A headset is one headphone or pair with a built-in microphone. Headsets can be used for apps that require communication i.e. Skype, games with voice chat, mobile phones, etc.
These microphones are designed to filter out background noise from the desired sound. Especially useful in noisy environments.
More microphones result in better sound quality and enable the device to filter out background noise.
There is a control panel on the device body, so you can easily access the volume control or remote without having to interact with a cable or another device it's connected to.
With voice prompts, you will automatically receive information via audio messages – for instance, you may find out that the battery is running low, and it's time to recharge the device.
The device has an option to mute/unmute a conversation directly from the device.
