A couple of decades ago, a device such as a headphone amplifier was very scarce and not in great demand. It should be noted that before consumers were not provided with such a wide selection of equipment and it was bought mainly by people who were professionally engaged in music. Times are changing for the better, now customers have the opportunity to choose a device that amplifies the sound, completely falling under their taste preferences and falling into a certain price category.
Today, a headphone sound amplifier is needed not only for professional musicians, but also for simple music lovers or people with a delicate
ear for music. It should be noted that the finer the ear, the better the headphones that produce absolutely all frequencies are required. But due to the mediocre performance of the headphone output in household audio equipment, very often there are problems with coordinating the power of the speakers with the device. Since the signal level is very low, the sound is reproduced quietly, and some frequencies are cut off altogether.
Here, many music lovers face a difficult choice: buy cheap headphones that fit the equipment, or purchase high-quality devices that are not compatible with sound cards. And in the first and in the second case, you do not have to wait for high-quality sound. To solve this dilemma, a headphone amplifier will help, which will become the link between the listening device itself and the sound cards of audio equipment.
High-impedance headphones with high quality and transmitting sound as accurately as possible require amplification of the incoming signal. If their characteristics are from 300 Ohm or more, then a headphone amplifier is required without fail, because the maximum level should reach 6 V. It should be noted that today there is a very large selection of headsets offered by different manufacturers, it differs in design and, of course the same characteristics. There can be a rather wide range of impedances - from 30 to 600 Ohms, so as not to experiment, it is better to immediately buy a pocket headphone amplifier in addition.
The source also plays an important role, if it is of poor quality and reproduces dirty sound, then it will be clearly audible with the amplifier, especially if the headphones themselves are high-quality and pay utmost attention to details. In this case, you won’t be able to enjoy great music, all the equipment should be with good characteristics.
Today, buying a headphone amplifier will not be difficult, because the choice is very wide. For some manufacturers, this equipment has become the main one in production, so they are especially serious about manufacturing these devices. Amplifiers should fit headphones as accurately as possible, because only in this case they can provide such high fidelity of sound reproduction, which is many times superior to the most expensive speakers.
In any case, each consumer selects equipment based on their own preferences and, of course, financial capabilities, and manufacturers provide a wide selection of amplifiers designed for different categories of customers.
