Sony WH-1000XM5
~$279–$349
Bose QuietComfort 45
~$199–$279
These are the two headphones most people end up choosing between. The Sony WH-1000XM5 has stronger ANC, LDAC hi-res wireless, and better call quality. The Bose QC45 is lighter, folds smaller, works wired when the battery dies, and often runs $50–$70 cheaper. Here is exactly what each one does better.
Best overall
Sony WH-1000XM5
Better ANC, LDAC support, longer battery, and cleaner call quality. The best noise-canceling headphones under $350 for most people.
Bose QuietComfort 45
Lighter build, passive wired audio when the battery dies, simpler controls, and a smaller travel case. The right choice if you wear headphones 8+ hours a day.

Noise Cancellation
The XM5’s ANC is the defining advantage. Sony uses 8 microphones and a dedicated V1 chip — hardware designed from scratch for noise cancellation rather than adapted from a general audio processor. In real-world testing on planes, commuter trains, and open offices, the XM5 cancels significantly more low-frequency engine drone and ambient noise floor than the QC45.
The QC45’s ANC is still excellent and lands in the top tier of noise-canceling headphones overall. If you are comparing either of these to older ANC headphones or budget pairs, both will feel like a major upgrade. The gap only becomes clear when you A/B test them back to back in a genuinely loud environment.
Sony WH-1000XM5 — noticeably cleaner low-frequency cancellation, especially on flights and loud commutes.
Sound Quality
Sony tunes the XM5 with a slight V-shape: lifted bass and boosted treble with a mild mid-range dip. The result is energetic and fun on pop, hip-hop, and electronic music. Bose goes warmer and flatter on the QC45, with a fuller mid-range that serves podcasts, vocals, and acoustic music well. Both are enjoyable; the difference is tuning philosophy, not quality.
Where Sony pulls clearly ahead: LDAC. If you stream lossless audio through a compatible Android device, LDAC delivers near-CD quality wirelessly — roughly three times the data rate of AAC. The QC45 caps out at AAC, which handles Spotify and Apple Music streaming perfectly fine but cannot match LDAC for critical listening or lossless sources.
Sony XM5 for LDAC and hi-res streaming. Bose QC45 for warm, vocal-forward tuning.
Comfort & Build
Both are comfortable for multi-hour sessions. The QC45 is marginally lighter at 238g vs. 250g, and its ear cups use softer padding that many people prefer for 8+-hour workdays. The XM5 has a redesigned unibody headband with no visible notch slots — sleek-looking but less adjustable-feeling than traditional sliders.
Portability goes to Bose: the QC45 folds into a rounder, more compact case that fits easily in a backpack front pocket. The XM5 folds flat but ships in a larger oval case. Build quality is close, though many reviewers find the Bose hardware feels slightly sturdier at the hinges.
Bose QC45 — lighter, softer padding for long sessions, more compact case for travel.
Call Quality
Sony’s Precise Voice Pickup Technology leverages all 8 microphones to isolate your voice and suppress wind, keyboard noise, and background chatter. Call recipients consistently rate XM5 calls as cleaner than QC45 calls, especially in noisier environments. The QC45 handles calls fine for everyday use but cannot match the XM5 in demanding conditions.
Sony WH-1000XM5 — cleaner voice isolation in loud environments.
Battery & Wired Use
The XM5 wins on raw hours: 30 vs. 24 with ANC on, both on USB-C. Quick charge is faster on Sony too — 3 minutes gives you 3 hours vs. Bose’s 15 minutes for 2.5 hours. For most use cases the extra 6 hours is a clear win.
There is one real-world catch with Sony: the XM5 requires a charged battery to pass audio through the 3.5mm cable. If the battery dies mid-flight, plugging in a wired connection produces silence. The QC45 plays audio passively through the cable even with a completely dead battery. For frequent travelers who use wired audio as a backup, this is a meaningful practical difference.
Sony XM5 on battery life. Bose QC45 on wired reliability — works as passive headphones when dead.
VERDICT — WHICH ONE SHOULD YOU BUY
Buy the Sony XM5 if…
You want best-in-class ANC, LDAC hi-res wireless, 30-hour battery, and the cleanest call quality under $350. The top pick for most people.
Buy the Bose QC45 if…
You wear headphones 8+ hours a day and prioritize lighter weight and softer padding, or you need wired audio as a fallback when the battery dies.
For most commuters, remote workers, and frequent flyers — the Sony XM5 is the pick. The Bose earns its place if comfort for 8+ hours matters most, or you need passive wired audio as a backup.
