Your custom earphones are made of soft, flexible silicone for a secure fit. They need to be fully inserted deep into your ear canals to achieve the tight seal they were designed to achieve. With a little practice, inserting your earphones will become quick and easy. Just follow these simple steps. (NOTE: Earphones in these photos are Sensaphonics ProPhonic 2X-S.)

STEP 1
Hold the earpiece with the blue or red dot on top (blue dot = left ear, red = right). The cables will run over and behind your ears.

STEP 2
Place the canal portion of the earpiece into your ear canal.

STEP 3
Rotate the earpiece toward the back of your head as you push the earpiece in.

STEP 4
Make sure top portion of earpiece is tucked in. If the earpiece is not all the way in, you will not have a good seal and will lose isolation and bass response. See Step 5 photo for correct placement.

STEP 5
Once inserted, don't be afraid to push on the canal portion of the earpiece to make sure it is all the way in. You may find it helpful to pull back on your ear while pushing the earpiece in.

STEP 6
Bend the "memory wire" cable tightly around the top of your ear. Adjust the length of the cable ends by moving the zipper (split adjuster) up and down where they meet.

REMOVAL
Never pull on the cable to remove your earphones! Instead, reach behind the earpiece at the bowl of the ear and twist the earpiece toward the front as you remove it. Simple!

SEAL TEST
As with all isolating earphones, your 3D earpieces must be fully inserted to create a deep, tight seal. A poor seal will result in a loss of bass response and lack of isolation. To confirm that you have a full seal, use our downloadable audio seal test.
