Specs that actually matter: USB vs Wireless, noise-cancelling mics, certification, call-centre durability
There are many criteria that a new headset must satisfy– it’s tough to wade through all the descriptions of features of all the headsets on offer, even to begin to decide what you actually need and want. Below is a practical guide outlining the important specifications to consider.
So, let’s talk about those features…
Connection
This is how your new headset connects to your computer. Different connections affect mobility, audio reliability, and overall convenience.
What are the options?
Connection: What are the benefits/ disadvantages?
Wired (USB-A/ USB-C): No battery to charge, so they’re ideal for all-day, continuous use; highly reliable; typically more affordable and a better sound quality; simple set-up; however, being plugged in limits movement.
2.4GHz Wireless: Wireless option that often provides higher audio quality than Bluetooth, due to less audio compression.
Bluetooth (wireless): Offers broad compatibility with laptops, tablets, and mobiles, for flexibility and movement, and easy device switching.
Microphone
Clarity is one of the most important aspects of a new headset.
What are the options?
Boom Microphones – these can be positioned closer to the mouth for clearer capture. Many headset models offer extra features for ease and convenience, like flip-to-mute or lift-to-mute functions, for intuitive call control and reduced hassle.
Noise-Cancelling Microphones – these reduce or entirely block background noise for the best speech clarity from your end. They are ideal if you work in a busy office, a shared workspace like a café, or even when hybrid working in home environments with children, pets, or ambient noises like the dishwasher or washing machine.
Noise control doesn’t just apply to the microphone but also to what you hear. When it comes to noise-cancelling, there are two terms you’ll see that come up over and over again: ANC, active noise-cancelling, and PNC/ PNI, passive noise cancellation, or sometimes called passive noise isolation. Both aim to quieten outside noise that may be a distraction, but they work quite differently.
If you’re not sure what they mean, we’ll explain:
PNC, or PNI, works by creating a physical seal with the ear pads or in-ear tips. This acts as a physical barrier to outside noise. The headset isolates you from ambient noise rather than using technology to actively cancel it out. It means that you can listen to the call at lower volume levels, which is better for your ears, because you don’t have to counteract the sounds of your environment. Also, you don’t need additional battery power to take advantage of the passive noise isolation.
ANC is when your headset neutralises ambient noise– secondary microphones are incorporated into your headset to listen to outside noise and generate phase-inverted sound to effectively cancel out that noise before it reaches your ears or gets added to the outgoing audio of your speech. In other words, ANC technology listens, then creates equal but opposite noise to the unwanted ambient sounds. This requires additional battery power, meaning a full charge doesn’t.
Call-centre Durability (& Comfort)
It is necessary that your new headset withstands constant daily use, in terms of durability and wearability. Comfort is very important for a long-lasting headset.
What to consider when choosing your headset?
Style (not how they look!) – in-ear, on-ear, and over-ear are the three options typically available. Choose based on what you find most comfortable to wear for long periods and what is less bothersome to remove and put back often. You may find that in-ear styles fall out of your ears, or you may find it annoying to slip the over-ear pads off one ear to speak to a colleague. You may prefer a headset with a headband, a microphone, and only one ear pad.
Construction – a metal-reinforced band is designed for long-term durability, but making sure it is lightweight for all-day use is just as important. The headset may last, but your willingness to wear something heavy, or sweaty, or just plain uncomfortable may run out before the headset’s life is up.
Comfort and adjustability – cushioned ear-pads, adjustable headbands, soft leatherette pad covers, cooling-gel earpads, swivel earcups, and dual-hinge designs may be features to look out for to reduce wearing fatigue and maintain comfort.
Extra features for ease and performance – longer cables are often chosen for models destined for call-centres to help handle extra movement. Some models have bendable, pivoting boom microphones for enhanced flexibility and optimal microphone positioning. Some models offer safe listening limits to help protect your hearing over long sessions. In-line (on the wire) or on-ear controls (buttons on the frame of the headset) are desirable for efficiency– they often include mute buttons, volume controls, and lights to visibly indicate that you are busy.
Certification
Certification provides assurance of consistent and high-quality performance.
A Microsoft Teams Certification means that the headset has met Microsoft’s strict performance standards. In practical terms, this means that:
- The product has undergone a rigorous independent lab testing process,
- The product is compatible and well-suited to the Teams ecosystem, meaning the hardware and Teams features will operate without conflict.
- The product has reliable audio processing and includes Teams-supported features such as call controls, audio tuning, and advanced microphone processing.
