This thread is for the Samsung Galaxy S4 I9500 (Exynos version with Wolfson). A separate thread makes sense since the I9500 performs very different to the I9505.
My impression including some issues are as follows:
- Volume is very soft
- lack of low end on most headphones
- sounds good once connected to a headphone amp
- most irritatingly I have some crackling issues between tracks after 10 minutes or play when using my FiiO E11. There is no crackling when powering the headphones directly
