If you own a Cambridge Audio YOYO (M) portable Bluetooth speaker system, stop using it.
Cambridge Audio has issued a voluntary product safety recall covering every YOYO (M) because its rechargeable lithium-ion battery can overheat and enter thermal runaway. According to Cambridge, affected products can catch fire, emit smoke and eject hot battery material, including while being charged.
The recall is unusually broad. It does not apply to one production batch or a specific serial-number range. Every YOYO (M) sold between 2016 and 2023 is included, regardless of purchase date.
Cambridge says it has received a small number of reports involving batteries overheating during charging and resulting in fire and/or smoke. The company says no injuries have been reported.
Which Cambridge Audio YOYO Speakers Are Recalled?
The recall applies specifically to the Cambridge Audio YOYO (M) in all three color versions:
Color Model Reference UPC Light Grey C10930 813371022959 Dark Grey C10931 813371022966 Blue C10965 813371024922
Cambridge also identifies the corresponding serial-number prefixes as FD C10930, FD C10931 and FD C10965. The model information can be found on the bottom of the speaker.
The recall does not currently include the YOYO (S) or YOYO (L).
What Is Wrong With the Battery?
The YOYO (M) contains an internal rechargeable lithium-ion battery that Cambridge says can overheat and enter thermal runaway.
Thermal runaway occurs when rising battery temperature triggers reactions that generate still more heat. In severe cases, a lithium-ion battery can produce smoke, flames and extremely hot material.
Cambridge says the reported incidents occurred during charging. France’s official RappelConso product recall database also states that examples of the product have caught fire while being charged.
Cambridge says the YOYO (M) met applicable safety standards when it was designed and manufactured. After receiving reports years later, the company decided it could not identify a reliably safe subset of products and recalled the entire model line.
What Should YOYO (M) Owners Do?
Cambridge’s instructions are straightforward:
- Stop using the YOYO (M) immediately
- Switch it off and disconnect it from power
- Do not recharge it
- Store it away from combustible materials
- Do not open the speaker or attempt to remove the battery
- Do not attempt a repair
- Do not put it in household trash or ordinary recycling
- Do not ship it back using regular mail or an ordinary courier
Lithium-ion batteries require specific transportation and disposal procedures, so owners should wait for instructions applicable to their country.
This is not a DIY battery-replacement project. Leave the screwdriver in the drawer.
What Should U.S. Owners Do?
As of August 25, 2026, Cambridge Audio has announced the safety recall but has not yet finalized the remedy for customers in the United States.
That means Cambridge has not confirmed whether U.S. owners will receive a refund, replacement or another form of compensation.
U.S. customers should register through Cambridge Audio’s recall support system so the company can contact them when the process is finalized. Owners should not independently mail the speaker back or dispose of it while waiting for those instructions.
Cambridge Audio YOYO (M) Recall Information
What About Owners Outside the United States?
The remedy varies by market.
In the United Kingdom, Cambridge has notified Trading Standards and the Office for Product Safety and Standards and is asking owners to complete its YOYO (M) Assessment Form.
In the European Union, Cambridge has notified the relevant safety authorities, including the EU Safety Gate system and France’s RappelConso service.
France’s government recall database currently lists a refund as the compensation method and specifies that returns must use transportation suitable for lithium-ion batteries.
Cambridge says procedures are still being finalized in a number of other markets, including Canada, Australia, Japan, Israel and New Zealand.
Why This Recall Matters
The YOYO (M) was sold for roughly seven years, from 2016 through 2023.
That matters because many of these speakers may no longer be in the hands of their original buyers. Portable audio products get moved between rooms, handed down to family members and forgotten in closets until someone decides to charge them again. Owners therefore shouldn’t assume an older YOYO (M) has escaped the recall simply because it has worked without problems for years.
The model designation is what matters.
The Bottom Line
Cambridge Audio’s YOYO (M) recall requires immediate attention because the potential failure involves an internal lithium-ion battery and the risk of fire.
If you own one, switch it off, disconnect it and follow Cambridge Audio’s recall instructions for your country. Do not charge, open, ship or dispose of the speaker until Cambridge provides the appropriate procedure.
For U.S. customers, the remaining unanswered question is compensation. Cambridge has not yet announced whether owners will receive a refund, replacement or another remedy.
We will update this story when that information becomes available.
