These two headsets look similar on a shelf, but they solve different problems. One is built to cut the cord and roam. The other is built to stay wired, stay simple, and stay on a desk. Getting that choice right matters more than any spec sheet headline, because the wrong pick means fighting your own gear every day.
• Global Teck Worldwide Evolve2 — biggest strength: wireless freedom with dual Bluetooth, a bundled Link 380 USB adapter, and up to 35 hours of talk time, so you can move between PC, phone, and tablet without unplugging anything.
• Global Teck Worldwide Evolve2 — biggest trade-off: it is a mono over-ear design with passive noise cancellation only, so it blocks less ambient sound than an active system and it needs charging, unlike a wired headset.
• EPOS Impact 100 — biggest strength: Microsoft Teams certification with a dedicated Teams button and notification alerts, plus USB-C with an included USB-A adapter, so it connects to almost anything without drivers or pairing.
• EPOS Impact 100 — biggest trade-off: it is wired and mono, so you are tethered to your desk and there is no battery to free you — the cable is the whole point and the whole limitation.
• Pick Global Teck Worldwide Evolve2 if you take calls while walking around, split time between a laptop and a phone, and want one headset that follows you.
• Pick EPOS Impact 100 if you sit at a fixed workstation, live inside Microsoft Teams, and want zero setup friction and no charging routine.
The Evolve2 bundle is really three things in one box: the Evolve2 65 mono headset, the Jabra Link 380 USB Bluetooth adapter, and a Global Teck priority support plan. That adapter matters more than it looks. It is what lets the headset talk to a PC or Mac the way a proper wireless headset should, while dual Bluetooth connectivity lets you stay paired to a smartphone or tablet at the same time. If you have ever juggled a laptop call and a mobile call in the same hour, that simultaneous pairing is the feature you will actually feel.
The microphone setup is three digital hybrid microphones, and the boom arm has a genuinely useful trick: swing it up to mute, swing it down to unmute or answer a call. That is a physical mute you can trust in a way a software toggle never quite is. On the flip side, noise control here is passive — the oval over-ear cups seal out some office noise, but there is no active cancellation. And because it is mono, you get one ear covered, which is great for staying aware of your surroundings but not ideal if you want to shut the world out.
Who should buy it: remote and hybrid workers who move around, split time across PC and mobile, and want a single wireless headset that handles Teams, Zoom, Webex, RingCentral, 8x8, Skype, Google Hangouts, GoToMeeting, and Vonage. Who should skip it: anyone who wants a purely wired, always-ready desk headset, or anyone who needs stereo audio or real active noise cancellation.
EPOS Impact 100: Who It's For
The Impact 100 MS Mono is the opposite philosophy, and it is a coherent one. It is a wired, mono, on-ear headset with USB-C connectivity and an included USB-A adapter, so it plugs into a laptop, desktop, or mobile device and simply works. No pairing. No dongle to lose. No battery to remember. For a fixed workstation, that is a feature, not a compromise — you sit down, plug in, and you are on.
The headset is Microsoft Teams certified, which shows up in concrete ways: a dedicated Teams button, notification alerts, and backlit in-line call controls for volume, mute, and Teams alerts. If your workday is a carousel of Teams meetings, having the controls on the cable rather than buried in an app removes a small but constant friction. The flexible noise-cancelling boom microphone is aimed at busy offices and open-plan spaces, filtering background chatter so your voice comes through clearly.
Comfort is clearly a design priority. Soft silicone side support is there to keep a single-ear headset stable through a long day, and at 51 g it is a light piece of gear. The on-ear, single-ear format keeps one ear open to your environment — useful in a shared office, less useful if you are trying to disappear into deep focus. Noise control is listed as active, and the enclosure uses leather and silicone with a dynamic driver rated at 40 ohms and 86 dB sensitivity across an 8 KHz frequency range — a voice-optimized profile rather than a hi-fi one. You also get a protective case and adapter in the box, backed by a 2-year manufacturer warranty.
Who should buy it: call-center and UC-heavy users, help-desk staff, and anyone with a permanent desk who wants a durable wired headset with dedicated Teams controls. Who should skip it: people who take calls on the move, need stereo sound, or want to walk away from their desk mid-call.
• Best for wireless freedom → Global Teck Worldwide Evolve2. Dual Bluetooth plus the Link 380 adapter and up to 100 ft of range let you leave the desk without ending the call.
• Best for zero-setup reliability → EPOS Impact 100. USB-C with an included USB-A adapter means it plugs in and works, with no pairing or charging routine.
• Best for all-day battery independence → Global Teck Worldwide Evolve2. Up to 35 hours of talk time on a 2-hour charge suits long days and heavy call volume.
• Best for Microsoft Teams workflows → EPOS Impact 100. Teams certification, a dedicated Teams button, and on-cable notification alerts are built around that ecosystem.
• Best for mixed PC-and-phone use → Global Teck Worldwide Evolve2. Simultaneous dual Bluetooth pairing covers your computer and your smartphone or tablet at once.
• Best for a fixed desk in a shared office → EPOS Impact 100. Light at 51 g with silicone side support and a noise-cancelling boom mic tuned for open-plan noise.
• Best for situational awareness with one ear free → either, but for different reasons. Both are mono; the Impact 100 stays tethered, the Evolve2 lets you walk.
• Best for durability under constant daily use → EPOS Impact 100. Wired construction with a protective case and a 2-year manufacturer warranty is built for heavy, stationary use.
If I had to pick one for myself, I would buy the Global Teck Worldwide Evolve2. The reason is simple: the way most of us work now is not stationary. Moving between a laptop and a phone, taking a call while walking to another room, and not thinking about charging until the next morning — that is the workflow the Evolve2 is designed around, and the bundled adapter and dual Bluetooth make it genuinely practical rather than just convenient on paper. I would choose the EPOS Impact 100 instead if my job is anchored to one desk and my calendar is wall-to-wall Teams calls, because a wired, certified headset with on-cable controls is simply less to manage. Both are sound picks. The tiebreaker is whether you sit still or move.
FAQ
Yes. It connects natively over USB-C and ships with a USB-A adapter, so it works with laptops, desktops, and mobile devices that use either port type.
They work differently. The EPOS Impact 100 lists active noise cancellation with a noise-cancelling boom microphone. The Evolve2 relies on passive noise isolation from its over-ear cups plus three digital hybrid microphones for your voice. If blocking room noise is the priority, the EPOS approach is the more aggressive one.
No. It is a wired USB headset with no battery. The Evolve2, by contrast, is wireless with up to 35 hours of talk time and a 2-hour charge time, so it does need recharging.
In my opinion, the Evolve2 suits most home setups better because it is wireless, pairs with both a computer and a phone, and lets you move around the house during calls. The Impact 100 is the stronger choice if you work from a single fixed desk and spend your day in Microsoft Teams.
