Ingress protection ratings refer to the rank of protection given by a casing, against dust and water. In the format of IPXX, 'X' represents a number The first value means protection against solids say dust, while the second refers to protection against liquids (sweat).
Having a value of IPX4, the Bose QuietComfort 2's rating is read as, the first value 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. 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,
they both have the same rating against liquids
Bose QuietComfort 2 have a weight of 12.5g . We prefer a lower weight best for the reason that lighter devices are more comfortable to transport.
The Sony WF 1000XM4, at 7.1g
weigh less than the Bose QuietComfort 2 with a difference -5.4g
For a device to be true wireless it must have no wires linking any part of the device together, Bose QuietComfort 2 are true wireless for this case since they don't have wires. This is a major difference as some wireless earbuds have cables connecting the 2 earbuds .

The Sony WF 1000XM4 also have stereo speakers
Active noise cancellation uses advanced kind of tech to actively counter noise. How it works, it listens to the sound pattern of incoming noise and inverts the soundwaves to counter it. In simple terms, it's like taking +1 (sound from your surrounding) then adding -1 (inverted noise) to make 0 resulting in a reduced level of noise.
The Bose QuietComfort 2 have ANC enabling you to listen at lower volume levels, good for your ears as you don't have to crank up the earbuds volume to overcome background sounds. The Sony WF 1000XM4 too have ANC making both earbuds ideal for flights and rush hour travels.

The Bose QuietComfort 2 have a unit size of 9.3mm in diameter, bigger drivers are more powerful, therefor producing better bass. A driver unit is basically a mini speaker that produces sound in the earbuds, the unit size corellates with the sound made by the earbuds.
Sony WF 1000XM4 driver unit is 6mm in diameter,
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 yes, larger drivers can generate louder sound, but this does not mean that they produce better quality sound. The Bose QuietComfort 2's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device produces low recognizable frequencies and if it alters the signal while at it.
Sony WF 1000XM4's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
Bose QuietComfort 2's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio device generates high recognizable frequencies and if it adjustments to the signal on its way through. Sony WF 1000XM4's highest frequency is at 40,000Hz, this implies that
Sony WF 1000XM4 generate 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. A device's battery life is given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often.
Sony WF 1000XM4's battery life is
more than that of Bose QuietComfort 2 by 2 hours
. Each 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 have shorter listening time. This is given by the manufacturer, and the Bose QuietComfort 2's case has a full charge of 18 hours.
A charging case with a longer battery life enables 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. It is highly adivsable to charge fully the battery before using the earbuds for the first time.
Sony WF 1000XM4 takes 1.5 hours to fully charge the battery,
less than that of Bose QuietComfort 2 by 0.5 hours
