Soundcore Space Q45 review: most of the quiet, little of the money

1. Best budget pick

Soundcore Space Q45

Fifty rated hours with canceling on, a hard case and a 3.5 mm cable in the box, at a fraction of flagship money. The compromise is in the last 10 percent of quiet, not the first 80.

Our editorial score: 8.2 / 10

The interesting thing about the Space Q45 is not that it is cheap. It is that on three of the five criteria this site scores on — battery, wired fallback and case — it matches or beats headphones costing several times more.

Fifty rated hours with canceling on is longer than any flagship here except the Sennheiser. The hard case is included. So is the 3.5 mm cable. What you give up is concentrated almost entirely in one place: the depth and steadiness of the canceling itself.

What works on a plane

• +Up to 50 rated hours with canceling on, which beats every flagship here
• +Hard case and 3.5 mm cable included, so nothing else to buy for a seatback screen
• +Five minutes of charge buys four hours, which covers a gate-side mistake
• +The cheapest way to get genuinely useful drone reduction on a plane

What does not

• −Soundcore's own 98 percent figure is a marketing claim, not a measurement, and the gap to Bose is audible
• −295 g with plainer pad materials, so hour four is less comfortable than the Sennheiser's
• −Plastic build will not survive being crushed in an overhead bin the way the metal Apple would

Buy it if you fly a handful of times a year. The economics are simple: a flagship costs several times as much to remove the last slice of engine drone, and if you are on a plane four times a year you will not accumulate enough hours to justify it. Buy it also if you are buying for someone else and do not know their preferences, or if you are the kind of traveler who loses things.

Do not buy it if you fly constantly, because the fatigue difference compounds and the pads are plainer. Do not buy it if you need the canceling to hold steady while cabin noise changes, because that steadiness is precisely what flagship processing buys. And do not buy it expecting it to survive being crushed in an overhead bin the way the metal AirPods Max would.

Soundcore markets the Space Q45 as reducing noise by up to 98 percent with a three-stage system. That figure is a manufacturer marketing claim rather than an independent measurement, and it should be read as such — a percentage reduction without a stated frequency band or measurement standard is not a comparable number.

What is fair to say is that against steady low-frequency drone it does genuinely useful work, and that the difference between it and a flagship is smaller than the price difference. The first eighty percent of the quiet is cheap now. Where the gap shows up is the deepest part of the band, and in how the system behaves when the noise around you changes — a flagship settles, a budget adaptive system hunts a little.

The gap between this and a flagship is audible. It is not the size of the price difference.

Soundcore rates it at up to 50 hours with canceling on and up to 65 with it off, and quotes five minutes of charge for four hours of playback.

The four-hours-from-five-minutes figure is the genuinely useful one. It covers the specific failure mode where you realize at the gate that you forgot to charge — ten minutes at a terminal outlet and you have enough for a transatlantic leg.

The Space Q45 folds and ships with a hard-shell case. That puts it in exactly the same practical position as the Sony: a compact block that protects the hinge, rather than a wide flat object or an unprotected headband.

For a budget product to include the case is worth noting, because the case is a real cost and a real omission when it is missing. The Apple AirPods Max ships a soft cover that leaves the headband exposed; this ships a hard shell. On this specific criterion the cheap headphone is straightforwardly better equipped.

Approximately 295 g, which is at the heavier end of this field. More importantly, the pad and headband materials are plainer than the flagships’. They are perfectly fine for two or three hours; by hour five you will notice more heat and more pressure than in the Sennheiser.

This is the criterion where the price shows most clearly, and it is also the one that is hardest to judge in a shop. Pad comfort at hour five is a material-science problem, and material science is expensive. If your flights are routinely long, this is the argument for spending more.

A 3.5 mm cable is in the box along with the hard case and the USB-C cable, so the Space Q45 will work with a single-socket seatback system with nothing extra purchased. Older twin-socket aircraft still want a two-prong adapter, as with every headphone here.

Worth saying plainly: on the in-flight-entertainment criterion, this sub-flagship headphone beats the most expensive over-ear on this site outright, because Apple ships no cable at all. See best wired headphones for flights for the full picture of who includes what.

• EarFun Air Pro 4 — the budget earbud equivalent, at 11 rated hours per bud and 52 with the case. If pack size matters more than comfort, go here instead.
• Sony WH-1000XM6 — what the extra money actually buys: 40 g less weight, deeper canceling, better pads, LDAC.
• JBL Tour One M3 — the mid-to-upper option with the Smart Tx transmitter for in-flight entertainment.

Where it sits in our roundups

The Space Q45 leads best budget noise-canceling headphones for flights and best noise-canceling headphones under $200, and appears in best headphones for long-haul flights on the strength of its battery alone.
