I had bought the ZSN Pro X's from KZ and I love them. I had originally lost my old set of Sony earbuds on a vacation trip and had never managed to find them. I had gone a few months with some AKG earbuds - the ones that often come with Samsung phones - and it was kind of terrible. I had one of the earbuds burn out on me, I believe it was the right one, and I was left with listening to all of my songs with music coming out of just one of the two sides. Eventually though, the right earbud ended up breaking as well, so I downgraded even lower to some Puma earbuds. Let me tell you, I absolutely hated those things. First, some of the wiring must have been loose or bent or something, because most of the time the Puma's would sound tin like and would lose the higher frequencies, more specifically the ones that the human voice projects, so most of the time the music or video or whatever I had them plugged in for would not even be audible. It could be fixed by repeatedly turning the aux connector around to get to some sort of sweet spot, however that sweet spot would always change, which would mean that any time I would want to use those stupid earbuds, I had to turn them around like I was screwing a screw in to the aux port in my phone for like a minute just to hear people talking. Second, one of the earbuds was much louder than the other one, so much so that the quieter one might as well have been burnt out. So not only did I have to fiddle around with the connector every time I used them, but I also had only one of them to use. Needless to say, I definitely needed a new pair of earbuds. So one day I was watching this YouTuber that posts videos about Ipods, old music players, earbuds and headphones, and other audiophile stuff. His channel name is "DankPods" and I highly suggest that anyone, audiophile or not, check him out. He had a video on Christmas gifts for audiophiles, and one of the items that he recommended was the KZ ES4 earbuds. I did some looking for these earbuds and I eventually stumbled onto the Linsoul website where KZ sells all their stuff. So after some time of looking around at their products, as well as some other stuff on Linsoul that is astronomically out of my price range, I settled on the ZSN Pro X's. And they are perfect! Finally being able to listen to something with both ears without using my phone's speaker was an absolute godsend. And the fact that they mute a lot of outside noise without any use of noise-canceling technology is really impressive. Even though I prefer wired earbuds to Bluetooth for multiple reasons, the fact that I can use the same buds with a Bluetooth cable is an excellent design decision. The construction quality is superb, and I love that the wiring is silver. The silver wires really amplify the appearance too, giving the earbuds a real luxury look. Even though there are only two drivers, they really sound amazing. I don't think I've ever been able to both hear and feel the bass and sub-bass of music before. And all of this for under $30! The only legitimate criticism that I could give about them is that the normal shipping from the website really does take forever. It took almost a whole month to finally get them, but I really got to say that it was well worth the wait. I was originally thinking of getting the AS10's to replace these, but I think that even if I did I would still keep the Pro X's around as a backup or for travel. I absolutely love these earbuds, and I cannot recommend them enough, especially for the price that they are. My only suggestion: get express shipping, it'll be worth it.
