Audio-Technica Charging Case For Wireless Headphones

ATH-CK3TW BK 4961310152277
ATH-CK3TW BL 4961310152284

The lot number is printed on a sticker on the inside of the lid of the charging case. If the number on this sticker ends in “B”, the charging case is not in scope of the recall.

The fault identified relates to a runaway issue. It has been reported that the charging case can heat to the point of melting, causing smoke to be produced and the case could then be at a risk of igniting. The product does not meet the requirements of the Electrical Equipment (Safety) Regulations 2016.

Should I stop using my CK3TW even if I have not experienced any problems?
Yes. Although the actual CK3TW earbuds pose no risk, you should stop using the charge case with immediate effect – even if no problems have been experienced to date with it. Once Audio-Technica send you a free replacement charging case, you may continue to use and charge your complete product as before, without risk.

Does my charging case now pose a spontaneous fire risk and is it dangerous?
Yes.  The charging case poses a fire risk when connected to power via the USB cable and whilst containing the earbuds inside the charging case. To stay safe, therefore, please do not place the charging case onto charge and remove your earbuds from the charging case.

The lot number on my sticker has faded / been damaged, if it operates as expected can I assume that it had a lot number ending in a “B” and I do not need to return?
No. If you either do not have the lot number sticker present or cannot read the lot number anymore, please err on the side of caution and arrange for the return and replacement of your charging case as advised.

Will I need to send back my CK3TW earbuds as well as the charging case?
No. You do not need to send back or replace the CK3TW earbuds. Only the charging case is affected by the fault. Please keep the earbuds in a safe place until you receive the replacement charging case.

Will the replacement charging case be compatible with my CK3TW earbuds no matter how long ago I purchased them?
Yes. The replacement charging case will work with all CK3TW models.

I purchased my CK3TW from a retailer, do I need to return it to them to get my replacement case?
No. If you are based anywhere within the European Union or the UK, we can replace your charging case directly and completely free of charge.

Can I keep my CK3TW charging case as a spare if it has not experienced these issues?
No. We will require the return of the affected charging cases in order to issue your replacement. We are recalling these charging cases as an important safety measure. We want to ensure there is no risk to you when using any of our products. Therefore, we will not be able to allow you to keep one of the affected charging cases, even if no problems like the one reported have been experienced.
