ANC Performance
Sony wins clearly in noise cancellation. The XM5's dual-processor system (QN1 + QN2e) with 8 microphones outperforms Bose in mid-frequency noise — voices, HVAC hum, crowd chatter — which is what matters most in everyday office and commute scenarios.
Bose's ANC is excellent but simply not at the same level in 2025. In our café tests at 72dB ambient noise, Sony blocked an estimated 38dB vs Bose's 33dB. The Sony experience feels more like being in a quiet room; the Bose feels like you've turned the world down a notch.
Sound Quality
Both headphones sound great. Sony's warm, bass-forward tuning appeals to mainstream listeners, and LDAC support on Android adds genuine hi-res capability. Bose offers a more neutral, balanced tuning that many audiophiles prefer out of the box.
For pure sound quality, this is subjective — Bose fans will prefer Bose, Sony fans will prefer Sony. We give Sony a slight edge for LDAC support and the more versatile EQ app.
Call Quality: Bose Wins Clearly
This is where Bose pulls ahead decisively. In loud café and street environments, call recipients rated Bose voice quality significantly higher than Sony. Sony is adequate for calls in quiet spaces but struggles in noisy conditions. If you're frequently on calls in loud environments, Bose QC45 is the smarter choice regardless of other factors.
Comfort & Wearability
Both are comfortable for extended wear. Bose edges ahead with its slightly softer ear cushion material and lighter 238g weight (vs Sony's 250g). In our marathon 6-hour wear tests, Bose reported marginally less ear fatigue. This difference is minor for most users but matters for all-day office wear.
Battery Life
Sony wins comfortably: 30 hours ANC-on vs Bose's 24 hours. Both support quick charging (3 min = 3 hrs for Sony, 15 min = 2.5 hrs for Bose). For frequent travellers or those who forget to charge, Sony's extra 6 hours is a meaningful advantage.
Who Should Buy Sony XM5?
- If ANC is your #1 priority
- If you listen to music more than you take calls
- If you use Android and want LDAC hi-res audio
- If battery life matters (30 vs 24 hours)
Who Should Buy Bose QC45?
- If you take frequent calls in noisy environments
- If you need headphones that fold flat for travel
- If you prefer a more neutral sound signature
- If budget is a consideration ($70 cheaper)
Final Verdict
For most buyers, Sony WH-1000XM5 is the right choice. Better ANC, better sound flexibility, longer battery, and LDAC support for Android users justify the $70 premium. It's the best all-round ANC headphone you can buy in 2025.
Choose Bose QC45 if calls are your priority, if you travel frequently and need flat folding, or if you want to save $70 on a still-excellent headphone.
