What are nice tips from AliExpress that I should buy for my ZS5? What diameter are the ZS5?

I'm so happy with my first portable rig!!   I've bought a Clip+ with a Fiio E11 and the Shure SE215. The sound is so nice. When i play CCR the bass is excellent. I will use this combo for my work at a cheese factory. So i'm looking for a bag with a clip. So i can clip the amp on my pants...

  This one. 90 euro.

i ca buy a set of ultimate ears triple fi10 second handed for $120. Should i do it or should go for a new pais of Shure SE215.   are there thinks looking out for before i buy second hand headphones?

I want to make my own wire for de Shure SE215 but i can't find the connectors to my headphones in europe. So my question: where can i buy the connector and the wire in europe?

I just bought a Audio-Technica A500 for 30  euro (about $35). It was a demo model for coolbleu.nl  I will use this with a Clip+ and Fiio e11. Is this a nice deal? First i was looking for a Sennheiser 201 am i better of now?    

I'm looking for a good headphone for my work in a cheese factory. I have a Sansa Clip+ and will to buy a Fiio E11 with that.  But my Sennheiser hd 228 is broken close to the mini jack and let pass to much background. My budget is $60 what is the best choice??
