Has Active Noise Cancellation (Noise Control)
FiiO FW5
✓
Bowers & Wilkins PI7 ✓
ANC utilises advanced kind of tech to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to counter it. Simply put, it's like having +1 (sound from your surrounding) then producing -1 (inverted noise) to make zero therefore "diluting" the noise.
The FiiO FW5 have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears since you don't need to crank up the device volume to overcome background noise.
The Bowers & Wilkins PI7 too have Active Noise Cancellation making both earbuds ideal for flights and rush hour travels. The FiiO FW5 and Bowers & Wilkins PI7 work with different noise cancellation modes, pick the mode that suits your travel or that suites your chill time.
Has Passive Noise Reduction
FiiO FW5
✓
Bowers & Wilkins PI7 ✓
The FiiO FW5 stay well in place, this creates an acoustic seal that reduces background sounds well as preventing the earbuds music from leaking out at the same.
Both of these devices have passive noise reduction this means that both limit ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
FiiO FW5
10mm
Bowers & Wilkins PI7 9.2mm
The FiiO FW5 have a unit size of 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that produces sound in the device, its size dictates the loudness of the earbuds.
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
which means that they have a smaller driver unit than that of FiiO FW5 by 0.8mm
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
FiiO FW5
20hz
Bowers & Wilkins PI7 10hz
The FiiO FW5's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device generates low frequencies that can be heard, and if it makes any changes to the signal on its way through.
Bowers & Wilkins PI7's lowest frequency is at 10Hz, this means that
Bowers & Wilkins PI7 produce a juicier bass than the FiiO FW5
Highest Frequency
FiiO FW5
20,000hz
Bowers & Wilkins PI7 20,000hz
The FiiO FW5's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component generates high audible frequencies and if it adjustments to the signal on its way through.
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, this implies that
both devices can produce equal treble
Sound Pressure Level
FiiO FW5
108db/mw
Bowers & Wilkins PI7 ✗
SPL, is the pressure level of sound, in decibels, dB, FiiO FW5's measurement is 108dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Has A Neodymium Magnet
FiiO FW5
✓
Bowers & Wilkins PI7 ✗
The FiiO FW5 have neodymium magnets, if used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help generate music at quite a high sound pressure level, with the use of high magnetic flux.
