"not only "perfect fit", but also "perfect listening""5.0 starson by UPae
Pros: - the cristal clear sound
- the incredible precision in all frequency ranges
- the feel of it (effectively, once put, you don't feel them at all)
Cons: Nothing at all, after 6 weeks' use
Summary: Instead of reading reviews, you should simply try them in order to experience the pleasure of using them.
Having listened (via nano 4th generation) to a wide variety of my favourite music (rock, R&B, various periods of jazz, classic music from various centuries and composers), I am amazed. Everything comes out in a perfectly precise manner, no over- or under-accentuation of any frequency range. Just as it should be!
For me, the (foam) sound isolation works efficiently, both in aircrafts and trains. It blocks the general noise, but leaves me aware of the fact that there are cabin announcements, so that I can pull the earphones out, in order to understand the messages. Absolutely total isolation might be difficult to achieve, perhaps with the silicone tips which I have not tried.
