Sound Quality

Has Active Noise Cancellation (Anc)

JBL Live 770NC

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 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.

JBL Live 770NC 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

JBL Live 770NC

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 770NC sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.

Lowest Frequency

Low-frequency response measures if and how well an audio device reproduces low audible frequencies and if it makes any changes to the signal on the way through. JBL Live 770NC's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.

Highest Frequency

JBL Live 770NC 20,000hz

High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it changes to the signal while at it. JBL Live 770NC's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.
