• ThinkWrite Technologies TWT Audio Ergo — biggest strength: a flip-down omni directional boom mic plus in-line volume control on a wired USB-A connection, built for talking and listening at a desk for hours.
• ThinkWrite Technologies TWT Audio Ergo — biggest trade-off: it is wired, so you are tethered to a USB-A port with a 1.3m cord and no Bluetooth at all.
• Aurotlu Open Ear Clip — biggest strength: true wireless freedom with Bluetooth 5.4, an open-ear clip design, IPX7 water resistance and a charging case that extends total playtime to roughly 60 hours.
• Aurotlu Open Ear Clip — biggest trade-off: there is no boom mic and no wired option, so it depends on battery and Bluetooth pairing for everything.
• Who each pick is for: the ThinkWrite for students, teachers, office workers and anyone on calls at a computer; the Aurotlu for runners, walkers, gym-goers and people who want to hear traffic and surroundings while listening.
The TW220 is a purpose-built over-ear headset, and its whole personality comes from two things: the USB-A cable and the microphone boom. That flip-down omni directional mic is the headline feature. It is designed to capture a wide range of vocal qualities and inflections while reducing common background noise, which is exactly what you want if your day involves speaking to a class, a meeting or a recording rather than just listening. The in-line roller wheel for volume means you can adjust levels by touch without alt-tabbing into software, and that small convenience matters more than it sounds during a long session.
Comfort and durability are clearly the other priorities. The ear cushions are ergonomically shaped and made from polyurethane, with passive noise cancellation doing the work of keeping external sound out. The headband uses adjustable compression so it can be sized to your head rather than clamping down. The frame is described as strong and flexible, and the cable is chew-resistant fabric — a detail that makes a lot of sense in a school setting where headsets get shoved into bags and handled by kids. The 40mm dynamic drivers and 32 ohm impedance are standard, sensible numbers for clear everyday audio, and the 7.84-ounce build is light enough for long stretches. A 2-year warranty rounds it out.
So who should buy it? Students doing distance learning, teachers running a classroom or virtual lesson, office workers who live on softphone calls, and anyone pairing a headset to an iPad, Chromebook, Kindle Fire, Android tablet or laptop over USB-A. Who should skip it? Anyone who wants to move around while listening. There is no Bluetooth here, the 1.3m cord anchors you to the machine, and if you want to run or lift weights with music on, this is the wrong shape of product entirely.
The Aurotlu is the opposite philosophy: nothing touches your ear canal, nothing is plugged in, and nothing holds you in place. The clip-on open-ear design sits against the natural curve of your ear, which means you stay aware of your surroundings — traffic, a training partner, a colleague walking up behind you. That awareness is the entire point of open-ear audio, and it is why this style has become so popular for running and outdoor walking.
The wireless side is well specified for the category. Bluetooth 5.4 promises faster, more stable transmission with low latency and quick pairing, and touch controls let you handle playback and calls with a tap. The battery story is the standout: 12 hours of continuous play on a single charge, an additional 48 hours from the magnetic charging case, and up to 80 hours of standby, with the case refilling in about an hour over USB-C. IPX7 water resistance means sweat and rain are not a concern. The 16.3mm dynamic drivers are large for this form factor, and the brand positions them for both rich music reproduction and clear voice pickup on calls.
Who should buy it? Runners, walkers, cyclists at a relaxed pace, gym users, and office or hybrid workers who want background music without sealing off the world. It is also a good fit if you dislike the pressure of in-ear tips over long periods. Who should skip it? Anyone who needs a dedicated boom microphone for teaching, recording or long conference calls, and anyone who wants zero dependence on charging. The warranty is listed at 3 months, which is short, so treat it as a device to look after.

My Verdict
The ThinkWrite, clearly. It has a flip-down omni directional boom microphone designed for voice pickup and a wired USB-A connection, so there is no pairing or latency to worry about. The Aurotlu relies on its built-in mic in a fully wireless open-ear design.
Yes, within reason. It carries an IPX7 water resistance rating, so sweat and rain are covered. That said, IPX7 describes resistance to water exposure, not unlimited submersion, so I would not swim with them.
No, and that is the point. It is a wired USB-A headset with a 1.3m cord and in-line volume control, compatible with iPads, Chromebooks, Kindle Fire, Android tablets and laptops. There is no Bluetooth radio in it.
Only one has a battery. The Aurotlu offers 12 hours of continuous play per charge, an extra 48 hours from its charging case, up to 80 hours of standby, and roughly a 1-hour case recharge over USB-C. The ThinkWrite draws power from the USB port it is plugged into, so there is nothing to charge.
Value depends on your use. For desk, classroom and call duty, the ThinkWrite's 2-year warranty and durable build make it the more sensible long-term pick in my opinion. For workouts and outdoor listening, the Aurotlu's wireless freedom and charging case are what you are paying for. Either way, check the current price on Amazon before you commit, since that is the one number that decides whether a product is worth it to you.
