I would like to share my last 2 weeks experience with JiangHai DT86. My pair was already in transit when I’ve read negative comments in previous thread, so I was little bit disappointed. I was even more disappointed when they arrived and I’ve heard them for first time (connected to Cowon Plenue D). They sounded anything but nice. Without any big hopes I’ve decided to do some burn in, so I let play daily various music for couple of hours and usually every second day I’ve quickly checked if there are any changes. In past I’ve heard that burn in could help, but this is different they’re now like changed IEM’s. Sound is much more open, harsh in middle disappear, they’ve got nice little warm/natural tone. To my ears they’re quite balanced with good amount of details, but not boring and I’m really enjoying music. Vocals (male/female), guitars (electric/acoustic), piano, violin.... – it all sound so natural.
Very very happy with them.
