Glossy white stems with soft tips, four ENC call mics and Bluetooth 5.4, in a 470mAh case with a tall 1-to-100 display and separate bud gauges.
The XIAOWTEK S58 Pro is a call-minded stem pair. Its glossy white buds share four microphones, and ENC noise reduction uses them to focus on your voice while pushing back steady background sound. On a busy street or in an open-plan office, your caller gets your voice instead of the room.
XIAOWTEK puts the background-noise reduction at around 80 percent. Treat that as a guide: ENC works best on steady sounds such as traffic, fans and chatter, and less on sudden noises or wind gusts.
The soft tips help calls from the other side too. A sealed bud blocks some outside noise, so you hear the caller clearly at a lower volume and do not raise your voice without meaning to.
Fit is the other half of good calls. Try the tips in each size until the bud sits flush without pressure; a loose bud lets outside noise in and makes the caller sound thin.
The design is the classic i12-style stem, updated: a slim glossy stem with a small blue light at the top, a rounded head with a soft tip, and a pebble-shaped white case with a tall display window. Five colours are made, white, black, dark black, green and pink, so a work pair and a gym pair can look different. The colors guide compares finishes.

The S58 Pro case holds a 470mAh battery and shows its level as a number that counts from 1 to 100 while charging, with separate gauges for the left and right buds. Each bud plays for about 6 hours per charge, and the case refills both buds about four times.
The headline 50 hours counts using the buds in turn, one at a time. With both buds playing together, the maths gives about 30 hours: 6 hours from the first charge plus four refills. That is still a week of commutes for most people, and single-bud listening on calls stretches it further.
| How you listen | What to expect |
|---|---|
| Both buds, one charge | About 6 hours |
| Both buds, with case refills | About 30 hours |
| One bud at a time, swapping | Up to 50 hours in total |
| Loud music or long calls | Somewhat less than the figures above |
Putting the buds in the case starts charging straight away, and the display shows it happening. A few habits help:
The display also tells you when the case itself is charging: plug in the USB cable and the number starts to climb toward 100. The charging guide explains display cases and what to do if one gauge will not rise.
A Hall switch is a small magnetic sensor that knows when the lid opens. On the S58 Pro, it wakes the buds and reconnects them to your last device the moment you flip the case open, so a normal day starts with no tapping on the phone at all.
The S58 Pro works with Android 4.4 and iOS 8.0 or newer, and with any device running Bluetooth 4.0 or later, which covers old tablets and laptops too. The pairing guide covers laptops, and the reset steps fix a bud that stays silent.
Bluetooth 5.4 keeps the link steady up to 15 meters, with low latency that keeps sound in step with games and videos. AAC is supported, the codec iPhones use for Bluetooth audio, along with SBC for everything else.
If the buds ever stop reconnecting on their own, the fix is nearly always the same: forget the S58 Pro in your phone's Bluetooth list, put both buds back in the case for a few seconds, then pair from scratch as above.
The touch sensor is precise, designed to cut down on accidental taps when you adjust the fit. It controls:
The manual in the box shows the exact tap counts, and the touch controls cheat card lists common patterns.
The S58 Pro suits someone who takes a lot of calls, wants a proper numeric battery display and needs a water rating that handles rain and sweat. The 13mm triple-layer drivers with a polymer diaphragm give a full bass that blends naturally into the mids and highs.
Points to weigh before choosing:
XIAOWTEK makes several close relatives. The XIAOWTEK S66 and the XIAOWTEK A66 both run Bluetooth 5.4 with ENC mics, 13.4mm drivers, IPX7 and up to 50 hours. For wireless charging and a digit display, the TAGRY X08 reaches up to 60 hours.
The ergonomic in-ear shape keeps the buds steady through a gym routine, and a nano coating on the buds is what earns the IPX7 rating. Wipe them down after training, and they will handle daily sweat for a long time.
In the box are two earbuds, the charging case, a USB cable and a user manual, backed by a 1-year warranty from XIAOWTEK. Charge it to 100, pair it once, and the Hall-switch lid handles every reconnection after that.
About 6 hours per charge. The 470mAh case refills both buds about four times; the 50-hour total counts using one bud at a time.
The buds are rated IPX7 for sweat, rain and splashes. Keep the charging case dry.
Yes. It supports AAC and works with iOS 8.0 or newer, as well as Android 4.4 or newer.
