Jbl Tune Flex Vs. Sony Wf 1000Xm4 Review

Scoring IPX4, the JBL Tune Flex's rating for solids indicates that no data available to specify a protection rating, and of liquids 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, Sony WF 1000XM4 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 consider a lower weight best because lighter devices are easier to move with.

The Sony WF 1000XM4, at 7.1g weigh less than the JBL Tune Flex by -2.5g True wireless devices have no cables connecting any part of the device together, JBL Tune Flex are true wireless for this matter since they have no cables.

Both Sony WF 1000XM4 and JBL Tune Flex have stereo speakers Active noise cancellation utilises advanced technology to actively cancel noise. ANC works when, it studies the sound pattern of incoming noise and after inverts the soundwaves to counter it. Simply put, it's like having +1 (noise) and adding -1 (inverted noise) giving zero thus "diluting" the noise.

The JBL Tune Flex have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue as you don't need to crank up the device volume to overcome background noise. The Sony WF 1000XM4 too have ANC which makes both devices ideal for flights and morning commutes. The JBL Tune Flex and Sony WF 1000XM4 operate with different noise cancellation types, pick the noise cancellation type that you prefer for travel or that enhances your relaxation time.

However, large drivers usually have difficulty producing high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not mean that they produce better quality sound.

The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device generates low frequencies that can be heard, and if it makes any changes to the signal on its way through. Sony WF 1000XM4's lowest frequency is at 20Hz, this implies that both devices can produce equal bass 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 adjustments to the signal on its way through. Sony WF 1000XM4's highest frequency is at 40,000Hz, this implies that Sony WF 1000XM4 can produce 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. Sony WF 1000XM4's sound pressure level measurement is 105dB/mW. How loud a device is can be considered differently by separate people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
