Anyway the first thing that strikes me is the distortion at higher volumes, im not one to use extremely high volume but i sure do like to tests earphones out and i expect a quad armature set of headphones to be handling high volume with ease but the music turns to **** at high volume its really shocking, besides this issue i am having no problems at all with the iems the sound is good, lack of sub bass is noticeable but isnt an issue and mids and highs perform admirably.
I am simply using an iphone 5s and fiio e5 to boost volume. Have tones down my headphone collection massively since having kids and getting married but the sony ex1000 were starting to show signs of wear with paint chipping and cables that seem to be non existent in the real world so cant be replaced. Hence they were sold and i got these.
But this distortion guys, is it just me? I like to know the headphones are capable at any volume but just knowing they lose control when played loud is frustrating.
The UE900 is a 30 ohm load and the Fiio e5 is rated at 100mW into a 32 ohm load (and .009% distortion at just 10mW). Distortion will likely rise exponentially as power increases.
If you're diming the output, it's very likely at least some of the distortion you're hearing is from the amp.
