Where to Buy

Introduction

EarFun was founded in 2018 by a collection of skilled designers, engineers, and music lovers. They share a goal: to develop next-generation wireless audio devices that incorporate the most cutting-edge technologies to resolve current-generation wireless audio device obstacles.

EarFun thinks that technology has the potential to enrich modern lifestyles and seamlessly integrate with our daily activities. This belief is reinforced by their tagline, “Better Sound, Better Life.” – EarFun

EarFun includes the latest R&D results into every release, including the Free Pro 2. While preserving the small form factor, they managed to “squeeze” in the intelligent advanced AIROHA audio system on a chip (SoC) for better noise cancellation performance and more stable connectivity.

It has been a “tradition” for EarFun to surprise users with all these enhancements in their models. In this article, we will find out whether these enhancements are only marketing pitches on paper or if do they deliver superior performance!

Case

Battery

  • Battery Life: 24 hours
  • Connector: USB Type-C
  • Wireless Charging: No
  • Battery Capacity: 480mAh

The Free Pro 2 case can provide an additional 4 charges to the earbuds, giving a total of 30 hours of battery life with ANC off (24 hours from the charging case and 6 hours from the earbuds).

The total playtime will reduce by around 17% if ANC is turned on. Regardless if ANC is on or off, I find the battery life is sufficiently long for my daily commute and music playback in the office.

At the back of the charging case, users will find the USB Type-C charging port. The bottom of the charging case is flat so it can stand firm when it is placed on a surface. Surprisingly, wireless charging is enabled on this model.

At the price, I did not expect wireless charging to be included.

UX

  • Can be open easily with one hand: No
  • Pass the shake test: Yes
  • Light Indicators: Display battery level and charging status

It is impossible to open the charging case with one hand due to the strong magnetic force at the lid and small form factor of the charging case. The earbuds are firmly secured in the charging case by a magnet.

LED battery life indicator

When you open or close the charging case, the LED will flash to indicate the estimated battery life

LED IndicatorEstimated Battery Level
White LED light on for 3 secondsMore than 30%
White LED light flashes for 3 timesLess than 30%
White LED light flashes for 1 timesLess than 10%
Light indicator is offLess than 5%

As a user, I find this type of battery level display confusing and I tend to charge them more often to ensure the battery level is always high. I prefer a multicolor LED indicator to display the estimated battery level.

For charging status, the white LED light flashes to indicate that the battery is charging and it turns off when the case is fully charged. This is more straightforward as compared to the battery level display.

Design

  • Shape of the case: Rectangular
  • Material: Plastic
  • Build Quality: Premium

The Free Pro 2’s charging case looks similar to the Free Pro. Instead of having a piece of reflective plastic on the case, EarFun chose to only use matte-finish plastic. The finish is smooth and the metallic paintwork further improves the attractiveness.

I prefer the matte material as it is resistant to fingerprints.

Portability

  • Weight: 38g (With earbuds inside)
  • Volume: 6.66cm x 2.5cm x 2.85cm = 47.45cm cu (~2.9 in cu)
  • Portability: Good

The Free Pro 2 are more portable as compared to their predecessor, the Free Pro, due to lighter materials used in the charging case. Besides the weight, the size of the charging case has also shrunk significantly and it is now easy for me to put it into a pocket.

Earbuds

Battery

  • Battery Life: 6 hrs (with ANC off)
  • Charge Time (15mins): 120 mins playback time

Each full charge on the earbuds will give users about 6 hours of playtime with noise cancellation on. As mentioned, I am satisfied with the battery life for daily usage. For those who need a battery life longer than 6 hours, you can simply put the earbuds back to the charging case and get another 120 minutes of playback.

Put the Free Pro 2 into the charging case for only 10 minutes and they are ready to work for another 120 minutes. Amazing!

UX

  • Control Mechanism: Touch
  • Touch Accuracy: Good (Almost always register the right action)
  • Control Symmetry on both earbuds: Yes
  • Mono Use: Yes
  • Lack of previous track control
  • Voice Assistant (Siri, Google Assistant, and Amazon Alexa) and game mode can be triggered from earbuds

I particularly like the touch controls of the Free Pro 2. The entire faceplate of the earbud is covered by the touch sensor and most of the time the earbuds will register any touches or gestures accurately.

The control is symmetrical and easy to remember. However, after going through the user manual, I can not find a way to go back to the previous track. I need to take out my phone from my pocket to go back to the previous track if I accidentally skipped it.

Either side of the Free Pro 2 can be used alone in mono mode. I find this useful when I am working out in the gym because I may need to communicate with others. Other great features of the Free Pro 2 are that users can trigger the voice assistant and game mode on the earbuds.

Under the game mode, latency is reduced significantly to maximize the sync between audio and video. I like this feature a lot, especially in video playback. I can enjoy Disney+ or Netflix shows with great audio-visual synchronization, or even with noise cancellation enabled to further improve the immersive experience.

Design

  • Profile: Medium
  • Material: Plastic
  • Comfort: Good
  • Fit: Good

The size of the earbuds is tiny and for those with smaller ears, the Free Pro 2 are definitely suitable. I can wear the Free Pro 2 for hours during work and exercise and I tend to forget that they are in my ears. The comfort and fit are perfect for me.

Mic

  • Noise Cancellation: Average
  • Voice Pick-up: Average

With the enhanced 6-microphone array, environment noise cancellation (ENC), and AI-powered noise cancellation algorithm, EarFun claims that the voice pick-up capability of the Free Pro 2 is “outstanding”.

However, after several tests, I do not have great confidence using them for calls in public. The noise suppression is insufficient to minimize surrounding noise. Furthermore, I find that there are some intermittent cut-offs of my voice when talking.

Sound

  • Driver: 6mm dynamic driver with graphene film
  • Sound Signature: Balanced
  • Sub-bass: Good
  • Bass: Average
  • Mids: Good
  • Treble: Good
  • Sound Detail: Good

Active Noise Cancellation

According to EarFun, the active noise cancellation (ANC) on the Free Pro 2 has peak noise canceling at 40dB and the innovative QuietSmart™ 2.0 technology will smartly filter ambient noise.

Based on my usage in different scenarios, the ANC is definitely not the strongest when compared to major players in the market like Bose or Sony. However, the level of ANC on the Free Pro 2 is definitely sufficient for most situations, like commuting or in a noisy office.

I am looking forward to a model from EarFun that comes with a smartphone application to adjust the noise cancellation level. I find this sort of feature useful because I do not need noise cancellation to be maxed all the time and I prefer to adjust according to my needs.

The Free Pro 2 also support an ambient sound mode. This could be useful when you need to pay attention to your surroundings. However, I find the ambient sound amplifies the surrounding noise too much, especially wind noise, and it is quite annoying to use on a windy day.

The level of ANC is definitely sufficient for most common usage scenarios, like commuting or in a noisy office.

Overall sound quality

The overall sound signature of the Free Pro 2 can be considered warm with a good emphasis on the bass region. The presentation is not overly harsh and is forgiving for those who do not have good tolerance towards overly bright treble. However, due to this tuning, the clarity of Free Pro 2 is only about average – some of the details are shadowed by the bass and users cannot “feel” the presence of those details.

Lows

The Free Pro 2 have a similar sound signature to their predecessor, the Free Pro. The bass is the dominant aspect of the overall performance. The sub-bass extends deeply, and the low-end rumble should satisfy basshead audiophiles. The mid-bass does not decay swiftly, extending for quite a while before vanishing. Overall, the bass has a full-bodied presentation and will suit those who prefer a warmer sound signature.

The rumble from the sub-bass will definitely satisfy basshead audiophiles.

Mids

The elevated bass doesn’t leave much space for midrange frequencies. The mids are colored with the warmth from the bass and are not forward. I find the tuning great for casual listening as they are not shouty.

However, for those tracks that have more bassy instruments, vocals will definitely suffer in the sea of thick bass notes. The presentation is overly smoothed and the coloration causes the transparency of the midrange to be reduced significantly.

Highs

As compared to the mids, the highs get more emphasis, but not as much as the bass. I can feel their presence and the treble does introduce some airiness into the overall presentation. However, the amount of treble is far less than sufficient to “neutralize” the thickness from the bass.

The overall sound signature is skewed towards the warmer side.

Connectivity

  • Audio Codec: AAC, SBC, and LDAC
  • Bluetooth Version: Bluetooth V5.2
  • Auto-connect when: Taken out of the case
  • Average drop-outs in an hour: 1 – 2 times
  • Multi-point connection: Yes

The EarFun Free Pro 2 supports AAC and SBC. The latest Bluetooth V5.2 is implemented on Free Pro 2 and they will auto-connect to the last connected device once out of the charging case. The connection stability is great and I only experienced some signal drop-outs in heavy interference regions like crowded trains.

Waterproof

  • IP Rating: IPX5

The Free Pro 2 is certified for IPX5 waterproofness, meaning it can be used for exercising, such as jogging or gym workouts.
