The idea is being tested, but the most directly relevant study is a registered randomized-trial protocol rather than a completed efficacy report. Patients should not use headphones as a substitute for an anesthetist’s or surgeon’s anti-nausea plan.
What the current evidence actually shows
The strongest study identified for this specific question is a protocol for a single-center, prospective randomized trial in adults having gynecologic laparoscopic surgery. It plans to enroll 192 participants. One group will wear noise-cancelling headphones from induction of anesthesia until the end of surgery; the control group will not wear headphones.

Because the trial protocol does not report final randomized results, it cannot establish that headphones reduce nausea or vomiting. The protocol itself states that direct evidence for noise-cancelling headphones reducing PONV is currently lacking.

The preliminary percentages are not trial results
Planning observations cited in the protocol found PONV in 21.74% of a headphone group and 47.83% of a control group. Those figures were used to plan the sample size. They are not the final outcomes of the randomized trial, and they should not be presented as proof that headphones work.
#1 Best Overall
- Hybrid Active Noise Cancelling: 2 internal and 2 external mics work in tandem to detect external noise and effectively reduce up to 90% of it, no matter in trains or offices.
- Immerse Yourself in Detailed Audio: The noise cancelling headphones have oversized 40mm dynamic drivers that produce detailed sound and thumping beats with BassUp technology for your every travel, commuting and gaming. Compatible with Hi-Res certified audio via the AUX cable for more detail.
- 40-Hour Long Battery Life and Fast Charging: With 40 hours of battery life with ANC on and 60 hours in normal mode, you can commute in peace with your Bluetooth headphones without thinking about recharging. Fast charge for 5 mins to get an extra 4 hours of music listening for daily users.
- Dual-Connections: Connect to two devices simultaneously with Bluetooth 5.0 and instantly switch between them. Whether you're working on your laptop, or need to take a phone call, audio from your Bluetooth headphones will automatically play from the device you need to hear from.
- App for EQ Customization: Download the soundcore app to tailor your sound using the customizable EQ, with 22 presets, or adjust it yourself. You can also switch between 3 modes: ANC, Normal, and Transparency, and relax with white noise.
What the planned trial will measure
The primary outcome is nausea and vomiting during the first 48 hours after surgery. Researchers also plan to record outcomes that could clarify whether any effect is clinically useful or limited to comfort:
- Severity of nausea and vomiting
- Use of rescue antiemetic medicines
- Postoperative pain and opioid-related outcomes
- Quality of recovery and sleep
- Length of hospital stay
- Adverse events and patient satisfaction
Testing headphones from anesthesia induction through the operation is important because it differs from simply listening to music or using headphones in the recovery room. The intervention is intended to reduce exposure to operating-room sounds throughout anesthesia, not just to distract a patient after nausea begins.
Rank #2
- Block the World, Keep the Music: Four built-in mics work together to filter out background noise — whether you're in a packed office, on a crowded commute, or moving through a busy street — so every beat comes through clean and clear. (Not available in AUX-in mode.)
- Two Ways to Hear More: BassUp technology delivers deep, punchy bass and crisp highs in wireless mode — then step it up further by plugging in the included AUX cable to unlock Hi‑Res certified audio for studio-level clarity.
- 40 Hours. 5-Minute Top-Up: With ANC on, a single charge keeps you listening through days of commutes and long-haul flights. Running low? Just 5 minutes plugged in gives you 4 more hours — so you're never stuck waiting.
- Two Devices, Zero Hassle: Stay connected to your laptop and phone at the same time. Audio switches automatically to whichever device needs you — so a call never interrupts your flow, and getting back to your playlist is just as easy. Designed for commuters and remote workers who move smoothly between work and personal listening throughout the day.
- Your Sound, Your Rules: The soundcore app puts everything at your fingertips — dials your ideal EQ with presets or build your own, flip between ANC, Normal, and Transparency modes on the fly, or wind down with built-in white noise. One app, total control.
How broader research changes the picture
Evidence on sound and other non-drug approaches is mixed. A systematic review of auditory stimuli during general anesthesia included 16 studies that assessed PONV, but differences in outcome definitions and reporting prevented a meta-analysis. That means the studies could not be combined into a reliable overall estimate.

It reported low or very low certainty for most comparisons and did not establish noise-cancelling headphones as effective for preventing PONV. Low-certainty evidence means that future, better-designed research could materially change the estimated effect.

How headphones compare with proven prevention
For patients at risk of PONV, clinician-directed prophylaxis has a much stronger evidence base than headphones. A Cochrane network meta-analysis covering 585 trials and 97,516 participants found convincing preventive evidence for several antiemetic drugs, including aprepitant, ramosetron, granisetron, dexamethasone and ondansetron.
| Option | Evidence for preventing PONV | What the evidence covers |
|---|---|---|
| Noise-cancelling headphones | Not established | A registered 192-person trial is planned; no completed efficacy result is available |
| Auditory stimuli during general anesthesia | Heterogeneous | Sixteen studies were reviewed, but results could not be pooled in a meta-analysis |
| Nonpharmacological interventions overall | Mostly low or very low certainty | A 2026 network meta-analysis included 54 randomized trials and 8,275 participants |
| Selected antiemetic medicines | More convincing preventive evidence | A Cochrane network meta-analysis covered 585 trials and 97,516 participants |
This comparison does not mean headphones have no value. They may help some people feel calmer, sleep, or tolerate the operating environment, but those possible comfort benefits are different from preventing vomiting and have not been established as a PONV treatment.

Should you bring headphones to surgery?
You can ask your care team whether you may bring or use them, but approval depends on the procedure, anesthesia plan and hospital rules.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problems- Ask before the operation. Confirm whether headphones are allowed during preoperative preparation, anesthesia induction or recovery. Staff may need unobstructed access to your ears, face and monitoring equipment.
- Discuss your PONV risk. Tell the anesthetist if you have previously experienced nausea or vomiting after anesthesia, motion sickness, medication sensitivities or other relevant history.
- Agree on a prevention plan. Ask which antiemetic medicines or anesthesia adjustments are appropriate for you. Do not delay or decline prescribed prophylaxis in favor of headphones.
- Follow infection-control instructions. A personal device may need cleaning, a disposable cover or storage outside the operating room. Staff instructions take priority.
- Use them only as an adjunct. If permitted, headphones can be treated as a comfort measure while the clinical team manages nausea risk and monitors recovery.
What to do if nausea or vomiting occurs
Tell recovery-room staff promptly rather than trying to manage symptoms alone. They can assess possible causes, provide rescue antiemetic treatment, manage pain or dehydration, and check for complications. Persistent vomiting, inability to keep fluids down, severe abdominal pain, breathing difficulty, confusion or signs of bleeding require urgent medical attention according to the discharge instructions for your operation.
Bottom line for patients
Noise-cancelling headphones are investigational for preventing vomiting after surgery. A planned randomized trial may provide better evidence, but its preliminary planning percentages are not proof and no completed result currently demonstrates benefit. Bring headphones only if your care team permits them, and regard them as optional comfort equipment—not a replacement for evidence-based antiemetic prevention.
