IP ratings is the level of protection offered by a casing, against solids and water. The letters 'IP' are followed by two values The first value represents protection against solids such as dust, while the second refers to resistance against liquids (sweat).
Scoring IPX4, the Bose QuietComfort 2's rating is read as, the first number of X denotes that no data available to specify a protection rating, and of liquids that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. Bose QuietComfort 2 have a weight of 12.5g . We take in account a lower weight better for the reason that lighter devices are more comfortable to carry.
True wireless devices have no cables linking any part of the device together, Bose QuietComfort 2 are true wireless for this case since they have no wires. This is a major distinction since wireless earbuds have cables connecting the pair of earbuds .

Active noise cancellation makes use of advanced kind of tech 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. Simply put, it's like taking +1 (noise) then producing -1 (inverted noise) to make 0 thus "diluting" the noise.
Bose QuietComfort 2 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to outcompete background noise. Bose QuietComfort 2 stay tightly in place, this creates an acoustic covering that reduces background noise and also prevents the device music from leaking out .
The Bose QuietComfort 2 have a unit size of 9.3mm in diameter, the bigger the unit the more powerful, and can produce better bass. A driver unit is the component that produces sound in the device, its size determines the sound produced by the device.
The Bose QuietComfort 2's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device generates low frequencies that can be heard, and if it alters the signal on its way through. The Bose QuietComfort 2's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio device produces high human frequencies and if it makes any changes to the signal while at it. Bose QuietComfort 2's battery life is 6 hours, these last longer than 5 hours of listening which is considered average before recharge.
A device's battery life is commonly given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chargings.

Bose QuietComfort 2 have a 10meters distance connecting via Bluetooth. Bose QuietComfort 2 support AAC, a codec that is used for Bluetooth audio. It supports 24-bit audio at 250kbps.
Since it uses psychoacoustic modeling, it provides better results than other codecs at the same bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Bose QuietComfort 2 will work fine with your iPhone. If you intend on using these with Android you need to pay even closer attention to codec support for if they only have AAC they won't provide the best audio quality possible, ensure that they also support aptX HD, LDAC, or LHDC as well.
The Bose QuietComfort 2 support APTX Adaptive, an audio codec for Bluetooth devices that are developed by Qualcomm. It has a variable bit rate (between 279kbps and 420kbps).
