Awesome earbuds and they work great with the Bluetooth module.

If you are looking for a balanced sound signature with musical clarity then look no further, these earbuds surpass a lot of more expensive earbuds in the balanced armature range, I recommend these earbuds and I say spend the extra money to purchase the Easy KZ optional silver core cables.

These earbuds are crazy good

These earbuds also fit very well in my ears even with their large size.

That being said, for the price, these are the best earbuds I've ever owned

I ADORE the earbuds!

I compared the ZST to the Brookstone Clear Dual-Drive Earbuds, Koss PortaPro, Sennheiser HD 580, and Grado SR225i headphones.

These are great earbuds, They sound fantastic with great high's and lows

I've played with a LOT of really bad earbuds.

n’t like was the earbuds, but those were super easy to replace

I was disappointed, the earbuds themselves were fine, but the ear loops were wonky and of cheap material, the sound was not very good, I have used 10$ earbuds that sounded better there was no deep sound to them, I considered returning them but one fell out while I was hiking a

Compared to more expensive earbuds the ES4 exceeded my expectations, easy to wear without fatigue and very clear sound

I HIGHLY recommend KZ earbuds and especially the ES4's

I always start with Whitney to test my earbuds and then break it dow to The Funkadelics before I transition to Mozart.

The earbuds are excellent, the cable is poorly made

Besides that, the earbuds are the best I've ever had.

Also I lost one of the earbuds, meaning it could be easy for someone that loses headphones/earbuds real easily and also for someone that constantly detected then because you

I have several pairs of in-ear earbuds ranging in price from $20 up to $200 and I now find that these are now my favorite earbuds.

I don't like earbuds, but saw these were cool looking figured i'd give them a shot clear sound perfect sounding for ear buds, in other words they sound amazing for the price.

I also look totally different compared to my co workers since the earbuds look super modern.

For what it is the sound quality is probably on par with slightly more expensive earbuds

Nice sound for the price but this have got to be the most uncomfortable earbuds ive ever worn

I've always either used over-ear headphones (aiwas from 20 years ago, at least) or other decent 10 dollar earbuds like JVC marshmallows or those panasonic ones which people like.

After trying a few other (more expensive) earbuds for my band’s in-ear monitor system and being disappointed, I decided to give these inexpensive ones a shot

Makes these the most comfortable earbuds ever, and for the price??

For enthusiasts and especially bass enthusiasts, I would not recommend these earbuds.

Not sure how to find better fitting rubber earbuds but they’d make a world of a difference in dealing in the great sound.

Feels durable and had a removable cable, but other than that it's hard to enjoy music with and Apple's terrible older earbuds were less offensive.

I am using these earbuds with my LG V20 phone (built in quad dac and amp) and the "PowerAmp" audio app (the best in imho).

They are earbuds, burn em in with some pink noise if ya want, I have not yet, and they are awesome

I use these as my main earbuds and I like them

I've also used them with music and the sound is like earbuds costing much more

These earbuds are amazing for the price

I think these may be the best earbuds I've ever used in my entire existence

These however sound crisp and full as I also despise tinny earbuds.-decent as a video game headset, specifically the Nintendo Switch

They're not just great replacement earbuds, they're amazing earbuds period.

These are the best earbuds I have ever had

Earbuds came as described and worked great

These earbuds sounded pretty good

By the time you get the cord upgrade and some good tips, you have spent a good $45.I have bought less expensive earbuds that sounded much better, but they just didn't last that long

I played Resident Evil for a few minutes and was delighted to hear the queitest of sounds like far away monster footsteps, I only assume this headset will be even better listening to the beautiful sound track of Super Mario Odessey.-mic seems to be of decent quality, tested in a group discord call-very comfortable while out and about, wire wraps around the back of your ear keeping the earbuds secure

, the earbuds just broke apart then eventually snapped

Excellent earbuds with microphone

Good sounding earbuds, but the structural integrity what makes me give them two stars.

Earbuds are always hit and miss at his price point and these are no different.

I decided to ditch them all and replace them with the tips off of my super cheap-o $8 Panasonic earbuds

I will recommend these to others as much as i can

I use them for in-ear monitoring in live performance, as well as with my phone and am very satisfied with the sound and with the sensitivity of the microphone.

But these absolutely blow the ATE’s out of the water

Love the KZ ZST’s
