The EarFun Free Truly Wireless are decent truly wireless headphones. They have a bit of a bass-heavy sound profile, and their vocal reproduction is a bit recessed. They offer a decent total battery life and are decently comfortable for in-ears. However, they won't be great for watching video content as they have a noticeable delay and aren't the best option to block out ambient noise. Nevertheless, they're a good option for someone who isn't looking for premium, truly wireless headphones.
Our Verdict
The EarFun Free Truly Wireless are okay for mixed usage. These headphones have a pretty good audio reproduction, although they're a bit bass-heavy. They're very easy to carry around, thanks to their truly wireless design. They're also great for sports since they're very breathable and have a stable fit. However, they aren't designed for gaming and won't be ideal for phone calls either.
- Stable and breathable design for sports.
- Very portable.
- Low leakage.
- Four additional charges from the case.
- Lack of volume control.
- Plasticky design.
- Sub-par noise isolation.
The EarFun Free are alright for neutral sound. These headphones have a well-balanced audio reproduction, although they're a bit on the bass-heavy side. They'll be better suited for bass-heavy music. The in-ear fit might not be the ideal design for critical listeners, especially since the soundstage is practically nonexistent.
The EarFun Free Truly Wireless are decent for commuting or traveling. They're easy to carry around and are decently comfortable for in-ears. However, their noise isolation is sub-par and won't block out much noise. Their battery life is a bit short for long flights but should be more than enough for your daily commute.
The EarFun Free are great for sports. These buds are small, breathable, and offer a stable fit. They won't make you sweat more than usual and are easy to bring around to the gym. Their wireless design is also great for freedom of movement, and they're very lightweight.
The EarFun Free are okay for the office. While they can reduce ambient chatter well, their battery life won't be long enough for a full workday. Their fit might also not be the most comfortable to wear for hours.
The EarFun Free have very high Bluetooth latency and shouldn't be used for wireless gaming.
The EarFun Free are Bluetooth-only headphones and you can't use them wired.
The EarFun Free Truly Wireless are mediocre for phone calls. The microphone struggles to separate ambient noise from recorded speech, so be sure to make calls in very quiet conditions. Also, recorded speech sounds muffled and lacks detail but is still understandable.

Popular Headphones Comparisons
The EarFun Free are good budget truly wireless headphones. They have a pretty good sound quality and are quite comfortable for cheap in-ears. However, they don't have a great passive noise isolation performance and they feel a bit plasticky.
See our recommendations for the best true wireless headphones, the best wireless Bluetooth earbuds, and the best earbuds for bass.
The EarFun Air Pro True Wireless are better for most uses than the EarFun Free Truly Wireless. The Air Pro have better build quality, better controls, an impressive noise isolation performance, and a longer continuous battery life. They also have a more neutral sound profile, which some listeners may prefer. On the other hand, the Free have a more bass-rich sound, which may please fans of genres like EDM and hip-hop. They also leak much less audio at high volumes.
The EarFun Free Truly Wireless and the SoundPeats TrueFree/True Wireless are two fairly similar budget truly wireless headphones. The SoundPeats feel a bit better built, and more stable thanks to their very small bud design, and they also isolate better against ambient noise. Although both headphones have a bass-heavy sound profile, the EarFun are a bit better balanced and more neutral. They also have better battery life and charge via USB-C.
The Samsung Galaxy Buds are way better truly wireless headphones than the EarFun Free Truly Wireless. They're more comfortable, better built, more stable, and offer a more neutral sound quality, which you can easily EQ in their Android app. The Samsung fit also has a better isolation performance and they offer more battery life on a single charge, though the case only offers one additional charge. Other than price, there's no real reason to get the EarFun over the Samsung.
The Anker SoundCore Liberty Lite Truly Wireless are slightly better-performing headphones than the EarFun Free Truly Wireless. Their isolation performance is great and they feel better built than the EarFun. They're also slightly more stable thanks to the stability fin sleeve options and they have a more neutral sound. On the other hand, the EarFun are slightly more comfortable due to their design and they offer more battery life.

Test Results
The EarFun Free earbuds are pretty bland truly wireless headphones. They have an all-black or all-white design that doesn't particularly stand out. They're very small buds that don't protrude out of the ears. The manufacturer's logo is on the button on each bud, but this won't be very noticeable.
These are decently comfortable earbuds. They're very lightweight and small, which means they don't put much pressure inside your ear. The controls are also very easy to press, meaning you don't have to push the buds into your ear canal for commands to register.
The EarFun Free Earbuds' control scheme is a bit basic and lackluster. Unlike the FIIL T1X True Wireless, they don't have a volume function, which can be a deal-breaker for some. There's a single button on each bud that lets you control your music and manage your calls as well. The buttons are fairly clicky, but the buds don't offer any audio cues for commands, which is a bit disappointing.
Like most truly wireless headphones, these small buds don't trap heat inside or around your ears. This makes them a very breathable option, which is optimal for sports.
Like most truly wireless headphones, the EarFun Free buds are very small, making it easy to carry them in your pants pockets or a bag wherever you go.
Their case is decent. It's entirely made of plastic and is a bit bigger than the cases that come with some other truly wireless earbuds, but you should still be able to put it inside your pockets. It has a 4-light battery indicator, which is nice. If you want something similar with a case that you can charge wirelessly, check out the TOZO T10 Truly Wireless, though they don't perform quite as well overall.
They're decently well-built headphones. They're made out of plastic, but they feel dense enough to survive physical damage from accidental falls. They're also rated IPX7 for water resistance. If you want something similar that feels a bit better-built, check out the TOZO T6 Truly Wireless.
Although they don't have any stability fins, the EarFun Free earbuds are stable enough for sports. Their small bud design fits snugly inside the ear, and they come with three other tip options for you to find the best fit.
- EarFun Free headphones
- Charging case
- 3x tip options
- USB-A to USB-C charging cable
- Manuals
These headphones have a decently well-balanced sound profile, although it's on the bass-heavy side. These headphones will be more suitable for bass genres like EDM or even hip-hop and might not be the best option for people who care about the clarity of vocals.
Like most in-ear headphones, they have incredible frequency response consistency. This means that they perform pretty much the same way every time you use them, and they perform well on different users.
The bass accuracy is alright. It's well-balanced but slightly over our neutral target curve. Users might hear extra thump and rumble, which fans of bass might like.
The EarFun Free's mid accuracy is excellent. It's fairly well-balanced, but vocals might feel at the back of the mix and won't sound as clear.
Their treble accuracy is good. The response is fairly even, but higher frequencies and sibilants (S and T sounds) like cymbals might feel a bit sharp for some people.
The EarFun Free have a good peaks/dips performance. There's a bit of overemphasis in the bass range, which makes them sound a bit warm, especially mixed with the wider dip in the mid-range. This makes the vocals and lead instruments pushed to the back of the mix while emphasizing the lower-end frequencies. There are also a few peaks in the treble range, making sibilants (S and T sounds) a bit sharp and piercing.
They have a fantastic imaging performance. The group delay is below the audibility threshold, which results in a tight bass and transparent treble range. Our unit's L/R drivers were also very well-matched, which is important for the localization of objects in the stereo image. These results are only valid for our unit, and yours may perform differently.
Their passive soundstage performance is bad. It's because creating an out-of-head and speaker-like soundstage is largely dependent on activating the resonances of the pinna (outer ear). The design of in-ears and earbuds means their sound fully bypasses the pinna and doesn't interact with it. Because these headphones have a closed-back enclosure, their soundstage won't be perceived to be as open as that of most open-back earbuds, like the Apple AirPods (2nd generation) Truly Wireless, Google Pixel Buds 2017 Wireless, or the Bose SoundSport Free Truly Wireless.
The EarFun Free's weighted harmonic distortion performance is decent. It's within very good limits in the bass range but slightly gets elevated in higher frequencies, although this shouldn't be audible to most people. There's also no big jump under heavier loads, which is great.
Their noise isolation performance is sub-par. They don't have active noise cancellation, and their passive isolation is quite disappointing. They won't be ideal for blocking out the noise in public transit as they don't reduce the deep rumble of a bus or train. They're decent for an office setting as their fit reduces ambient chatter and the noise coming from the A/C.
The EarFun Free's leakage performance is superb. These in-ears practically don't leak, so you don't have to worry about others being bothered by what you're listening to. However, blasting your music in very quiet environments like a library still isn't recommended.
The EarFun Free's integrated microphone's recording quality is reasonable. Recorded speech sounds muffled and lacks detail, although it's still possible to understand what's being said.
The microphone's noise handling performance is sub-par. The mic struggles to separate ambient noise and actual recorded speech. This means that these headphones will only be suited for phone calls in a very quiet environment.
The EarFun Free have a mediocre battery performance. Their battery lasts for just over four hours of continuous playback on a single charge, which is slightly disappointing as they're advertised to last for six hours. However, battery performance can vary with real-life use, so your experience may vary. On the upside, they have a standby mode after being idle for a few minutes. Also, the charging case holds about four additional charges.
The EarFun Free don't have any dedicated companion app for customization options.
The EarFun Free have adequate Bluetooth connectivity. They have a good line of sight range, so you shouldn't have any issues, especially if you usually keep your source near you. However, they have very noticeable latency, meaning they won't be ideal for watching video content. On the upside, you might get better overall performance if your source also supports Bluetooth 5.0.
As expected, these truly wireless headphones don't have an audio cable, and you can't use them wired. They only come with a 1.6ft USB-C charging cable.
These headphones aren't compatible with a PS4 or a PC. However, they work with PCs that are Bluetooth-compatible.
You can't use these headphones with an Xbox One.
These headphones come with a charging case that serves as a charging station, which you can bring wherever you go. It stores about four additional full charges for the headphones, which is very helpful.
