The only problem is comfort, they are struggling to fit in the ear, even trying one by one the 6 bits provided.
The problem is that for this kind of listener, bass just depend on the insertion position.
2nd flat, there is only one control on the cable: hang up / pick up, we would have liked to play a song and adjust the volume!
That said, I shall give a layer, I discovered a new world in terms of quality of listening. I had never heard a sound as good to-ear. Acute balanced, clear midrange, and low round lovely well (when the nozzle is inserted).
