Dear Valued Customer,
Please note, there were an isolated number of carrying cases packaged with these models that had a small amount of adhesive residue remaining on the inner pocket after manufacturing which may result in mould. Analysis from the testing of the residue by an external laboratory confirms it is unlikely (low risk) to affect human health.
For consumers who have purchased this product, and feel they may be impacted, please contact Panasonic on the toll free number 132 600 (Monday to Friday between 8.30am and 6.00pm) or submit an online contact form by visiting https://www.panasonic.com/au/contact-us.html and we can assist you with an exchange of your headphone and carrying case at no cost. The products were sold from 26 June 2019 until 31 January 2020 in Australia.
On the general area of the pocket indicated below.
