Ts for using your Stetho properly

1.Align the headset

Before placing the earts in your ears, make sure they point forward, away from you. (Figure A) This ensures that the eartubes will align with your ear cs for comfort and maximum sound transmiion. Holding the headset in front of you with one eartube in each hand, pull the headset open and place the earts into your ears. (Figure B)

If the fit isn't comfortable, or acoustic performance is lacking, adjust the headset tension. All our stethos feature adjustable headsets. Gently the eartubes together to increase headset tension; pull them apart to decrease tension.
