Ingress protection ratings is the level of protection given by an enclosure, against solids and liquids. In the format of IPXX, 'X' represents a number The first value refers to protection against solids say dust, while the second refers to resistance against liquids (sweat).
Scoring IP54, the Momentum True Wireless 4's rating is read as, the first number 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 take in account a lower weight best because lighter devices are easier to carry.
For a device to be true wireless it must have no cables linking any part of the device together, Momentum True Wireless 4 are true wireless for this case since they don't have wires. This is an important distinction as some wireless earbuds have wires linking the pair of earbuds .
Momentum True Wireless 4 have sweat resistance
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 makes use of advanced kind of tech to actively cancel noise. How it works, it studies the sound pattern of incoming noise and inverts the soundwaves to counter it. Simply put, it's like having +1 (noise) and adding -1 (inverted noise) to make 0 thus "diluting" the noise.
Momentum True Wireless 4 have ANC enabling you to listen at lower levels of volume, good for your ears since you don't have to crank up the earbuds volume to outcompete background noise. Momentum True Wireless 4 stay tightly in place, creating a sound covering that reduces your environment sounds and also prevents the device voice audio from leaking out at the same. The Momentum True Wireless 4 have a unit size of 7mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is the component that makes sound in the earbuds, its size corellates with the sound produced by the device. The Momentum True Wireless 4's lowest frequency is at 5Hz, low-frequency response inidcates how well an audio component produces low frequencies that can be heard, and if it alters the signal on its way through. The Momentum True Wireless 4's highest frequency is at 21,000Hz, high-frequency response shows how well a particular audio component makes high recognizable frequencies and if it makes any changes to the signal while at it.
SPL, is the pressure level of sound, measured 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. The 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 usually given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often. 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 enables you to recharge your earbuds on the go several times before having to recharge the case itself.
It takes 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. Momentum True Wireless 4, the device supports wireless charging.
To charge the device, you just put down on a compatible charging pad. The Momentum True Wireless 4 have a battery level indicator, an indicator alerts you when the device has a low battery. The battery indicator lights indicate the charging status of your earbuds and charging case.
Momentum True Wireless 4 support USB TYPE-C, an industry-standard connector for transmitting both data and power in a single cable. The Momentum True Wireless 4 have Bluetooth version of 5.4, Bluetooth is a wireless technology standard that enables data movement between devices placed in range, using short-wavelength, ultra-high frequency radio waves. The Momentum True Wireless 4 have a 10meters distance connecting via Bluetooth.
Momentum True Wireless 4 support AAC, a codec used for Bluetooth audio. It supports 24-bit audio at 250kbps. Since it uses psychoacoustic modeling, it provides better results than other codecs at the same bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Momentum True Wireless 4 will work fine with your iPhone. If you are planning on using these with Android , ensure that they also support aptX HD, LDAC, or LHDC as well. The 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).
The Momentum True Wireless 4 have 6 microphones. Momentum True Wireless 4 use a noise-canceling type of microphone, these microphones are made to filter out noise from the desired sound. The Momentum True Wireless 4's highest mic frequency is 10,000Hz, high frequencies are better for recording treble.
The highest mic frequency of a microphone is defined as its upper limiting frequency. Momentum True Wireless 4's lowest mic frequency is 100Hz, low frequencies are best for picking up bass. The lowest mic frequency of a microphone is defined as its lower limiting frequency.
The Momentum True Wireless 4 support ambient sound mode, which uses microphones to channel ambient sound so that they can still be heard even while wearing the earbuds
Momentum True Wireless 4 support fast charging. Usually, technologies like MediaTek’s Pump Express, are used to lower the amount of time it takes to fully charge the earbuds. 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 support the feature to mute/unmute a conversation directly from the device. With the Momentum True Wireless 4, so you can access the volume control, pause, play, mute, etc whichever functions are supported on the device.
The Momentum True Wireless 4 have a warranty period of 2 Years, the period of time that warrant free repair and adjustment services in case of a malfunction occurring under normal use following instruction manuals. The Momentum True Wireless 4 support voice prompts. With voice prompts, you receive information via audio messages, say if there is a problem with the connection.
The Momentum True Wireless 4 come with a special case. Carrying earbuds openly, or putting them inside your bag without a casing can easily put them at risk of getting damaged.
