TrueWireless Mirroring Technology

Regardless of whether you are using a smartphone or a computer, iPhone or Android, the left and right earphones will be connected to the sender simultaneously. TrueWireless Mirroring technology: Whether you are using a smartphone, computer, iPhone or Android, the left and right earphones will be connected to the sender at the same time, so that communication is less disrupted and the battery is not depleted unevenly.

 

60ms low latency mode

When the low latency mode is turned on, the latency can be reduced to as low as 60ms. When playing games or watching videos, the audio can be played back with less delay than normal playback, providing a more immersive experience.

 

However, it is recommended to turn off the low latency mode when listening to music due to the shorter communication distance.

 

cVc8.0 Noise Cancelling Technology

Provides very clear voice quality by reducing echoes and noise wherever you are, allowing for more natural two-way conversations.

 

Up to 30 hours of playback

Up to 30 hours of playback is possible with the use of a charging case. The earphones can be used for up to 7 hours on a single full charge. Convenient wireless charging is supported.

 

IPX7 waterproof and sweatproof

EarFun's proprietary SweatShield technology thoroughly prevents erosion from sweat and water. Commercial waterproof earbuds with nano-coating technology tend to get corroded by sweat after months of use and lose their waterproof performance.

Connection quality

I tested it by connecting it to a Cayin N6II/E02 with AAC. The quality of the connection is excellent for the price range. I haven't been in crowded places, so I don't know, but it's stable in the home. Distance tolerance is excellent, and the connection is seamless and intact even at a distance of about 5 meters. The communication is not interrupted even when interrupted by a barrier, and the music plays fine afterwards, with no interruptions.

 

There may be a small amount of white noise, but most people probably won't notice it.

Sound quality description

EarFun Free 2 has a V-shaped sound with massive low frequencies and glossy, flashy mids and highs. You can enjoy a powerful and energetic sound that is both massive and glaring, and the overall sound is in the tradition of the Free series, which emphasizes low-frequency weight and mid-high frequency clarity.

 

The following review was tested on a FiiO M15 with an aptX connection.

Sound quality general comment
  • Original sound fidelity: A
  • Recommendation: A-
  • Personal preference: A

 

The EarFun Free 2 is definitely part of the Free series, with its traditional emphasis on deep lows and lustrous mids and highs, giving it a slightly more analytical, monitor-like sound with an emphasis on overall balance.

 

Personally, I don't dislike the sound because it is crisp, structured, and easy to understand the framework of music, but I am concerned that the mid-high frequencies are a little too prominent. It's a little too loud at times. Consonants also tend to be too aggressive.

 

Sound quality features
Pros
  • Deep low frequencies
  • Glossy and gorgeous mid and high frequencies
  • Constructive
  • Excellent contrast
  • Analytical

 

Cons
  • Spiky consonants
  • Thin midrange
  • Too prominent mids and highs

 

General comment

EarFun Free 2 is a completely wireless earphone with a V-shaped sound that offers deep bass and glossy mids and highs. I personally enjoy listening to rock music with these, as they let me hear deep bass, heavy drum kicks, crisp snares, and edgy guitars. The communication quality is also good, and it supports wireless charging and low-latency gaming mode, making it a product with high overall performance.
