Care and maintenance of the earbuds/charging case

MOMENTUM True Wireless 2 | 33

Care and maintenance of the 
earbuds/charging case

Only clean the charging case with a soft, dry cloth.

Clean the earbuds with a slightly damp cloth.

Clean the charging contacts on the earbuds and in the charging 
case from time to time using e.g. a cotton swab.

If the earbuds have gotten wet:

Remove the ear adapters and dry the earbuds and ear adapters 
with a dry cloth. If necessary, leave the earbuds and ear adapters 
dry at room temperature for approx. 24 hours.

Replacing the ear adapters

For reasons of hygiene, you should replace your ear adapters from 
time to time. Spare ear adapters are available from your Sennheiser 
partner.

1. Pull the ear adapter away from the in-ear sound tunnel.

2. Mount the new ear adapter to the in-ear sound tunnel. Ensure that

it locks into place.
