What You should Look for in Headsets?
Video conferencing and telephone conversations replaced face-to-face meetings particularly during the pandemic. However, remote communication has become a part of the workflow and everyday life, so many now need a special headset for online communication. For this, wired or wireless headphones with a microphone may be suitable, which should transmit the sound of high quality, not interfere during work and not create discomfort.
We will tell you how to find a suitable device and what parameters you need to pay attention to when buying. We will consider the positive and negative aspects of different models, their design, and methods of connecting to various devices in detail.
The type of connection divides headphones into two types: wired and wireless.
Wired models provide stable audio transmission without interference or the need for recharging. Besides, the cable protects the signal from noise and allows for better sound transmission to the headphones.
Wireless devices provide users with comfort and freedom of movement near the devices to which they are connected: you can move freely from the computer for 10-30 meters, depending on the built-in Bluetooth module and antenna. In addition, you do not have to be tangled up in wires.
A wired audio set is connected using USB-A, Type-C cables or jack, mini-jack, and micro-jack connectors. The first option is the most common for use with PCs and laptops. Headphones with a USB connector have a built-in sound card, and using the buttons on the body or the wire of the device; you can adjust the volume and turn the microphone on and off.
A 3.5 mm mini-jack is considered a classic and universal option for connection – it is suitable for a computer, mobile phone, audio player, home theater and is used by most manufacturers.
The wireless audio set connects via Bluetooth, Wi-Fi, radio, or infrared sensors. The range of the Bluetooth set is from 10 to 200 meters and depends on the adapter version. For example, a new module – Bluetooth 5.2, which claims a working distance of up to 240 meters, four times the 60 meters allowed by Bluetooth 4.2. This type of device can be used to listen to music and play games and for business purposes, such as audio and video conferencing.
When buying, pay attention to the frequency range, complex impedance and input power.
- Frequency Range shows a list of audio frequencies that the speakers can reproduce. Typical values are between 20 and 20,000 Hz.
- Resistance (impedance) affects electricity consumption, determines the allowable load limit, and indicates how powerful the amplifier needs to be. For example, a device with a complex impedance of 16 to 32 ohms is suitable for mobile phones. For PCs and laptops, devices with an indicator of at least 120 ohms are required.
- The allowed input power should be 1-5000 mV, and the more energy is supplied, the louder the headphones play. If the power supply is higher than a certain level, the speaker may be damaged.
It is also essential to research the characteristics of the headset. The higher the sensitivity, the louder the microphone will transmit sound. Still, the frequency range is less significant since the human ear perceives it in the field from 20 to 20,000 Hz, which corresponds to the standard parameters of most audio devices. In addition, attention should be paid to the active noise canceling function, impedance characteristic, and speaker power. For wireless sets, an important criterion is the battery capacity and its type.
