Has Active Noise Cancellation (Anc)
Sony WH XB910N
✓
Creative Zen Hybrid 2 ✓
Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it listens to the sound pattern outside and inside the earbud 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 0 resulting in a reduced level of noise.
Creative Zen Hybrid 2 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

✓
Creative Zen Hybrid 2 ✓
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 Creative Zen Hybrid 2 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
Sony WH XB910N
7Hz
Creative Zen Hybrid 2 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. Creative Zen Hybrid 2'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
Creative Zen Hybrid 2 got a juicier bass than the Sony WH XB910N
Highest Frequency
Sony WH XB910N
25,000Hz
Creative Zen Hybrid 2 20,000Hz
High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it makes any changes to the signal on the way through. Creative Zen Hybrid 2'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 means that
Sony WH XB910N got a clearer and crispier treble than the Creative Zen Hybrid 2
Sound Pressure Level
Sony WH XB910N
96dB/mW
Creative Zen Hybrid 2 ✗
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 XB910N's measurement is 96dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Driver Unit Size
Sony WH XB910N
40mm
Creative Zen Hybrid 2 40mm
The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Creative Zen Hybrid 2 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 Creative Zen Hybrid 2 similar in how loud their sound gets
, 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 yeah, larger drivers are capable of generating louder sound, but this does not mean that they deliver better sound.
Impedance
Sony WH XB910N
48Ohms
Creative Zen Hybrid 2 ✗
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. Sony WH XB910N's impedance is 48Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Has A Neodymium Magnet
Sony WH XB910N
✓
Creative Zen Hybrid 2 ✓
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 Creative Zen Hybrid 2 have this type of magnet.
Sony WH XB910N have it too, devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. It is also known that they have more bass and clear high notes.
