ADJUST THE FIT
For the best sound performance and a secure, comfortable
fit, be sure to adjust the headphones to rest gently in your
ear and drape around the back of your neck. 1. Drape the stereo cable behind your neck.
2. Guide one earpiece behind your ear and secure the
eartip inside your ear using the telescoping/swivel
adjustments.
3. Repeat step 2 with the other earpiece and continue
to adjust the fit in each ear until both eartips rest
comfortably and securely in your ears.
