Technical Considerations of in Ear Monitors

When selecting in-ear monitors you would have already gone over the decision numerous times, taking into consideration all administrative and physical requirements. But still there is one aspect of selection which you may have ignored and which may make you to select inappropriate equipment, causing you loss of money effort and time. So whenever you are selecting in-ear monitors for your performance do take the following technical aspects into account

  1. Frequency Response: Human voice and hearing is capable of producing and listening to frequencies from 20 Hz to 20 KHz. While selecting the in-ear monitor you must ensure what all frequencies it is capable of reproducing. Some monitors tend to falter at high frequencies and instead of reproducing them correctly, may give noise and distortion.
  2. Isolation Provided: Isolation provided by ear monitors means how much outside noise or distortion it blocks. The noise or distortion is measured in dB (decibels). The greater the dB rating, the greater amount of noise it will block and allow the user to hear to mixer sounds more intently. Hence the greater the dB the better it is.
  3. Sensitivity: Sensitivity means that at a given power how much volume would an in-ear monitor produce. Monitors which are less sensitive tend to produce less volume at a given power and thus in order to provide the user with the adequate and desirable volume, more power will be required. This will lead to more consumption of mixing equipment’s power. Thus more sensitive ear monitors are the better ones.
  4. Impedance: Impedance is the inbuilt resistance that exists in any electrical or electronic device. It is measured in Ohms. The value of any equipment’s impedance greatly dictates how much output it will provide. Specially in case of speakers and ear monitors where the output is in the form of sound, this factor attains utmost importance. More impedance means more resistance and less sound or volume produced over a given power. And less impedance means better volume given as output to a fixed amount of power. Therefore always try to select an in-ear monitor with low impedance. Although slight variations in the impedance reading may not affect your choice that much, but certainly you should look out for sharp differences in impedance readings when selecting the gadget.
  5. Sound: At the end of it, all boils down to one aspect. How does the ear monitor sound? If it sounds as near to reality as possible it is the best choice for you. However sometimes quality is not the only factor you consider while selecting them. Budget constraints play a major role when deciding your quality of equipment. Buying a single in-ear monitor may not appear to be that expensive an exercise, but when you have a crew of 35 to 40 people, all of whom need ear monitors and that too wireless, it amounts to sizable money. Even when making a trade off between cost and quality, keep in mind not to compromise on quality too much as that would cost you later on.
