Before choosing headsets, you might think over it thousands of few times – whether to choose wired or wireless headsets. Each has its pros and cons, which makes it possible in selecting one according to your preferences. These are essential gadgets that perfectly require for attending business calls or listening to music.
When choosing wired or wireless headphones, you need to have at least a general idea of the technical characteristics. Sound quality depends on factors such as frequency range, impedance, sensitivity, power, and percentage of distortion.
Hence, there are a number of factors you might consider while picking one.
So, which to choose?
Let’s find out!
Which to Choose – Wireless or Wired Headsets?
The main feature of a wireless connection is the ability to transmit sound waves not using a cable but through an analogue or digital signal. For this, a Bluetooth module is often used. Thanks to the absence of wires, these headphones are more comfortable and durable. You can take them with you to your workout without worrying about cable tangling. However, they sound worse when compared to their wired counterparts.
Wired headphones are less convenient than Bluetooth devices, but offer better performance and lower cost. Live audio is not re-encoded and retains its original quality. Of course, the presence of a wire can’t completely eliminate distortion, but it significantly reduces it.
The frequency range is the band of frequencies that the headphones are capable of reproducing. The wider it’s, the better and more detailed the sound. The default value is 20 to 20,000 Hz, but there are devices with a range greater than 100,000 Hz. Manufacturers often inflate the numbers in order to attract buyers. When measuring, the presence of a certain frequency is indicated, and not its loudness. Therefore, it’s better to focus on the frequency response.
Impedance is an important metric that affects the quality of the reproduced sound and the consumption of electricity. It largely determines the compatibility of headphones with a smartphone or player. Any device has a conditional supported range of loads. For portable equipment, headsets with an impedance of 16 to 32 ohms are suitable. Accordingly, this figure will be higher for professional audio amplifiers.
The sensitivity determines how loudly the device can play music. The official pointer for current models is from 90 to 120 dB, but there are also quieter ones. The higher the sensitivity, the louder the sound and less load on the player. They also like to overestimate this characteristic. Usually, the cheaper the headsets, the quieter they play.
Headset power is indicated in watts. It affects the quality and volume of the sound. The more watts, the faster the mobile phone will be discharged. It’s better to choose devices with medium power if you don’t plan to use an additional amplifier.
Distortion is indicated as a percentage. It’s influenced by many factors, including the characteristics of the built-in amplifier in the player or smartphone. The lower the distortion percentage, the better the reproduction quality. Good headphones have 1-2% distortion. Models with the same specifications may sound different. Modern measuring devices aren’t yet able to perceive sound in a complex way, as a person does. Therefore, before buying headsets, you need to independently evaluate their quality in the store.
Due to the fact that wireless headphones still can’t boast perfect sound, many users prefer wired headphones. Headsets with good sound quality are an expensive accessory that needs to be carefully chosen.
You shouldn’t neglect the opportunity to test Plantronics, Sennheiser, or JABRA headsets before buying, because different manufacturers have different attitudes towards the quality of the product. Headsets with the same declared characteristics on the packaging don’t show themselves equally in practice.
