Sonos admits a mistake, but in a favorable manner: Improved audio quality now found on Sonos speakers
In early August 2025, Sonos speakers experienced a change in sound quality, according to multiple users on the r/sonos subreddit and social media platforms. The change was characterized by an increased boominess of the bass on all speakers, leading to speculation and debate among users.
Initially, Sonos spokesperson KeithFromSonos stated that the latest firmware update had no changes to the audio or sound profile. However, after further investigation, Keith admitted that there were DSP fixes in the update that improved the speakers' sound quality.
Despite Keith's initial denial, many users noticed a significant improvement in their Sonos speakers' sound after installing the latest firmware update, which was released around August 6, 2025. The r/sonos subreddit was divided, with some users claiming that their speakers sounded better, while others believed it was a placebo effect.
The phenomenon led to speculation about software tweaks impacting user perception, but KeithFromSonos insisted that the DSP fixes affected how lower frequencies were being represented. Other Sonos users, such as Flamiatos and Rampy RS, also noticed the change in sound quality.
Sonos has introduced legitimate sound-related updates for some products earlier in 2025, such as improved AI-driven speech enhancement for the Sonos Arc Ultra, which enhances dialogue clarity via software. However, the company has not officially admitted to making a firmware update that improved the sound quality of their speakers recently.
Industry coverage noted that Sonos quietly rolled out this firmware update related to customer experience improvements, but the company initially insisted there were no sound changes despite widespread perception to the contrary. Some users have reported adjusting their bass settings as a result of the change in sound quality.
The situation on the r/sonos subreddit resembles a Reservoir Dogs-style standoff, with users passionately debating the change in sound quality. The best wireless speakers from various brands have been compiled in a separate article, while the best Bluetooth speakers for the year 2025 have been updated in a separate article. The r/sonos subreddit may need to reconsider its stance on the sound quality change, as it was based on the information provided by Keith initially.
Interestingly, Sonos may have realised a marketing benefit by letting users believe there were improvements in the firmware update, especially considering the upcoming price hikes, which are set to arrive at some point this year. The best Sonos speakers and soundbars, as rated by experts, can be found in a separate article.
The latest firmware update potentially improved the sound quality of Sonos wireless speakers, as reported by various users, leading to increased debate on the r/sonos subreddit and social media platforms. This update also raised questions about how technology can influence user perception, especially when it comes to smart-home devices and gadgets like Sonos speakers. Moreover, the controversy might have unintentionally created a marketing opportunity for Sonos, given the impending price hikes for their products.
