Performance

The real magic of the WH-1000XM4 lies in its audio performance and noise cancellation capabilities, which continue to raise the bar in the industry.

Sound Quality

The audio reproduction is warm, full-bodied, and detailed across the spectrum. The DSEE Extreme processor, co-developed with Sony Music Studios Tokyo, intelligently enhances compressed audio formats like MP3 or Spotify streams to near high-resolution quality.

Bass is rich but not overpowering, mids are crisp and clear, and highs are well-detailed without being piercing. The headphones support LDAC, Sony’s proprietary high-resolution wireless codec, ensuring audiophiles can get the most out of hi-fi tracks when paired with a compatible device.

Noise Cancellation

Sony’s Dual Noise Sensor Technology and QN1 Noise Canceling Processor work harmoniously to analyze and cancel ambient sounds in real-time. Whether on a plane, in a busy café, or near traffic, the ANC performance is excellent — arguably still the best in the consumer market.

• Wind noise and low-frequency rumble are significantly reduced.
• Voices and mid-frequency distractions are managed decently, though some leakage may occur compared to newer competitors.

Comfort and Design

The WH-1000XM4 looks nearly identical to its predecessor but brings subtle ergonomic improvements:

• Softer, more cushioned earpads
• Lighter frame for reduced fatigue
• Headband redesigned to better distribute pressure

This makes it highly suitable for extended listening — whether it’s a long-haul flight or all-day office use.

Connectivity and Smart Features

Sony has addressed a major shortfall in the XM3 by adding multipoint Bluetooth connection, allowing the user to stay connected to two devices simultaneously — like answering a call on your phone while watching a video on your laptop.

The Speak-to-Chat feature uses onboard microphones and AI to detect when you begin speaking, automatically pausing playback and resuming after the conversation ends. This works well but can be overly sensitive for users who occasionally talk to themselves or cough.

The wear detection sensor also enhances usability by pausing music when you take the headphones off and resuming once worn again.

Customer Feedback

Sony WH-1000XM4 has generally received glowing reviews, though not without some critical feedback. Here’s a breakdown based on user reports.

Positive Feedback

Aspect	Feedback Summary
Sound Quality	Clear, balanced, immersive; praised by audiophiles and casual listeners alike.
Noise Cancellation	Outstanding, especially for low-frequency sounds; ideal for travel and focus.
Comfort	Lightweight and suitable for prolonged use.
Smart Features	Useful features like Speak-to-Chat and wear detection appreciated by tech-savvy users.
Call Quality	Clear and consistent in most environments, though some distortion in wind is reported.

Mixed or Negative Feedback

Aspect	Feedback Summary
Battery & Charging	While many praise the 30-hour battery, some units reportedly stop charging after a month of use.
Build Quality	Mostly plastic; some users expected more premium materials for the price.

In essence, when the WH-1000XM4 works well, it’s nearly flawless. However, a minority of users have experienced hardware issues within the first few months, particularly related to charging and ANC malfunctions.
