Has Active Noise Cancellation (Anc)
JLab Audio Play
✗
Bose QuietComfort 45 ✓
Active noise cancellation uses more advanced technology to actively counter noise. 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 hence "diluting" the noise.
Bose QuietComfort 45 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
JLab Audio Play
✗
Bose QuietComfort 45 ✓
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 Bose QuietComfort 45 sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.
Lowest Frequency
JLab Audio Play
20Hz
Bose QuietComfort 45 ✗
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 on the way through. JLab Audio Play's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
Highest Frequency
JLab Audio Play
20000Hz
Bose QuietComfort 45 ✗
High frequency response measures if and how well a particular audio component reproduces high audible frequencies and if it makes any changes to the signal while at it. JLab Audio Play's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Sound Pressure Level
JLab Audio Play
110dB/mW
Bose QuietComfort 45 ✗
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, JLab Audio Play's measurement is 110dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Driver Unit Size
JLab Audio Play
40mm
Bose QuietComfort 45 40mm
The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. JLab Audio Play driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.
Bose QuietComfort 45 driver unit is 40mm in diameter,
making both Bose QuietComfort 45, and JLab Audio Play 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 yes, larger drivers can generate louder sound, but this does not mean that they produce better sound.
Impedance
JLab Audio Play
32Ohms
Bose QuietComfort 45 ✗
Defined as 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 conductor is measured in ohms. JLab Audio Play's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Has A Neodymium Magnet
JLab Audio Play
✓
Bose QuietComfort 45 ✗
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 JLab Audio Play have this type of magnet.
