Understand the Importance of Them to Your Headphone

Power and design are some of the features that users most pay attention to when buying a headphone.Despite this, there are other properties essential for sound quality, such as impedance and frequency response.These specifications are not always remembered by consumers, but may have a direct influence on the definition of audio output from the speakers.

Find out which type of headphone suits you best

Buying a headset can become a simpler task if you know the essential details of a good data sheet.So, better understand the importance of impedance and frequency for your headphone.These tips can increase the chances of you finding an accessory with powerful and clean sound.

What matters about the impedance?

Among the important properties for the sound quality of the headphone , the impedance may be one of those responsible for improving the definition of sound.This is because the impedance is the pressure that prevents specific noises from interfering with the reproduction of the audio.

Like any other electronic device, headphones have an electric current that passes through the internal circuit.This charge that circulates through the device generates noises that can impact the definition of the sound.Measured in ohms (Ω), the impedance acts as an inhibitor of these noises, as a force that goes against the hisses caused by the energy present in the headset.

Therefore, the greater the impedance in a heaphone, the more chances this device has to offer clean audio – it is worth noting that this is not always so, after all, other factors may decrease or increase the importance of the impedance in a phone, such as power and response of frequency.

Buying a high impedance headphone, however, can ensure higher sound quality in most cases.High-end headphones generally have an above-average amount of impedance – 28 ohms, on average – such as the Koss Porta Pro (price of $ 450 and 60 ohms impedance), the Shure SE535 ($ 1,700 and $ 36 ohms) and the Sennheiser HD25-1 II ($ 1,200 and 70 ohms).

Frequency response:what does the property say about a headphone?

The frequency response indicates the limits that the sound of the device can reach, be it the minimum or maximum level, and not necessarily the quality.The human ear is able to hear sounds in a frequency of 20 Hz to 20 kHz.With this, obviously, the audio output from the headset speakers must be within that range.

Logically, sound accessories that offer greater amplitude of frequency response also bring in more complete sounds, which means, in practice, songs in more detail such as instruments, well-defined vocal and sound effects.However, it is worth remembering that it is unusual for bands and other sounds to reach the extremes of this range, be it 20 Hz or 20 kHz.

If it is possible, it is worth investing in a headset with a frequency response of 20 Hz to 20 kHz, but not doing so does not mean buying a lower quality headphone.After all, it is possible for a headphone with a frequency response of 24 Hz to 16 kHz to have audio quality similar to that of an accessory that allows you to reach the limits of what the human being can hear.

In Brazil, there are several models with frequencies ranging from 20 Hz to 20 kHz for various prices, such as JBL Duet BT (costing R $ 499), Razer Adaro (price of R $ 433) and Knup Kp-350 ).
