By aspect — in detail
The axis that matters most, and the split is not about taste — it is about how long you have had the headphone. Reviewers unbox a metal-reinforced headband, aluminium hinges and a chassis that feels a class above the price, and say so emphatically. Owners a year in describe the plastic yoke where the metal slider enters the earcup cracking, frequently on both sides, sometimes far enough for the band to pop out. The failure is specific and repeatable enough that third parties sell replacement headbands and publish 3D-printable parts for it.
Measured
The nearest thing to hard data on longevity is the shape of the owner ratings rather than a lab test: Amazon's US listing averages 4.3 from 14,150 ratings, but the histogram runs 66% five-star against a 10% one-and-two-star tail — heavier than a headphone this well-reviewed would normally carry. The repair ecosystem corroborates it; an iFixit answer posted in January 2026 opens “If you have Soundcore Space Q45 that has broken headband plastic, like thousands of others, this is a solution” and links a printable replacement base. Weight is the other build fact, and the published figures disagree: SoundGuys lists 281 g, Tom's Guide 10.3 ounces, and RecordingNOW put its own pair on a scale at 297.5 g — heavy for the class either way, which is the price of the metal.
⚠ vs. listeners — Nobody is wrong here. A one-week review unit genuinely does feel better made than its rivals, and the same headphone genuinely does crack at a known point months later, so the reviews and the owner reports describe different phases of the same object rather than different opinions of it.
Where it splits
Best-in-class construction for the money — metal where it counts, no creak, and it feels like a $200–$300 headphone.73%
“Comfortable and well-built design.”
RTINGS
It cracks. The plastic around the headband slider gives out after months of ordinary use, and support treats it as wear rather than a defect.27%
“The plastic on the part where the metal band slides into the earpiece on both sides has cracked in the same exact spot.”

Isolation
Contested · 8 srcThe reason most people buy it, and the majority verdict is that it punches well above $150 — strongest on the low-frequency rumble of planes, buses and traffic, with five manual levels plus an adaptive mode. Two dissents are worth knowing: a reviewer who has since heard the newer competition finds it lets specific frequencies straight through even at maximum, and several sources note a faint masking hiss that grows as you raise the ANC level. Passive isolation is good on its own.
Measured
TechGearLab measured active attenuation of 19.1 dB in the lows, 23.1 dB in the mids and 41.6 dB in the highs, against group averages of 15.6, 22.4 and 36.9 dB — above average in every band, and furthest above it down low. SoundGuys places the same result relative to the class leaders: “The ANC is fairly solid, although it doesn’t compare as well to market-leading headsets like the Sony WH-1000XM5”.
⚠ vs. listeners — The hiss is the recurring qualifier and it is consistent across independent sources: PCMag hears “a thin band of higher-frequency masking hiss”, and Head-Fi's reviewer reports that “increasing the ANC to higher levels will increase the hiss at higher frequencies”. So the measured attenuation and the complaint are compatible — it blocks a lot, and it adds a little of its own noise doing it.
Where it splits
Excellent for the price and genuinely effective on engine and traffic rumble — the closest a budget set gets to the flagships.81%
“It can easily cut down annoying noise like the hum of a bus or plane engine, as well as ambient voices, so that you can focus on your trip.”
RTINGS
Tuned narrowly — it flattens the noises it was aimed at and leaves the rest audible, and some units get worse over time.19%
“the Q45 just freely lets in certain frequencies with ease, even when set to the max level”
RecordingNOW (ODi Productions)
Tonality
Contested · 7 srcThe measured signature is not in dispute: warm, with the bass mildly lifted and an uneven top end. What it is worth is very much in dispute. One group of listeners hears a full, consumer-friendly voicing that suits most music and can be reshaped in the app; the group that measured it against a preference curve hears deviations in every region and calls the sound the weakest part of an otherwise strong product.
Measured
RTINGS reads Sound Signature “Warm,” Bass Amount “Emphasized (3 dB)” and Treble Amount “Balanced (0 dB)” — a gentle consumer tilt, not a bass cannon. TechGearLab, measuring against its own target, is blunter about the result: “The Soundcores take some misteps in the frequencies, creating a mix that is less appealing than many competitors, but one of the better budget mixes.” Head-Fi's reviewer, reading published measurements, calls the shape W-shaped with “several dramatic peaks”.
⚠ vs. listeners — A 3 dB bass lift and a balanced treble average sound mild on paper, which is why the listening reports run hotter than the headline numbers: the character comes from the unevenness within the bands, not from the level of any one band. It is also mode-dependent — PCMag notes that “Each mode in the Ambient Sound section delivers a different sound signature with varying degrees of bass depth and brightness.” So ANC on and ANC off are not the same headphone.
Where it splits
Rich and full — a sculpted, likeable consumer tuning that most listeners will enjoy without touching the EQ.48%
“Full-bodied audio experience with rich lows and bright highs”
PCMag (Tim Gideon)
Measurably off in every region — adequate if you are not listening closely, and clearly the weak link if you are.52%
“The frequency response curve deviates noticeably from our headphone preference curve across all areas of the frequency spectrum.”
SoundGuys (Riley Ballantyne)
The most polarised sonic aspect, and the argument is about evenness rather than quantity. One camp hears bright, crisp, detailed highs with only mild sibilance. The other hears a top end that is erratic enough to make cymbals sound wrong and speech sound hissy — TechGearLab reports actually turning the volume down on podcasts because of it. The measurements support both: the band sits at roughly the right level and is visibly ragged inside that level.
Measured
RTINGS reads Treble Amount “Balanced (0 dB)”. TechGearLab's expert-ear treble score is 3.4 out of 10 against a 6.3 group average — its lowest sub-score by a wide margin — and its listening note is “The treble is pitchy and inconsistent, making it the weakest link for us.” SoundGuys measured the mechanism: “the higher frequencies are besieged by an undulating change in response that causes high-end elements in music to sound hissy”.
⚠ vs. listeners — A treble that measures balanced on average and reads as harsh to listeners is not a contradiction — averaging a run of peaks and dips returns roughly zero. That is why the complaint is so specific (cymbals, sibilants, speech) rather than a general “too bright,” and why the app's EQ helps some people more than others depending on which peak is bothering them.
Where it splits
Bright and detailed — crisp highs that bring out air and clarity, with only a touch of extra sibilance.56%
“The higher-register brass, strings, and vocals exhibit plenty of detail and clarity”
PCMag (Tim Gideon)
Uneven and fatiguing — the single worst thing about the headphone, and especially rough on spoken word.44%
“By far, the biggest issue with the sound on the Anker Soundcore Space Q45 is its very uneven high-end response.”
SoundGuys (Riley Ballantyne)
Sources split cleanly on the midrange, and the split tracks how closely they were listening. Reviewers describing music at normal attention hear rich, well-bodied vocals; reviewers comparing against references hear a scooped lower midrange and a timbre that does not sound like the real instrument. There is one measured fact both can point to: a dip in the low mids.
Measured
SoundGuys measured the dip and named its range — “the mid scoop around 200 Hz to 500 Hz noticeably impacts some songs” — and reports the midrange “depressed slightly” against its preference curve. TechGearLab scores the mid-range 6.1 out of 10 against a 7.2 group average. Head-Fi's reviewer, hearing the same region positively, puts it as “mostly focused at the centre with a slight slant to the upper mids”.
Where it splits
Full and present — vocals get real body and sit properly in the mix.48%
“Callahan’s baritone vocals receive plenty of low-mid richness and matching high-mid crispness.”
PCMag (Tim Gideon)
Recessed and synthetic — voices and lead instruments lose body and stop sounding like themselves.52%
“Vocals and lead instruments tend to sound artificial, as if they are asking a machine to reproduce the sound of a guitar or a famous singer, and it spits out something close to the real thing, but not the real thing.”
TechGearLab (Rachael Lamore)
Soundstage
Contested · 3 srcA genuinely bimodal aspect with no measurement to settle it. Two sources describe an unusually wide, immersive presentation for a closed-back; the source that scored it formally rates it below its group average and describes a small, badly proportioned space. Both sides agree instruments can be placed; they disagree about how much room there is between them.
Measured
TechGearLab is the only source that scores soundstage on a scale: 5.4 out of 10 against a 6.7 group average and a 9.6 best-in-test. It also allows what the other camp is hearing — “There is adequate width but not much height” — which is roughly where the two descriptions meet.
Where it splits
Wide and immersive — one of the more spacious presentations you will find at this price.62%
“Anker’s soundstage is wide and immersive”
Tom's Guide (Alex Bracetti)
Boxed in — the sound happens inside a small, unflattering room rather than around you.38%
“The Q45 soundstage has a weird, boxed-in quality to the overall soundscape. Not only does it feel like a small room, but it's a small room with poor acoustics.”
TechGearLab (Rachael Lamore)
Everyone agrees there is more bass than neutral and that it never distorts, even loud. The disagreement is about control: some hear a warm, well-behaved low end that stays in its lane, others hear it turn loose and messy, and one long-term owner calls it outright boomy. The optional BassUp mode is a separate question — it adds weight and costs clarity, and its behaviour changed with firmware.
“The bass reaches fairly low but is a tad lacking in terms of thump, but overall well-controlled and not bloated.”
Head-Fi (FYLegend)
“At times, the bass feels a bit uncontrolled and veers towards messy, but it does add a layer of warmth.”
TechGearLab (Rachael Lamore)
Measured
RTINGS reads Bass Amount “Emphasized (3 dB)” — real but modest. SoundGuys measured the lift lower down, “The sub-bass is slightly exaggerated,” yet found it did not pay off in practice: “The slight bump in the sub-bass doesn’t really transfer over to a perceptible benefit in bass-heavy genres such as house music.” TechGearLab scores bass 6.2 out of 10 against a 6.9 average, its strongest sonic sub-score. PCMag, listening rather than measuring, reaches the opposite headline — its stated con is “Light on sub-bass frequencies” — which is the usual gap between a measured shelf and how much of it you feel.
Broadly positive with one consistent asterisk. The memory-foam pads and padded headband make multi-hour sessions genuinely workable, and two sources rate it more comfortable than headphones costing several times more. The asterisk is heat: the pleather does not breathe, and it warms up quickly. Glasses wearers and anyone with deep ears should note the cups are roomy in diameter but shallow.
“Faux leather lines the underside of the headband and earpads, for a secure and comfortable fit even over long listening sessions.”
PCMag (Tim Gideon)
“The arcups are round and feel roomy, even with larger ears, but they are sort of shallow, and some of us could feel the outer pinna of our ears rubbing against the inside of the cups. The materials are skin-friendly, but they get hot fairly quickly.”
TechGearLab (Rachael Lamore)
Measured
TechGearLab scores comfort 6.4 out of 10 but still managed “about 6 hours, even with glasses”; SoundGuys scores it 8.2 and RecordingNOW 9.0. The one dissent is postural rather than material — Head-Fi's reviewer reports that “The headband under certain conditions does exert some pressure”, giving a fatiguing hot spot on the forehead. Weight is the other variable: measured figures run from 281 g to 297.5 g, heavy for the class.
Mixed, and it lines up with the treble split rather than existing independently. Sources that get on with the top end report good resolution and separation for the money; the source that does not describes the whole presentation as subtly off, as though the recording itself were a poor copy. Nobody claims class-leading resolution in either direction.
“the soundstage is quite wide with excellent detail retrieval and instrument separation”
Head-Fi (FYLegend)
“It feels like listening to a knock-off version of a song we know and love, but the production is poor instead of the immaculate recording we're used to.”
TechGearLab (Rachael Lamore)
The quietest aspect in the set and the one with the least spread. Sources agree you can place instruments and follow individual lines, and agree that layering — how cleanly sounds stack behind one another — is where it gives ground to better headphones. One listener adds that the whole presentation sits a few rows back rather than up front.
“There is a decent sense of location; we can discern where each voice is originating from, and there is a general sense of distance between each instrument. Harmonies don't get lost, though sometimes they gently mush together, but the layering feels weaker than some competition.”
TechGearLab (Rachael Lamore)
“In terms of imaging, the presentation is a tad distant, as if I am in the middle row of a concert rather than the front row.”
Head-Fi (FYLegend)
The dominant verdict is that it is a lot of headphone for the money — the battery, the case, LDAC and the ANC together are hard to match near $150, and harder still when it drops nearer $90. The dissent is narrow but firm: the outlet that ranked it against 26 rivals put it 16th and pointed at cheaper sets that sound better, and a long-term owner notes that Soundcore's own newer models now undercut it on sound.
Measured
The price the verdict is written against has moved. Soundcore's own US store still lists $149.99 with no discount, while live retail widgets on the sourced pages show $119 at Amazon (PCMag) and $139.99 with a $89.99 refurbished option (RecordingNOW). RecordingNOW makes the dependency explicit: “At full price, I’m less excited about the Q45. But I’ve seen them on sale for around that $90 price point, which I think is a fairly amazing value.”
Where it splits
A bargain — flagship features and near-flagship noise cancelling for a third to a half of flagship money.80%
“the $150 USD price tag only sweetens the deal”
SoundGuys (Riley Ballantyne)
Not the best use of $150 — you are paying for noise cancelling and giving up sound quality that cheaper rivals deliver.20%
“Overall, we aren't big fans of the Q45, and there are better choices in this price range.”
