Sony WH-1000XM6 vs Bose QuietComfort Ultra 2: Comparison Review

The competition for the top position in the active noise canceling (ANC) headphone market has narrowed to a comparison between the Sony WH-1000XM6 and the Bose QuietComfort Ultra Headphones (2nd Gen). Both flagship models are priced at a manufacturer’s suggested retail price (MSRP) of $449.99 and focus on maximizing comfort and ANC performance for long-term use.

According to reporting from SoundGuys on October 4, 2025, both devices feature foldable designs and include airplane-friendly travel cases that support lay-flat storage.

Sony WH-1000XM6 Technical Specifications and Performance

The Sony WH-1000XM6 utilizes Bluetooth 5.3 and supports several codecs, including SBC, AAC, LDAC and LC3. The device weighs 254 grams and is available in three different finishes.

What Hi-Fi? describes the audio performance of the WH-1000XM6 as wonderfully detailed, spacious and musical sound with a great sense of dynamism. The headphones provide 30 hours of battery life and are noted for having an excellent microphone and strong device compatibility.

While the ANC is described as effective with a natural effect, the device has specific limitations. Both SoundGuys and What Hi-Fi? report that the WH-1000XM6 does not support audio listening via USB-C and lacks an ingress protection rating.

Bose QuietComfort Ultra (2nd Gen) Technical Specifications

The Bose QuietComfort Ultra Headphones (2nd Gen) feature Bluetooth 5.4 and support SBC, AAC, and aptX Adaptive codecs. They weigh 250 grams and are offered in five finishes.

A key technical advantage for the Bose model is the inclusion of USB-C lossless audio. The device also introduces a new spatial audio mode. However, SoundGuys notes that users may encounter some connection issues and that the in-app EQ is a negative point.

Battery life reports for the Bose model vary between sources. Tom’s Guide reports 24 hours of battery life, while What Hi-Fi? lists the battery life as 30 hours. Like the Sony model, the Bose headphones do not have an IP rating for ingress protection.

Comparative Analysis of ANC and Sound

Both headphones are positioned as leaders in noise cancellation. In a long-term test published on January 27, 2026, Tom’s Guide noted that while the Bose headphones initially seemed to block more noise, the Sony WH-1000XM6 eventually became the preferred choice for the reviewer due to its customizable sound and overall performance.

What Hi-Fi? concludes that the Sony WH-1000XM6 remains the class leader at this premium price point, despite the Bose model offering significant improvements in sound quality over its first-generation predecessor.

The primary trade-offs between the two models include:

• Connectivity: Bose offers Bluetooth 5.4 and USB-C lossless audio, while Sony uses Bluetooth 5.3 and lacks USB listening.
• Audio Profiles: Sony is praised for detail and dynamism, while Bose is noted for its spatial audio mode and improved sound quality over the previous generation.
• ANC: Both provide top-tier noise cancellation, with Bose often cited for its ability to block nearly everything and Sony noted for a more natural effect.
• Physical Design: Both are foldable, though What Hi-Fi? reports that the Sony model does not fold as neatly into its case as the Bose model.

On February 15, 2026, a review via YouTube suggested that while both are the best options in the ANC market, the Bose model slightly edges out the Sony in sound, though this contrasts with the findings of What Hi-Fi? and Tom’s Guide.
