The yobola T9 rests open in the ear, no tips to size

The yobola T9 is the i12 recipe in its plainest form: two white stems, a rounded bud that sits at the entrance of the ear, and a small flip-top case with one status light. There are no silicone tips to size or lose. You slip a bud in, it rests against the ridge of your ear, and the stem points down toward your jaw.

That open shape is the reason to pick the T9. It suits people who dislike the pressure of a sealed tip, and it leaves you aware of traffic, doorbells and colleagues. The trade-off is bass: a bud that does not seal lets some low end leak out, so a loud bus will compete with your music.

  • Open fit: nothing presses into the ear canal.
  • IPX5: rated against sweat and splashes from any direction.
  • Two microphones with CVC 8.0 noise reduction for calls, per yobola's model chart.
  • Touch controls that include volume, so the phone can stay in a pocket.
  • Up to 5 hours per charge and about 25 hours with the case.

Buds and case together weigh around 40 grams. The shells are ABS and polycarbonate, the hard, glossy plastics used on most stem earbuds, so they wipe clean and survive a tumble onto carpet.

Sound leans toward voices and mid-range detail, which is what an open bud does best. Podcasts, audiobooks and video calls come through clearly, and you can still hear someone say your name across the room. Bass-heavy playlists sound lighter than on a sealed pair, so turn to a tipped model if thumping low end is the priority.

Fit check first: open buds rely on the shape of your outer ear to stay put. If classic stem buds have always slipped out of your ears, a pair with soft tips such as the TAGRY X08 will feel steadier.

Five hours a charge and 25 with the case on the T9

Battery is where the T9 keeps its promises modest. Each bud plays for up to 5 hours, and the case refills them for a total of around 25 hours. That covers a week of commutes and lunchtime playlists before the case needs its own cable.

Your own figures will move with volume and with how many calls you take. Calls keep the microphones and the radio busy, so a day of meetings drains the buds sooner than a day of podcasts.

How you listenWhat to expect
Music at medium volumeClose to 5 hours per charge
Loud music on a noisy trainSomewhat less, because you turn it up
Long phone callsShorter sessions, since the mics work too
Case refills across the weekAbout 25 hours in total

The case has no digit display, only a small light on the front. Make a habit of dropping the buds back in whenever you take them out, and plug the case in when the light warns you. The charging guide explains the light patterns most stem pairs share.

  • Put the buds back in the case between sessions.
  • Charge the case with the included cable once or twice a week.
  • Keep the metal contacts at the bottom of each stem clean and dry.
  • Store the case somewhere cool; a hot car shortens battery life.

Range reaches up to 10 meters, about 33 feet, so the phone can stay on a desk while you walk around a room.

Where this pair lands

i12 TWS earbuds models by fit and case, September 2026. Highlighted: yobola T9.

Pair the yobola T9 and learn its volume taps

Setting up the T9 takes about a minute. Open the case, lift the buds out, and look for the T9 in the Bluetooth menu of your phone, tablet or laptop. After that first pairing, the buds reconnect to the last device whenever you take them out.

  1. Charge the case fully before the first use.
  2. Open the lid and take out both buds; they power on and link to each other.
  3. On an iPhone go to Settings, then Bluetooth; on Android open the Bluetooth quick setting.
  4. Tap the T9 entry once and wait for it to show as connected.
  5. Play a song and check that sound comes from both sides.

If only one bud plays, put both back in the case for a few seconds and try again. The left-right reset steps cover the rare case where a bud keeps playing alone.

The T9 is one of the stem pairs that puts volume on the buds, a function many budget pairs leave out. The exact tap pattern is printed in the manual in the box. The usual layout on i12-style buds runs like this:

  • One tap to play or pause and to answer a call.
  • Double or triple taps for the next track or the voice assistant.
  • Taps on one side to raise the volume and on the other to lower it.

Practise the taps with the buds in your hand first. Because an open bud is not held by a tip, a hard tap can nudge it out of place; a light touch with a fingertip on the flat part of the stem works best. The touch controls cheat card lists the common patterns.

When the T9 fits, and when a newer stem pair suits better

The T9 makes sense for someone who wants the plain white i12 look, an open fit and volume on the buds, and who can live without a digit display or wireless charging. It is a calm, simple pair for podcasts, desk calls and walks.

Line the specs up before you decide, because newer stem pairs push further in a few places:

  • Bluetooth version: the T9's spec sheet gives Bluetooth 4, while yobola's own model chart lists 5.1; many current stem pairs run 5.3 or 5.4.
  • Water rating: IPX5 handles sweat and rain; IPX7 pairs also survive a brief dunk.
  • Battery: about 25 hours in total is modest next to pairs that reach 40 to 60.
  • Case: a status light rather than a battery readout.

If you like the open fit but want more battery and a display, the Jxrev J53 keeps the classic look with Bluetooth 5.4 and IPX7. For the lightest spend on an open pair, the 1 Hora AUT201 keeps things very simple. For a snug fit that blocks street noise, a tipped pair is the better call.

Before ordering, confirm two things: that open buds feel right to you, since the T9 has no tips to change the fit, and that about 5 hours per charge covers your longest listening stretch.

The T9 comes with a charging cable and a 1-year warranty from yobola. Besides white, it is made in black, pink, purple, blue and a light khaki; the colors guide helps if the finish matters to you.

Quick answers

Before these go in your ears

Does the yobola T9 come with ear tips?

No. The T9 is an open-fit stem bud that rests at the entrance of the ear, so there are no tips to size or replace.

Can I change the volume on the T9 buds?

Yes. Volume is one of the touch functions, so you can turn music up or down without your phone. The manual in the box shows which taps do it.

Is the yobola T9 good for the gym?

It is rated IPX5, so sweat and rain are fine. Open buds can shift during jumps and sprints, so for hard workouts a tipped pair holds better.

How long does the T9 battery last?

Up to 5 hours per charge and around 25 hours with the case, depending on volume and how many calls you take.
