Importance of Proper Fit

For effective noise reduction performance, it is important to choose the correct size StayHear^® + tip.

Select the size that gives you the best comfort and fit in each ear. You may need to try all three sizes to determine the best fit.

To test the fit, try speaking aloud (with the power off). Your voice should sound muffled in both ears. If not, select another tip size.

Each tip is marked with either an L or an R. Be sure to attach the left tip (L) to the left earpiece and the right tip (R) to the right earpiece.

3. To change a StayHear® + tip:
   1. Gently peel the edges of the attached tip away from the earpiece, using care not to tear the tip.
      
      To prevent damage, do not pull on the tip wing.
   2. Slide the new tip over the headphone nozzle.
   3. 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.
4. Fitting the headphones to your ear
   1. Insert the headphone into the ear so the tip gently rests in the opening of the ear canal.
   2. Tilt the headphone back and lightly press the wing under the ear ridge until it is comfortable and secure. The tip should sit comfortably yet securely in the bowl of the ear.
