Greater than one weekFirst, I will preface my review by saying this is my first experience with IEMS that have multiple balanced armature drivers. My only other experience has been with sub $200 dynamic driver IEMS. For the price what you get is hard to beat. I have no complaints with the build quality, and even with their large size, they fit comfortably in my ears. However, the included silicon ear tips do have a tendency to slowly slip out of my ears. This can be remedied by any of the available third party foam ear tips. Sound quality is good. The level of detail these drivers put out is impressive for the price, while the soundstage is simply average (You can definitely tell the sound is being piped into your ears). I cant call the sound signature neutral, although I think it tries to be. It is a little warm and the treble rolls off a little too quickly for my taste. Bass: Anything lower than 35hz disappears while everything lower 60hz is a tad quiet, but the quality is still good. Still, I find I can get adequate rumble and thump from the low driver while maintaining layer separation except when in cases with many heavy bass layers. The low-mids are a bit warm, which is fine if that is something you enjoy. Mids: I dont have much to say about the mids except that the slightly warm boost in the tuning of the drivers can cover up a little detail here. Otherwise I am pleased. Treble: While after about 14khz everything rolls off sharply, the treble that is produced is detailed and clear. I found my pair of KZs had some spikes in frequency response around 8-9khz and 11khz, which could just be the result of the shape of my ear canal. Whatever the cause, the result is that these earphones come close to being neutral, but there appears to be some areas where the tuning could still be improved. Now, I do not only want to pick apart at the sound signature. These are pleasant headphones to listen to with a nice slightly warm sound signature and a higher level of detail than what most will expect from this price range. In fact, the main reason I bring up my observations about what is lacking in driver tuning is because I think a lot of them can be helped with a little eq. Now, if you have a listening set up wear you can use a frequency analyzer and a PEQ you could really dial these KZs in, but personally for my casual listening experience I can solve about 90 percent of my complaints on the regular GEQ that comes on most smartphones by by boosting the sub-lows about 3db (around 60hz), cutting the low-mids (between 200-300hz) a few db, and giving a slight boost to 16khz (just my personal preference). Even without an eq, I am impressed with these IEMs and prefer them over the pair of Yamaha EPH-100s I bought years ago for twice the price.

> 3 dayThese sound nice but the ZS10 was better for me and ZSX is the best Ive heard due to excellent frequency separation and great natural highs.

> 3 dayI am really impressed by how I can actually hear all the frequencies, I have a pair of closed back over the ear AKG headphones that are $200 that these have a comparable frequency response. I haven’t had the chance to use them on stage, but I am expecting these to work better than the Shure IEMs that I used until the cable wore out. These have replaceable cables so that will never be a big issue

> 3 dayThese sound great! Ive used these for over a year and theyre still working fine. The only issue Ive had is a slight buzzing/white noise sound when there is no other sound. Especially when using these on a windows desktop it becomes more apparent.
