IP ratings refer to the level of protection offered by an enclosure, against solids 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 protection against liquids (sweat).
Having a value of 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 of liquids that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. Momentum True Wireless 4 have a weight of 12.4g . We consider a lower weight better because lighter devices are easier to carry.
True wireless devices have no cables linking any part of the device together, Momentum True Wireless 4 are true wireless for this matter since they don't have wires. This is a major difference since wireless earbuds have cables linking the pair of earbuds together. 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 utilises advanced kind of tech to actively cancel noise. ANC works when, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it.
In simple terms, it's like having +1 (noise) and producing -1 (counter sound by the device) giving 0 thus "diluting" the noise.
Momentum True Wireless 4 have ANC allowing you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the earbuds volume to outcompete background sounds. The Momentum True Wireless 4 stay tightly in place, this creates an acoustic seal that tones down your environment noise while preventing the earbuds music from leaking out .
The Momentum True Wireless 4 driver unit is 7mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is basically a mini speaker that produces sound in the earbuds, the unit size corellates with the loudness of the device. The Momentum True Wireless 4's lowest frequency is at 5Hz, low-frequency response inidcates how well a particular audio device produces low recognizable frequencies and if it alters the signal while at it. Momentum True Wireless 4's highest frequency is at 21,000Hz, high-frequency response indicates how well an audio device makes high human frequencies and if it makes any changes to the signal while at it.
SPL, is the pressure level 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. The Momentum True Wireless 4's battery life is 7.5 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 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 the Momentum True Wireless 4's case is said to have a full charge of 22.5 hours. A charging case with a longer battery life allows you to recharge your earbuds on the go many times before having to recharge the case itself.
It requires 1.5 hours to fully charge the Momentum True Wireless 4's battery. It is highly adivsable to fully charge the battery before using the earbuds when they have been in storage for extended periods. The Momentum True Wireless 4, the device supports wireless charging.
To charge the earbuds, you just put down on a compatible charging pad. Momentum True Wireless 4 have a battery level indicator, an indicator shows you when the earbuds has a low battery. Its lights show the charging state of your device and case.
The Momentum True Wireless 4 use USB TYPE-C, an industry-standard connector for transmitting both data and power through a single cable. Momentum True Wireless 4 have Bluetooth version of 5.4, Bluetooth is a wireless technology standard that allows 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. Because it uses psychoacoustic modeling, it can provide 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 well with your iPhone. If you intend on using these with Android , 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).
The Momentum True Wireless 4 have 6 microphones. The Momentum True Wireless 4 use a noise-canceling type of microphone, these microphones are intended to filter out background sounds from the desired sound. The Momentum True Wireless 4's highest mic frequency is 10,000Hz, high frequencies are best for recording 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 best for recording 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 pass through ambient noises to still be heard even while wearing the earbuds
Momentum True Wireless 4 support fast charging. Most often, technologies like Qualcomm’s Quick Charge, are used to reduce the time it takes to charge a device. Momentum True Wireless 4 have a multipoint of 2 connections, this feature allows you connect to more than one Bluetooth device and switch between them.
Say, you can switch calls from one device to another without having to manually disconnect and reconnect. The Momentum True Wireless 4 have a mute function, they have the option to mute/unmute a conversation directly from the device. The Momentum True Wireless 4, so you can easily access the volume control, pause, play, mute, etc whichever features are supported on the earbuds.
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. Momentum True Wireless 4 have voice prompts. Automatically receive information through audio messages, say if there is a problem with the connection.
Momentum True Wireless 4 come with their own special pouch. Carrying earphones without a case, or putting them inside your pockets without a cover may easily put them at risk of getting damaged.
