No problem getting a deep fit, i had it varying from just the tip of the housing sticking out and tried different points along the canal till just resting on the outside. i preferred it deeper, i use the yams with extreme deep and my gr-07 just sit on the outside both working well in their variances. Stock tips were terrible so i tried a selection from my other iems listed below with varying results but still nothing overly impressive. Music was at 320 or flac through various genres acoustic guitar and some binaural tracks being the ones that were better. Tried with an ipod/e11/arrow/zo cube and clip.
Just not for me i guess but may be perfect for others.
