fuck you Google

You can thank Apple for pioneering that one.

Belkin makes a dongle like that, I've not had a chance to test it, but Amazon has reviews if you want to roll the dice for $10 + $5 Shipping

Here's one that I have that works great. Others are cheaper though.

The belkin ones are pretty reliable for me. They're also cheap enough that I haven't minded handing them over to family and friends as needed.

Edit: they also make a splitter so you can charge while using a usb DAC, and it works well too. If you were thinking about that kind of thing in the future

I have one of those, it’s a small adapter, and it adds ground loop noises / buzzing when charging… probably because they are made cheaply without proper isolation from the switching power supply.

They used to make docks for iPods that would do both, I would look for that style.

For some reason I can't edit my earlier post. The seller w/ that price is not Amazon...so a big YMMV. Here's one from Amazon for $30, so if you want to return it it should be less of a hassle
