Ok now ive got around 15 hours of pure pink white brown noise and some frequency sweeps for the bass. Let me tell you that the mk2 versions are the best dual driver armatures i have ever heard. The bass is slighted more boosted than the previous dba02/b2 but retains all the amazing clarity and smoothness.The transparency and balance between bass mids and highs are just freakin amazing. Paired with my nano 6g > AW audio gold dragon lod > fiio e11 playing back to you by john mayer converted from flac to mp3. I just cant get over the clarity and details this little baby produces. Its like floating in the sky and just drifting away. None of my gears come close to this kind of clarity. Not even the z1000,L1,dt1350,es88,ckm77,UM merlin, westone 4, etc. I salute FA for a job well done. My search for a super detailed but smooth and non fatiguing dual armature iem is over. And btw im using shure olives as my tip because its so comfortable
