A breakdown of the review per specifications



Sony WH CH520 147g
Huawei Freebuds Studio 260g

The Huawei Freebuds Studio have a weight of 260g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We take in account a lower weight better because lighter devices are more comfortable to move with.

Sony WH CH520, at 147g weigh less than the Huawei Freebuds Studio by -113g

Has A Tangle Free Cable

Sony WH CH520
Huawei Freebuds Studio

Twisted headphone cables can be a great source of annoyance and inconvenience, Sony WH CH520's cable is designed to minimize tangling. Constant twisting of the cables can also lead to microfractures in the copper wires, affecting sound quality, or rendering your headphones defective.

Sweat Resistance

Sony WH CH520
Huawei Freebuds Studio

By sweat resistance we mean that the wireless earbuds are protected in the presence of low-pressure water jets at any angle, this is determined by the IP Rating of the earbuds. Based on the ingress protection rating of the Sony WH CH520 they do have sweat resistance

Has An Over-The-Ear Foam

Sony WH CH520
Huawei Freebuds Studio

Over-ear headphones have larger earpads that fit around your entire ear Huawei Freebuds Studio have a comfortable full-size form with earcups that fully enclose your ears. This design is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors.

Has An On-Ear Foam

Sound Quality

Has Active Noise Cancellation (Anc)

Sony WH CH520
Huawei Freebuds Studio

Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and then generates a mirror signal to cancel it out. In simple terms, it's like taking +1 outside (noise from your surrounding) and adding -1 inside (counter sound within the device) to make zero resulting in a reduced level of noise.

Huawei Freebuds Studio allow you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise.

Has Passive Noise Reduction

Sony WH CH520
Huawei Freebuds Studio

Passive Noise Cancellation uses well-designed ear cups to seal out unwanted noise. This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out. The Huawei Freebuds Studio sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.

Both of these devices have passive noise reduction which means that also the Sony WH CH520 isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

Sony WH CH520 20hz
Huawei Freebuds Studio 4hz

Low-frequency response measures if and how well a particular audio component reproduces low audible frequencies and if it makes any changes to the signal while at it. Huawei Freebuds Studio's lowest frequency is at 4Hz, the lower the low-frequency response, the stronger and juicier the bass.

Sony WH CH520's lowest frequency is at 20Hz, this implies that Sony WH CH520 got a juicier bass than the Huawei Freebuds Studio

Highest Frequency

Sony WH CH520 20,000hz
Huawei Freebuds Studio 48,000hz

High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it changes to the signal on the way through. Huawei Freebuds Studio's highest frequency is at 48,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Sony WH CH520's highest frequency is at 20,000Hz, this means that Huawei Freebuds Studio got a clearer and crispier treble than the Sony WH CH520

Sound Pressure Level

Sony WH CH520 97db/mw
Huawei Freebuds Studio

Sound pressure is the average variation in atmospheric pressure caused by the sound, the sound level .i.e how loud something is can be perceived differently by different people so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.

The sound pressure level, SPL, is the pressure level of a sound, measured in decibels, dB, Sony WH CH520's measurement is 97dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

Driver Unit Size

Sony WH CH520 30mm
Huawei Freebuds Studio 40mm

The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Huawei Freebuds Studio driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.

Sony WH CH520 driver unit is 30mm in diameter, which means that they have a smaller driver unit than that of Huawei Freebuds Studio by 10mm , many people have a misconception that driver units of a bigger size automatically produce better sound quality.

However, large drivers usually have difficulty reproducing high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not mean that they deliver better sound.


Sony WH CH520 35ohms
Huawei Freebuds Studio

Defined as the device's resistance to the electromagnetic current, when electricity flows through a conductor, it experiences electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. Sony WH CH520's impedance is 35Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.

Has A Neodymium Magnet

Sony WH CH520
Huawei Freebuds Studio

Neodymium magnets if used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The Sony WH CH520 have this type of magnet.


Battery Life
