Usually, I listen to music with my ears

I belong to the dying species, who's buying CDs. But I don't listen to them

They become ripped as MP3 and migrate to my external HDD, which is connected to my Yamaha-Receiver. And I can simply copy them on my 64GB MicroSD-Card in my smartphone. From there, I listen to them with my Magnat Headphones (I think, I posted a picture of them in the Last Purchases thread).
I want to buy a Bluetooth-speaker for my phone, but I had some problems (which I will talk about in Campion's Computer Corner later).
