the sound will be improved if u used the tips with deep opening or wider tips

I have two samples, one with more bass and other with less. I like the one with more bass. I think these sound better than the MH755. Sounds more spacious and more even (based on stock, no mods).

I have compared them to MH755.. They are both on similar level except the MH755 has a less forward sound signature and a deeper sound stage and more crisp around the treble edges . the Samsung AKG has a wider sound stage more forward sound.in terms of separation layeing they are almost similar.

@SweetEars I just tried it with different kinds of wide-bore tips. I posted my findings inside a spoiler at the bottom of the review. I didn't notice a significant difference from stock tips. This IEM is sensitive to insertion depth. If you're getting much different sound, could it be that your wide bore tip facilitates deeper insertion or makes the effective distance to the eardrum different? It could be that, if we haven't ruled it out, instead of the difference in bore diameter.

I used the orange lining tips and wide bore black tips... both sound good with wider sound stage and layering..
