Has Active Noise Cancellation (Anc)
JBL Tune 750BTNC
✓
Skullcandy Hesh Evo Wireless ✗
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 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 Tune 750BTNC 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

Skullcandy Hesh Evo Wireless ✓
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 Skullcandy Hesh Evo Wireless 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 JBL Tune 750BTNC isolates you from ambient noise instead of actively using technology to cancel it out.
Lowest Frequency
JBL Tune 750BTNC
20Hz
Skullcandy Hesh Evo Wireless 20Hz
Low-frequency response measures if and how well an audio component reproduces low audible frequencies and if it makes any changes to the signal while at it. Skullcandy Hesh Evo Wireless's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
JBL Tune 750BTNC's lowest frequency is at 20Hz, this implies that
both devices produce equal bass
Highest Frequency
JBL Tune 750BTNC
20,000Hz
Skullcandy Hesh Evo Wireless 20,000Hz
High frequency response measures if and how well an audio component reproduces high audible frequencies and if it makes any changes to the signal on the way through. Skullcandy Hesh Evo Wireless's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.
JBL Tune 750BTNC's highest frequency is at 20,000Hz, this implies that
both devices produce equal treble
Sound Pressure Level
JBL Tune 750BTNC
100dB/mW
Skullcandy Hesh Evo Wireless 91.3dB/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, Skullcandy Hesh Evo Wireless's measurement is 91.3dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
JBL Tune 750BTNC's sound pressure level measurement is 100dB/mW.
Driver Unit Size
JBL Tune 750BTNC
40mm
Skullcandy Hesh Evo Wireless 40mm
The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Skullcandy Hesh Evo Wireless driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.
JBL Tune 750BTNC driver unit is 40mm in diameter,
making both JBL Tune 750BTNC, and Skullcandy Hesh Evo Wireless 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 yes, larger drivers can generate louder sound, but this does not mean that they produce better sound.
Impedance
JBL Tune 750BTNC
32Ohms
Skullcandy Hesh Evo Wireless 32Ohms
Defined as the device's resistance to the electromagnetic current, as electricity flows through a conductor, it experiences electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms. Skullcandy Hesh Evo Wireless's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
JBL Tune 750BTNC's impedance is 32Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
