Both Lightning and USB-C devices can be charged and have headphones used simultaneously despite the lack of a 3.5mm headphone port.
This can be done with relatively cheap adaptors which allow 2 x lightning, or 2 x USB-C to be connected to the single port, one for headphones and one for power, or adaptors that have 1 x lightning/USB-C for charge and 1 x 3.5 port for headphones that connect to a single USB-C.
The Lightning devices are sold by Apple on their website, and through their retail stores, even though they are not Apple brand, they are Belkin.
Belkin also makes USB-C devices as described.
I am sure that there are lower-cost & probable more expensive devices available but, I tend to avoid cheap, unknown brands or unbranded devices at all costs. Belkin for example has been around since I have been involved in computing, in the 80's making PC accessories.
There was a "teardown" done by a reputable organisation, I can't recall if it was the IET or Electrical Safety First that did it, but it compared a genuine Apple lightning power supply and an unbranded one found on one of the online "marketplaces", the component count on the Apple device was IIRC twice that of the unbranded.
When this was published as it happens I was in an Apple store in the other end of the country getting a device looked at for audio issues under warranty, and the person ahead of me was complaining about their power supply failing, it turns out they had bought a counterfeit unit from an online store.
I discussed the fake part issue with the duty store manager because it just happened that he served me. I showed him the article which he read and didn't quite get the gist of it at first. With a little clarification, he understood the point of it.
He then proceeded to tell me that their policy was not to shut devices down overnight, they were left on charge at all times. Access to the wall sockets and the time taken to do this was excessive, and, they had never had fire anywhere in the world caused by one of their devices catching fire when left on charge overnight.
I suspect that many of the mobile device retailers are the same.
Genuine chare products from the device OEM must not be susceptible to overheating when used.
If they are then they are not legal for sale.
If they put the warning in their manuals that prolonged charging can overheat, then they are admitting that their devices are dangerous, and thus illegal.
It is foreseeable that such devices will be left on charge.
When I was rushed into the hospital back in November last year, my Apple watch was left on charge.
I didn't think about it, you don't when you think you are going to die.
So it was left on charge for months, literally.
It didn't set the house on fire, it has failed, it split open, but that is ongoing with Apple.
I regularly charge devices overnight, and my laptop is rarely disconnected from power.
But, I always use genuine, or reputable charge devices/power supplies, not the cheapest I can find on any online "marketplace".
I believe that the trick in preventing fires from such devices is to only use reputable and the right equipment for the job.
OK, it’s a few £ more, but in the grand scheme of things, it's nothing.
