Pros: level of details, vocals, soundstage
Cons: poor treble, need burn in for at least 50 hours , muddy with bad recordings
These iems are better than some entry levels (Shure 215/ hifiman RE0/ RE 400/ Sennheiser CX300) with a wider soundstage due to the 13mm dynamic driver , however need serious burn in for at least 50 hours to shine , lack sub bass and treble , perfect with vocals (Norah Jones / Yael Naim/ Celine Dion), not so convincing with classical music even at 24/96, bass not punchy enough for electronic /dub but should be fine with reggae, pop and alternative genres.
Can be worn over the ears with this combination : ( R over left ear , L over right ear ) , good isolation , should avoid lossy and bad recordings
Gears used for review: Iriver Lplayer , Samsung Galaxy Note 2 (Neutron, Poweramp), HP Envy , Sony Walkman D-EJ100, iphone 5s, Astell & Kern AK100
