Directions:

Method 1 (Most Common)

Step 1: Deflate Zōk by squeezing the rubber bulb between fingers.

Step 2: While deflated, gently insert Zōk into the outer ear to create an air-tight seal between the Zōk earbud and the ear. This seal should occur just past the entrance to the ear canal—similar to the positioning of an audio earbud. Do not insert the Zōk earbud any further than the entrance to the ear canal. If Zōk causes any discomfort or pain, discontinue use immediately. Maintain the bulb in a deflated state.

Step 3: Maintain Zōk in a deflated state for 20-30 seconds. User will experience a mild sensation of increased pressure.

Step 4: Pinch the Zōk bulb and gently remove from the ear.

Step 5: Perform steps 1-4 for second ear.

Step 6: Repeat 3-5 times, or until pressure or tension in head has eased.

Method 2

Step 1: Without squeezing the Zōk bulb, insert Zōk into the outer ear to create an air-tight seal between the Zōk earbud and the ear. The seal should occur just past the entrance to the ear canal—similar to the positioning of an audio earbud. Do not insert the Zōk  earbud any further than the entrance to the ear canal.  If Zōk causes any discomfort or pain, discontinue use immediately.

Step 2: Partially deflate Zōk by gently squeezing the rubber bulb. Do not fully deflate. Squeeze (partially) and release 5-10 times in each ear. User will experience a mild sensation of increased pressure.

Step 3: Gently remove Zōk from the ear.

Step 4: Perform steps 1-3 for second ear.

Step 5: Repeat 3-5 times, or until the pressure and tension in head has eased.
