ive A/B'd the earportz and the westone Star tips.
1. materials: both ear portz and the ''star tips'' are made of medical grade silicone both are very soft. but in comparison to softness between the 2 i feel the silicone of the earportz are softer.
2.design: the design of the ''star tips'' really seem to mimic the comply tips. however imo the star tips have a much more narrow opening. when you insert the tip into your ear it doesnt conform to the natural shape of your ear canal, this can feel intruding with the star tips. also can make for a decent ammount of pressure to ''isolate''. The design on the earportz rival the star tips in many ways. one its a soft soft triple flange design, also designed to mimic the natural shape of your ear canal. this along with the triple flange design creates a very natural but isolating expierence. there isnt any of that pressure you get with the stars to achieve isolation. like ive said before, with the earportz when you get them right you get not only exceptional islation but it also feels natural which is very nice.
3. NOW what matters to me most. Sound: i really really wanted to like the westone star tips however becuase the design does mimic the comply but without the pliable material of the comply. when comparing the earportz to the star tips in this matter. the earportz once again won me over. the narrow opening of the star tips seems to effect the mids and esp the highs it seems to veil both mids and highs which imo the w4r doesnt need. on the other hand the design of the earportz tip works in conjunction to create not only exceptional isolation but also exceptional sound. the earportz have a tappered bore on the inside, which mean it goes from smaller to larger at the very tip of the tip. this gives it a horn type effect. so even though the earportz are seated inside you ear canal, they still dilver deep impactful bass. but also the mids and highs arent sacraficed. crisp clean clarity from the earportz.
i dont want to sound biased to the earportz, just doing a a and b comparison of the star and earportz earportz win in every aspect imo. i really wanted to like the westone star tips as i like the visual asthetics but i really feel i wasted 25.00 buying the star tips in my opinion the star silicone have no real significant sound improvement. the star tips are not better than what you used to get with the w4r the clear tips/e2c design tips.
i had every intention on getting the custom westone tips but since these earportz works so well for me, i think i will pass. plus ive heard that the um56 tips have a tendency to make the soundstage sound smaller, and fit issues could become a issue.
