Soundcore says the Space Q45 uses a three-stage noise-cancelling system that targets low-, mid-, and high-frequency sounds and automatically adjusts ANC according to the surrounding environment.
How the Soundcore Space Q45 handles ANC
The Space Q45 is built around adaptive ANC. Instead of simply applying one fixed level of cancellation, it can adjust the noise reduction based on the environment. Soundcore also provides five levels of noise cancellation through its app, giving you more control when you want to change the strength manually.
Independent testing backs up the Q45’s strong ANC performance. RTINGS found that it provides excellent noise isolation across a broad frequency range, including low-frequency vehicle rumble and office sounds.
SoundGuys also found the Q45 useful for public transportation, where it reduced train and bus noise effectively. Their testing noted that getting a good seal around your ears matters because gaps between the ear cushions and your head can reduce the benefit of ANC.
Tom’s Guide found that the Q45 was particularly effective against low- and mid-frequency sounds. It handled airplane and other steady background noise well, although some higher-pitched sounds could still be heard.
Where the Q45 works especially well
The Q45 makes the most sense when the noise around you is steady and continuous.
For example, imagine wearing the headphones on a long flight. The constant engine rumble is exactly the kind of low-frequency sound ANC is designed to reduce. The Q45 can make that background noise much less distracting while you listen to music, podcasts, or a movie.
The same applies to buses, trains, and busy roads. RTINGS’ testing found the Q45 effective across the frequency spectrum, while SoundGuys reported solid real-world results during public transportation use.
How the Edifier WH950NB handles ANC
The WH950NB uses hybrid active noise cancellation with multiple microphones to monitor surrounding sound. Edifier’s current WH950NB version uses four microphones and a noise-cancellation algorithm designed to reduce ambient and wind noise.
The older WH950NB model was also designed around active noise cancellation and ambient sound modes. Edifier lists ANC as one of its main features, along with LDAC and app-based sound customization.
Independent testing shows that the WH950NB is not far behind the Q45. One direct comparison found the Edifier allowed somewhat more outside sound through than the Q45, while still performing well overall. Human speech and higher-frequency sounds were more difficult for the WH950NB to suppress.
Another comparison found the two headphones’ ANC performance to be difficult to separate in some situations, which shows why the difference should not be treated as huge.
Where the WH950NB works well
The WH950NB can be a good match for steady background noise such as an air conditioner, refrigerator, train, or general office noise.
Its passive isolation also matters. The ear cushions physically block some sound before the electronic ANC even begins working. A proper fit can therefore make a noticeable difference with either headphone.
Which is better for airplane noise?
For airplane travel, the Space Q45 has the stronger case for ANC. Airplane cabins produce a lot of continuous low-frequency engine noise, which is one of the areas where the Q45 performs particularly well. Soundcore specifically positions the Q45 for flights and says its adaptive system can automatically adjust to the noise environment.
The WH950NB is still capable of reducing airplane noise, so choosing it does not mean giving up effective ANC. The difference is that independent comparisons generally place the Q45 slightly ahead when the focus is specifically on overall noise reduction.
Which is better for voices and office noise?
This comparison is closer.
Neither headphone can completely remove nearby human speech. ANC is generally more effective against consistent sounds than unpredictable sounds such as conversations.
The Q45 does a good job reducing office distractions, and RTINGS found it effective against sounds such as keyboard clatter.
The WH950NB can also reduce office noise, but some speech and higher-frequency sounds may remain more noticeable.
If your main problem is a noisy office, the Q45’s strong combination of ANC and passive isolation gives it an advantage, but neither model should be expected to create complete silence.
ANC is not the only difference
If you are choosing between these headphones, looking only at the maximum noise-reduction claim can be misleading.
Soundcore advertises the Q45 as reducing noise by up to 98%, but that figure is a manufacturer claim rather than a guarantee that 98% of every sound will disappear. Soundcore itself explains that the Q45 reduces a wide range of low- and mid-frequency noises but cannot eliminate all surrounding sound or completely remove human voices.
The WH950NB also has strong ANC, but its current version offers some notable differences outside noise cancellation.
Edifier’s current WH950NB version supports LDAC, multipoint Bluetooth, customizable EQ, and up to 45 hours of battery life with ANC enabled.
The Q45 offers LDAC, multipoint connectivity, app-based EQ, and up to 50 hours of playback with ANC enabled.
So if you care about long trips, the Q45’s extra ANC battery life can be useful.
Soundcore Q45 vs Edifier WH950NB for different situations
| Situation | Better fit for ANC | Why |
|---|---|---|
| Airplane | Soundcore Q45 | Strong low-frequency noise reduction |
| Train | Soundcore Q45 | Very good handling of continuous transit noise |
| Bus commute | Soundcore Q45 | Strong isolation and adaptive ANC |
| Open office | Soundcore Q45 | Good reduction of general background noise |
| Nearby conversations | Close | Neither completely removes speech |
| High-pitched sounds | Close | Both can let some high-frequency sounds through |
| Long travel | Soundcore Q45 | Up to 50 hours with ANC |
| Quiet room | Close | ANC matters less when little background noise exists |
The Q45’s advantage is supported by independent testing, but it is not a dramatic difference in every environment. The WH950NB remains a capable ANC headphone, and some direct testing has found the two surprisingly close.
Fit can change the ANC result
Even a strong ANC system can perform poorly if the ear cups do not seal properly.
If your glasses, hair, or head shape create gaps around the cushions, outside noise can leak in. RTINGS specifically notes that fit can affect the Q45’s frequency response, while SoundGuys points out that getting a good seal is important for real-world noise reduction.
This matters when comparing the Q45 and WH950NB because the headphone that seals better around your ears may give you a better personal result than the one with stronger laboratory performance.
Which one should you choose for ANC?
If ANC is the main reason you are buying the headphones, the Soundcore Space Q45 is the stronger choice based on the available independent testing. It handles low-frequency transportation noise very well, offers adaptive ANC, and gives you five levels of manual noise cancellation through the app.
The Edifier WH950NB is still a serious alternative. Its ANC is effective, and some direct comparisons have found the difference between the two to be fairly small.
For a frequent flyer or commuter, the Q45’s combination of strong ANC and 50-hour ANC battery life is especially useful. For someone who also values Edifier’s sound profile and other features, the WH950NB can still make sense.
