IP ratings is the rank of protection given by an enclosure, against solids 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 (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. In comparison to the Bose QuietComfort 2, Sennheiser Momentum 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 2 have a weight of 12.5g . We consider a lower weight better because lighter devices are more comfortable to move with.
Sennheiser Momentum 3, at 10.6g
weigh less than the Bose QuietComfort 2 with a difference -1.9g
For a device to be true wireless it should have no cables connecting any part of the device together, Bose QuietComfort 2 are true wireless for this case since they don't have cables. This is a key distinction since wireless earbuds have wires linking the 2 earbuds together. Sennheiser Momentum 3 also is true wireless because it doesn't have wires connecting the two earbuds .
Bose QuietComfort 2 have wingtips, these are reserved for earbuds for workouts and are usually an optional add-on to each silicone ear tip for a more secure fit.
Bose QuietComfort 2 are resistant to sweat
Sennheiser Momentum 3's resistance to sweat makes both devices good for use while doing sports such as long-distance running, marathons, training in workout bodysuits, etc
Bose QuietComfort 2 have stereo speakers, what this means is that Bose QuietComfort 2's speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience. The Sennheiser Momentum 3 also have stereo speakers
ANC uses more advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern outside and inside the earbud and then generates a mirror signal to counter it.
In simple terms, it's like taking +1 (noise) and adding -1 (counter sound by the device) to make 0 thus "diluting" the noise.
The Bose QuietComfort 2 have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears as you don't need to crank up the earbuds volume to outcompete background noise. The Sennheiser Momentum 3 too have ANC making both earbuds ideal for plane rides and morning travels.
The Bose QuietComfort 2 and Sennheiser Momentum 3 work with different noise cancellation settings, pick the mode that you prefer for travel or that suites your chill time. The Bose QuietComfort 2 sit tightly in place, this creates an acoustic covering that reduces your environment noise well as preventing the earbuds music from leaking out .
Both of these devices have passive noise reduction this means that both limit ambient noise without using ANC to cancel it out. The Bose QuietComfort 2 driver unit is 9.3mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is the component that makes sound in the device, the unit size determines the sound made by the device. Sennheiser Momentum 3 driver unit is 7mm in diameter,
which means that they have a smaller driver unit than that of Bose QuietComfort 2 by 2.3mm
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yeah, 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 measures if and how well an audio device produces low recognizable frequencies and if it makes any changes to the signal while at it. Sennheiser Momentum 3's lowest frequency is at 5Hz, this implies that
Sennheiser Momentum 3 can produce a juicier bass than the Bose QuietComfort 2
Bose QuietComfort 2's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio component produces high audible frequencies and if it adjustments to the signal on its way through. Sennheiser Momentum 3's highest frequency is at 21,000Hz, this means that
Sennheiser Momentum 3 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.
A device's battery life is usually given by the manufacturer, and with longer battery life, you get to use it for longer and have to charge the device less often. Sennheiser Momentum 3's battery life is
more than that of Bose QuietComfort 2 by 1 hours
. Each time you recharge your device, they get a little less listening time. The effect is not noticeable at first, but over time, 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 2's case is said to have a full charge of 18 hours. A charging case with a longer battery life enables you to recharge your earbuds on the go several times before recharging the case itself. Sennheiser Momentum 3's charging case has a battery life of 21 hours,
more than that of Bose QuietComfort 2 by 3 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. Sennheiser Momentum 3 takes 1.5 hours to fully charge the battery,
less than that of Bose QuietComfort 2 by 0.5 hours
The Bose QuietComfort 2 have a battery level indicator, an indicator shows you when the earbuds has a low battery. The battery indicator lights show the charging state of your device and charging case.
Sennheiser Momentum 3 too have a battery level indicator, these allow you to tell the charging state of your earbuds, if charged fully, or the battery is running low. The Bose QuietComfort 2 support USB TYPE-C, an industry-standard connector for transmitting both data and power in a single cable. Sennheiser Momentum 3 too have USB TYPE-C.
This USB-C plug is part and parcel of most current laptops, phones, and tablets. Bose QuietComfort 2 have Bluetooth version of 5.3, Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Sennheiser Momentum 3 has a Bluetooth version of 5.2,
older than that of Bose QuietComfort 2
. Newer versions provide faster data transfers.
Bose QuietComfort 2 have a 10meters distance to connect via Bluetooth. Sennheiser Momentum 3 have a maximum range of 10meters,
equal to that of the Bose QuietComfort 2
Bose QuietComfort 2 support AAC, a codec used for Bluetooth audio. It supports 24-bit audio at 250kbps.
Since it uses psychoacoustic modeling, it can provide better results than other codecs at the same bit rate.
Since its the highest quality codec that any Bluetooth-supporting Apple product supports, the Bose QuietComfort 2 will work fine with your iPad. If you are planning on using these with Android , ensure that they also support aptX HD, LDAC, or LHDC as well.
The Sennheiser Momentum 3 support AAC as well. Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 encoders at the same bit rate. 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).
Sennheiser Momentum 3 support APTX Adaptive as well which implies that both can adjust the bit rate for different scenarios, such as reducing interference from other devices. The Bose QuietComfort 2 have 8 microphones. The Sennheiser Momentum 3 microphones are 6,
less than that of Bose QuietComfort 2 by 2
. More microphones record better sound quality and enable the earbuds to filter out noise.
Bose QuietComfort 2 use a noise-canceling type of microphone, these microphones are made to filter out background sounds from the desired sound. The Sennheiser Momentum 3 too use a noise-canceling microphone. Especially useful in noisy areas.
Bose QuietComfort 2 support ambient sound mode, which uses microphones to pass through ambient sound so that they can still be heard even while wearing the earbuds
The Sennheiser Momentum 3 support ambient sound mode as well, it’s useful when you want to listen to music while being aware of what’s happening around you, for example when you’re having a jog but still want to be able to hear traffic.
