Has Active Noise Cancellation (Anc)

Edifier W820BT ✗
Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it listens to 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.
Focal Utopia Series 2022 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

Edifier W820BT ✓
Passive Noise Cancellation uses well-designed ear cups to seal out environment noise. This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out.
The Edifier W820BT sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.
Lowest Frequency
Focal Utopia Series 2022
5hz
Edifier W820BT 20hz
Low-frequency response measures if and how well a particular audio device reproduces low audible frequencies and if it makes any changes to the signal while at it. Edifier W820BT's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
Focal Utopia Series 2022's lowest frequency is at 5Hz, this implies that
Edifier W820BT got a juicier bass than the Focal Utopia Series 2022
Highest Frequency
Focal Utopia Series 2022
50,000hz
Edifier W820BT 20,000hz
High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it changes to the signal while at it. Edifier W820BT's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Focal Utopia Series 2022's highest frequency is at 50,000Hz, this means that
Focal Utopia Series 2022 got a clearer and crispier treble than the Edifier W820BT
Sound Pressure Level
Focal Utopia Series 2022
104db/mw
Edifier W820BT 100db/mw
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 the means to get 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, Edifier W820BT's measurement is 100dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Focal Utopia Series 2022's sound pressure level measurement is 104dB/mW.
Driver Unit Size
Focal Utopia Series 2022
40mm
Edifier W820BT 40mm
The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Edifier W820BT driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.
Focal Utopia Series 2022 driver unit is 40mm in diameter,
making both devices similar in how loud their sound gets
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty reproducing high frequencies so yeah, larger drivers can generate louder sound, but this does not mean that they produce better sound.
Impedance
Focal Utopia Series 2022
80ohms
Edifier W820BT 32ohms
Impedance is the device's resistance to the electromagnetic current, as electricity flows through a wire, it experiences electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms. Edifier W820BT's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Focal Utopia Series 2022's impedance is 80Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
Has A Neodymium Magnet
Focal Utopia Series 2022
✗
Edifier W820BT ✓
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 Edifier W820BT have this type of magnet.
