IP ratings refer to the level of protection offered by an enclosure, against dust and water. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids say dust, followed by the one that refers to protection against liquids (sweat).

Having a value of IPX4, the JBL Tune Flex's rating for solids indicates that no data available to specify a protection rating, and the second value 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 JBL Tune Flex, 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 JBL Tune Flex have a weight of 9.6g . We prefer a lower weight better because lighter devices are more comfortable to carry.

The Sennheiser Momentum 3, at 10.6g are heavier than the JBL Tune Flex with a difference of 1g For a device to be true wireless it must have no wires linking any part of the device together, JBL Tune Flex are true wireless for this case since they don't have cables. This is a key difference since wireless earbuds have cables connecting the two earbuds together. Sennheiser Momentum 3 also is true wireless because it doesn't have cables connecting the two earbuds . JBL Tune Flex have sweat resistance Sennheiser Momentum 3's resistance to sweat makes both devices fit for use during long-distance running, marathons, training in workout bodysuits, etc JBL Tune Flex have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience.

Both Sennheiser Momentum 3 and JBL Tune Flex have stereo speakers ANC uses more advanced kind of tech to reduce ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. Simply put, it's like taking +1 (noise) then adding -1 (inverted noise) to make 0 resulting in a reduced level of noise.



The JBL Tune Flex have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears since you don't need to crank up the device volume to overcome background sounds. Sennheiser Momentum 3 too have Active Noise Cancellation which makes both devices ideal for flights and morning commutes. The JBL Tune Flex and Sennheiser Momentum 3 work with different noise cancellation modes, pick the noise cancellation type that suits your commute or that suites your chill time.

The JBL Tune Flex sit well in place, creating an acoustic covering that reduces your environment sounds well as preventing the device voice audio from leaking out . Both Sennheiser Momentum 3, and JBL Tune Flex have passive noise reduction which implies that they tone down ambient noise without using technology to cancel it out. JBL Tune Flex driver unit is 12mm 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 corellates with the loudness of the device.

Sennheiser Momentum 3 driver unit is 7mm in diameter, which means that they have a smaller driver unit than that of JBL Tune Flex by 5mm , 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 indicate that they produce better quality sound. JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component 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 produce a juicier bass than the JBL Tune Flex JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response tells how well an audio device makes high human frequencies and if it changes to the signal on its way through. Sennheiser Momentum 3's highest frequency is at 21,000Hz, this means that Sennheiser Momentum 3 can generate a clearer and crispier treble than the JBL Tune Flex SPL, is the level of pressure of sound, in decibels, dB, JBL Tune Flex's measurement is 108dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

Sennheiser Momentum 3's sound pressure level measurement is 107dB/mW. How loud something is can be considered differently by separate persons, so we need to have the means to get an objective measurement of sound level expressed in numerical terms. JBL Tune Flex's battery life is 8 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 more battery hours, you get to use it for longer and have to charge the device less often. Sennheiser Momentum 3's battery life is less than that of JBL Tune Flex by 1 hours . Every time you recharge your earbuds, they get a little less listening time. The effect is barely 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 JBL Tune Flex's case is said to have a charge of 24 hours. A charging case with more battery hours allows you to recharge your earbuds on the go many times before recharging the case itself. Sennheiser Momentum 3's charging case has a battery life of 21 hours, less than that of JBL Tune Flex by 3 hours It requires 2 hours to fully charge the JBL Tune Flex's battery.

It is highly adivsable to fully charge the battery before using the earbuds when they have been in storage for long periods. Sennheiser Momentum 3 takes 1.5 hours to fully charge the battery, less than that of JBL Tune Flex by 0.5 hours The JBL Tune Flex have a battery level indicator, an indicator notifies you when the earbuds has a low battery. The battery indicator lights display the charging status of your device and case.

Sennheiser Momentum 3 too have a battery level indicator, charging indicators enable you to tell the charging state of your earbuds, whether fully charged, or the battery is running low. JBL Tune Flex support USB TYPE-C, a standard connector for transmitting both data and power through 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. JBL Tune Flex have Bluetooth version of 5.2, Bluetooth is a wireless technology standard that allows data movement between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Sennheiser Momentum 3 has a Bluetooth version of 5.2, equal to that of the JBL Tune Flex . Newer versions provide faster data transfers.

JBL Tune Flex have a 10meters distance to connect via Bluetooth. Sennheiser Momentum 3 have a maximum range of 10meters, equal to that of the JBL Tune Flex JBL Tune Flex 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 a similar bit rate.

Since its the highest quality codec that any Bluetooth-supporting Apple product supports, the JBL Tune Flex will work well with your iPad. If you are planning 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 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. JBL Tune Flex have 4 microphones.

The Sennheiser Momentum 3 microphones are 6, more than that of JBL Tune Flex by 2 . More microphones result in better sound quality and help the device to filter out noise. The JBL Tune Flex have a noise-canceling type of microphone, these microphones are intended to reduce noise from the earbuds' sound. The Sennheiser Momentum 3 too use a noise-canceling microphone.

This is useful in noisy areas. The JBL Tune Flex microphone sensitivity is measured at -38dBV/Pa. The size of the analog or digital output signal from the microphone with its input stimulus is a measure of its sensitivity.

It's the 'loudness' of the voice that the microphone can pick up. The JBL Tune Flex support ambient sound mode, which uses microphones to pass through ambient sound so that they can still be heard even when wearing the earbuds The Sennheiser Momentum 3 support ambient sound mode as well, helpful when you want to listen to music but also be aware of what’s happening around you, say you’re having a run but would still want to hear traffic. When misplaced in a room, or can't be found in your bag, JBL Tune Flex support the find earbuds feature.

JBL Tune Flex support fast charging. Most often, technologies like Qualcomm’s Quick Charge, are used to lower the amount of time it takes to fully charge a device. The Sennheiser Momentum 3 too support fast charging.

It's very similar to regular charging, just that the battery fills up much faster. Say, with Quick Charge 3.0, the battery can be charged to 50% in 30 minutes. JBL Tune Flex support multipoint of 2 connections, the multipoint feature allows you connect to more than one Bluetooth device and switch between them.

For example, you can easily switch calls from one device to another without having to manually disconnect and reconnect. The JBL Tune Flex have a mute function, they support the feature to mute/unmute a conversation directly from the earbuds. The Sennheiser Momentum 3 also support the mute function.

It means that you can turn off the earbuds' microphone, but you can still hear the other party's voice. With the JBL Tune Flex, so you can access the volume control, pause, play, mute, etc whichever functions are supported on the device. The Sennheiser Momentum 3 also have a control panel on them.

The JBL Tune Flex support voice prompts. Automatically receive information via audio messages, say if there is a problem with the connection. The Sennheiser Momentum 3 too have voice prompts meaning the earbuds notifies you if the battery is running low, and you need to recharge them.

The JBL Tune Flex come with a special pouch. Carrying earphones openly, or placing them in your bag without a casing can easily put them at risk of getting damaged. Sennheiser Momentum 3 too have a travel bag included, which is useful for safe transportation.
