As soon as extra, the firmware change 4.5.2 was as soon as not stumbled on to be the motive for any degradation in total noise prick rate performance.”Īccording to all of this, Bose is updating its testing procedures, bettering its firmware change web web page, and (temporarily) giving customers the choice to downgrade if they so bag - even whereas insisting that firmware was as soon as never the anxiousness. “Our fleshy engineering diagnosis determined that the degradation in all cases was as soon as the tip end result of hardware connected considerations with ear cushions, aftermarket ingredients, or mechanical integrity. Third-party ear cushions were also stumbled on to “negatively affect passive prick rate performance” and attach the headphones out of spec, and Bose also seen that some devices from customers had mechanical damage - seemingly from on an on a normal basis basis attach on and toddle.
Within the few limited cases the set it did gain a measurable distinction in noise canceling quality, the firm says the ear cups weren’t fully snapped on Bose says lacking even among the ten tabs can hang a distinction.

After spending months taking a behold into experiences of diminished NC performance - something many customers hang blamed on firmware updates - Bose has concluded that firmware isn’t accountable for the perceived fall in noise cancellation effectiveness.
