How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, universal-fit on-ear headset that works across almost any student device and survives being shoved in a backpack, choose ThinkWrite Technologies TWT Audio Ergo; if you need a single-ear, Microsoft Teams-certified office headset with USB-C and hands-on call controls, choose EPOS Impact 100.
• ThinkWrite Technologies TWT Audio Ergo biggest strength: a 3.5mm TRRS plug that fits iPads, Chromebooks, Kindle Fire tablets, Android tablets and laptops, plus a 2-year warranty and a build aimed at hard daily use.
• ThinkWrite Technologies TWT Audio Ergo biggest trade-off: it's a wired analog headset with no call controls, no active noise cancellation and no USB option, so it lives or dies by whether your device has a headphone jack.
• EPOS Impact 100 biggest strength: Microsoft Teams certification with a dedicated Teams button, notification alerts, and backlit in-line volume and mute controls over USB-C (with a USB-A adapter in the box).
• EPOS Impact 100 biggest trade-off: it's a mono, single-ear design, so it's for calls and meetings, not for immersive music or gaming, and it assumes you have a USB port free.
• Pick the ThinkWrite Technologies TWT Audio Ergo if you're a student, teacher or parent buying for a classroom or distance learning setup.
• Pick the EPOS Impact 100 if you work in an office, open-plan space or call center and live inside Teams all day.
The TW110 is a 3.5mm wired on-ear headset with a 30mm dynamic driver, 32-ohm impedance and a 20 Hz – 20 kHz frequency range. That's a full-range audio curve rather than a narrow voice-only band, which is exactly why the spec sheet lists music, console and PC gaming, distance learning, office work and even ASMR as intended uses. It's a general-purpose listening headset first, with a headset mic bolted on.
The microphone is an omni-directional flip-down boom. Omni-directional means it picks up sound from around the capsule rather than a tight front-facing cone, and ThinkWrite pairs it with noise-reducing processing. In practice, that's a sensible choice for a headset that gets passed between students or moved between a bedroom desk and a classroom table: you don't have to park the boom an inch from your mouth for your voice to register.
Should you skip it? Yes, if you need USB connectivity, hardware mute buttons, a Teams button, or active noise cancellation. There are none of those here. It's also on-ear with a plastic enclosure, so it's a practical tool rather than a plush, isolating listening cocoon. But for a student, teacher, or anyone who wants one wired headset that plugs into nearly everything with a 3.5mm jack, this is a straightforward, well-reasoned pick. Check the current price on Amazon before you commit, since that's the part I can't tell you.
EPOS Impact 100: Who It's For
The Impact 100 MS is a different animal entirely. It's a mono, single-ear USB-C headset with a leather and silicone build, soft silicone side support, and a flexible noise-cancelling boom microphone. The single-ear design is the whole point: one ear stays open to your surroundings, so you can hear a colleague walk up behind you or catch a fire alarm while you're on a call. That's a deliberate choice for busy offices, open-plan workspaces, call centers and remote work, not a compromise.
The connectivity is USB-C, and EPOS includes a USB-A adapter in the box — along with a cable, protective case and user manual. That combination covers modern laptops and mobile devices plus older desktops in one purchase, which matters if you move between a hot desk and a home setup. The microphone is noise-cancelling with a flexible boom arm, so you can position it close to your mouth and let the processing handle the background chatter.
The feature that separates this from the ThinkWrite unit is control. You get backlit in-line buttons for volume, mute and Teams alerts, plus a dedicated Microsoft Teams button with notification alerts. That's Microsoft Teams certification, which means the headset is built to work with the platform's call and alert behavior rather than just being "compatible." The spec sheet also lists active noise cancellation and a push-button controller. Note the audio specs: 40-ohm impedance, 86 dB sensitivity, and a frequency range listed at 8 kHz — this is a voice-first headset tuned for intelligible speech, not a music or gaming headset.
Skip it if you want to listen to music in stereo, play games with positional audio, or use a device with no USB port at all. Mono means one ear, and that's a feature for calls and a limitation for everything else.
• Best for school, classroom and distance learning → ThinkWrite Technologies TWT Audio Ergo. The 3.5mm TRRS jack fits iPads, Chromebooks, Kindle Fire, Android tablets and laptops, and the chew-resistant cable and 2-year warranty suit shared or student use.
• Best for professional UC, Microsoft Teams and call centers → EPOS Impact 100. Teams certification, a dedicated Teams button, notification alerts and backlit volume/mute controls are built for exactly that workflow.
• Best for keeping one ear open to your surroundings → EPOS Impact 100. The mono, single-ear design with soft silicone side support is made for open-plan offices.
• Best for listening to music, gaming or general use → ThinkWrite Technologies TWT Audio Ergo. A 20 Hz – 20 kHz range and 30mm dynamic drivers are a full-range listening setup; the Impact 100's 8 kHz voice-focused tuning is not.
• Best for plug-and-play across the widest range of devices → ThinkWrite Technologies TWT Audio Ergo. A 3.5mm analog jack works on anything with a headphone port, no adapter or driver behavior to think about.
• Best for hardware call controls → EPOS Impact 100. In-line backlit volume, mute, and Teams alert buttons versus no controls at all on the TW110.
• Best for background-noise rejection on your voice → EPOS Impact 100. A flexible boom with a noise-cancelling mic and active noise cancellation, versus the TW110's omni-directional noise-reducing boom.
• Best for durability against rough handling by kids → ThinkWrite Technologies TWT Audio Ergo. The flexible ergonomic frame and chew-resistant fabric cable are specified with hardwearing use in mind.
If I were buying for a student, a classroom, or a household where one headset has to work with a Chromebook today and an iPad tomorrow, I'd buy the ThinkWrite Technologies TWT Audio Ergo. The 3.5mm TRRS plug, the full-range 20 Hz – 20 kHz audio curve, the flexible frame and the 2-year warranty make it the more broadly useful object. If I were equipping myself for a job that runs on Microsoft Teams — calls, meetings, webinars, a shared office — I'd buy the EPOS Impact 100 instead, because Teams certification, hardware mute and volume, and the single-ear design are worth more than versatility in that specific context. In my opinion, the deciding question isn't which is better; it's whether your day is listening or talking.
FAQ
Yes. It's a Microsoft Teams certified mono headset with a dedicated Teams button and notification alerts, plus backlit in-line controls for volume and mute. The ThinkWrite TW110 has no call controls and is not Teams-specific.
Yes. Its frequency range is 20 Hz – 20 kHz with 30mm dynamic drivers and 32-ohm impedance, which suits music, console and PC gaming, and distance learning. The EPOS Impact 100 is a mono, voice-first headset with an 8 kHz frequency response, so it's the wrong tool for immersive listening.
They solve it differently. The EPOS Impact 100 uses a flexible noise-cancelling boom microphone plus active noise cancellation, which is aimed at filtering office noise around your voice. The ThinkWrite TW110 uses an omni-directional, noise-reducing flip-down boom — practical for a headset that gets repositioned often, but it isn't a Teams-tuned office mic.
