How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one headset to carry you through back-to-back meeting days with a charging case that keeps going long after a single charge would die, choose Delton Headset; if you need an open-ear fit that never plugs your ears and stays comfortable through marathon call-center shifts, choose Smof Open Ear Headphones.
• Delton Headset biggest strength: A charging case that pushes total talk time to 108 hours, plus a noise-cancelling mic and DSP tuned for Teams, Zoom, and Google Meet.
• Delton Headset biggest trade-off: It's an in-ear bud design, so anyone who dislikes something sitting inside the ear canal won't love it.
• Smof Open Ear Headphones biggest strength: An open-ear, air-conduction fit with a flexible boom mic and a mute button — nothing enters your ear, so soreness over long shifts is a non-issue.
• Smof Open Ear Headphones biggest trade-off: 10 hours of playtime per charge and no charging case, so heavy users need to plug in daily.
• Who Delton is for: Professionals who live in Microsoft Teams and want maximum talk time with call controls baked in.
• Who Smof is for: Call-center staff, truck drivers, and remote workers who want all-day comfort and a physical mute button.
The Delton 95X is built around one idea: keep a working professional on calls without interruption. The standout number is 108 hours of total talk time — the earpiece itself delivers 18 hours, and the included charging case adds another 90. That's a design choice that matters if your calendar is a wall of meetings and you don't want to think about a charger mid-afternoon. For someone who takes calls from a desk, a car, and a home office in the same day, that case is the difference between a tool and a hassle.
The platform story is just as deliberate. This headset is made specifically for Microsoft Teams, with a multi-function button that lets you answer and end calls on Teams, and it also plays nicely with Google Meet, Zoom, Slack, and Skype. There's a USB dongle included alongside Bluetooth, which is the kind of detail that matters when you want a stable connection to a laptop that isn't always cooperative about wireless audio. Bluetooth range is listed at 30 feet, so you can step away from your desk and stay on the line.
On the audio side, you get a noise-cancelling microphone with DSP processing to reduce background noise, and a 13 mm dynamic driver covering 20 Hz to 20,000 Hz. Controls cover volume, power, mic mute, and that Teams button, and the touch-based call control keeps things clean. Comfort-wise, it's an in-ear bud with plush cushions and an adjustable, contoured fit for either ear, plus a water-resistant build for daily wear. The trade-off is the form factor itself. If you've never liked earbuds, the Delton won't convert you — this is a headset for people who are fine with something in the ear and want the longest possible runtime.
Who should buy it: Teams-heavy professionals, hybrid workers juggling multiple platforms, and anyone who wants two-way charging (case or USB-C) and a 1-year manufacturer warranty backing the purchase.
Who should skip it: Anyone who gets ear fatigue from in-ear buds, or who prefers a boom mic they can physically swing toward their mouth.
The Smof 5816B takes the opposite approach. It's an open-ear, air-conduction design, which means the driver sits outside your ear canal rather than inside it. The pitch is simple and believable from the specs: no soreness, even over extended use. For call-center agents, online teachers, or anyone wearing a headset for a full shift, that's not a small thing. Ear fatigue is the reason a lot of people abandon traditional headsets, and the open-ear shape sidesteps it entirely.
The mic setup is the second differentiator. Smof pairs ENC noise cancellation with a flexible boom mic, and there's a dedicated mute button. A boom mic you can position close to your mouth tends to be the more reliable choice in a noisy room, and a physical mute button beats hunting for a touch control when you need silence immediately. The housing is ABS plastic, black, and the controls are push-button — less flashy than touch, but predictable, which some people genuinely prefer.
Connectivity is where Smof makes a specific bet. It uses Bluetooth 5.1 with aptX, aptX-LL, and aptX-HD encoding, and ships with a USB-A and USB-C dongle. The low-latency encoding matters for anyone doing calls where audio sync is noticeable. One honest caveat straight from the specs: the dongle is for wireless transmission to PS4, PS5, and PC, and it is not intended for Bluetooth mice and keyboards. That's a niche limitation, but worth knowing before you buy.
Battery is the clear trade-off. The 250 mAh battery charges fully in 1.5 hours and gives up to 10 hours of music and calls. That's enough for a normal workday, but there's no charging case to extend it, so this is a plug-in-every-night device. Smof backs it with a 2-year warranty, which is a longer coverage window than Delton offers.
Who should buy it: Call-center staff, truck drivers, remote workers, and online learners who want open-ear comfort, a boom mic, and a mute button — and who are fine charging daily.
Who should skip it: Anyone who needs multi-day battery life or who wants a case that doubles as a charger.
• Best for battery life → Delton Headset. 108 hours total talk time versus Smof's 10 hours per charge is not close.
• Best for all-day comfort without ear fatigue → Smof Open Ear Headphones. The open-ear design avoids in-canal pressure entirely.
• Best for Microsoft Teams users → Delton Headset. It's purpose-built for Teams with a dedicated answer/end call button.
• Best for noisy environments and quick muting → Smof Open Ear Headphones. ENC plus a flexible boom mic and a physical mute button.
• Best for travel and hybrid workdays → Delton Headset. The charging case and two-way charging (USB-C or case) suit life on the move.
• Best for low-latency gaming and PC audio → Smof Open Ear Headphones. aptX-LL and the USB-A/USB-C dongle target PS4, PS5, and PC.
• Best for warranty coverage → Smof Open Ear Headphones. 2 years versus Delton's 1 year.
• Best for touch controls and a sleek single-bud look → Delton Headset. Touch call control and a compact 13 mm dynamic driver in a single earpiece.
In my opinion, the Delton Headset is the one I'd buy. The 108-hour combined battery with the charging case, the Teams-first design, and the USB dongle plus Bluetooth flexibility make it the more capable tool for the way most people actually work — long days, multiple platforms, and no patience for a dead headset. The Smof is the better pick only if open-ear comfort and a boom mic are non-negotiable for you. If that's your priority, it's a genuinely good choice; just plan on charging it every night. Either way, check the current price on Amazon before you commit, since that's the one variable that can tip a close call.
For Teams-centric work, yes — in my opinion. The Delton has a dedicated Teams answer/end button, 108 hours of total talk time, and DSP noise cancellation. The Smof is a solid work headset too, but its strength is open-ear comfort rather than platform integration.
No — the opposite. Smof gives up to 10 hours per charge with a 1.5-hour charge time and no case. Delton's earpiece alone runs 18 hours, and the charging case extends that to 108 hours total.
Both handle noise, but differently. Smof pairs ENC with a flexible boom mic you can position near your mouth, plus a mute button. Delton relies on a noise-cancelling mic with DSP. If you want physical mic placement and instant muting, Smof fits better; if you want a cleaner single-bud setup, Delton does.
Delton includes a USB dongle plus Bluetooth and works across Teams, Zoom, Google Meet, Slack, and Skype — great for PC and laptop use. Smof also ships a USB-A/USB-C dongle and adds aptX-LL low-latency encoding for PS4, PS5, and PC, though the dongle isn't meant for Bluetooth mice and keyboards. For console gaming, Smof is the more targeted choice.
