If budget is a concern, recent discounts have brought the earbuds closer to the $250 mark.## Redesigned Aesthetics and Enhanced Features

A Fresh Look with Enhanced Discretion

Sony’s WF-1000XM4 earbuds boast a completely redesigned appearance. Departing from the XM3 design, these earbuds have embraced an evolutionary aesthetic that emphasizes practicality. They adopt a more traditional earbud design, ensuring a secure and snug fit for everyday use. While they weigh slightly heavier than their predecessors, their refined profile enhances their discretion, making them an ideal companion for those seeking a low-key audio experience.

Precision Fit and Enhanced Comfort

To cater to a wide range of ear shapes and sizes, the WF-1000XM4 earbuds come with a variety of ear tips, including foam tips for a tighter seal. This adaptability ensures a comfortable fit that withstands even strenuous activities such as running. However, individuals with smaller ears may find the earbuds to be somewhat bulky, as they do not sit flush with your ears like the Samsung Galaxy Buds Live or Google Pixel Buds A-Series.

Distinctive Design and Enhanced Audio Quality

A unique feature of these earbuds is the copper-colored ring that adorns each earbud. While this design element adds a touch of individuality, some may find it somewhat polarizing. Nevertheless, it serves as a visual cue to differentiate these earbuds from competitors. The copper ring houses a microphone, contributing to the improved noise cancellation and call quality of these earbuds. Additionally, bone conduction sensors detect when you’re speaking during calls, activating the Speak-To-Chat feature that automatically pauses your music and switches to ambient sound mode.

Unparalleled Noise Cancellation and Ambient Sound

Sony’s WF-1000XM4 earbuds deliver exceptional noise cancellation performance, effectively blocking out unwanted noise and creating a tranquil audio environment. Their ambient sound mode allows you to interact with the outside world without removing the earbuds, making it convenient to engage in quick conversations or hear important announcements. However, if you tend to sing along to music or talk to your pets frequently, you may want to disable this feature to avoid interruptions.

Enhanced Durability and Call Quality

With an IPX4 water-resistance rating, the WF-1000XM4 earbuds are splashproof, making them suitable for various activities. Furthermore, their touch controls are highly responsive, enabling seamless track navigation and volume adjustments. Additionally, the earbuds feature improved headset performance for making calls. The noise reduction during calls is significantly better than previous models, resulting in clearer and more intelligible conversations even in noisy environments. To enhance your call experience further, a sidetone feature allows you to hear your voice in the buds as you speak, preventing you from talking too loudly on calls.## Excellent Noise Cancellation: A Comprehensive Analysis

Noise Reduction at its Peak

Prepare to be amazed by the exceptional noise cancellation capabilities of these earbuds. Outperforming the XM3 model and competing with the Bose QuietComfort Earbuds, the new Sony WF-1000XM4 sets a new standard in the realm of true-wireless noise suppression.

Sony credits this remarkable improvement to their innovative V1 chipset, which seamlessly processes both audio and noise cancellation. The results are evident in an unparalleled ability to mitigate a wide range of frequencies.

Unrivalled Effectiveness

Our rigorous testing against the Bose QuietComfort Earbuds in a noisy apartment environment revealed surprisingly similar performance, both effectively reducing ambient noise. These earbuds excelled at muffling urban sounds while delivering an impressive sound suppression experience during high-volume NBA broadcasts.

Optimal Seal for Flawless Outcomes

Achieving optimal noise cancellation and audio quality hinges on a snug seal. To ensure this, Sony has meticulously redesigned its ear tips. Included are three sizes of polyurethane-coated foam tips, meticulously sculpted to conform to your ear canals.

Extended Battery Life and Versatile Functionality

Enjoy extended listening sessions with up to eight hours of battery life with noise cancellation activated. Disabling noise cancellation amplifies this to an impressive 12 hours. The charging case further extends the total playtime by a remarkable 16 hours.

Beyond exceptional battery life, the WF-1000XM4 offers a wealth of features via the companion app. Craft your listening experience with adaptive sound modes, comprehensive equalizer settings, and customizable touch controls, including the addition of volume adjustment.

Immerse yourself in the world of voice assistance by selecting from Google Assistant, Amazon Alexa, or your smartphone’s native solution. Furthermore, these earbuds seamlessly play tracks encoded in Sony’s immersive 360 Reality Audio format, available on streaming services like Deezer and Tidal.

Connectivity and Audio Enhancements

Leveraging Bluetooth 5.2, the WF-1000XM4 ensures a stable connection. Additionally, Sony’s LDAC wireless streaming codec elevates audio quality for supported devices and music services.

While these earbuds lack AptX support, most users will rely on the ubiquitous AAC codec for their Bluetooth streaming needs. Our tests using LDAC streaming on a Google Pixel 4 XL revealed a noticeable enhancement in sound quality, particularly for well-recorded tracks.

Notable Considerations

Unlike Sony’s over-ear WH-1000XM4 headphones, these earbuds do not feature multipoint Bluetooth pairing. This limits simultaneous connection to two devices, such as a PC and smartphone, for automatic audio switching during calls.

A Listening Experience That Matters

The WF-1000XM4 earbuds boast exceptional sound quality, effectively revealing the subtle nuances of your favorite recordings. Whether you stream from Spotify or Qobuz, on an iPhone 12 Pro or a Pixel 4 XL, these earbuds will faithfully reproduce the sonic subtleties.


The Sony WF-1000XM4 earbuds set a new benchmark for true-wireless noise cancellation. Their innovative design, long battery life, and exceptional audio quality make them a compelling choice for discerning listeners seeking an immersive audio experience.## Top-notch Sound: An In-Depth Analysis

Embark on a sonic voyage with the Sony WF-1000XM4 true wireless earbuds, renowned for their exceptional audio performance. Each note unfolds with exquisite detail, while the warm and profoundly defined bass resonates deeply. Mids come alive with their natural sound, and the expansive soundstage envelops you in a symphony of delight.

Sony’s relentless pursuit of innovation has led to the development of the V1 chip, a digital processing marvel that enhances the 6mm drivers. The result? A mesmerizing auditory experience that surpasses the acclaimed WF-1000XM3, setting a new benchmark for true wireless sound.

When it comes to defining the essence of audio excellence, terms such as accuracy, articulation, balance, dynamism, and smoothness come to mind. The WF-1000XM4 effortlessly embodies these attributes, delivering an immersive acoustic experience that rivals wired headphones.

Within the true wireless realm, the WF-1000XM4 stands shoulder-to-shoulder with industry titans like Bowers & Wilkins, Sennheiser, and Master & Dynamic. In a direct comparison with Bowers & Wilkins’ PI7 earbuds, the WF-1000XM4 emerged as a formidable contender.

While the PI7 may hold a slight edge in sound quality, the WF-1000XM4’s superior noise cancellation and headset performance, combined with its lower price point, make it a compelling alternative. The choice becomes even more intriguing when you consider that the PI7’s charging case doubles as a Bluetooth transceiver and supports AptX Adaptive.

If a more expansive soundstage is your priority, the Beats Fit Pro might appeal to you. However, the WF-1000XM4’s sound remains more natural, capturing musical nuances with greater precision.

For budget-conscious audiophiles, the Sennheiser CX Plus offers an exceptional balance of sound quality, noise cancellation, and voice-calling performance. Its price point is slightly lower than the WF-1000XM4’s, and its compact size makes it a less bulky option.

Ultimately, the WF-1000XM4 stands as a testament to Sony’s unwavering commitment to exceptional audio experiences. Whether you crave pure sonic indulgence or a versatile companion for music, calls, and noise cancellation, the WF-1000XM4 earbuds are a discerning choice that empowers you to immerse yourself in the world of sound.## FAQs
