Jbl Tune Flex Review

Ingress protection ratings is the rank of protection offered by an enclosure, against solids and water. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids such as dust, followed by the one that refers to protection against liquids (sweat).

Scoring 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. The JBL Tune Flex have a weight of 9.6g . We prefer a lower weight best because lighter devices are more comfortable to carry.

True wireless devices have no cables linking any part of the device together, JBL Tune Flex are true wireless for this case since they have no cables. This is an important distinction as some wireless earbuds have cables linking the 2 earbuds . JBL Tune Flex have sweat resistance JBL Tune Flex have stereo speakers, what this means is that JBL Tune Flex's speakers deliver sound from separate channels on both left and right sides, this creates a richer sound and a better listening experience. Active noise cancellation makes use of more advanced kind of tech to actively counter noise.

How it works, it studies the sound pattern of incoming noise and then generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) then adding -1 (inverted noise) to make zero thus "diluting" the noise.

JBL Tune Flex have ANC allowing you to listen at lower volume levels, causing less ear fatigue since you don't have to crank up the device volume to outcompete background sounds.

JBL Tune Flex stay tightly in place, this creates a sound covering that tones down background noise while preventing the device sound from leaking out . JBL Tune Flex have a unit size of 12mm in diameter, bigger drivers are more powerful, therefor producing better bass. A driver unit is the component that produces sound in the device, its size dictates the loudness of the earbuds. The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component produces low frequencies that can be heard, and if it makes any changes to the signal on its way through.

The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response tells how well a particular audio component makes high recognizable frequencies and if it makes any changes to the signal on its way through. 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.

The 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 given by the manufacturer, and with more battery hours, you get to use it for longer and requires fewer chargings.

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 MacBook.

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. JBL Tune Flex have 4 microphones. The JBL Tune Flex use a noise-canceling microphone, these microphones are intended to reduce background sounds from the desired sound.

JBL Tune Flex microphone sensitivity is measured at -38dBV/Pa. The vastness of the analog or digital output signal from the microphone with its input stimulus is a calculation of its sensitivity. It's the 'loudness' of the voice that the earbud microphone can recognize.

JBL Tune Flex support ambient sound mode, which uses microphones to channel ambient noises so that they can still be heard even while wearing the earbuds If misplaced in a room, or can't easily find them in your bag, JBL Tune Flex support the find earbuds feature.
