Has Active Noise Cancellation (Anc)
JBL Live 460NC
✓
Sony WH XB910N ✓
Active noise cancellation uses more advanced technology to actively counter noise. How it works, it detects and analyzes the sound pattern of incoming noise and then inverts the soundwaves 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 0 resulting in a reduced level of noise.
JBL Live 460NC 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.
Sony WH XB910N too have active noise cancellation making both devices ideal for plane rides and morning commutes. Each may work with different noise cancellation modes, pick the setting, mode, or noise cancellation type that you prefer for commute or that enhances your relaxation time.
Has Passive Noise Reduction

Sony WH XB910N ✓
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 JBL Live 460NC 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 XB910N isolates you from ambient noise instead of actively using technology to cancel it out.
Lowest Frequency
JBL Live 460NC
20Hz
Sony WH XB910N 7Hz
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 on the way through. JBL Live 460NC's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
Sony WH XB910N's lowest frequency is at 7Hz, this implies that
JBL Live 460NC got a juicier bass than the Sony WH XB910N
Highest Frequency
JBL Live 460NC
20,000Hz
Sony WH XB910N 25,000Hz
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. JBL Live 460NC's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Sony WH XB910N's highest frequency is at 25,000Hz, this implies that
Sony WH XB910N got a clearer and crispier treble than the JBL Live 460NC
Sound Pressure Level
JBL Live 460NC
96dB/mW
Sony WH XB910N 96dB/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, JBL Live 460NC's measurement is 96dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Sony WH XB910N's sound pressure level measurement is 96dB/mW.
Driver Unit Size
JBL Live 460NC
40mm
Sony WH XB910N 40mm
The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. JBL Live 460NC driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.
Sony WH XB910N driver unit is 40mm in diameter,
making both Sony WH XB910N, and JBL Live 460NC 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 it's true that, larger drivers can generate louder sound, but this does not mean that they produce better sound.
Impedance
JBL Live 460NC
32Ohms
Sony WH XB910N 48Ohms
Defined as the device's resistance to the electromagnetic current, as electricity flows through a conductor, it faces electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. JBL Live 460NC's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Sony WH XB910N's impedance is 48Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
Has A Neodymium Magnet
JBL Live 460NC
✗
Sony WH XB910N ✓
Neodymium magnets if used in audio devices produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The Sony WH XB910N have this type of magnet.
