Ingress protection ratings is the rank of protection given by a casing, against dust and water. In the format of IPXX, 'X' represents a number The first value of the IP rating means protection against solids such as dust, while the second refers to resistance against liquids (water).
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 the second number of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. Compared to the Bose QuietComfort 2, Sony WF 1000XM4 have a rating of IPX4 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,

Both Sony WF 1000XM4 and Bose QuietComfort 2 have stereo speakers
ANC utilises advanced kind of tech to actively cancel noise. How it works, it studies the sound pattern of incoming noise and after generates a mirror signal to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) and producing -1 (inverted noise) giving 0 therefore "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 have to crank up the device volume to overcome background noise. Sony WF 1000XM4 too have Active Noise Cancellation making both earbuds ideal for plane rides and rush hour travels.

which means that they have a smaller driver unit than that of Bose QuietComfort 2 by 3.3mm
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not imply that they deliver better quality sound.
The Bose QuietComfort 2's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component produces low frequencies that can be heard, and if it makes any changes to the signal while at it. Sony WF 1000XM4's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
The Bose QuietComfort 2's highest frequency is at 20,000Hz, high-frequency response measures if and how well a particular audio device makes high human frequencies and if it changes to the signal on its way through. Sony WF 1000XM4's highest frequency is at 40,000Hz, this implies that
Sony WF 1000XM4 can produce a clearer and crispier treble than the Bose QuietComfort 2
Bose QuietComfort 2's battery life is 6 hours, these last longer than 5 hours of listening which is considered average for a single charge.

more than that of Bose QuietComfort 2 by 2 hours
. Every time you recharge your device, they get a little less listening time. The effect is barely noticeable at first, but over a few years, your wireless earbuds will no longer play for long like they used to.
This is given by the manufacturer, and Bose QuietComfort 2's case has a charge of 18 hours. A charging case with more battery hours allows you to recharge your earbuds on the go multiple times before recharging the case itself. Sony WF 1000XM4's charging case has a battery life of 16 hours,
less than that of Bose QuietComfort 2 by 2 hours
It requires 2 hours to fully charge the Bose QuietComfort 2's battery.
