• Delton Headset biggest strength: Purpose-built for Microsoft Teams with answer/end call support, plus a charging case that pushes total talk time to 108 hours.
• Delton Headset biggest trade-off: It's an in-ear bud design with a 13mm driver, so it's less about big on-ear comfort and more about a compact, pocketable setup.
• NANSLS Headset biggest strength: Dual-device Bluetooth connection and a 270° rotatable mic on a lightweight 139g on-ear frame.
• NANSLS Headset biggest trade-off: No charging case and no dedicated dongle — it's a straight Bluetooth headset, so it leans on its own 60-hour battery.
• Pick Delton Headset if you live inside Teams, Zoom, and Google Meet and want a case that keeps you going for days.
• Pick NANSLS Headset if you split calls between a phone and a laptop and want one lightweight headset for both.
The Delton 95X is clearly aimed at the person whose workday runs through meeting software. The headline feature is native Microsoft Teams integration — you can answer and end calls without fiddling with your phone — and it also plays nicely with Google Meet, Zoom, Slack, and Skype. If your calendar is a wall of video calls, that platform-first design matters more than raw audio specs.
Battery is the other big story. The earpiece itself is rated for 18 hours of talk time, and the charging case adds another 90 hours, for a combined 108 hours. In practice that means you can leave the charger at home for a multi-day stretch and still take calls. A 3-hour charge tops it up, and you can power it either through the case or a USB-C cable — two-way charging that suits people who move between a desk and a bag.
Who should buy it: remote workers, support staff, and anyone whose employer standardizes on Teams. Who should skip it: if you want an on-ear headband you can wear loose all day, or you need to stay connected to two devices simultaneously — Delton's sheet doesn't list dual-device pairing, so don't count on it.
NANSLS Headset: Who It's For
The NANSLS M100 is a single-ear on-ear headset built for people who are on the phone constantly but don't want a bulky rig. It's light — 139g — with an adjustable headband, a soft ear cushion, and a 270° rotatable mic you can swing to either side. That's a trucker-friendly, call-center-friendly shape: you wear it for hours, and you can still hear what's going on around you.
The feature I'd point to first is dual-device connection. The headset can hold onto two Bluetooth devices at once — say your phone and your laptop — so a call can come in while you're still tethered to your computer. That's the single most useful thing here for anyone who juggles a desk and a mobile line.
Battery follows the same "get through the day" logic: 45 hours of talk time, 60 hours of music playback, and 90 hours of standby, all from a 2-hour charge on a 400mAh battery. For noise, it uses ENC, which the spec claims reduces up to 98% of background noise on your voice — the kind of thing that matters in a cab, a warehouse, or a busy office.
Controls are generous: answer, reject, mute, volume, redial, skip tracks, and voice assistant, via buttons and touch, with one-touch mute for privacy. Connectivity is Bluetooth only — no dongle, no case — with a 33-foot range.
Who should buy it: drivers, call-center agents, and remote workers who want a light on-ear headset and dual-device pairing. Who should skip it: if you need a charging case, a USB dongle for a locked-down work laptop, or a stereo in-ear fit, this isn't that product.
Side-by-Side: Which Should You Choose?
• Best for battery endurance → Delton Headset. 18 hours in the earpiece plus 90 hours from the case equals 108 hours of talk time; NANSLS tops out at 45 hours of talk time.
• Best for dual-device use → NANSLS Headset. It connects to two Bluetooth devices at once; Delton's sheet lists Bluetooth plus a USB dongle but no simultaneous two-device pairing.
• Best for all-day on-ear comfort → NANSLS Headset. A 139g on-ear frame with an adjustable headband and 270° mic is easier to wear loose for a full shift than an in-ear bud.
• Best for a compact, travel-friendly setup → Delton Headset. The charging case and in-ear design pack down small and recharge on the go.
• Best for noisy-environment voice pickup → a close call. Both use noise-reduction tech on the mic (Delton via DSP, NANSLS via ENC), so pick based on fit and connection style rather than assuming one is dramatically better.
• Best for connecting to a work laptop without Bluetooth hassle → Delton Headset. The included USB dongle sidesteps Bluetooth pairing quirks on locked-down machines.
• Best for simple, no-extra-parts ownership → NANSLS Headset. One headset, one Type-C cable, one manual.
If I'm buying for myself and my day is mostly video meetings on a work laptop, I'd take the Delton Headset. The Teams integration, the USB dongle, and that 108-hour combined talk time solve the three things that annoy me most about office headsets: pairing fights, dead batteries, and fumbling to answer calls.
If instead my calls happen on the move — split between a phone and a computer, with long stretches of wear — I'd take the NANSLS Headset. The dual-device connection and light on-ear fit are exactly what that job needs. Both are solid picks; the deciding factor is whether your work lives in an app or on the road.
By the numbers, Delton: 18 hours of talk time in the earpiece, extended to 108 hours total with the charging case. NANSLS offers 45 hours of talk time, 60 hours of music, and 90 hours of standby on a single 2-hour charge. Delton wins on total endurance thanks to the case.
Yes. It supports dual-device Bluetooth connection, so you can stay linked to two devices — for example a computer and a phone — and switch between them for calls.
It's designed primarily for Microsoft Teams, including answer and end call control, but it also works with Google Meet, Zoom, Slack, and Skype.
The Delton Headset includes both a charging case and a USB dongle, and can charge via the case or a USB-C cable. The NANSLS Headset is Bluetooth-only with a Type-C charging cable and no case or dongle. If you want a case or dongle, go Delton. Check the current price on Amazon before you decide.
