Beat the Noise: Noise Cancelling Headphones vs Noise Isolating Headphones

Both noise cancelling headphones and noise isolating headphones are designed to enhance the listener’s experience by reducing unwanted external sounds. While the two technologies are very similar when it comes to this basic goal, there are still some core differences between the two that the more savvy audiophile should be aware of before they make their choice. 

• Noise Cancelling: Noise cancellation is a feature in many headphones that’s been designed to reduce background noise and enhance the audio experience. Active Noise Cancelling (ANC) works by using built-in microphones to detect ambient sounds and then generates sound waves that are the exact opposite of those noises. These opposing sound waves effectively cancel out the unwanted background noise. ANC headphones are ideal for listening to music or podcasts in noisy environments like aeroplanes or buses, allowing you to focus on your audio without distractions. They can also protect your hearing by reducing the need to raise the volume in loud settings and may offer relief for people who suffer from tinnitus.
• Noise Isolating: Conversely, noise isolation is a passive method of blocking external noise. It doesn’t rely on electronics but instead uses the physical design of the headphones to create a seal around or in your ears. This seal acts as a barrier, preventing outside sounds from entering. Noise isolating headphones are excellent for enjoying music in noisy environments, as they provide a natural defence against external noise. By physically blocking out sound, they also help protect your ears from loud, disruptive noises and may reduce tinnitus flare-ups, similar to ANC headphones. 

• Noise Reduction: Noise isolating headphones reduce external noise through their physical design. Their effectiveness depends on the fit and materials, with noise reduction devices forming a tight seal in the ear canal. This passive noise reduction typically decreases mid to high-frequency sounds by about 15dB to 30dB. Conversely, noise cancelling earbuds use built-in electronics to produce sound waves that cancel out ambient noise, especially low-frequency sounds, reducing noise by around 30dB on average. The effectiveness of ANC depends on the quality of the technology, with premium models blocking up to 95% of external noise.
• Sound Quality: Noise isolating devices often deliver better sound quality, as they focus on material and design to produce clear audio without relying on additional electronics. This makes them ideal for audiophiles seeking pure, unaltered sound. Though the process of noise cancelling devices would sometimes alter the audio slightly, subsequent advancements in the technology have minimised these effects, thus maintaining a strong sound performance.
• Power Consumption: Noise isolating devices don’t need batteries or electronics, making them ready to use anytime. On the other hand, noise cancelling devices require regular charging to power their ANC technology, though they still offer some passive noise reduction when the ANC is off.
• Price: Noise cancelling devices are typically more expensive due to the additional ANC technology, while lower-priced models may not perform as well as premium options. Noise isolating devices, without these extra components, are generally more affordable.
• Comfort: Noise isolating devices, especially custom-fitted ones, provide a more comfortable fit since they mould to your ears and distribute pressure evenly. In contrast, ANC devices may cause discomfort over time, as they aren’t custom-fitted and can put uneven pressure on certain areas of the ear.
• Ear Safety: Both noise isolation and noise cancellation are safe technologies, so long as you are listening to your audio at a reasonable volume. Indeed, both technologies can help protect your hearing by allowing you to enjoy your music without needing to increase the volume to drown out background noise. Just make sure you’re aware of your surrounding environments while you’re using them (especially if crossing the road).

Sony WH-1000XM5 Premium Noise Cancelling Wireless Headphones

These exquisite WH-1000XM5 wireless headphones use advanced noise-cancelling technology and multiple microphones to effectively block out high and mid-frequency sounds. Featuring an Auto NC Optimizer, noise cancellation is automatically adjusted based on your environment and wearing conditions. The specially designed 30mm driver unit enhances low-frequency noise cancellation while maintaining sound clarity in high frequencies, thanks to its lightweight carbon fibre composite material. Multi Noise Sensor technology, with four microphones per earcup, dramatically reduces high-frequency noise by accurately capturing ambient sounds. They also use Voice Pickup Technology to ensure ultra-clear calls (even in the noisiest of settings), using AI algorithms trained on over 500 million voice samples to isolate your voice. For convenience, the Speak-to-Chat feature automatically pauses your music and lets in ambient sound when you start talking, resuming playback once the conversation ends.
