White open-fit stem earbuds on Bluetooth 5.0, with dual mics and CVC 8.0 noise reduction for calls, 10mm drivers, an IPX5 rating and 28 hours in total with the case.
The SGNICS TWS 5.0 is a white open-fit stem earbud in the classic shape: a smooth head that rests in the outer ear, a straight stem pointing down, and no silicone tips. It connects over Bluetooth 5.0 and reconnects to the last device it paired with as soon as you take it out.
The appeal is simple. Open-fit buds put no pressure inside the ear canal, so they stay comfortable through long calls and let you hear what's going on around you. There are no tips to size, wash or lose, either.
What the SGNICS offers:
SGNICS names the OnePlus Nord N100 in its title, but that's just one of many phones it suits. The maker lists iPhones from the 11 to the 14 series, Samsung Galaxy S20 to S23 and Note models, and Google Pixel 6 and 7. In practice, any phone, tablet or laptop with Bluetooth will pair with it.
Bluetooth 5.0 is an older version than the 5.3 and 5.4 radios in newer pairs. It still gives a stable link for everyday listening, and the maker highlights ultra-low latency for videos. For how the generations compare, the specs and sound overview lays out what each version brings.

The SGNICS plays up to 4 hours on a charge, and the case adds another 24, for 28 hours in total. That pattern suits people who listen in stretches: a commute, a workout, an afternoon of calls, then back in the case.
Four hours per charge is on the short side next to newer 8-hour buds, so the case does a lot of the work. Each time the buds go back in, they top up from the case battery, and the case itself charges over a USB-C cable.
| Moment | How the SGNICS handles it |
|---|---|
| Commute there and back | One charge each way, with a top-up in between |
| A long afternoon of calls | Swap buds, or rest them in the case between calls |
| A week of short sessions | Up to 28 hours from a full case |
| A sweaty gym visit | Well inside one charge, covered by IPX5 |
There's no battery readout on the case, so a simple routine helps:
Real hours depend on volume and how much time you spend on calls. Keeping the volume moderate gets you closest to the full 4 hours per charge. With open-fit buds, it also helps to listen in quieter spots when you can, since a noisy street tempts you to turn things up and drain the buds faster.
For what the case lights mean and how to fix a bud that stops charging, see the charging guide.
Single-bud use is one of the handiest SGNICS tricks. Either earbud can work alone, so you can take a call with one while the other rests in the case, which effectively stretches a day of calls well past 4 hours.
After the first pairing, the buds reconnect to the last device automatically when they leave the case. The pairing guide covers iPhone, Android and laptops, and the left and right reset helps if the two buds stop talking to each other.
The touch panel on each bud handles the daily jobs:
The touch controls cheat card maps the common tap patterns for stem earbuds.
Mono mode also suits drivers and cyclists who want one ear free, though local rules on earbuds while driving or riding vary, so check them before you head out.
IPX5 means sweat and light splashes are fine. Wipe the buds after exercise and let them dry before they go back into the case, so moisture stays away from the charging contacts.
The SGNICS is a straightforward open-fit pair on an older Bluetooth version. Newer stem pairs add longer battery and fresher radios, so here's how it compares with three of them.
| Spec | SGNICS TWS 5.0 | XIAOWTEK A40 Pro | 1 Hora AUT201 | Jxrev J53 |
|---|---|---|---|---|
| Bluetooth | 5.0 | 5.3 | 5.3 | 5.4 |
| With case | 28h | 50h | 22h | 40h |
| Water | IPX5 | IPX7 | Not listed | IPX7 |
| Case | Plain | Plain | Plain | LED digits |
| Driver | 10mm | 12mm | Not listed | 13mm |
Choose the SGNICS if:
The XIAOWTEK A40 Pro nearly doubles the total battery and adds IPX7 in a half in-ear shape with soft caps. The 1 Hora AUT201 is the simple budget open pair on Bluetooth 5.3, and the Jxrev J53 brings an LED case and ENC mics.
Before ordering, confirm that:
For a sense of how open-fit pairs spread across budgets, the price bands lay out what every step up adds.
The SGNICS makes the most sense for someone who wants the familiar white stems for calls and everyday listening, and who likes the flexibility of one bud at a time. Anyone who listens for hours without a break, or who wants to watch battery digits on the case, will be happier with the A40 Pro or the J53.
No. The N100 is just named in its title. It pairs with any Bluetooth phone, including iPhones, Samsung Galaxy and Google Pixel models.
Up to 4 hours per charge, and the case adds 24 hours for 28 hours in total.
Yes. Either bud works on its own, so you can take calls with one while the other charges.
It's rated IPX5, which covers sweat and splashes. Keep it out of heavy rain, showers and pools.
No. CVC 8.0 is call noise reduction that cleans up your voice; the open fit lets outside sound in.
