Sony WH-1000XM4C Launches With Bluetooth 6.0 and Updated Sound
Sony has introduced the WH-1000XM4C, a second-generation version of its popular WH-1000XM4 wireless headphones. The $300 model keeps the familiar design while adding updated sound tuning, Bluetooth 6.0 and more personalization features.
The original WH-1000XM4 arrived in August 2020 and remained popular even after newer generations entered the market. Now, the WH-1000XM4C builds on that foundation rather than completely replacing it.
According to Sony, the new model has “updated sound tuning designed for today’s listening preferences,”. Additionally, the headphones arrive alongside the $180 WH-CH730N and $80 WH-CH530.
WH-1000XM4C Gets Bluetooth and Sound Upgrades
Visually, the WH-1000XM4C remains almost identical to the original model, apart from minor cosmetic changes. However, Bluetooth receives a significant update, moving from version 5.1 to Bluetooth 6.0.
Moreover, Sony has expanded the equalizer from five bands to 10. A gaming EQ setting also joins the package, offering more control over sound personalization.
Meanwhile, the headphones retain the QN1 chip and four microphones. Therefore, noise-canceling performance remains largely unchanged. By comparison, the premium WH-1000XM6 uses 12 microphones.
Battery life has decreased slightly, though. The WH-1000XM4C offers up to 27 hours with noise cancellation enabled, compared with 30 hours on the original.
Nevertheless, the familiar sound signature remains part of the experience. The original model delivered strong bass and a warmer character than its successors. However, updated tuning now aims to provide cleaner and more refined overall sound.
The headphones also come in three colors. Additionally, a new lavender version joins the range and will have limited online availability.
WH-CH730N Brings Bigger Midrange Improvements
The WH-CH730N represents a more substantial generational upgrade. Its predecessor gained attention for combining lightweight comfort, solid sound and capable noise cancellation at a reasonable price.
However, the new model costs $180, which represents a $30 increase from its predecessor’s original list price. In return, buyers get a new foldable design and improvements across several areas.
Furthermore, battery life reaches up to 50 hours with noise cancellation active. The updated design also feels more premium while maintaining a comfortable fit.
Sound quality improves slightly as well. Although it does not match the clarity and depth of more expensive headphones, the presentation remains open and balanced. Moreover, the bass extends deeply while the overall profile maintains some warmth.
Noise cancellation also receives an upgrade through Dual Noise Sensor technology. According to Sony, it’s about 10% more effective. However, the improvement still does not place the model at the level of the flagship WH-1000XM6.
Voice calling may offer the more noticeable improvement. Specifically, beamforming microphones combine with optimized microphone placement and AI noise reduction to improve call performance.
Additionally, the WH-CH730N includes a 10-band equalizer and gaming EQ. It supports SBC, AAC and the newer LC3 codec, although LDAC support remains absent.
Meanwhile, buyers still get a cable for wired listening. However, the package does not include a carrying pouch or protective case.
WH-CH530 Targets Entry-Level Buyers
At the affordable end of the range, the WH-CH530 brings smaller improvements. The previous CH-520 already offered respectable sound at a low price despite lacking active noise cancellation.
However, the new model costs $80, which is $20 more than its predecessor’s original list price. In return, one of the most notable upgrades is better voice-call performance through AI noise reduction.
Additionally, the WH-CH530 now includes a volume limiter. This feature could make the headphones more appealing to parents buying them for younger listeners.
Battery life is another strength, reaching up to 55 hours. However, the headphones do not support wired listening. Consequently, users cannot connect them directly to traditional in-flight entertainment systems.
Moreover, buyers do not receive a carrying pouch or case. Still, the headphones come in cobalt, coral, mint, pink, white and black.
Pricing could eventually become more attractive across the new range. Headphone list prices have increased, although discounts remain common during major sales periods. Therefore, the WH-1000XM4C and WH-CH730N could become considerably more competitive when promotions arrive.
For now, the WH-1000XM4C offers a familiar flagship experience with selective modern upgrades. Meanwhile, the WH-CH730N delivers broader improvements, while the WH-CH530 focuses on affordable everyday listening.
