Every smartphone platform has media player apps available that can play locally stored media files. Seems a better idea to me to use the device already there just in a different way.

There’s also plenty of great media player hardware on the used market if people really must have a dedicated device for this.

I just hope the shockwave doesn’t knock down the rest of the economy with it.

BPAs have been shown to absorbed through the skin. Headphones are increasingly worn for long, continuous periods. Unlike other plastic objects which are handled for shorter periods.

I’m not entirely convinced of the danger myself (tinnitus seems a bigger worry for headphone use to me), but I thought it was a matter worthy of further discussion.
