Earfun Free 2 Review

With the Earfun Free 2 in-ear headphones, the Chinese manufacturer sends a successor to its excellent first-budget in-ear headphones into the race. For me, Earfun is one of the most promising up-and-coming audio manufacturers from China, which consistently scores good products for both headphones and speakers. Failures such as we have already had to experience at Tronsmart or TaoTronics have not yet occurred here.

Packaging & scope of delivery
The Earfun Free 2 comes in a classic white/yellow cardboard box, inside of which you will find the headphones with charging case, three pairs of earpads, a USB-C charging cable, and a multilingual user manual. The headphones arrived undamaged. We ordered directly from the Earfun shop, but the headphones are, of course, also available from Amazon.


  • Exceptionally low latency – perfect for gamers.
  • Design that is both compact and ergonomic.
  • The voice quality is excellent.
  • Waterproof.


  • Bass and dynamic range are lacking in the audio.

Design & processing

As mentioned at the beginning, Earfun does a lot of things right, in my opinion. This also applies to the design in combination with product names and the product portfolio in general. If you compare it with other manufacturers, it’s not that big (luckily!), Clear and structured.

In my opinion, it only makes sense that the EarFun Free 2 wireless in-ear headphones keep the same shape as their predecessor. The earbuds have a very classic bud design similar to the AUKEY EP-T1 (the first wireless in-ear from AUKEY).

However, Earfun has slightly modified the Free 2. The charging case is now less comprehensive but marginally higher, and the (touch) control buttons are now somewhat triangular where previously round buttons were found.

So optically, the Earfun Free 2 is not a significant innovation, which I think is good. So the model series remains visible, and Earfun has also focused on technical innovations, which I welcome.

In terms of workmanship, I have not had anything to complain about at Earfun so far. This will not change with the Earfun Free 2 either. The headphones have no defects in material or workmanship – outstanding!

Sound of the Earfun Free 2

Like their predecessor, the Earfun Free 2 is equipped with a dynamic driver. In the test, the headphones with aptX codec deliver an excellent sound, as I think. It offers rich bass down to the sub-bass range and is a lot of fun with electronic music, which the Earfun Free 1 was also good at.

In the midrange, sound voices are complete but a touch too bassy compared to reality. Depending on your taste, this doesn’t have to be a disadvantage. In the high-frequency range, in my opinion, the headphones score the most from the aptX implementation. Here it sounds more detailed than its predecessor and delivers an audibly broader frequency spectrum.

For a low price range, you can also get the Soundpeats T2, for example. This wireless in-ear comes with, considering the price, quite good active noise suppression, but the aptX codec is missing, making a difference in quality, at least for Android phones with Qualcomm chips.

The sound peats sound very similar in the low and midrange, but the Erafun Free 2 delivers an audibly more clear high tone, making the headphones sound a bit more brilliant overall. The sound is more identical with Apple devices, but I can still see the Free 2 slightly ahead. Overall, however, both headphones are recommended. Unfortunately, you are spoiled for choice. Would you prefer a little better sound or a somewhat better shielding from ambient noise by the ANC?


The Earn Free 2 are equipped with two microphones (one microphone per listener). In addition, thanks to the Qualcomm chip, the latest CVC 8.0 noise suppression is also used, which reduces background noise and emphasizes your voice during phone calls.

During my test calls, the headset worked well overall. In addition, the Earfun Free 2 reliably suppresses or reduces normal background noises so that your conversation partners can understand you well. So the headphones are also suitable for longer phone calls!


The comfort of Earfun Free 2 Bud design handset like that in the test is pretty good! However, due to the weight distribution, in which almost 100% of the weight is above the ear cushions, the weight of 5.8 g pushes the listener into the ear rather than out.

At least that’s the case with me. But, as always, they are wearing comfort is a very individual matter and differs from ear shape to ear shape. The listeners also offer a pretty good shielding from the outside world even without ANC.

Now with touch operation
While the first generation of the Earfun Free is still equipped with push buttons, the EarFun Free 2 uses touch sensors, as is the rule now. Like its predecessor, the Earfun Free 2 also shone in the test with a comprehensive operating option range.

The touch sensors react precisely, but fortunately, they are not too sensitive either. This saves the Earfun Free 2 from having to use the bar like the Tribit FlyBuds BTH 90.

Bluetooth 5.2 with aptX & range

When it comes to Bluetooth, the Qualcomm QCC3040 is used, which is built into the most inexpensive headphones with active noise cancellation. Unfortunately, such ANC technology is not installed here, even if the chip theoretically supports it.

In comparison, Earfun decided against a Qualcomm chip for the predecessor, so I’m all the more pleased that a very current Bluetooth 5.2 chip with aptX Adaptive and correspondingly low latency mode is installed here. This mode reduces the transmission latency from the regular 200 ms to 60 ms and thus offers its advantages during video streaming or mobile gaming.

The reduced latency is at the expense of the Bluetooth range and the transfer rates, so I recommend that you only use this mode in clear cases.

In the test, I achieved a stable connection range of around 15 meters in open space in normal mode. It is correspondingly less in closed rooms. Thanks to the stable connection quality, the headphones are also suitable for jogging or generally for sport in the test. Moreover, with IPX7 certification, the Earfun Free 2 headphones are also protected against the ingress of water/sweat.

Battery Life

With 50 mAh per handset, the battery capacity in the handset has not changed for the time being. Nevertheless, Earfun was able to significantly improve the runtime of the listener with the more modern, more energy-efficient Qualcomm chip.

While the battery of the Earfun Free 1 lasted about 5 hours in the test, I was able to achieve a runtime of about 6 to 6.5 hours in the trial of the Earfun Free 2 , with a mixed volume of 50% -70%. At a slightly lower volume, the factory specification of 7 hours is quite realistic.

The battery capacity of the charging box is slightly lower at 400 mAh, which benefits the weight of the case. Because the total running time with the charging cradle is still roughly the same due to the longer running time of the handset of up to 30 hours. In the test, it took about 1.5 hours to fully charge the earphones in the charging box.

The case of the Earfun Free 2 can be charged either wired via USB-C cable or wirelessly. Most manufacturers reserve a nice feature for their top models and is rarely found in this price range. However, the charging process of the case wirelessly takes around 3.5 hours, almost twice as long as wired.


The Earfun Free 2 is another successful product from Earfun for my taste. Since the first product with continuous quality, the Chinese manufacturer has convinced me both for headphones and speakers.

Design and workmanship are the solid standards, nothing special, but Earfun has not made a mistake so far and consistently delivers good quality.

In terms of sound, Earfun improved again compared to its predecessor, probably mainly due to the built-in Qualcomm chip and aptX support. It delivers a high-resolution tweeter, solid mids, and rich bass for a budget in-ear with a single dynamic driver. The entire operation via touch sensors, which worked very well in the test, should also be mentioned positively.

Although the built-in chip would be able to do this, Earfun decided against an ANC. If you can do without this, the Earfun Free 2 delivers one of the best sound images in this price range for my taste. If you want ANC, you get this at a similar rate with the Soundpeats T2, but you have to live with a slightly less detailed sound.
