Cosmos4 Pairs Removable Soft Silicone Earphone Hook Holder Sports Ear Hook Earphone Wire Cable Hanger Earclip for Sports Earphone Headset

Ok to use.

They won't work for audio monitors. Not sure how they messed this up but it's not even close to fitting.

I would have loved to give them 4 stars for doing a pretty good job, but the skin behind my ears says that they rate 1 star because the mold seam gets more and more aggressive the longer you wear them. I'm going to take something real sharp and see how many I accidentally mess up while trying to slice it off. I'm probably also going to slightly shorten the forward overhang so that maybe my left ear can have enough slack to stay fully inserted. If the seam area is still a problem after modification I'm going to downgrade this rating and go hunt for something else.

Added these on to my Tripowin Zonie cord, and this takes the cable from being loose and rubbing against the back of my ear, to a snug, comfortable fit that doesn't move. No complaints on comfort, at least not right away. They do seem a bit cheaply made, with obvious flashing on the seam of the silicone, but it tears off easily enough, and all in all they're good for the price. Oh, and while the description says the colors are black and "frosted clear", the ones that are supposed to be clear are solid, opaque white in the package I received. I don't mind, I'm going to use the black ones anyway, but worth noting if you were particularly set on them being clear.

If you pick up any KZ earbuds, you've likely watched dankpod's review about it. Essentially for the price point, its really hard to do better and with more price you get diminishing returns on quality of audio or experience using it. This is one of those products that make earbuds distinctly more comfortable.

So, these don't actually fit the KZ ZSTs really, they don't fully wrap around the cable; causing them to fall off very easy. I had to use shrink tube to keep them on the cable. Other than that they do help with the comfort I guess.

As a universal fit, it is almost guaranteed they won't look pretty or neat for your earphones. But, I am surprised these turn out to be much better than IEM style over the ear all in one cables with hooks built to the ends. It's probably not by design, rather a coincidence.The reason is exactly why they don't look pretty. The hooks can only cover the cables, leaving the earbuds hanging so that there is a bit of wiggle room between the earbud and the hook. That small amount of wiggle room makes the earbuds more stable in ear canals, because it releases the tension from the hooks and the buds won't move immediately along with the hooks. As a result, the earbuds can better stay inside. Compared with most IEM cables where the hooks are mostly slippery plastic, these silicone hooks are wider and kind of a little bit sticky so they also stay behind ears more firmly.These small differences actually make wearing earbuds much easier and I find myself don't need to adjust as often as before. I know it's not true, somehow I found the sound become more pleasant.In the picture is a pair of Sony XBA-N1 with a 16 core cable. The cable is obviously too wide and I used some thin fishing string to tie it up. Not pretty but works perfect.

Honestly, these are horrible. They don’t even stay on an acoustic tube without being taped.
