I have received my pair from
Advancedmp3players.co.uk and OOTB they sound amazing. I don't have any other IEM close to them to compare but I'm already satisfied.
Playing a bit with the tips I feel that the wider bore stock tips give me best sound and fit, I need to play a bit more.
There is some slight grain when a song is too much detailed and needs better instruments separation but we are still at 5hrs burn in.
Also when they are connected to my HTC M9 using PowerAmp there is a slight hissing at the silent parts of the songs (using 320kbps). Is this due to the sensitivity of the IEMS, the quality of the MP3 or the source? I need to figure it out
On a side note, my pair was a clearance (open box) item and I must say that the service by
Advancedmp3players.co.uk was stellar and they are now high on my list for future purchases.
