Sony WF-1000XM4 vs Soundcore Liberty Air 2 - Where are the differences?
Where are the differences?
The Sony WF-1000XM4 true wireless headphones differ a few points from the Soundcore Liberty Air 2. Let's go into the differences in detail.
What about the battery life?
A crucial point for headphones without cables is always the battery life. Here, many headphones differ and the capacity grows from year to year. The battery life of the Soundcore Liberty Air 2 is longer here with 7,0 hours. With a lower battery life of up to 6,0 hours, the Sony WF-1000XM4 scores worse at this point.
An additional battery in the case has become popular for true wireless headphones. Thus, the headphones can be conveniently charged on the go and have a longer battery life overall. The Soundcore Liberty Air 2* is in front here. The headphones offer a battery life of up to 28,0 hours with a case. The battery life of the Sony WF-1000XM4 is up to 24,0 hours.
How to charge the headphones?
Both devices use the same technology for the charging connection. Both are charged via USB-C.
The charging time of the devices:
- Sony WF-1000XM4*: 5,0 minutes charge time for 1,0 hours battery life
- Soundcore Liberty Air 2*: 10,0 minutes charge time for 2,0 hours battery life
Many headphones offer some form of noise cancellation. However, it is not true Active Noise Cancelling (ANC for short) in all of them. In this comparison, only the Sony WF-1000XM4 offers ANC.
Let's talk about the microphones, which also have an impact on voice quality and noise suppression. Most headphones no longer rely on just one microphone, but on several. Unlike the Sony WF-1000XM4, the Soundcore Liberty Air 2* with 4 pieces per side offers more. The Sony WF-1000XM4 has 2 microphones built in per earpiece.
Of course, both TWS headphones work over Bluetooth. However, the version is different. The Sony WF-1000XM4 uses a newer standard with the version 5.2 than the Soundcore Liberty Air 2 with the Bluetooth version 5.0. Newer Bluetooth versions offer more stability in the connection and also a better range.
Can the ear studs be used separately?
The right earpiece can also be used independently of the left earpiece in almost every true wireless headphone. This is also the case with both devices from this comparison. Rarely, the left headphone can be used separately, because they work in dependency of the right ear plug. Mostly the right headphone is the so called master. In this case both the Sony WF-1000XM4 and the Soundcore Liberty Air 2 can use this feature.
Are there interchangeable attachments?
For better wearing comfort, both headphones from the comparison offer changeable attachments. However, the number of attachments is different. The Sony WF-1000XM4 offers 3 pieces. With the Soundcore Liberty Air 2 you get 5 at the number.
Are the headphones waterproof?
Both headphones from the comparison have IP certification. The Sony WF-1000XM4 is certified with IPX4. With the Soundcore Liberty Air 2 you get an IPX5 certification. However, an IP certification does not directly mean waterproof. Depending on the certification, the headphones are only water- or sweat-resistant. However, a higher number in the certification is generally better. With Bluetooth headphones, there is also the problem that Bluetooth is disturbed by water. Thus, the use when swimming is only possible with special headphones.
