Thank you for taking the time to share your concerns and we wanted to provide as much of an open an honest response from our moderation team as possible.
We decided to close the main “ANC thread” for two reasons. The first being that we have confirmed with our engineers that no changes were made to the ANC functionality in the most recent update, we did look into this extensively for you.
The second reason is that due to the atmosphere of the support community, discussion on this topic tends to lead to debates that cannot have a resolution. The topic of measuring noise cancellation is unfortunately vastly subjective and these conversations are difficult to substantiate. We want to protect the community from this divisiveness and potentially creating unnecessary concern for users who were not concerned about their QC35’s initially. Our goal is to avoid any type of an atmosphere of distrust that will negatively impact your experience with Bose since we’ve been unable to get to the bottom of your concerns despite our best efforts.
This issue has been raised in the community after every firmware update since the QC35 Series I was released. Although our engineering teams conduct exhaustive testing on all product functionality before any firmware is released, we wanted to ensure our community members were being heard. Noise cancellation is as important to us as it is to you, so our engineers went back to examine your reports each time they surfaced. Each set of additional testing came back with the same results: That the analysis showed that no intended or unintended changes were made to the ANC performance of the QC35 following these updates.
Our concern is that these debates and discussions can quickly escalate due to the unique online environment. The community has many members and our goals are to provide you with the most accurate and honest information that we can at any given time, foster and promote useful interactions and discussion, and to help make your experiences with Bose products as great as they can be. Unfortunately, this is one topic of discussion we feel we have had very little positive impact on and our users have not seen much benefit from.
