If you want one headset for your own desk that handles calls, webinars and daily office work, choose NUBWO USB Headset; if you need a bulk set of 50 wired earbuds for a classroom, a school or a group of kids, choose Gaosen 50.
These two products get compared a lot, but they solve completely different problems. One is a single work headset with a boom mic and a USB option. The other is a 50-piece classroom pack of colorful earbuds. Let me break down what each one actually does well and which one belongs in your cart.
• NUBWO USB Headset — biggest strength: a unidirectional noise-cancelling boom microphone plus dual 3.5mm/USB connectivity, which makes it a genuine work and call-center tool.
• NUBWO USB Headset — biggest trade-off: it ships as a single unit, so it is not a solution if you need to equip a whole room at once.
• Gaosen 50 — biggest strength: it is a 50-pack. Each earbud is individually bagged and sealed, so distribution to a class is simple.
• Gaosen 50 — biggest trade-off: no microphone and no noise control, so it is purely for listening, not for talking.
• Who each pick is for: NUBWO USB Headset is for the individual professional, student or remote worker who lives on calls. Gaosen 50 is for teachers, schools and anyone buying for a group of kids aged 3–12.
The NUBWO HW02 is built around conversation. Its 40mm drivers, 32ohm impedance and 103dB sensitivity give it the kind of output that works fine straight off a laptop or a desktop USB port. The frequency range runs 20–20000Hz, which is the standard full-range window you would expect from an office headset.
The part that matters most for work is the microphone. It is unidirectional and noise-cancelling, which means it points at your mouth rather than the room, and it is designed to reduce the background noise that ruins calls. If you spend your day on Skype, Zoom, webinars or a call queue, that is the feature doing the heavy lifting. The in-line volume control lets you nudge levels without tabbing away from whatever you are doing, and the on-ear, lightweight plastic build is meant to be worn for long stretches rather than for an hour of music.
Buy it if you are a remote worker, a student in online classes, a receptionist or a call-center agent who needs one dependable headset with a real mic. Skip it if you need to hand out audio gear to a group, or if you only want something for listening to music on the move — the boom mic and the wired desk setup are not built for that.
Gaosen 50: Who It's For
The Gaosen 50 is a different animal entirely. It is a bulk pack of 50 wired in-ear earbuds, model GS01, in mixed colors, and each pair is individually bagged and sealed. That single detail tells you who it is for: anyone who has to distribute headphones to a group and does not want to untangle, sanitize or re-box anything.
The specs are modest and honest. Dynamic drivers, 32 ohm impedance, and a 20Hz–20KHz frequency range — the same basic range as the NUBWO, which is fine for spoken word, videos, testing and study material. The 3.5mm jack works with smartphones, tablets, Chromebooks, computers and laptops, so it slots into almost any school device you already own. There is no microphone and no noise control, so these are strictly for listening.
Comfort is aimed at children. The silicone tips are soft and compact, described as suited to small ears and to students aged 3–12. The brand positions itself around skin-friendly materials and lightweight builds, which is the right priority when the end user is a seven-year-old who will wear them for a 40-minute lesson.
Buy it if you are a teacher, a school, a librarian or a parent organizing a classroom, a testing day, a computer lab or a party favor bag. Skip it if you need to make calls, if you want a full-size over-ear fit, or if you only need one pair — the 50-pack value only makes sense when you actually have 50 people to serve.
• Best for voice calls and meetings → NUBWO USB Headset. The unidirectional noise-cancelling mic and boom arm are the whole point.
• Best for equipping a classroom → Gaosen 50. Fifty sealed pairs in one box beats buying singles every time.
• Best for device flexibility on one desk → NUBWO USB Headset. The 3.5mm plus USB combo covers USB-A laptops, Macs, Chromebooks, tablets and phones.
• Best for young kids → Gaosen 50. Compact silicone tips sized for small ears and an age range of 3–12.
• Best for long work sessions → NUBWO USB Headset. On-ear design, lightweight build and in-line volume control.
• Best for listening only, no talking → Gaosen 50. No mic, no noise control, no fuss.
• Best for hygiene and fast hand-out → Gaosen 50. Each earbud is individually bagged and sealed.
• Best for a single buyer who also games or streams → NUBWO USB Headset. The 40mm drivers and broad compatibility make it the more versatile single purchase.
In my opinion, the right choice comes down to one question: are you buying for yourself or for a group?
If it is for you, I would buy the NUBWO USB Headset. The microphone, the dual 3.5mm/USB connection and the in-line control make it a working tool, not just a pair of headphones. If you are a teacher or a school buyer, I would take the Gaosen 50 without hesitating — 50 sealed, kid-sized earbuds solve a problem no single headset can. Check the current price on Amazon before you commit, since both come in at very different scales.
FAQ
No. The Gaosen 50 is a listening-only earbud pack with no microphone and no noise control. If you need to talk, the NUBWO is the one to pick.
Yes. It ships with a 3.5mm plug and a detachable USB control, so it works with USB-A devices and with anything that has a standard 3.5mm jack, including Chromebooks, tablets and smartphones.
Fifty pairs, in mixed colors, each individually bagged and sealed. That is why it suits classrooms and group hand-outs rather than a single user.
They are not really comparable on value. In my opinion, the NUBWO wins for one person who needs a mic, and the Gaosen 50 wins for anyone buying audio for a whole class. Check the current price on Amazon for both before deciding.
