Selecting suitable ear fins and transparent ear tips for optimum fit of the earbuds in the ears

The perceived sound quality including bass performance, the best possible noise cancellation, the best voice quality for phone calls and the secure hold of the earbuds in the ears depend to a large extent on the correct fit of the earbuds. Therefore, you can choose between ear fins and transparent ear tips in different sizes.

Transparent silicone ear tips

Observe the following instructions:

–​Only use the transparent ear tips supplied by Sonova Consumer Hearing to ensure that the sensors for body temperature measurement and heartbeat tracking work properly.

–​If the ear tips are not fitted correctly, the subsequent charging process of the earbuds may be impaired as the charging contacts are not connected to the charging pins in the charging case. In addition, the data collection of the sensor on the left earbud can be distorted.

–​Incompletely fitted ear tips may remain in the ear canal when the earbuds are removed from the ear.

1.​Pull the ear tip away from the in-ear sound tunnel.

2.​Mount the new ear tip to the in-ear sound tunnel. Ensure that it locks into place.

3.​Test which ear tip size gives you the best fit and the best wearing comfort.

You can choose between 3 different ear tips in size S, M and L.

The ear tips should fit securely in the ear canal, close the ear canal completely and be comfortable to wear. We recommend using the largest possible ear tip that fits comfortably in your ear canal.

You can use the Fit Test function in the Smart Control app to test the fit of the earbuds in your ears.

Silicone ear fins

Observe the following instructions:

–​If the ear tips are not fitted correctly, the subsequent charging process of the earbuds may be impaired as the charging contacts are not connected to the charging pins in the charging case.

–​Upon delivery, size M ear fins are attached to the earbuds. When changing the ear fins, first remove the existing ear fins.

You can choose between 4 different ear fins in size N, S, M and L. The ear fin holds the earbud securely in the back of the ear. If you do not want to use an ear fin, put size N (N ring) on the earbud.

Assign the ear fins that you want to attach to the right and left earbud (see embossing on the outside).

To change the left ear fin:

1.​Carefully remove the attached ear fin from the earbud housing.

2.​Position the new ear fin so that the latch on the inside of the ear fin ring is at the level of the corresponding recess of the earbud (a). The oval opening of the ear fin is located at the height of the center bracket (oval protrusion) (b) on the earbud housing.

3.​Slip the ear fin ring over the earbud housing and insert the latch into the recess. The oval opening of the ear fin must enclose the center bracket of the earbud.

4.​Make sure that the ear fin ring fits properly in the groove on the earbud housing.

To change the right ear fin:

1.​Carefully remove the attached ear fin from the earbud housing.

2.​Position the new ear fin so that the two marking points on the earbud and on the ear fin ring are at the same level.

3.​Slip the ear fin ring over the earbud housing and insert the latch into the recess.

4.​Make sure that the ear fin ring fits properly in the groove on the earbud housing.

Test which ear fin size gives you the best fit and the best wearing comfort.

After changing the ear fins, make sure that the earbuds are inserted correctly into the charging case. If the left and right earbud are inserted upside down into the charging compartments, the charging contacts of the earbuds will not make contact with the charging pins in the charging case. This will impair the charging process of the earbuds.
