To that end, Bose has posted a forum thread where customers can discuss the latest report. The company took a long time to address the initial buildup of complaints, but itвЂ™s hard to argue that Bose didnвЂ™t put in some serious work here. Take it all in, and I think this is a pretty commendable job from Bose in trying to hunt down whatever problem has been frustrating people. It also made the above video for troubleshooting noise cancellation problems. вЂњIf you wish to take advantage of this downgrade option, we advise you to do so as soon as possible,вЂќ Bose said, and the company said it encourages all customers to remain up to date on the latest firmware. QC35II owners can downgrade to 4.3.6, and the original QC35 can go back to 2.5.5.

In response to all of this, Bose is updating its testing procedures, improving its firmware update website, and (temporarily) giving customers the option to downgrade if they so choose - even while insisting that firmware was never the problem. Once again, the firmware update 4.5.2 was not found to be the cause of any degradation in overall noise reduction performance.вЂќ

вЂњOur full engineering analysis determined that the degradation in all cases was the result of hardware related issues with ear cushions, aftermarket parts, or mechanical integrity. Third-party ear cushions were also found to вЂњnegatively impact passive reduction performanceвЂќ and put the headphones out of spec, and Bose also noticed that some units from customers had mechanical damage - likely from everyday wear and tear. In the few small cases where it did find a measurable difference in noise canceling quality, the company says the ear cups werenвЂ™t fully snapped on Bose says missing even one of the 10 tabs can make a difference. So whatвЂ™s the problem, then? ThereвЂ™s got to be something going on that created this chorus of complaints, right? Well, Bose has an explanation. So it went further and sought out independent testing through вЂњa third-party acoustics test laboratory.вЂќ Again, the updated 4.5.2 firmware showed no signs of being the culprit behind degraded noise cancellation.

Some of the hardware that Bose used to test the QC35 and QC35II headphones. вЂњThis robust evaluation of customer-returned units did not reveal any issues with noise cancellation performance, and Bose was not able to replicate the concerns of our customers,вЂќ the report says. The company conducted extensive lab testing and went so far as to visit some customers at home to observe them using the QC35 and QC35II headphones. вЂњThrough all of our investigation and testing, weвЂ™re confident that firmware 4.5.2 did not affect the noise cancelling feature.вЂќ вЂњWhen we launched QC35 I and II, we set stringent specifications for noise cancelling performance,вЂќ the company wrote in its report. But itвЂ™s going to let QC35 owners downgrade back to older firmware if they want to, which is an option that the company had previously supported, but later pulled amid all this controversy.ДЄs noted by Gizmodo, Bose published a long, in-depth forum post about its findings on Thursday. After spending months looking into reports of reduced NC performance - something many customers have blamed on firmware updates - Bose has concluded that firmware isnвЂ™t responsible for the perceived drop in noise cancellation effectiveness.
