How do I differentiate between the
different sizes of StayHear
®
+ tips?
The StayHear
®
+ tips are color-coded. There is a small colored ring inside
each tip that tells you what size it is.
 White = Small
 Gray = Medium
 Black = Large
This color-coding is the same as other Bose
®
in-ear headphones.
How do the StayHear
®
+ tips provide a
stable fit?
The StayHear
®
+ tips have an extended flexible wing that sits in the bowl of
your ear. They use the ridge of your ear for support and provide
significantly improved stability, while the soft material and rounded profile
delivers a comfortable fit for long-term wear.
How are the StayHear
®
+ tips removed
and replaced on the earbud?
The StayHear
®
+ tips will resist unintentional removal, but can be taken off
by gently peeling up from the large rounded side, ideally near the
bottom.
Caution: Do not pull from the tip wing to remove the tips, as this may
damage them.
To put on another tip, make sure you match the tip to the correct side
earpiece. The tips and the earpieces are marked L and R for your
convenience. Slide the replacement tip over the nozzle of the
headphone. Press the tip securely into place until you feel it latch. The
ridge on the headphone housing should fit into the slot on the inside of
the tip.
How do I put the earpieces in my ears?
First, locate the L and the R on the headset, and match the StayHear
®
+
tips to their corresponding side. Insert the headphone with the opening
toward your ear and the flexible wing pointing upward. The wing of the
tip fits just under your ear ridge.
To put the tip in your ear:
1. Tilt the earpiece forward so it lines up with your ear canal.
2. Insert the earpiece into the ear just enough for it to gently rest against
the entrance of the ear canal. (There is no need to force it into the ear
canal.)
3. Tilt the earpiece back and, if necessary, lightly press the flexible tip wing
under the ear ridge until it is secure.
The tips are designed to rest gently against the opening of the ear canal
and sit comfortably yet securely in the bowl of the ear. They should be the
only part of the headphones in contact with the ear.
