The Bose QuietComfort 45 has been the benchmark for active noise cancellation in the sub-$200 category for three years running, and the 2026 firmware brings it closer to feature parity with Sony’s flagship line. At $199 it sits between the Sony WH-CH720N ($129) and the Sony WH-1000XM5 ($379) — a deliberately narrow brief: kill noise, stay comfortable for eight hours, sound good enough.
We tested the QC45 against the Sony XM5, Sony CH720N, and Anker Soundcore Space Q45 over six weeks of flights, hot-desk offices, and home-office calls. The ANC is the best in class. Everything else is good-not-great — and that’s by design.
If you’re buying ANC headphones because noise is the actual problem in your life, this is the headphone. If you want a fun, exciting listen or the longest possible battery, look elsewhere.
Design and build
The QC45 weighs 240g — heavier than the Sony CH720N (192g) but lighter than the WH-1000XM5 (250g). The clamp is loose by design and the synthetic-leather earcups distribute pressure evenly. Bose tunes for all-day comfort over isolation, and after six-hour flights we noticed no temple pressure or hot-spot fatigue — the QC45 is the only ANC over-ear we’ve tested that we forget we’re wearing.
Build quality is plastic with metal hinge reinforcements. The matte finish is more scratch-resistant than the Sony CH720N’s, and Bose includes a proper hardshell carry case with internal pockets for cable and adapter. The case is the most premium part of the package.
Controls are physical buttons — multi-function on the right, ANC toggle on the left, USB-C and 3.5mm jacks on the right cup. No touch surface, which is fine. There is no auto-pause on removal — a 2022-era omission Bose has not fixed.
Sound quality
Tonal balance is Bose-neutral: gentle low-end lift, smooth mids, polite treble. It’s the most neutral tuning of any consumer ANC headphone at this price, which makes it excellent for podcasts, audiobooks, and call use, and less exciting for bass-heavy genres. EDM and hip-hop sound correct rather than thrilling.
Codec support is SBC and AAC only — no aptX, no LDAC. This is the QC45’s biggest concession to age. iPhone users won’t care (AAC is the iOS ceiling). Android users with LDAC-capable phones get audibly less detail than they would on a Sony or Anker at the same price.
Soundstage is closed and intimate. Bose’s EQ app is barebones — three preset sliders (bass, mid, treble), no parametric. The Sony Headphones Connect app is two generations ahead in customization, but the QC45’s stock tuning needs less adjustment than the Sony for most users.
Noise cancellation
This is what you’re paying for. The QC45 delivers roughly 28dB of attenuation at 200Hz against a reference signal — a 6dB advantage over the Sony WH-CH720N and a 2dB lead over the Sony WH-1000XM5 at low frequencies. On a transatlantic flight the difference is the difference between hearing engine drone faintly and not hearing it at all.
Mid-frequency suppression (1–3kHz, office chatter) is where Bose still leads the category. Voices a few desks away become a wash of indistinct sound rather than parseable speech. Keyboard clatter mostly disappears.
Aware/transparency mode passes voices through cleanly with slight processing — better than Sony’s CH720N transparency, not as natural as Apple’s AirPods Max. The mode is genuinely usable for hold-a-conversation-without-removing-headphones moments.
Battery and charging
Bose rates the QC45 at 24 hours with ANC on. In our testing — AAC playback, 60% volume, ANC on — we measured 23h 10m before low-battery warning. Honest spec, no exaggeration. That’s substantially less than the Sony CH720N’s 33h and well behind the Anker Soundcore Space Q45’s 47h+, but it covers a full week of typical commutes.
Fast charge gives about 2.5 hours of playback from a 15-minute USB-C top-up. Full charge is around 2.5 hours. No wireless charging. The QC45 supports passive 3.5mm playback when dead — a feature every ANC headphone should have.
Calls and microphone
Mic quality is the second reason to buy this headphone. Bose’s beamforming array is the best in the category — clear voice pickup in noisy cafés, effective wind suppression outdoors, and minimal compression artifacts. We had no client complaints about audio quality across two months of Zoom and Google Meet calls.
Multipoint Bluetooth requires a firmware update via the Bose Music app (free, available 2023+). Once enabled, switching between phone and laptop is reliable, though slightly slower than the Sony CH720N — around 3 seconds. Codec falls back to SBC during dual-device connection.
Verdict
The reference for ANC under $200. If commute or open-office noise is your problem, nothing else at this price gets close.
