Two full U38 sets, one white and one blue

The FEFURS U38 comes as a pair of pairs: two complete stem-earbud sets in one box, each with its own charging case. One set is white, the other blue, so siblings can tell theirs apart without a name label. Both run on Bluetooth 5.4 and wear soft silicone tips shaped for smaller ears.

Buying two identical-spec sets at once solves a common family problem. Nobody argues over whose turn it is, and when one pair is left at a friend's house, the other still works.

What each U38 set includes:

  • Two buds and a charging case. The case refills the buds whenever they rest inside it.
  • Soft silicone tips. They sit inside the ear canal and grip, so the buds stay put on a playground or a bike.
  • Touch controls. Taps on the stems play and pause music, answer calls and wake Siri or Google Assistant.
  • Bluetooth 5.4. A steady link up to 15 metres, so a tablet on the desk keeps playing while a child wanders the room.
Color-coding is the quiet win here. White goes to one child, blue to the other, and the cases stay matched to the buds that belong in them.

At 4.3 grams per bud, by the maker's figure, the U38 is light for its size, and the rounded stems avoid sharp edges. The age guide covers 8 to 10, teens and grown-ups, so a parent can borrow the second set for a work call.

There is no LED readout on the case, just the plain charging case. That keeps things simple, though it means checking the battery on the phone or tablet, where many devices show the buds' charge once they're connected.

10mm drivers and 5 to 6 hours for school days and road trips

Each U38 bud holds a 10mm dynamic driver covering 20Hz to 20kHz, the full range people hear. That is a smaller driver than the 13mm and 14.2mm units in adult stem earbuds, and it suits the job: clear voices for lessons and audiobooks, with enough bass to make music fun.

Battery life is built around a school day rather than a long-haul flight. The buds play 5 to 6 hours on a charge, and the case refills them in about an hour. Left unused, a charged set can sit on standby for up to 300 hours.

Where two U38 sets earn their keep:

  • Online classes and homework videos on a laptop or tablet.
  • Back-seat road trips, with one film on each device and no shared sound.
  • Audiobooks at bedtime, where soft tips feel kinder than hard plastic.
  • Games on a handheld or phone, with the buds paired straight to the device.
Everyday taskHow the U38 handles it
A full school day of on-and-off use5 to 6 hours per charge, then back in the case
A dead bud before the busAbout an hour in the case refills it
A week in a drawerUp to 300 hours of standby
A call with grandparentsBuilt-in mic and tap to answer

No water rating is listed for the U38. Treat the buds as indoor and everyday gear: wipe off sweat after gym class, keep them away from the pool and dry the case if it gets splashed.

Among the pairs

Where this pair lands

i12 TWS earbuds models by fit and case, September 2026. Highlighted: FEFURS U38 Kids 2-Pack.

Set a volume limit before the U38 goes to a child

Pairing the U38 takes seconds: take the buds out of the case and they link to each other and show up in the device's Bluetooth menu. Before handing a set over, though, spend two minutes on the device's sound settings, since the maker doesn't list a built-in volume cap.

  1. Charge both cases fully so the first session doesn't end halfway.
  2. Take the white buds out and pair them with the first child's tablet or phone.
  3. Close that case, then pair the blue buds with the second device, so the sets don't cross over.
  4. Turn on a volume limit on each device before the first listen.

Apple devices have a Headphone Safety setting that trims loud audio down to a level you pick. Many Android phones and tablets have a media volume limiter in their sound settings, and family-control apps can lock it in place.

Pair each set to one device and leave it there. Buds remember the last device they joined, so a set that hops between tablets can end up connecting to the wrong child's screen.

Fit checks for small ears:

  • The stem should point down toward the jaw, not forward.
  • A good fit feels snug but never pushes; if it pinches after ten minutes, reseat it with a gentle twist.
  • Clean the tips weekly with a dry cloth, since ear wax blocks sound fast on small buds.

Taps on the stems handle music, calls and the assistant; the touch controls cheat card maps them out. If one side goes quiet, the left and right reset relinks the pair in a minute.

U38 two-pack against single kids' pairs

A two-pack isn't the right call for every family. If only one child needs earbuds, a single pair with more battery or a water rating may serve better, so here is how the U38 compares with a few other stem pairs that suit young listeners.

PairSetsBluetoothBatteryWater
FEFURS U3825.45 to 6h a chargeNot listed
Awaiymi Kids Earbuds15.036h with caseIPX4
MIPOW Miffy TD1715.330h with caseIPX5
TAGRY X0815.x60h with caseIPX5

Choose the U38 if:

  • Two children need earbuds at the same time.
  • Color-coded sets would end the daily mix-ups.
  • You want the newest Bluetooth 5.4 in a small, light bud.

Look elsewhere if one child plays sports in the rain, where the Awaiymi Kids Earbuds add an IPX4 rating, or if a cute gift matters more than a second set, where the Miffy case steals the show. A teen who wants long battery and a digit readout will be happier with the TAGRY X08.

A quick family checklist first:

  • Each device the sets will pair with has Bluetooth; any version works.
  • You can live without a battery display on the case.
  • The children are 8 or older, per the maker's age guide.

For more ideas on shades and case finishes, the colors guide shows the pairs in each look. And if the budget is set per child, the price bands show what a single pair costs next to this two-set box, so you can weigh one box of two against two separate pairs bought one at a time.

Quick answers

Before these go in your ears

Are there really two full sets in the FEFURS U38 box?

Yes. You get two complete sets, each with its own buds and charging case: one white, one blue.

What ages is the U38 made for?

The maker sizes it for ages 8 to 10, teens and adults. The soft silicone tips suit smaller ear canals.

Does the U38 limit the volume?

No volume cap is listed, so set one on the device. iPhones and iPads have Headphone Safety, and many Android devices offer a media volume limiter.

How long does a U38 charge last?

About 5 to 6 hours of listening per charge, and the case refills the buds in around an hour.

Can the two U38 sets pair to the same tablet?

Pair each set to its own device for the smoothest use. Most tablets play to one pair of earbuds at a time.
