Momentum True Wireless 4 Review

IP ratings refer to the rating of protection given by an enclosure, against dust and liquids. The letters 'IP' are followed by two values The first value of the IP rating means protection against solids say dust, while the second refers to resistance against liquids (water).

Scoring IP54, the Momentum True Wireless 4's rating is read as, the first value of 5 denotes that ingress of dust is not totally prevented but dust does not enter in harmful quantities to interfere with the correct operation or impair safety, 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. The Momentum True Wireless 4 have a weight of 12.4g . We consider a lower weight better for the reason that lighter devices are more comfortable to carry.

For a device to be true wireless it should have no wires linking any part of the device together, Momentum True Wireless 4 are true wireless for this case since they don't have cables. This is a major difference since wireless earbuds have wires linking the 2 earbuds . Momentum True Wireless 4 have sweat resistance The Momentum True Wireless 4 are both dustproof and water-resistant. Momentum True Wireless 4 have stereo speakers, what this means is that Momentum True Wireless 4's speakers deliver sound from separate channels on both left and right sides, this creates a richer sound and a better listening experience.

ANC utilises advanced technology to reduce ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and then inverts the soundwaves to counter it. Simply put, it's like taking +1 (noise) then adding -1 (inverted noise) to make 0 thus "diluting" the noise.

The Momentum True Wireless 4 have Active Noise Cancellation enabling you to listen at lower volume levels, causing less ear fatigue since you don't have to crank up the device volume to overcome background sounds. The Momentum True Wireless 4 stay tightly in place, creating an acoustic covering that reduces your environment sounds well as preventing the earbuds voice audio from leaking out . Momentum True Wireless 4 driver unit is 7mm in diameter, the bigger the unit the more powerful, and can produce better bass. The driver unit is the component that makes sound in the device, the unit size dictates the sound produced by the earbuds.

The Momentum True Wireless 4's lowest frequency is at 5Hz, low-frequency response measures if and how well a particular audio component produces low frequencies that can be heard, and if it makes any changes to the signal while at it. The Momentum True Wireless 4's highest frequency is at 21,000Hz, high-frequency response tells how well a particular audio device generates high recognizable frequencies and if it makes any adjustments to the signal on its way through. SPL, is the level of pressure of sound, in decibels, dB, Momentum True Wireless 4's measurement is 107dB/mW.

Devices with a higher sound pressure level are generally louder when supplied with any given audio source. Momentum True Wireless 4's battery life is 7.5 hours, these last longer than 5 hours of listening which is considered average before recharge. A device's battery life is given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chargings.

The battery life of the charging case is given by the vendor, and Momentum True Wireless 4's case is said to have a full charge of 22.5 hours. A charging case with more battery hours allows you to recharge your earbuds on the go multiple times before recharging the case itself. It requires 1.5 hours to fully charge the Momentum True Wireless 4's battery.

It is recommended to charge fully the battery before using the earbuds when they have been in storage for long periods. The Momentum True Wireless 4, the device supports wireless charging. To charge the device, you just put down on a supported charging pad.

Momentum True Wireless 4 have Bluetooth version of 5.4, Bluetooth is a wireless technology standard that allows data movement between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. The Momentum True Wireless 4 have a 10meters distance to connect via Bluetooth. Momentum True Wireless 4 support AAC, a codec that is used for Bluetooth audio.

It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it provides better results than other codecs at a similar bit rate.

Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Momentum True Wireless 4 will work well with your iPad.

If you intend 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. Momentum True Wireless 4 support APTX Adaptive, an audio codec for Bluetooth devices that are developed by Qualcomm. It has a variable bit rate (between 279kbps and 420kbps). Momentum True Wireless 4 have 6 microphones.

Momentum True Wireless 4 have a noise-canceling type of microphone, these microphones are intended to reduce background sounds from the desired sound. The Momentum True Wireless 4's highest mic frequency is 10,000Hz, high frequencies are best for picking up treble. The highest mic frequency of a microphone is defined as its upper limiting frequency.

The Momentum True Wireless 4's lowest mic frequency is 100Hz, low frequencies are better for recording bass. The lowest mic frequency of a microphone is defined as its lower limiting frequency. Momentum True Wireless 4 support ambient sound mode, which uses microphones to pass through ambient noises to still be heard even while wearing them The Momentum True Wireless 4 support fast charging.

Commonly, technologies like MediaTek’s Pump Express, are used to reduce the time it takes to fully charge a device. The Momentum True Wireless 4 have a 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 manually disconnect and reconnect.

Momentum True Wireless 4 have a mute function, they have the feature to mute/unmute a conversation directly from the earbuds. The Momentum True Wireless 4, so you can easily access the volume control, pause, play, mute, etc whichever functions are supported on the device.
