Our commitment to you
We take great pride in designing each of our products with the goal of provid-
ing the highest performance possible in the price range of that product. We strive
to reproduce the musical sounds as closely as possible to those of the original
performance. And we strive to avoid flashy sounds such as those associated with
accentuated bass and/or treble frequencies. While those sounds may be initially
attractive to the novice, they are not real and are not enduring. In addition, we use
only the highest-quality parts and the latest assembly and quality control tech-
niques to ensure the reliability and long life of our products.
Our reputation rests on our steadfast pursuit of this policy in music and entertain-
ment systems for the home, the automobile, and businesses. At Bose, we are
committed to investing in research that continually gives rise to new technologies
for improving sound reproduction.
When you purchase any product from Bose, we encourage you to compare it, as
we do, to competitive products. We believe that this process will enhance your
appreciation of the product you select. With best wishes from all of us at Bose for
many years of enjoyment.

There are several end-plug configurations for the headset. Your headset falls into

comes with an Auto On function.
