IP ratings is the rank of protection offered by an enclosure, against dust and liquids. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids say dust, while the second refers to resistance against liquids (water).
Scoring IPX4, the Bose QuietComfort Earbuds 2's rating for solids indicates 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 Earbuds 2, Sennheiser Momentum True Wireless 3 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
The Bose QuietComfort Earbuds 2 have a weight of 12.5g . We consider a lower weight better because lighter devices are more comfortable to transport.
Sennheiser Momentum True Wireless 3, at 10.6g
weigh less than the Bose QuietComfort Earbuds 2 with a difference -1.9g
True wireless devices have no cables connecting any part of the device together, Bose QuietComfort Earbuds 2 are true wireless for this case since they have no wires. This is an important distinction as some wireless earbuds have wires connecting the pair of earbuds .

Both Sennheiser Momentum True Wireless 3 and Bose QuietComfort Earbuds 2 have stereo speakers
ANC makes use of advanced technology to actively counter noise. ANC works when, it listens to the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. In simple terms, it's like having +1 (noise) then producing -1 (inverted noise) giving zero resulting in a reduced level of noise.
The Bose QuietComfort Earbuds 2 have ANC enabling you to listen at lower volume levels, good for your ears as you don't need to crank up the device volume to outcompete background sounds.

The Bose QuietComfort Earbuds 2 driver unit is 9.3mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
The driver unit is the component that makes sound in the device, the unit size dictates the sound made by the earbuds. Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter,
which means that they have a smaller driver unit than that of Bose QuietComfort Earbuds 2 by 2.3mm
, many people have a misconception 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 indicate that they produce better quality sound.
Bose QuietComfort Earbuds 2's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component generates low recognizable frequencies and if it alters the signal while at it. Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this implies that
Sennheiser Momentum True Wireless 3 make sound with a juicier bass than the Bose QuietComfort Earbuds 2
Bose QuietComfort Earbuds 2's highest frequency is at 20,000Hz, high-frequency response measures if and how well a particular audio device generates high audible frequencies and if it makes any adjustments to the signal while at it. Sennheiser Momentum True Wireless 3's highest frequency is at 21,000Hz, this implies that
Sennheiser Momentum True Wireless 3 can generate a clearer and crispier treble than the Bose QuietComfort Earbuds 2
The Bose QuietComfort Earbuds 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. Sennheiser Momentum True Wireless 3's battery life is
more than that of Bose QuietComfort Earbuds 2 by 1 hours
. Every time you recharge your earbuds, they get a little less playing 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.
The battery life of the charging case is given by the vendor, and the Bose QuietComfort Earbuds 2's case has a full charge of 18 hours. A charging case with a longer battery life allows you to recharge your earbuds on the go multiple times before recharging the case itself. Sennheiser Momentum True Wireless 3's charging case has a battery life of 21 hours,
more than that of Bose QuietComfort Earbuds 2 by 3 hours
It requires 2 hours to fully charge the Bose QuietComfort Earbuds 2's battery.
