The Sony WH-1000XM4C brings back one of the company’s most popular headphone designs with a few worthwhile updates. Sony kept the foldable design, comfortable ear cushions, and familiar 40mm drivers. The new model adds refined sound tuning, Bluetooth 6.0, and a 10-band equalizer. However, its noise-cancellation technology is aging, and its battery life is shorter than the original.
At $299.99, the headphones sit below Sony’s premium WH-1000XM6. They target listeners who value comfort, portability, and enjoyable sound over the latest technology. The main question is whether these improvements justify buying a refreshed design that’s six years old.
Sony WH-1000XM4C Design and Comfort
The WH-1000XM4C keeps the XM4’s familiar look. Its plastic construction, soft synthetic leather cushions, and adjustable headband prioritize practicality. At approximately 253 grams, the headphones remain relatively lightweight for an over-ear model.
The folding design is particularly useful for travel. Both earcups fold inward, allowing the headphones to fit inside their included hard-shell carrying case. This makes them easier to pack than some newer designs with less compact storage.
Sony has made a few subtle changes. The left and right markings are more visible, and the noise cancellation button has a clearer label. Available finishes include Black, Platinum Silver, and Lavender.
Independent testing by What Hi-Fi? praised the familiar construction and comfort during extended listening. However, the headphones have no official water-resistance rating. They suit commuting and office use better than demanding workouts.
Sound Quality and the New 10-Band Equalizer
Sony still uses 40mm drivers, but it has adjusted its sound tuning. Bass remains prominent, while vocals and instruments are better balanced.
The biggest software improvement is a 10-band equalizer in the Sony Sound Connect app. The original WH-1000XM4 offered five bands. The expanded controls let listeners make more precise adjustments across frequencies.
According to Sony’s official announcement, the updated tuning is intended to match modern listening preferences better. That does not necessarily mean every listener will prefer it.
Independent reviewers generally describe the sound as detailed, energetic, and engaging. Bass-heavy music benefits from substantial low-frequency presence. However, listeners seeking a more neutral presentation may want to adjust the equalizer.
The headphones support SBC, AAC, and Sony’s LDAC Bluetooth codecs. LDAC can deliver higher-bitrate wireless audio when paired with compatible devices. DSEE Extreme processing also attempts to restore detail lost in compressed recordings.
Noise Cancellation Remains Effective but Faces Stronger Competition
The WH-1000XM4C uses Sony’s established HD Noise Cancelling Processor QN1. Four microphones help identify surrounding sounds, while the Personal NC Optimizer adjusts cancellation to the listener’s environment.
The system remains effective against steady background noise. It works best against aircraft engines, traffic rumble, and air conditioning. Voices and unpredictable sounds are harder to eliminate.
Independent testing by SoundGuys found strong noise reduction, particularly at lower frequencies. However, newer premium headphones offer more advanced cancellation systems.
Call quality is adequate for everyday conversations, although results vary with environmental noise. What Hi-Fi? reported clear calls and improved wind suppression. Other testing found occasional microphone issues under certain connection conditions.
For buyers comparing alternatives, TechAmerica.ai has also examined the Bose QuietComfort Headphones (2nd Gen). That model emphasizes comfort and noise cancellation, making it a relevant option for frequent travelers.
Battery Life and Connectivity
Battery endurance is one of the more noticeable compromises. Sony rates the WH-1000XM4C for up to 27 hours with noise cancellation enabled. Switching ANC off increases the advertised figure to 34 hours.
The original XM4 offered up to 30 hours with ANC. Sony has introduced a smaller, removable battery in the refreshed model. The change supports newer European battery requirements, although replacement procedures and parts availability can vary by region.
According to Sony’s published specifications, a full charge takes approximately three hours. Actual battery life depends on volume, connected devices, and active features.
Bluetooth 6.0 provides modern connectivity, including multipoint pairing with compatible devices. However, the headphones do not currently support Bluetooth LE Audio or Auracast.
A detachable 3.5mm cable allows wired listening, including passive playback without battery power. The USB-C port is reserved for charging and does not support digital audio playback.
Pricing and Alternatives
Sony launched the WH-1000XM4C in the United States for $299.99. That positions it below the WH-1000XM6 while competing with discounted premium headphones from previous generations.
The newer WH-1000XM6 offers more advanced noise cancellation and additional processing capabilities. However, buyers who prioritize compact storage may appreciate the XM4C’s familiar folding design.
The WH-1000XM5 is another important alternative. Discounted units may approach the XM4C’s price, making it hard to choose between newer noise-cancellation technology and greater portability.
For existing XM4 owners, the improvements are relatively modest. A larger equalizer and revised tuning may not justify replacing headphones that still work properly.
Pros and Cons
Pros:
- Comfortable, lightweight construction with a practical folding design.
- Enjoyable sound with refined tuning and a 10-band equalizer.
- Effective noise cancellation for commuting and everyday listening.
- Bluetooth 6.0, LDAC, multipoint connectivity, and wired playback.
Cons:
- Noise cancellation technology trails newer premium models.
- Battery life is shorter than the original XM4.
- It lacks Bluetooth LE Audio, Auracast, and an official water-resistance rating.
- Discounted newer-generation headphones may offer better value.
Final Verdict
The Sony WH-1000XM4C shows why the original XM4 design remains appealing. Its combination of comfort, portability, strong audio quality, and dependable noise cancellation still works well. The expanded equalizer provides useful customization without complicating the experience.
However, the $299.99 price makes its limitations harder to ignore. Battery endurance has declined, and the noise cancellation hardware is no longer Sony’s most advanced. Buyers can also find newer alternatives at competitive prices.
The WH-1000XM4C is a sensible choice for travelers and music listeners who prioritize comfortable, foldable headphones. Existing XM4 owners have little reason to upgrade unless they need to replace their current pair. Sony has successfully revived a familiar design, but its strongest advantage is refinement rather than innovation.
