The EarFun Free 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.
Decent 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.
Decent for neutral listening. 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. Also, the in-ear fit might not be the ideal design for critical listeners, especially since the soundstage is practically nonexistent.See our Neutral Sound recommendations
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.See our Commute/Travel recommendations
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.See our Sports/Fitness recommendations
Okay for the office. While they can reduce ambient chatter well, their battery life won't be long enough for a full work day. Their fit might also not be the most comfortable to wear for hours.See our Office recommendations
These are Bluetooth-only headphones and can't be used wired.
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.
The EarFun Free 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.
The EarFun Free Earbuds are decently comfortable, especially for in-ear headphones. 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. They don't have volume control, which can be a deal-breaker for some. There's a single button on each bud which 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 other truly wireless headphones, these small buds don't trap heat inside or around your ears, making them a very breathable option, which is optimal for sports.
Like all 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.
The EarFun Free's case is decent. It's entirely made of plastic and is a bit bigger than other similar truly wireless designs, but you should still be able to put it inside your pockets. It has a 4-light battery indicator, which is nice.
The EarFun Free are decently built headphones. They're made out of plastic, but they do feel dense enough to survive physical damage from accidental falls. They're also rated IPX7 for water resistance, although we don't test this internally.
Although they don't have any stability fins, the EarFun Free 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.
The EarFun Free have a decently well-balanced sound profile, although it's a bit 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, the EarFun Free have amazing 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 too.
The bass accuracy is great. It is well-balanced, but slightly over our neutral target curve. Users might hear extra thump and rumble, which fans of bass might like.
The mid accuracy of the EarFun Free is very good. It's fairly well-balanced, but vocals might feel to be at the back of the mix and won't sound as clear.
The treble accuracy is also great. 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 decent 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 putting more emphasis on the lower-end frequencies. There are also a few peaks in the treble range, which could make sibilants (S and T sounds) a bit sharp and piercing.
The EarFun Free's stereo imaging is excellent. 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. Note that these results are only valid for our unit, and yours may perform differently.
The EarFun Free's soundstage is poor. This is 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 is in such a way that fully bypasses the pinna and doesn't interact with it. Also, because these headphones have a closed-back enclosure, their soundstage won't be perceived to be as open as that of open-back earbuds like the Apple AirPods 2 Truly Wireless 2019, Google Pixel Buds 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.
The EarFun Free's noise isolation is sub-par. They don't have any 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 excellent. 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 microphone performance is mediocre. Recorded speech sounds muffled and lacks detail, which is typical for Bluetooth microphones, especially in truly wireless headphones. It's also not suitable for even moderately loud situations like a busy street.
The EarFun Free's integrated microphone's recording quality is passable. Recorded speech sounds muffled and lacks detail. It's still possible to understand what's being said, but the recording quality is quite poor.
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.
We measured just over 4 hours of continuous playback time on a single charge, which is slightly disappointing as they're advertised to offer 6 hours. On the upside, they have a standby mode after being idle for a few minutes. Also, the charging case holds about four additional charges, which is good.
The EarFun Free don't have any dedicated companion app for customization options.
The EarFun Free are Bluetooth-only headphones. 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.
These headphones are Bluetooth-only.
As expected, these truly wireless headphones don't have an audio cable. 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.
These headphones can't be used 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 also provides up to four additional full charges for the headphones, which is very useful.
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, their small size doesn't offer great noise isolation like more high-end headphones and they do 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 Free 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 Truly Wireless are way better truly wireless headphones than the EarFun Free. They're more comfortable, better-built, more stable, and offer a more neutral sound quality, which you can easily EQ in their Android app. Their 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. 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.
The JBL FreeX Truly Wireless are better headphones than the EarFun Free. They're more comfortable, better-built, have a better-balanced sound profile, and their fit isolates better against ambient noise. On the other hand, the EarFun are Bluetooth 5.0 and have a USB-C port, but that's about it.
