2. How your headphones cancel outside noise?
Active noise-canceling technology relies on the physics called anti-phase, which is a complex concept to visualize, but things will make more sense once it clicks. If two identical waves are placed on top of each other with matching highs and lows, those waves would be called in-phase. In-phase waves add together to create a larger or louder wave. 
 
When two identical waves are out of phase or have opposite high and low points, the waves subtract from each other, leaving a zero-sum. Out of phase waves is how active noise canceling works as the microphone will listen to the ambient noise and create an opposite wave to cancel it out in your ears.

3. What is noise cancelling headphones?
Noise-canceling headphones are Bluetooth headphones that use technology and design to cancel out unwanted noise for the user. Active controlled noise cancelation reduces unwanted ambient sounds with audio technology, which is different from passive headphones that use only soundproofing materials to block outside noise.

4. What is the best noise cancelling headphones?
Many of us have learned the value of a quality pair of noise-canceling headphones from travel, loud neighbors, or blocking out street noise while walking. There are many options for wireless headphones as they have a range of qualities and prices. You do not need to break the bank to enjoy noise-canceling features, but there is something to be said for the professional audio headsets if you feel like splurging.

The JBL LIVE 650TNC are the perfect headphones for long trips and turning out the rest of the world with active noise-canceling and comfortable ear pads. With built-in smart assistants and more ear cup controls like voice calls, weather updates, and music management, you can never miss a beat while keeping your headphones on. For a similar experience with a lower price tag, consider the JBL TUNE 750TNC. 

5. How does Active Noise Cancellation work?
The most common type of noise-canceling is active noise canceling, where a microphone and amp on the headset work to produce the right sound waves to negate ambient noise for the user. The advances in battery size and ability to fit more technology in smaller spaces have let active noise cancellation become the standard option that is no longer only for high-end audio professionals.
