Jbl Tune Flex Review

IP ratings is the rank of protection given by an enclosure, against dust and liquids. The letters 'IP' are followed by two values The first value refers to protection against solids say dust, followed by the one that refers to resistance against liquids (water).

Scoring IPX4, the JBL Tune Flex's rating is read as, the first number of X denotes 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. The JBL Tune Flex have a weight of 9.6g . We prefer a lower weight better for the reason that 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.

ANC makes use of advanced kind of tech to actively cancel noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (noise) and producing -1 (inverted noise) to make zero therefore "diluting" the noise.

JBL Tune Flex have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to overcome background sounds.

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

The sound pressure level, is the pressure level of sound, measured 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.

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.
