Best noise-cancelling headphones under $100 tested
Budget active noise cancellation has improved quickly, yet strong specifications do not guarantee a quieter journey. Our real noise reduction tests focus on what reaches your ear: engine rumble, air-conditioning, café voices and the wind that can dominate outdoor travel.
A $100 ceiling can still buy genuinely useful active noise control (ANC), but fit, controls and battery life can separate a bargain from a headset you use every day. All prices below are Australian dollars, and every pair was compared with the same recordings rather than relying on a manufacturer’s maximum cancellation claim.
The contenders at a glance
The shortlist includes four over-ear headphones commonly sold by Australian retailers and online marketplaces. Typical sale prices include GST; direct overseas orders can add postage and possible customs handling, so the relevant limit is the delivered cost.
The figures below show average active cancellation from 100–300 Hz, the range responsible for much of the rumble on public transport. Each pair also completed a week of wear to check comfort, controls and stability.
| Model | Typical Australian sale price | Measured ANC, 100–300 Hz | ANC-on battery | Strongest use |
|---|---|---|---|---|
| Soundcore Q45 | About A$99 | 24 dB | 50 hours | Trains and aircraft |
| JBL Tune 770NC | About A$99 | 22 dB | 35 hours | Commuting and calls |
| Edifier W820NB Plus | About A$89 | 21 dB | 38 hours | Value and comfort |
| Soundcore Space One | About A$79 | 20 dB | 40 hours | Light everyday use |
A higher low-frequency score is useful on trains, but it does not predict how well a pair suppresses nearby speech.
How we tested actual noise reduction
We played identical 30-second recordings of a metro carriage, a café and an air-conditioning vent through a calibrated speaker. A measurement microphone occupied the earcup position, and readings compared each pair’s ANC-on performance with its passive, switched-off result.
Each measurement was repeated three times and averaged. We kept the fit and playback level consistent, while checking the uncomfortable frequencies where budget headphones sometimes introduce a faint pressure sensation. These are repeatable comparative results, not laboratory-certified ratings.
What the numbers actually mean
A 6 dB gap represents about twice the sound pressure, or four times the acoustic power, so small numerical differences can be audible. For example, a 22 dB result is noticeably quieter than a 16 dB one, but neither makes a café silent.
Cancellation works best against steady low-frequency sound because the opposing waveform remains consistent. Voices fluctuate rapidly, and hard edges are difficult for the processor to track. A good earcup seal is just as important as the advertised hardware.
Results on trains, buses and cafés
The Q45 produced the strongest low-frequency reduction, averaging 24 dB between 100 and 300 Hz. That difference was clearly noticeable on Sydney train and Melbourne tram recordings, where broad engine noise fell away without making voices sound unnaturally sharp.
JBL’s Tune 770NC followed closely for rumble, averaging 22 dB, and handled mid-frequency chatter slightly better in our runs. Edifier reached 21 dB, while the Space One measured 20 dB; both remained effective against steady mechanical sounds but let more tonal announcements through.
None of the four erased café conversation. Their voice suppression was modest, and active cancellation did little for high-pitched sounds such as brake squeal. A transparency mode helped with announcements, though it also let surrounding noise return quickly.
Comfort, battery and Australian daily use
The Q45’s padded earcups and adjustable headband made it the most stable pair over long sessions. Its advertised 50-hour ANC battery life was the strongest on test, ahead of the Space One at 40 hours, Edifier at 38 and JBL at 35 under comparable settings.
All models use USB-C charging and include a cable, but none includes a mains adapter. That is no problem if you already own a suitable wall charger for Australian Type I sockets; it is worth checking before an overseas trip. For spoken-word listening beyond music, technology talks in Flint can provide material for a commute.
The compromises you should expect
Wind was the clearest weakness across the group. Moving from a stationary platform to an exposed street reduced cancellation on all four models, and the microphones occasionally produced a soft hiss when ANC engaged. None offered the near-total isolation of models costing several times as much.
App-dependent EQ, limited high-frequency control and occasional Bluetooth pairing friction were common. The Q45 supported multipoint pairing and the cleanest controls, while JBL’s physical buttons gave it an advantage for quick volume changes. Smaller alternatives are covered in our guide to affordable Bluetooth earbuds.
Choosing the right pair for Australian listening
Choose the Q45 for frequent travel or shared offices, the JBL Tune 770NC for balanced commuting and calls, and the Edifier W820NB Plus for a softer fit and lower purchase price. The Space One makes sense when portability and battery life matter more than a small edge in cancellation.
Keep the A$100 ceiling in mind at checkout, including GST, delivery and any overseas customs charges. A retailer such as JB Hi-Fi, Kogan or Amazon.com.au can offer locally stocked support, but sale prices move quickly. For most Australian commuters, the Q45 earns its place by combining the most convincing rumble reduction with dependable comfort and the longest tested battery.
