise can leak into calls. Quiet rooms are fine, but busy areas are a challenge.
• Sensitive touch controls: The default single tap changes volume by accident. You will want to adjust this in the app.
• Sound shifts with ANC off: Bass drops when you disable noise cancelling. You may need an EQ tweak to fix it.
• High resolution codecs need Android: iPhone users only get AAC. They miss out on one of the main selling points.

Who Should Buy the EarFun Air Pro 4

The Air Pro 4 suits many types of listeners. But it fits some people better than others.

Android users get the most value. If your phone supports aptX Lossless or LDAC, you will enjoy high resolution audio that rivals premium earbuds. Snapdragon Sound phone owners get the full experience.

Budget conscious music lovers should look closely. You get sound quality that beats many $150 earbuds. The detailed EQ also lets you shape the sound exactly how you like it.

Commuters will appreciate the ANC and long battery life. A full day of travel is easy with 52 hours of total playback. The adaptive modes also adjust to buses, trains, and offices.

Remote workers benefit from multipoint. You can switch between your laptop and phone without re-pairing. The mics work well for meetings in quiet rooms.

Gym goers get IPX5 protection against sweat. The lightweight fit stays comfortable during most workouts.

However, some people should look elsewhere. Heavy callers in noisy places may want earbuds with better mics. iPhone users can still enjoy the Air Pro 4, but they might prefer AirPods for tighter Apple integration.

People who need the strongest ANC possible should consider premium options like the Sony WF 1000XM5 or Bose QuietComfort Ultra Earbuds. Those cost much more, but they block noise better. For everyone else, the Air Pro 4 is a smart and safe buy.

Final Verdict on EarFun Air Pro 4

Last update on 2026-10-16 / Affiliate links / Images from Amazon Product Advertising API

The EarFun Air Pro 4 proves that great earbuds do not need a premium price. It delivers sound, features, and battery life that compete with models costing over $200.

The sound quality is the highlight. It is warm, detailed, and fun to listen to. The lab results back this up with some of the best scores in the budget category.

The codec support is unmatched at this price. aptX Lossless and LDAC give Android users access to real high resolution audio. Bluetooth 5.4 and LE Audio also make the earbuds ready for future devices.

The ANC is a big step up from the Air Pro 3. It is not class leading, but it handles commutes and offices well. The battery life, wireless charging, and feature packed app add even more value.

There are a few small flaws. Call quality in noisy places is just average. The touch controls need a quick adjustment. And iPhone users miss out on the best codecs.

Still, these are minor issues for a pair that often sells for under $80. If you want the most features for your money, the Air Pro 4 is one of the best budget earbuds you can buy right now. It earns an easy recommendation.
