Etymotic ER4XR for 320 €
Sennheiser IE 300 for 220 €
Of the ER4XRs I am a bit scared by the very deep insertion, while IE 300 are described by the owners as among the most comfortable IEMs ever.
Hifiman Ananda are overall my favorite of the headphones I've had. But I love the Sennheiser HD 600 more for vocals.
