Jabra Evolve2 85 MS Stereo Specifications, Tests and Review

Product Jabra Evolve2 85 MS Stereo are wireless headphones with a detachable cable, which combines the advantages of both solutions. The wireless connection option offers freedom of movement while increasing the comfort of use. The detachable cable then provides a listening alternative in the event of a low battery caused by wireless listening. The headphones use the Bluetooth 5.0 technology for sound transmission. The transmission range offered is up to 30 m. The maximum range represents the maximum distance from the audio transmission source that the headphones can be used for wireless audio transmission. However, the maximum communication range can be affected by obstacles such as people, walls, etc.

This type of headphones has a design that surrounds the entire ear to improve isolation from external noise. As a result, they provide a great quality of listening without interference. However, unlike on-ear headphones, they are usually heavier and less suitable for frequent wearing. The weight of the headphones is 286 g.

The sound quality can be affected by many factors. When it comes to frequency range, a wider range will allow more detail to be heard during your listening session. However, it is important to note that the ability to perceive frequencies varies from person to person. The average person is able to hear frequencies in the range of 16 to 20 000 Hz. That is why headphone manufacturers usually focus on the 20 to 20 000 Hz range. If the lower values are lower, headphones are better able to reproduce bass tones, as these represent frequencies up to approximately 256 Hz. Conversely, values from 2 048 Hz upwards are treble. Thus, headphones with a high upper limit will provide a much more accurate reproduction of high tones. Headphones Jabra Evolve2 85 MS Stereo have a frequency range of 20 - 20000 Hz. The Jabra Evolve2 85 MS Stereo reaches the sensitivity values of 117 dB. The sensitivity of the headphones expresses the ability of the headphones to pick up the signal from the source and reproduce it with sufficient volume. The higher the sensitivity, the more easily the signal is converted to sound and the louder the headphones are able to play at a lower power consumption. It is important to remember that high listening volume can consume more energy from connected devices. So if you want to listen to music from your cell phone, it's better to choose headphones with low sensitivity to avoid draining your phone's battery too much. Headphones with a lower sensitivity value (around 85 dB) are better suited for listening in quiet environments, while medium values (around 90 dB) allow for quality listening in noisy environments such as public transport or cafes. Headphones with a high sensitivity value (100 dB or more) are designed for use in really noisy environments such as concerts The maximum input power of these headphones indicates how many decibels they can receive from the device without any damage. For Jabra Evolve2 85 MS Stereo, it is 50 mW.

The headphones are composed of many various components, one of the most important is the diaphragm. Diaphragm transforms the electrical signal into sound and therefore its quality affects the overall listening experience. There are three types of diaphragms: thin, medium-thick, and thicker. A thin 6 mm thick diaphragm responds quickly to high frequencies but less sensitively to bass. The medium-thick 10 mm diaphragm provides a balanced sound profile, allowing you to enjoy both bass and treble. The thicker 20 mm diaphragm is more sensitive to higher frequencies but has a poorer bass response. These headphones are equipped with the 40 mm.

You will also definitely appreciate the special design of the construction that creates a seal that further blocks out ambient noise and which contributes to undisturbed music listening.

For an even more undisturbed listening experience, the headphones have a special Active Noise Canceling feature.

Jabra Evolve2 85 MS Stereo has a boom–type microphone. The microphone sensitivity is -35 dBV/Pascal. A lower microphone sensitivity will generally ensure that even quieter sounds are caught. On the other hand, in noisier environments, distortion of the recording may occur. With a higher sensitivity, the microphone will not distort the recording even in noisy environments. On the other hand, the microphone will not pick up quieter sounds. So it depends on the environment and the purposes you plan to use the headphones for.

These headphones allow simultaneous connection up to 2 devices. This feature allows you to easily switch between listening from your mobile, tablet, or computer without having to switch manually.

In terms of headphone battery life as a significant factor in the purchase decision, it depends on what you want to use the headphones for and potentially how often you will be able to recharge them. Headphones with up to a few hours of battery life are more suitable for home use as they will require more frequent charging. Headphones with a battery life of around 10 hours or more are already more suitable for commuting and shorter journeys. However, nowadays you can also find headphones on the market that have a battery life in the higher tens to hundreds of hours. In this case, you do not have to worry about your headphones simply running out of power on longer journeys, and you will not have to deal with constant recharging. The battery life of the Jabra Evolve2 85 MS Stereo reaches up to 37 hour(s).

Charging time is 2.5 hour(s).
