PRODUCT SPECIFICATIONS
OTHER ISSUES
What are the mechanical specifications
of the cables and connector?
Cable length: 5.5 ft./66 in./1.68m
Interface connector: Commercial mini-plug (3.5mm diameter)
What are the noise reduction
specifications? Is there an NRR rating?
Bose Corporation does not provide a noise reduction rating (NRR) or
attenuation specification for our QuietComfort headphones.
The 1970s-era NRR standard for rating industrial hearing-protection devices
was developed long before active noise reduction headphones were
commercially available. In fact, NRR, as defined by the government,
cannot be determined for this product because the test method specified
by law is generally recognized to be inaccurate when applied to active
devices.
Will the QuietComfort 25 Acoustic
Noise Cancelling headphones help
consumers that suffer from tinnitus,
hyperacusis or autism?
Bose Corporation does not make any claims about relief of tinnitus,
hyperacusis or autism, and we have not conducted any long-term clinical
studies of the headphones’ effect on these conditions. Tinnitus,
hyperacusis and autism are complex conditions that are not easily
addressed. Some consumers have reported the headphones improve
their situation, but others have not experienced any improvement.
With the Bose Corporation 30-day trial period, we can suggest consumers
try the QuietComfort 25 headphones personally to see if they experience
an improvement.
