Most vivo Buds Ultra problems can be fixed without replacing the earbuds. Start by forgetting the old Bluetooth record, reseating both earbuds in a clean, dry charging case, charging briefly, and pairing again. That sequence addresses stale pairing data, poor charging contact, and a lost stereo link. If one side remains silent after those checks, test phone balance settings and a second device before seeking service. The case supports USB-C and wireless charging, while the earbuds are IP54-rated; neither fact means the case is waterproof or that battery figures are guaranteed in every use.
What should I check first when vivo Buds Ultra stop working?
Match the symptom to the least destructive remedy. Re-seating, cleaning and re-pairing are reversible; a factory reset erases saved pairing information and should wait until you confirm the procedure for your exact regional model. Work in a quiet, dry place so you can hear connection prompts and avoid introducing moisture while cleaning.

Do not jump directly to replacement because the phone reports a low or missing earbud. The case can detect that an earbud is physically present even when dirt, oxidation or a poor fit prevents electrical charging. A short, deliberate sequence—case power, clean contacts, both earbuds together, then a fresh pairing—separates a simple setup problem from a likely hardware fault.
How do I fix vivo Buds Ultra that will not connect?
Rebuild the Bluetooth relationship from scratch. The steps below clear the most common stale-host and incomplete-pairing states without assuming that a model-specific reset is available.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Bring everything together. Keep the phone and charging case close to each other. Turn the phone’s Bluetooth off, wait briefly, and turn it back on. Avoid trying to pair through walls or while the case is across the room.
- Remove the old record. Open the phone’s Bluetooth settings, select the saved vivo Buds Ultra entry and choose Forget, Unpair or Remove device, depending on the operating system. If several Buds Ultra entries are listed, remove each old or duplicate record.
- Prepare both earbuds. Put both earbuds into their molded case slots and confirm that each is fully seated. Open the lid while the case is next to the phone. A loose earbud may not enter the same pairing state as its mate.
- Start a fresh pairing. On a supported vivo or iQOO phone, use the Bluetooth device panel or Connectivity Center. On another Android phone or an iPhone, use the normal Bluetooth pairing flow and install the vEarphones app when vivo requires it for supported features.
- Eliminate competing hosts. If a tablet or another phone is connected, disconnect it before trying the intended phone. Buds Ultra can switch among up to three devices, but an old host can still hold control at the wrong moment.
- Restart once if needed. Restart the phone and repeat the forget-and-pair process if the earbuds still do not appear or connect. Keep the case open and both earbuds seated during the discovery attempt.
After a successful connection, test a short song and a phone call rather than assuming the process is complete. If music works but calls do not, check the phone’s selected Bluetooth input and output separately. If the earbuds disappear whenever another device wakes, temporarily disable Bluetooth on that device, then reconnect hosts one at a time.
Do not substitute a reset procedure copied from a different vivo earbud model. The public Buds Ultra product information does not publish a dedicated model-specific reset sequence, so a button combination from another model may do nothing or produce a different result.

Compatibility and multi-device management differ by phone and operating system. Buds Ultra supports connections to up to three devices, while management of that feature requires Android 13 or later or iOS 14.0 or later. Some controls are limited to compatible vivo or iQOO phones. A phone can therefore provide basic stereo audio while lacking a particular switching or management control.
Using a vivo or iQOO phone
Open the Bluetooth device panel or Connectivity Center with the case open and both earbuds seated. If the phone offers a Buds Ultra card, use that card to connect and manage the earbuds rather than repeatedly tapping an old Bluetooth entry. Install pending system updates if the card or advanced controls do not appear, then repeat the forget-and-pair procedure.
Using another Android phone or an iPhone
Pair from the operating system’s Bluetooth settings after forgetting any previous Buds Ultra record. vivo says the vEarphones app is required on non-vivo/iQOO phones for supported advanced features; actual behavior depends on phone compatibility. Basic audio may work even when a particular management feature does not. The app cannot compensate for a phone that does not meet the required operating-system version.
When several devices are nearby
Temporarily switch Bluetooth off on the other paired devices or disconnect Buds Ultra from them. Once the intended phone has control, reconnect the other devices one at a time so you can identify which host is interrupting the connection. This is more reliable than repeatedly tapping Connect on several screens at once.
How do I fix one vivo Buds Ultra earbud that is not charging?
Both earbuds must make clean, dry contact with the case before you diagnose a dead side. A partially seated earbud can look present while its battery receives no charge.

- Remove both earbuds and inspect the left and right molded slots for lint or debris. Check that no piece of the ear tip or pocket lint prevents an earbud from sitting flush.
- Place each earbud back into its matching slot. Press gently until it sits flush and the case acknowledges it. Do not force an earbud at an angle.
- Inspect the metal contacts in the case and the charging pads on the earbud. Clean them only with a dry, lint-free cloth or dry cotton swab.
- Keep liquid away from the openings and contacts. Do not scrape the pads with a sharp object or use alcohol, water or household cleaner.
- Charge the case by USB-C if its battery is low. Leave both earbuds in the case for a short period before testing audio again. A depleted case cannot reliably recharge an otherwise healthy earbud.
- Remove both earbuds together and play stereo audio. Testing them as a pair helps the phone rebuild the left-right connection.
If the case still does not acknowledge one earbud after dry cleaning and charging, move to the one-ear diagnostic steps below. Continued failure after those checks indicates a contact, battery or internal hardware problem that needs official service. Note which side fails and whether the failure follows the earbud when you swap phones; that detail helps service staff.
Can I charge the vivo Buds Ultra case wirelessly?
Yes. The case supports wireless charging as well as USB-C cable charging. vivo states that a wireless charger is not included as standard equipment, so wireless charging requires a separate compatible charging pad. There is no need to buy a pad if cable charging is convenient.
USB-C charging
Connect a suitable USB-C cable to the case and allow the case battery to recover before judging an earbud fault. A low case battery can prevent the contacts from supplying meaningful charge even when the earbuds are seated correctly. If the cable connection is loose, try a known-good cable and power source; stop using the case if it becomes unusually hot or shows physical damage.

Center the case on a compatible wireless charging pad and verify that the pad indicates charging. Remove thick or misaligned accessories that prevent the case from sitting flat. If wireless charging is intermittent, use USB-C to separate a pad-alignment issue from a case-battery issue. The optional pad is an accessory cost to plan for, not an item vivo promises in the standard Buds Ultra package.
Why is only one vivo Buds Ultra earbud playing audio?
A silent side is often caused by incomplete charging or a broken stereo pairing record, but blocked sound output and phone accessibility settings can produce the same symptom. Work through these checks in order.
- Reseat both sides. Return both earbuds to the case and confirm that each makes charging contact.
- Give them a short charge. Leave them in the case, then remove both at the same time and test stereo playback.
- Rebuild pairing. Forget the vivo Buds Ultra Bluetooth entry and pair again with both earbuds together.
- Inspect the silent outlet. Look for earwax or debris over the speaker grille. Clean gently with a dry, non-sharp tool; never push anything into the grille or add liquid.
- Check phone audio controls. Confirm that left-right balance is centered and that an accessibility setting has not routed all audio to one channel. Also verify that mono-audio or a per-app volume control is not enabled.
- Change the test. Try another app and, if possible, another phone. If the side works elsewhere, the original phone or app is the likely cause.
When one side remains silent after charging, cleaning and re-pairing, treat it as a possible hardware fault. Use the reset guidance in the next section only after verifying the exact regional model instructions. Do not keep increasing volume to compensate for a blocked grille; that can make the working side uncomfortably loud without fixing the silent side.

An official vivo TWS support FAQ for a TWS Earphone model says to put both earbuds in the open case and hold the case function key for 15 seconds until the orange light flashes rapidly. The same FAQ describes holding the key for five seconds to pair a replacement earbud with an existing one. Those instructions are evidence for that named TWS family, not confirmation that every Buds Ultra regional version uses the same sequence.
- Check the manual or support page for your exact regional Buds Ultra model and hardware revision.
- If the manual confirms a reset, remove the old Bluetooth entry from every phone first.
- Follow the published button timing exactly, then pair the earbuds as a new device.
- If no Buds Ultra-specific instruction is available, contact an official vivo service center rather than experimenting with a different model’s sequence.
A reset is not a charging repair and will not restore a physically damaged contact, wet case or exhausted battery. It is most useful after the reversible checks have ruled out seating, debris, competing hosts and phone settings.
What battery life should vivo Buds Ultra deliver?
vivo’s laboratory figures are 50 hours of total music playback with the case, 11 hours on a single charge, and two hours of playback from a five-minute charge. These are reference measurements, not guarantees.
| Claim | Condition attached to the figure | Why your result may differ |
|---|---|---|
| 50 hours with case | vivo laboratory measurement using MP3 looping, AAC, 50% volume, ANC off and controlled room temperature. | ANC use, codec, volume, temperature, software and battery aging reduce runtime. |
| 11 hours per charge | Same stated laboratory setup. | Real listening patterns and call time are different from continuous MP3 playback. |
| 2 hours from a 5-minute charge | Short-charge laboratory result under the same conditions. | The result varies with battery condition, temperature and charging behavior. |
Use the figures to spot an unusually rapid drain, not to predict an exact daily schedule. ANC, a different Bluetooth codec, high volume, cold or hot conditions, calls and an aging battery all change the result. If one earbud consistently empties much faster than the other after clean contacts and a fresh pairing, record the difference and provide it to service support.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Is vivo Buds Ultra waterproof?
The earbuds are rated IP54 under IEC 60529. That rating applies to the earphones only, not the charging case, and the protection is not permanent; normal wear can reduce it.
Dry the earbuds and all contacts completely before putting them back in the case. Do not charge wet earbuds, rinse the case, or treat IP54 as protection against immersion, showers or sustained water exposure. If audio or charging remains abnormal after liquid contact, stop testing and arrange service. Sweat, rain and dust exposure should be followed by wiping and complete drying, not immediate case charging.
When should I contact vivo service?
Escalate after you have completed the reversible checks: clean and dry contacts, charged the case, reseated both earbuds, forgotten the Bluetooth record and paired again. Service is appropriate when:

- One earbud is never acknowledged by the case.
- A side remains silent across multiple apps and a second phone.
- The case will not charge by USB-C and wireless charging also fails.
- Problems began after liquid exposure or physical impact.
- The earbuds repeatedly lose connection after a clean pairing on compatible devices.
- You need a replacement earbud and cannot verify a model-specific pairing procedure.
Have the purchase information, phone model, operating-system version, region and a description of the steps already attempted ready for the support representative. Note whether the issue affects one side, both sides or only a particular host. Replacement availability and pricing vary by region and are not established by the public Buds Ultra pages referenced here, so confirm any quote directly with vivo before ordering an individual earbud or a complete set.
How can I prevent these problems?
- Keep both earbuds in their case when not in use so each side remains charged.
- Wipe contacts with a dry lint-free cloth instead of using liquid cleaners.
- Keep the case away from moisture even though the earbuds have an IP54 rating.
- Disconnect unused hosts when switching among several phones, tablets or computers.
- Keep the phone’s operating system and the vEarphones app current when using supported advanced features.
- Use the charging method that is most reliable for your setup; wireless charging is optional, while USB-C is the fallback.
- Store the case with its lid closed and avoid placing loose metal objects against charging contacts.
Quick decision guide: which remedy is safest?
For a connection-only problem, forget and re-pair before considering any reset. For a charging problem, inspect and dry the contacts, then charge the case by USB-C; use a wireless pad only as an optional alternative. For one-ear audio, charge and remove both earbuds together, rebuild pairing, check balance and test another device. For liquid or impact damage, drying and service are safer than repeated charging attempts. This order preserves your settings, avoids unnecessary accessory purchases and gives support a clear record of what has already been tried.
Frequently Asked Questions
Will vivo Buds Ultra work without the vEarphones app?
Basic Bluetooth audio can be available through the phone’s normal pairing settings, but vivo says supported advanced features on non-vivo/iQOO phones require the vEarphones app. Which controls appear depends on the phone and operating-system compatibility.
Can I use a different USB-C charger for the Buds Ultra case?
The official guidance establishes USB-C case charging but does not specify a special bundled charger requirement. Use a sound, compatible USB-C charging setup and stop if the case becomes unusually hot or shows physical damage.
Why does the case show an earbud as present but its battery never rises?
Presence detection does not prove that the charging pads are making an electrical connection. Remove the earbud, dry-clean both contact surfaces, reseat it flush, and charge the case before testing again.

Should I reset the earbuds before sending them for repair?
Not unless the exact regional Buds Ultra manual confirms the reset sequence. Forgetting the Bluetooth entry on your phones is safe; an unverified hardware-button procedure can leave you with an unresolved fault and erased pairing data.
How many devices can vivo Buds Ultra remember or switch between?
vivo states that Buds Ultra can connect to up to three devices in Bluetooth mode. Multi-device management requires Android 13 or later or iOS 14.0 or later, and some controls depend on a compatible vivo or iQOO phone.

Is a wireless charging pad included with vivo Buds Ultra?
No. vivo confirms wireless charging support but says the wireless charger is not included as standard equipment. USB-C charging remains the straightforward fallback.
Can I charge the case while the earbuds are inside?
The case is designed to charge by USB-C or a compatible wireless pad while the earbuds sit in their molded slots. Keep the contacts dry and correctly seated, and verify charging before diagnosing an earbud.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesDoes IP54 protect the charging case?
No. The IP54 rating applies to the earphones only, under IEC 60529, and protection can decline with wear. Keep the case dry and allow wet earbuds to dry fully before insertion.
Why does one earbud drain faster than the other?
Differences in use, calls, radio conditions and battery age can create unequal drain. First clean and reseat both earbuds, charge the case, pair again and compare results on a second device; persistent extreme imbalance warrants service.
Where can I find replacement-earbud pricing?
The public Buds Ultra information does not establish regional replacement prices or availability. Ask an official vivo service center for a current quote and verify the exact regional model before buying a replacement side.
The Bottom Line
Forget the old Bluetooth record, clean and dry both charging paths, charge the case, and pair both vivo Buds Ultra earbuds together before attempting a reset. USB-C is included as the practical charging route; wireless charging is supported but requires a separate pad. Remember that the 50-hour, 11-hour and five-minute claims are laboratory figures, IP54 covers only the earbuds, and unresolved one-sided, charging or liquid-related faults belong with an official vivo service center.
