Why you should trust this review
I have reviewed audio gear for 14 years across Engadget and What Hi-Fi. For this review I purchased the Anker Soundcore Space Q45 at $99 in December 2025. Anker did not provide a sample. Across 4 months I have logged roughly 95 hours of use across daily commutes, two domestic flights, and our acoustic lab.
I tested the Space Q45 directly against the Sony WH-1000XM5, the Sennheiser Accentum Plus, and the older Anker Soundcore Q30 on identical source files (Apple Music Lossless on iPhone 16 Pro and Tidal Master on a Pixel 9 Pro for LDAC). Every measurement was verified on our test bench.
How we tested the Anker Soundcore Space Q45
Our headphone protocol runs a minimum of 30 days. For the Space Q45 we extended that to 122 days. Specifically:
- ANC attenuation, calibrated dB meter in our 8-by-8 acoustic lab at six frequencies (50 Hz, 100 Hz, 500 Hz, 1 kHz, 5 kHz, 10 kHz).
- Battery life, pink noise at 50 percent volume on AAC, both ANC on and ANC off, until shutdown. Repeated 3 times per condition.
- Comfort, clamping pressure (in N per square cm), weight distribution, and a 4-hour wear test with 30-minute check-ins.
- Call quality, outgoing voice graded across 5 environments against a Shure SM7B control track.
- Codec test, parallel A/B between AAC and LDAC on the same Pixel source.

Who should buy the Anker Soundcore Space Q45?
Buy these if you:
- Have a hard $100 ceiling and want a real flagship-style over-ear experience.
- Want the longest battery in the budget class. 49 hours is genuinely class-leading at any price.
- Use Android and want LDAC, rare in this price band.
- Travel often and want a folding case-friendly design.
Skip these if you:
- Want flagship-level ANC. The Sony WH-1000XM5 measures 12 dB stronger.
- Need crystal-clear call quality. The microphone array is mediocre in noisy environments.
- Want a premium-feeling build. The plastic does not match Sony, Bose, or Sennheiser.
- Train at the gym. These have no IP rating, the synthetic earpads get clammy fast.
Battery life: a budget headline that is genuinely true
Anker rates 50 hours of playback with ANC on. In our standardized test (50 percent volume, AAC, ANC on, pink noise) we measured 49 hours and 36 minutes across three runs, within 1 percent of the claim. With ANC off, we measured 64:48 against a 65-hour rating.
That puts the Space Q45 alongside the Sennheiser Accentum Plus at the top of the over-ear battery category. Real daily use, at roughly 90 minutes per day, has me charging every 28 to 32 days. That is functionally a “charge it monthly” headphone.
Noise cancellation: good for the price, not flagship
In our calibrated lab tests, the Space Q45 averaged 24 dB of attenuation across our six test frequencies. That is 12 dB behind the Sony WH-1000XM5’s 36 dB and 4 dB behind the Sennheiser Accentum Plus’s 28 dB.
In practice, the ANC handles office and commute environments well, takes some edge off subway and bus noise, and noticeably falls behind on planes. On a 4-hour LAX to ORD leg, the Space Q45 reduced cabin drone enough to be tolerable but I had to push volume to roughly 70 percent. The Sony WH-1000XM5 on the return leg sat at 55 percent for the same perceived loudness.
Sound quality: warm and tunable
Out of the box, the Space Q45 tune warm with a 4 dB bass lift around 80 Hz. The Soundcore app gives you a 9-band parametric EQ and 22 presets, the deepest EQ controls of any headphone we have tested under $200. After 4 months my daily preset is bass minus 2, low-mid plus 1, treble plus 1, which gives a much flatter response than default.
In blind A/B against the Sennheiser Accentum Plus on 15 reference tracks, our panel split: 6 of 10 preferred the Sennheiser for warmth and image stability, 4 of 10 preferred the Anker after EQ tuning for clarity and bass control. Without EQ, the Sennheiser wins more often.
LDAC is real on Android. We measured a 1 to 2 dB improvement in resolved detail above 8 kHz versus AAC on the same Pixel source. It is the kind of detail you hear at home, not on a noisy commute.
Comfort: good for the weight
At 289 g, the Space Q45 is heavier than the Sony WH-1000XM5 (250 g) and the Sennheiser Accentum Plus (222 g). Clamping pressure measures 2.5 N per square centimeter, comfortable across our 4-hour wear test for 8 of 9 panelists. The synthetic leather earpads get warm in summer but stayed below “uncomfortable” through 4 months of daily use.
After 4 months the earpads show light wear at the seam. They are user-replaceable for $19, which is rare in the budget tier.
Call quality: the budget compromise
In our 5-environment call test, the Space Q45 placed bottom 2 in 4 of 5 environments. The microphone array struggles with noisy cafes, gyms, and windy outdoor calls. In a quiet office, the calls sound fine.
If you take a lot of calls, the Sennheiser Accentum Plus or any flagship is a better buy. If you mostly listen rather than talk, the Space Q45’s compromise is easy to accept.

Should you buy the Anker Soundcore Space Q45?
The Anker Soundcore Space Q45 is the over-ear we recommend when someone has a hard $100 ceiling. We measured 49 hours and 36 minutes of real battery (against a 50-hour rating with ANC on), 24 dB of average ANC, and LDAC support that no other sub-$150 headphone offers. Sound quality is good with the included EQ, app stability is solid, and build is plastic-but-fine. It is not a Sony killer, it is a 60-percent-of-Sony-for-30-percent-of-the-price proposition that holds up after 4 months of testing.
Frequently asked questions
Are the Anker Soundcore Space Q45 worth $99 in 2026?+
Easily. We have not tested another sub-$100 over-ear that gets battery, codec support, and app polish this right. The compromises are ANC depth and microphone clarity, both predictable trade-offs at this price.
Space Q45 vs Sennheiser Accentum Plus: which should I buy?+
Pick the Space Q45 if your ceiling is firm at $100 or you specifically want the longer battery and folding design. Pick the [Accentum Plus](/reviews/sennheiser-accentum-plus) if you can stretch to $179 for better build, slightly stronger ANC (28 dB vs 24 dB), and better call quality.
How honest is the 50-hour battery rating?+
Very. We measured 49 hours and 36 minutes with ANC on at 50 percent volume on AAC across three runs, within 1 percent of the spec. With ANC off, 64:48 against a 65-hour rating. Both numbers are unusually honest for the budget tier.
Is LDAC actually noticeable on a $99 headphone?+
On critical listening with high-res tracks via Android, yes. The 40mm drivers resolve the extra detail in cymbals and reverb tails. On a noisy commute the difference vanishes. Use LDAC at home, AAC on the move.
Are the Space Q45 good for travel?+
Yes. They flat-fold into the included case (smaller than the Sony WH-1000XM5 case), the 50-hour battery covers any flight you can think of, and they have a wired 3.5mm option for in-flight entertainment. ANC on planes is decent, not flagship-level.
