nice review. could you compare this to titan 1 and oneplus icons?? thanks.

@AsheshM, Unfortunately I have not owned or tested the Titan 1 or OnePlus Icons to compare.  Hopefully someone else can post with their experiences.  

**Disclaimer - I was provided the EX1 from FiiO in return for an honest review**
 
Can you clarify that? Is it a loaner or a freebie?

@taffy2207, I retain the EX1 after the review is finished.  

I have these as well and love them. Very comfortable and easy to listen to for long periods. When I am out and about, these are my go-to phones because I can still hear what's going on around me and they are easy to insert and remove. Great review mate. Cheers.

I personally don't like how Fiio messes around with Dunu's products and releases them as their own. And even then Dunu does a better job by themselves xD You should really take a look at the Titan 1 if you get a chance, definitely no harsh highs or recessed mids there.

@avitron142, FiiO is open about the fact that their earphone is a Dunu, thus why it even says it still on earphones.  I am sure Dunu and FiiO worked together to give the EX1 a slightly distinctive sound to differentiate it from the Titan 1.  It is up to the buyer to find what signature they are drawn towards.
