, ,

9.1/10 average rating

True wireless earbuds are something that everyone is getting into these days, partly due to phone manufacturers killing the headphone jack. That gives the chance for some manufacturers such as EarFun to come out with some wireless earbuds at an affordable price. The EarFun Free True Wireless Earbuds come with up to 30+ hour battery life giving users 6 hours of playback through the earbuds and 4 extra charges from the charging cradle. The sound is pretty good and also pair easily with your device. Continue to read our full review below.

The EarFun Free True Wireless Earbuds have a pretty simple design that makes it look like many other truly wireless earbuds out there. Sure, other companies have their own design versus what EarFun has and that’s what makes this design different from anyone else.

When looking at the earbuds, you’ll notice EarFun’s logo with a small LED light indicator. The indicator lets users know when it’s ready to pair (flashing blue), paired (solid blue), or charging (solid red). Just below that is the microphone for those who will be using the earbuds for phone calls.

The entire unit has a plastic feel to it and should be able to withstand some drops and or scratches. The earbuds are also IPX7 sweat and water-resistant. The other half of the earbud leads to the gel eartip where the driver sits in your ears. On the underside, you’ll see three gold pin connectors for charging the earbuds in the charging case. There’s also an “L” and an “R” indicating which ear they go in.

Moving on to the charging case, it’s small enough to fit in your pocket without it feeling too bulky. The top cover has EarFun’s logo on it as well. The front of the case has 4 LED indicators showing off how much battery life is left for the case. Above those same indicators is an indent for opening up the case. After opening the case, you’ll see “L/R” again for earbud placement. The wireless earbuds sit nicely in the case and don’t require any force to take them out or set them in for charging. There’s nothing along the side of the case and the USB Type-C charging port is on the back.

When they sit in your ear, they feel comfortable but after long use, about an hour or so, they did start to hurt my ears a bit. Keep in mind that may not be the case for everyone but my ears did get irritated over time.

Ease of Use

Pairing the units was simple enough and shouldn’t cause anyone trouble when connecting to a device for the first time. The earbuds won’t be in the case to begin with, but all you need to do is place them in the cradle and then take them out. The units will flash blue letting users know that it’s ready to be paired. After being paired to the device you’re using, the earbuds are ready to go.

As far as function goes on the EarFun Free’s, the left and right earbuds do have their own controls. Such as powering on the device will require you to hold the button on the left and right earpiece to power on if you didn’t place them in the charging cradle. For powering them off, the right earpiece button will need to be held down for 4 seconds. Music playback is all done on the left earbud such as pausing is one press, skipping to the next song is two presses and going back to the previous song is three presses. The right earbud can also pause and play music but it’s more used for hands-free conversations or using your device’s voice assistant. One press on the right earbud will either answer or end a phone call and two presses will bring up your voice assistant. Unfortunately, there is no volume control, so you will need to use the volume rocker on the device that is paired with the earbuds.

If you do plan on pairing these with another device, you will need to hold down the button on the right earpiece for 5 seconds to re-enter the pairing mode. After that, pair the earbuds with the new device.


When it came to how the EarFun Free True Wireless Earbuds sounded, I was impressed. Now, I know I say that for other headsets too but for a company I have no clue about that’s selling on Amazon, you don’t really expect much until you truly get to hear how each headset sounds.

Since the earbuds come with 6mm drivers, it pushes out sound like a headset with a bigger driver could. Songs that had highs and mids sounded great along with the lows. While playing through different genres of music, there was no distortion or muffled noise that can interrupt music playback.

For those that may be wondering if these have enough bass in them than other true wireless headsets out there, the answer is yes. Keep in mind that it won’t be like Bose, JBL, or Beats bass levels, but there’s enough bass and you’ll definitely notice it.


Thanks to the earbuds having Bluetooth 5.0, the reception is good. As per EarFun’s specificatons, you can go up to 49 feet or 15 meters but that’s within line of sight and nothing in the way such as walls or any other objects. I didn’t go a full 50 feet but I did walk around the house with walls in the way and the earbuds didn’t have any connection issues such as breaking up because I walked out of range.

Call Quality

True wireless earbuds tend to be a hit and miss when it comes to calling quality. When taking calls with the EarFun Free’s, I was able to hear everyone loud and clear and didn’t need to have anyone repeat themselves. As for those on the other end of the call, they kept telling me I was sound as if I was far away and that there was a slight echo when someone is talking.

I did unpair and then repair the earbuds to the same phone (Galaxy S10) and ended up having the same issue. Because of the same issue I decided to it with another phone (iPhone XS) and ended up with the same results. This could be an issue with the pair that I had, but after a while, anyone I talked to got used to how it all sounded.

Battery Life

Battery life is pretty important to when it comes to any headphones and the fact that EarFun has the Free’s have up to 30-hour battery life will surely have you listening to your music or watching videos for long periods of time.

Each earbud comes with a 50mAh battery that’ll get you up to 6 hours of playback depending on the environment. I got pretty close to 6 hours when using them over time and that wasn’t just once. That was after charging the earbuds back to 100% battery each time.

The case itself has a 500mAh battery that’ll get you 4 extra charges out of the earbuds. When you do end up charging the earbuds, it does take about an hour and a half depending on how depleted the battery is. Charging up the case to a full battery, on the other hand, will take about 2 hours to charge up with the included USB Type-C cable.

The cradle does have the ability to charge wirelessly with a charging pad but when testing the charge time, it also took about 2 hours to charge to a full battery.


EarFun is offering the Free True Wireless Earbuds for a discounted price of US$39.99 on Amazon at the time of posting this review. This is $40 off the full retail price of US$79.00. Considering the price is affordable, I can see these being an easy purchase for anyone who is looking into getting some true wireless earbuds for the first time without spending too much on brand name devices.

Wrap Up

Overall, EarFun has come out with some pretty good true wireless earbuds for US$80. I like the sound and believe anyone who gets these will be pleased too. Other than them hurting my ears a bit I don’t have any other issues.
