HiFiGo DUNU S&S Earbud Tips for 4.0mm-6mm Nozzle, Silicone Ear Tips Replacement for Da Vinci, Explorer, Titan S2, Wireless/Wired Earphones (S(3 Pairs))

Would never cross my mind that this tips are the best tips for fit and isolation for any iem . And I have 140 different types. Well done dunu

They stay on the buds and in my ears.

You might not think it given the shape, looks pretty basic, right? and the way it's not tapered like most tips, that must ruin fit, right? Wrong. Right now this is the sleeper tip to get, it's truly up there with Springtips and Spinfit W1. Sound wise it is a very "clear" tip, there is a sound signature to them but there are no big dips or peaks, rather they sound very natural, like Sprintips but with more air and bass retained. I love Springtips but they can sometimes let out enough bass and smooth the upper highs to make them not ideal on the wrong IEMs. Step in Dunu S&S: The bass comes back to a more neutral level and all the highs are brought back forwards in the presentation (for good or bad). The reason these tips sound good is the same as the other top tips: the end of the tip forms a wave-guide in your ear canal that stock tips fail to do. In the case of the Dunu, the stubby end combined with the very soft silicone allow the tip to roll back slightly when it place, forming this shape. This is different to say Springtips or Spinfits where that wave-guide shape is formed withing the bore of the tip. From the outside the Dunu looks like it has a conventional straight hard bore like on stock tips but I'm telling you it's different in the ear. Fit wise the shape of the Dunu S&S allows it to "jam" in place very well in the outer ear canal while remaining comfortable. You might think that a more conventional tip end that goes deeper would have a more secure fit, but the Dunu proves this is often wrong, with the one caveat that it might not fit into the smallest ear canals that might have a weird angle, for that I would still try Spinfits first. The bottom line is these are cheaper than Spinfit W1 (considered by many to be the best tip), you get more in each package, and they sound and fit just as good to my ears. If the W1 is better it's only by a hair, so this is a no-brainer for tip rollers and those with many IEMs.

Los mejores ear tips a mi gusto, sellan bien el sonido, son cómodos y no resbalan

impressively comfortable. bought another pack of the right size, right after this purchase

Excellent! Hold well in ears and smaller sizes fit deeper so more are useable.
