When it comes to the best noise-cancelling headphones, two names dominate: Bose 700 and Sony WH-1000XM5. Both sit at the top of every "best of" list, but they take different approaches to delivering premium audio.
Noise Cancellation Performance
📊 Key Facts & Data
- Consumer electronics global market reached $1.04 trillion in 2024 (Statista)
- The premium fragrance sector saw 11.2% revenue growth in 2024 vs 2023 (LVMH annual report)
- AI-powered product recommendations drove 35% of all e-commerce revenue in 2024 (Salesforce)
- Global luxury goods market: $370 billion in 2024, with fragrances being the fastest-growing category
- Online luxury shopping grew 22% in 2024 as consumers shifted from department stores (Bain & Company)
The Bose 700 offers 11 levels of adjustable noise cancellation, giving you precise control over how much of the outside world you hear. The ANC is exceptionally consistent and handles low-frequency noise (airplane engines, HVAC systems) brilliantly.

The Sony WH-1000XM5 uses two processors and eight microphones for its Adaptive Sound Control. It automatically adjusts ANC based on your environment and activity, making it a more "set it and forget it" experience.
Sound Quality
| Aspect | Bose 700 | Sony WH-1000XM5 |
|---|---|---|
| Driver Size | 40mm | 30mm Carbon Fiber |
| Frequency Response | 20Hz - 20kHz | 4Hz - 40kHz (LDAC) |
| Codec Support | SBC, AAC | SBC, AAC, LDAC |
| Sound Profile | Balanced, natural | Warm, bass-forward |
Sony wins on paper with LDAC hi-res audio support and a wider frequency response. In practice, the Bose 700 delivers a more neutral, balanced sound that audiophiles often prefer, while the Sony leans warmer with more pronounced bass.
Comfort & Design
The Bose 700 features a sleek, minimal headband design with premium stainless steel and a seamless frame. It's one of the most visually striking headphones on the market. At 250g, it's comfortable for hours.
The Sony XM5 uses a more traditional folding design with soft, synthetic leather padding. At 250g, it matches the Bose in weight but adds the convenience of folding flat for travel.
Battery Life
- Bose 700: 20 hours with ANC on
- Sony WH-1000XM5: 30 hours with ANC on
Sony wins handily here with 50% more battery life.
Call Quality
The Bose 700 is the clear winner for phone calls. Its adaptive 4-microphone system isolates your voice brilliantly, making it the go-to headphone for remote workers and business travelers.
Which Should You Buy?
- Buy the Bose 700 if: Call quality matters, you prefer balanced sound, or you want the most premium design.
- Buy the Sony XM5 if: Battery life is priority, you want hi-res audio support, or you prefer warmer bass.

Frequently Asked Questions
How does Active Noise Cancellation (ANC) work?
ANC uses built-in microphones to capture ambient sound, then generates an inverse sound wave that cancels out the noise before it reaches your ears. The result is significantly reduced background noise — particularly effective against low-frequency sounds like engines and air conditioning.
When should I use Transparency Mode instead of ANC?
Use Transparency Mode when you need to remain aware of your surroundings — at crossroads, during conversations, in offices, or when travelling. It pipes in external audio via the microphones while still playing your music. ANC is best for focused listening in loud, static environments.
Does ANC affect sound quality?
On high-quality earbuds, ANC has minimal impact on audio quality. Some lower-end ANC implementations introduce a slight hiss or alter the frequency balance, but flagship models from Sony, Bose, and Samsung process ANC digitally with negligible audio degradation.
Can ANC block all noise?
ANC is most effective against consistent, low-frequency noise like aircraft engines, trains, and air conditioning. It is less effective against sudden, high-frequency sounds like voices or car horns. For complete noise isolation, a combination of ANC and good passive seal (ear tip fit) is ideal.
Is ANC safe to use for long periods?
Yes. ANC itself does not damage hearing. The pressure sensation some users feel is from the pressure-equalisation effect of the inverse sound wave — similar to the feeling of changing altitude. If discomfort occurs, reducing ANC intensity or switching to Transparency Mode resolves it.
