I'm wondering if getting a portable amp would enhance the sound of the earphones. Currently have UE900. Looking for high quality and small. How do they connect? Currently I'm just plugging into my iphone 5c.
What pieces do I need to make it work? Thanks

Suggest that you poke around the Portable Amp section of the Equipment Forums.

You can buy a mini to mini interconnector to connect them
