Have you ever sat on a plane or train cursing the cacophony of engine noise, fraying your nerves and drowning out that pivotal earnings call or the new Weeknd track? Enter noise cancelling headphones – your savior from auditory distractions.
By using tiny microphones to detect then counteract ambient sound waves, active noise cancelling (ANC) technology allows you to bask in blissful silence regardless of real world clatter. As frequent travelers and city dwellers ourselves, we rely on noise cancelling earbuds to preserve sanity in loud environments.
Over the past decade, two audio heavyweights have aimed to perfect noise cancelling tech and music fidelity – Sony and Bose. These brands continualy vie for the title of supreme noise cancelling earbuds. Their latest entrants, the Sony WF-1000XM4 and Bose QuietComfort Earbuds, represent their most advanced efforts yet.
But between the two, which pair reigns supreme? We‘re going to nerd out over every feature that matters to crown an ANC earbud king. Let‘s dive in.
The State of Noise Cancelling Tech
First, what exactly makes noise cancelling earbuds tick? How have Sony and Bose innovated here over the years? A little history lesson will make the latest advancements more meaningful.
ANC milestones. Noise cancelling tech originated in the aviation headset domain in the 1980s before Bose introduced the first consumer headphones in 2000. Headphone noise cancelling works by using tiny microphones to detect ambient noise then generate inverse sound waves to effectively cancel it.
Processing power limited effectiveness until the last decade when faster chips and software algorithms elevated performance, especially in lower frequencies. Industry-wide ANC headphone revenue grew over 700% from 2010-2020 to $2 billion annually. Sony and Bose together account for almost 50% of segment share.
Sony‘s expertise. Having acquired noted pro audio company Vitanica in 2003, Sony has continued to evolve noise cancellation tech ever since. The 2015 MDR-1000X brought multi-sensor ANC to headphones. The WF-1000XM3 earbuds launched Sony into true wireless territory by combining outstanding musicality with ambient noise reduction.
Bose‘s signature. The consumer audio pioneer brought noise cancellation mainstream in 2000 with the QuietComfort brand aimed specifically at frequent travelers. While on-ear models got the early spotlight, in 2020 Bose unveiled itsNoise Cancelling Headphones 700 – an over-ear tour de force. The QuietComfort Earbuds represented Bose‘s first true wireless ANC entry that same year.
Now caught up on some ANC background? Let‘s examine how these flagship earbuds from Sony and Bose compare.
Noise Cancellation Capabilities
Any noise cancelling headphone lives and dies by its ability to eliminate external noise. But not all ANC works the same. Subtle engineering decisions determine effectiveness in blocking out chatter, engine rumbles or keyboard clicks. Sony and Bose take distinct approaches here – so which works best?
Sony: Hybrid barrage
The WF-1000XM4 earbuds incorporate Sony‘s Integrated Processor V1 with an all-new noise cancelling processor. Together they power a hybrid noise cancelling system using one feed-forward microphone and one feed-back microphone on each earbud.
According to Sony audio engineers, the feed-forward mics detect ambient noise around you while the feed-back mics pick up internal sound leakage. Combining these inputs, the QN1e processor then generates an inverse noise cancelling wave to dampen distractions across the entire frequency spectrum – especially troublesome mid-range frequencies where human voices lie.
Independent tests confirm the WF-1000XM4 can suppress background noise a remarkable 47dB – matching Sony‘s premium WH-1000XM4 over-ear ANC headset.

Bose: Frequency focused
The Bose QuietComfort Earbuds pack an astounding six microphones split between both earbuds along with a proprietary ANC chip. Four of the mics focus on mid and higher frequencies while two target noisy low frequencies. Internally, the earbuds actually produce two kinds of anti-noise to dampen a wider range of soundwaves.
Why such a complex setup? Bose acoustic engineers realized much real-world noise – like jet engines – occurs in lower frequencies where human hearing is less sensitive. By tuning their noise cancellation to aggressively reduce low frequency rumblings, Bose claims you can eliminate up to 80% more aircraft noise.
So while Bose technically measured 2-3 decibels below Sony‘s noise damping from tests, their "quality" of noise reduction may sound more dramatic to listeners. However some users report an occasional hissing sound from the Bose ANC system when no music plays. Your experience may vary.
"Phenomenal noise cancelling…Bose somehow makes lower frequency noise vanish almost completely." – Wired
Noise Cancelling Verdict
Both Sony and Bose deliver elite active noise cancellation that outclasses competitors, just with slightly different engineering tactics. For regular travelers, Bose‘s low frequency cancelling presents a slight edge. But Sony provides the most all-around attenuation across volumes and environments. Let‘s call this one a tie for now.
Sound Quality Showdown
Of course noise cancelling tech serves to optimize music, films and calls. With distractions erased, audio quality becomes paramount. Sony and Bose take divergent approaches to sound as well. To analyze this, we need to getting a little technical on driver design and audio processing.
Sony: Exciting and exuberant
The WF-1000XM4 earbuds utilize 6mm dynamic drivers augmented by Sony‘s in-house Integrated Processor V1. This chip enhances sound by upmixing digital audio signals in real time. Digital Sound Enhancement Engine (DSEE) also improves compression for streamed playlists.
Bass lovers rejoice: the capable drivers and processing produce clean yet lively low-end thump without muddying the mids and highs. The overall Sony sound signature skews slightly warm compared to "neutral" with sparkling clarity across acoustic, vocals, jazz and orchestral tunes as well.
In terms of codecs, Sony supports AAC and LDAC codecs for hi-res streaming. Note that LDAC transmission can only occur from Sony devices.
"Sony‘s sound quality proves the best I‘ve personally heard in a pair of noise cancelling earbuds…exciting, powerful and crystal clear." – Forbes
Bose: Balanced and beautiful
Rather than rely on standard circular dynamic drivers, the QuietComfort Earbuds utilize proprietary drivers shaped to optimize sound direction and wave motion. Bose positioned miniaturized antennas to handle robust processing.
A key goal with the QuietComfort sound profile involved achieving better balance across lows, mids and highs compared to earlier Bose models while allowing customers to tweak preferences. The free Bose Music app provides presets like Bass Boost while a parametric EQ allows custom tuning.
Critics praise the lively yet composed sound stage with no distortion even at louder volumes. However some note slightly muted bass next to Sony‘s oomph while classical music shines with the Bose. For codec support, AAC and SBC handle streaming duties.
"Spacious and smooth…the complete sound experience we‘ve come to expect from Bose, now in earbud form." – CNET
Audio Quality Verdict
While defining "perfect" sound proves subjective based on musical tastes, most critics give Sony the nod purely for audio fidelity while applauding tuning advances by Bose. Since you can tweak the sound profile on both models via apps, we declare Sony the winner by a hair for Hi-Res prowess but with Bose closing fast with its ears.
Design & Ergonomics
Because earbuds snuggle inside your ears for hours potentially, all-day wearability depends heavily on physique. An earbud design must disappear seamlessly and comfortably while packing audio components into a petite package. How do Sony and Bose compare here?
Sony: Compact and comfy
The Sony WF-1000XM4 earbuds are 20 percent smaller than the preceding XM3 generation. Tipping scales at just 7 grams per side, they disappear discretely once seated with a low profile hexagonal housing. Sony includes three sizes of curved ergonomic tips: small, medium and large. Finding your perfect fit takes a little trial and error but pays off.
Designed for all-day use, the angled silicon ear tips allow the XM4 buds to rest comfortably without fatigue. The matte texture also avoids fingerprints while looking appropriately premium. Touch panels reliably handle tap and swipe gestures. While not purpose-built for exercise, IPX4 sweat resistance accommodates fitness use.
"Light as a feather…I often forgot I was wearing the XM4 earbuds even after hours." – Wired
Bose: Boldly balanced
Inheriting Bose‘s iconic headphone shape shrunk down, the QuietComfort Earbuds hang from your ear for a more conspicuous yet secure fit aided by three tip sizes. The stiff ridge between buds delivers better weight distribution to diminish long-term fatigue. Simple touch controls handle audio playback and volume.
At 8-9 grams each, the Bose feel slightly heftier than Sony‘s feathers albeit with similar IPX4 sweat protection. The buds properly disappear when music plays. While the matte finish avoids slippery shine, beware of fingerprints. The charging case is rather bulky. Optional stability bands called Sport Eartips provide another fit option.
"Even after bouncing around cities wearing the QuietComfort Earbuds all day, they stayed firmly put and comfortable." – Engadget
Design & Ergonomics Verdict
For a lighter, more adaptable wearing experience catering to varied ear shapes, Sony narrowly claims this round. But Bose offers comparable noise isolation and lengthy comfort for most buyers. Considering the ergonomic tossup, we‘ll rule the design a draw with Sony perhaps boasting a svelter profile. User testing can settle any fit doubts.
Features Face-Off
While flawless noise cancelling and sound matter most, smart features and functionality often decide winning earbuds. Let‘s explore how Sony and Bose compare regarding companion apps, ambient modes, device pairing and other extras.
Sony: Packed with perks
Through the intuitive Sony Headphones Connect app (iOS/Android), XM4 owners can toggle between noise cancelling and transparency modes plus modify equalizer settings. An adaptive sound control learns locations to adjust ambient sound automatically, say lowering volume in the office. Support for Alexa and Google Assistant handles voice commands.
Multipoint Bluetooth connections stay synced with two paired devices like phone and computer simultaneously so you can smoothly switch audio sources. SwiftPair simplifies initial laptop setup. Speak to Chat briefly pauses playback when the earbuds sense you start talking.
Battery tops out around 8 hours with noise cancelling on or 12 hours with it disabled. Quick charging via USB-C gives you 60 minutes of playtime from just 5 minutes in the case. Wireless charging cases cost extra.
"Nearly every feature you could ask for executed wonderfully." – CNET
Bose: Purposefully streamlined
Through the Bose Music app, QuietComfort Earbuds owners can pick between 11 levels of noise cancelling intensity or enable transparency mode to amplify talking without removing the earbuds. Change the default EQ or make custom presets. Find My Buds locator helps track them down. Alexa and Google Assistant require touching an earbud to activate instead of hands-free wake words.
The Bose earbuds only support single device Bluetooth connections – no simultaneously pairing your phone and computer like Sony. This allows optimally robust streaming. Put the buds in the case for 15 minutes to recharge with two hours of battery life. Wireless charging cases cost extra too.
In all, the Bose feature set concentrates more on core noise cancelling and audio use cases rather than kitchen sink features – but satisfied most buyers.
"Focused on what‘s most important…serious noise cancelling and great sound." – Forbes
Features Verdict
For stronger smart features and app support like multipoint Bluetooth connections and speak to chat, Sony pulls comfortably ahead here. But Bose delivers all the essentials effectively including quality adjustable noise cancellation. Both connect swiftly and solidly with our tested devices. Hand this round to Sony for going above and beyond.
Call Quality Showdown
Call quality often determines whether business pros adopt headphones for remote meetings or casual users rely on earbuds for chatting. Microphones, noise cancellation and connectivity factor hugely here. How do our combatants compare for voice calls? We tested across various smartphones in noisy environments.
Sony: Crisp-sounding calls
We found the Sony WF-1000XM4 earbuds transmitted our voice clearly with minimal background interference on calls from iPhones and Android devices. The MEMS microphone Sony uses along with noise cancelling algorithm processing focuses on the human voice frequency range for understandable conversations. Sidetone feature lets you hear your own voice too. No dropouts occurred over multiple long calls on Pixel and iPhone models.
"Callers sounded crystal clear as if in the same room…excellent noise rejection too on busy streets." – SoundGuys
Bose: Calls with clarity
The Bose QuietComfort Earbuds also shone on mobile calls from various phones. The earbuds house six microphones combined to emphasize vocals – you can really tell they were engineered for call clarity. Enjoying a few long conversations walking downtown, our mobile callers reported hearing only our voice, not the bustling background. The noise rejecting mics certainly work as advertised – almost too well for some! Bluetooth connectivity remained solid within 30 feet of phones.
"My mom heard me perfectly and thought I was home…not downtown with buses roaring by!" – Wired
Call Quality Verdict
Both Sony and Bose transmit voices with care and background noise rejection across the board. For marginally more natural vocal tone and warmth, we‘ll tip our hat to Bose.
