erjigo in-Ear Monitors, KZ ZSX 1DD+5BA Hybrid HiFi Stereo Noise Isolating Sport IEM Earphones/Earbuds/Headphones with Detachable Cable for iPhone, iPad, Android, Computer (Without MIC, Cyan)

Absolutely amazing! I'm amazed at the sound quality it's like bringing my dac, amp and speakers with me wherever I go. The quality and sound is out of this world especially for $50, and not to mention this is from my cheap phone with no external dac or amp yet and they're very easy to drive and get very loud and clear/clean highs and mids with tight deep bass! What more could you want.

I got these to use as monitors for my DJ controller. They work as advertised for that; I'm not looking for great clarity - just something that fits in my ear and plugs into the controllerI have wireless headphones and nice speakers for gaming, but thought I'd try these out... Holy crap! COD MW sounds GREAT! Compared to my Arctis (both wired and wireless version) these KZ ZSX's provide a great depth of sound audible dimension. They're ok at preventing outside sounds, but I can still low tones from the TV in the other room with my office door shut and not playing anything.I just felt I needed to edit my post and re-iterate this. If you're into FPS, and looking for "radar" to know if someone's around you, these do the trick. I'm playing games where no one gets the jump on me... You hear their footsteps, and where they're coming from a mile away! *secret weapon*The fit is comfortable around the ears. If I had to ask for improvement, though the cord is a standard length, I wish it was a little longer so I could fit it under my shirt when plugged into the DJ controller, and have some more room to move around.As an IEM for a DJ controller - I'm a total amateur, but it's really nice not having bulky over the ear headphones to put on and off all the time.Worth the money!

I'm reviewing the with-mic option (some ppl say the mic cord degrades sound quality, but boy is it good anyway). I'm using separately-sold memory foam eartips, which seem to help with a fuller bass sound.I'm not an audiophile or musician. Just like my music to not sound tinny or overpowered by bass. These are my 1st IEMs. I'm going to compare to Galaxy Buds plus (true wireless buds, costing over $100) and Sony MDVR6 (over-ear studio monitors, costing $80+). Sound-wise I like these KZs the best, although the Sony's come very close: I'd say for me the Sonys and KZs are "different" not one better than the other. The Buds plus in comparison are all bass, everything else both muddy and tinny at the same time.* Mic quality: haven't tested on a phone call or with a lot of background noise yet, but I need to hold the mic up close to the mic when speaking into a voice recorder app. When I do so, it's as clear as the phone's speakerphone mode, and picks up less ambient as well. Probably ok for occasional on-the-go phone calls, but not for working from home.* Difference to earbuds:Sound quality of these IEMs is GREAT at a very cheap price. But all the IEMs do is play sound and/or have a mic. Earbuds these days control your smartphone: volume, skip song, pause, read notifications aloud, etc. Also the Galaxy buds plus have a pass-through mode that lets you talk on the phone and hear your own voice quite well. So if you want those features you will want earbuds. If you want really good sound for a cheap price, go with IEMs.Cons (not faults of the product, but cons vs wireless buds):* These are wired. The Sony over-ear headphones I'm comparing to are also wired, but they have a nice coiled stretchy cable that give some freedom of movement. The KZs are meant to be plugged into a device in your pocket or strapped to you, not a tablet or pc. Move around too much with these and your table-top device is going to get dragged (or the monitors will be yanked from your ears).Conclusion:Hard to say. If I get the bluetooth adapter for these IEMs the combined price starts getting close to the price of true-wireless earbuds and earbuds can also control your phone. So for on the go, it's a toss-up whether in 2021 one can deal with a wire running from your pocket to your ear and no ability to change volume or song without getting your phone out. For at home, or at desk music listening these seem at least as good as good over the ear headphones, and have much better sound quality to wireless earbuds in the $100+ range.Compared to over-ears:I can dance and shake my head with these more than I can with over-the-ears. These don't come out. I can probably run with these, but wouldn't want to lift weights etc with a cord that can get snagged.

These do not fit well and hard to keep in ear. My much cheaper earphones sound much better and much more bass. The treble is very high frequency but that is all you hear with this. Buy name brand and they would have more honest advertisement and better quality. I didn't expect to good bass for in ear earphones but this has non whatsoever and the high frequency could ruin your hearing. Maybe after few hundred hours it will sound better so will let you know. In the mean time pay a little more but get name brand.

I had previously purchased a much cheaper model of these and when I finally made the upgrade to this higher quality version, I only wondered why I waited so long. These have superior fit, clear sound quality, and the durability of the materials is obvious. No more trouble with the earpieces coming disconnected from the cords, and they don’t repeatedly fall out of my ears. I would say this is the best I can get without spending hundreds of dollars on custom-molded in-ears.
