EarFun Air 2

Affordable, bass-emphasising True Wireless in-ears with LDAC

In a nutshell

For an attractive price, the Air 2 EarFun offers wireless in-ears which support both AAC and the premium audio codec LDAC. Multipoint connections, a low-latency gaming mode and connection with an app that offers sound and earpiece settings are some of the features of these comfortable earphones.

  • Comfortable fit
  • IPX7 water and sweat resistant earpiece
  • Fast charging function
  • Multipoint
  • App connection
  • Supports AAC and LDAC
  • Sensitivity to wind when making calls
  • No manual on/off switching of the in-ears possible

Available in white or black, the EarFun Air 2 are pleasantly light, weighing just 4.5 grams per side. You can individually adjust their fit to suit your ears using the included silicone ear tips. These come in four different sizes and promote a stable fit.

These earphones are equipped for sporting activities thanks to a water and sweat-resistant finish in accordance with IPX7, and they are also protected against weather-related moisture.

Battery life

The EarFun Air 2 can achieve a listening time of six and a half hours at a high volume setting when using the AAC codec. These in-ears can also be fully charged three times in their case, which makes a total runtime of 26 hours. Meanwhile, a ten-minute quick charge provides capacity for one and a half hours, and the in-ears are fully recharged after around 50 minutes. The case’s battery reserve can also be restored quite quickly, after 70 minutes, and this uses the USB-C to USB-A charging cable that is supplied. Alternatively, you can use a charging mat to power up the case wirelessly via Qi.


These wireless in-ears support Bluetooth standard 5.3 as well as multipoint connections with two devices simultaneously and one-sided use in single mode. The wireless connection offered sufficient stability to cross several rooms, while there was a range of 25 metres outside in the garden.


In the factory settings, the touch-sensitive headphone surfaces can be used to control playback, skip forwards and backwards through track selection, adjust the volume and call up the voice assistant. You can also answer and end calls. The touch control can be customised to suit personal preferences via the app, and this was executed in an exemplary manner. You also have the option of activating or deactivating the gaming mode directly via the headphones. However, because you cannot manually switch the earbuds on and off via the touch surfaces, you always need to have the case with you.

EarFun Audio app

To customise the sound of the EarFun Air 2, the app (for Android and iOS) offers a choice of ten preconfigured settings: “Rock”, “Pop”, “Country”, “R&B”, “Classical”, “Jazz”, “Bass Boost”, “Bass Cut”, “Treble Boost” and “Treble Cut”. An EQ with ten bands also allows you to make your own settings, and these can be saved as pre-sets, which was great.


In addition to touch control, the app can also be used to configure the microphone technology for single operation. You can switch Multipoint connections and the latency-reduced gaming mode on or off, and you can carry out firmware updates. While you can use a beep search function to help you find the headphones, there is also the option to adjust the volume of voice announcements. On Android devices, the LDAC codec can be activated if this is supported by your smartphone or tablet.

However, the standard model does not offer environment control with Active Noise Cancellation (ANC) and transparency mode, unlike the EarFun Free Pro 3 and EarFun Air Pro 3.

Voice clarity during phone calls

According to the manufacturer, these wireless in-ears have two microphones with ENC technology (Environmental Noise Cancellation) on each side, but these are quite sensitive to wind, making it difficult to hear your voice in strong gusts. This technology worked better with louder background noises, as these were slightly attenuated so that communication remained possible. On the other hand, in a quiet environment, there was solid speech intelligibility, even if voice transmission was more authentic with the Pro models (see above).


The EarFun Air 2 are tuned for fun and offer a full, rich reproduction with a rich bass range thanks to their rather large, dynamic 10mm wool composite drivers. The low bass, in particular, seemed quite voluminous, but this was not always an advantage, and they could seem a little too powerful and uncontrolled when listening to particularly bassy music. However, this could be remedied by slightly reducing the lower bass range with the EQ, as this made the playback sound more powerful and defined. Apart from that, the tuning worked well and sounded harmonious.

The fact that the mid-range had an appealing clarity and did not seem diffuse or cramped despite the richness of the sound was very successful. On the contrary, the clean, tidy presentation made it easy to perceive details such as gripping noises when listening consciously. There was also assertiveness for mobile use, with voices being reproduced as full-bodied with a pleasant warmth.

The upper registers were also powerful and did not flatten out, which gave a fresh, lively impression and provided accents. It was noticeable that sibilants appeared to be somewhat more concise at higher volume levels, and there was a tendency to develop towards peaks. However, in the normal listening range, the treble reproduction blended in perfectly harmoniously, resulting in a good-natured sound character.


If you are looking for good-sounding, powerful bass True Wireless in-ears that don’t cost too much money and are not dependent on Active Noise Cancellation, you should definitely take a closer look at the EarFun Air 2. These weatherproof headphones can be flexibly adapted to suit your own preferences via an app and scored points from us with their high-quality audio codecs, multipoint connections and low-latency gaming mode. The handy case was also suitable for wireless charging. However, you should pay attention to their susceptibility to wind when making phone calls.
