By the way, the bass is not overpowering at all: it's just natural.

Also a good seal is required to get good bass otherwise a little bright

Thin sound with weak bass

Great bass response, They do alter EQ a bit

The bass is adequate without the risk of most people identifying you as a bass head a-la Beats products.

Good bass

It is very nicely balanced with good clean bass, smooth midrange, and satisfyingly bright highs (without being harsh at all)

For the price, I've yet to hear anything else with nice balanced bass and treble response

the left and right earphone did no it easy I really hate that moment, because is not fast and easy, about the sound quality es poor no good bass and the treble es equal poor

Great clear highs and full bass

Some IEM's have the bass, but lack clarity

For sound, I listened to these first - just a single pop/hip-hop tune - good bass/drums and vocals

Excellent sound quality, good bass response and super cool custom look!

This means he/she will mostly hear frequencies ranging from 100hz to 20,000hz (everything below 80hz will seem vaguely absent) and then he/she will complain that the ZST doesn't have enough bass

Great product love the bass in them

"Under My Skin" (test clean bass, vocal presentation

In this case the dual driver alignment is an excellent configuration, maintaining the very strong, sometimes astounding, deep and authoritative bass these units are known for but also improving the refinement of the mids and upper highs

Bass is also very well balanced, clean and crisp not overwhelming because when its overpowering then things gets mudded

What kz es4 does is provide precise bass response while making music sound fun

It has almost tight enough mid-bass without an overwhelming sub-bass (I'm a tight mid-bass snob, so that is actually a compliment).

Bass is conservative but well extended

I personally love bass in my music, but I'll get to that later.4

The sounds signature is very balanced, coherent top to bottom with good deep solid bass, very clear mid range and beautiful high frequencies with no harshness.

Bass is great

Bass can be heard good (not super) and the highs are clear

There is a pretty well pronounced mid-bass hump that isn't detrimental to the sound

Bass can be heard good (not super) and the highs are clear

With its powerful bass, kz es4 is also able to create a sense of depth to listeners

Sound is crystal clear, and has excellent bass sound for the money (I play bass)

Which brings me to my two negatives: The bass on these is still only just enough and the ATEs come with great foam tips which are NOT included with ZSTs and in fact, don't fit properly them either.

It has almost tight enough mid-bass without an overwhelming sub-bass (I'm a tight mid-bass snob, so that is actually a compliment).

Strong bass, crisp high frequencies.

" (test handling complex bass & drums)Otello - "Masterworks Collection: Las Vegas" (test handling complex bass & drums)Otello - "Masterworks Collection

Without a good fit I could not get that rich deep bass sound.

Sound: clear energetic bass and sub-bass , normal mids and emphasized detailed highs

Good sound quality, deep bass, sparkling highs, subdue mids

I'm a drummer and I need everything from decent bass to solid bass drum sound coming through my ears

For me, if they are just slightly off you lose bass.

I prefer my headphones with good, clear, punchy bass and good highs that aren't too brassy.

the left and right earphone did no it easy I really hate that moment, because is not fast and easy, about the sound quality es poor no good bass and the treble es equal poor

Downtime" (test clean bass & vocal presentation)Antonio Vivaldi - "L'Estro Armonico" Violin Concerti (test for shouty mids/violins)Sound Signature:1

Incredible bass, vocals are clear and articulate, highs have great sparkle and a sense of air, and they have great isolation.

In this case, I ultimately ended up with the small tips that were most comfortable to me at a slight loss of a better seal and bass performance as a trade-off for longer wearing time

These headphones are absolutely fantastic, the bass is very good and the lows are wonderful too

With a twinge of guilt, I activated the vulgar bass boost on my Fiio A5, then let the tunes fly.

Treble lacked clarity, but they had decent bass if the range didn't need to be extended in the song

Great bass and noise insolation.. better than others more expensive..

Most people enjoy the bass on the Sony MDR XB50ap

KZ tuned these so the beautiful bass doesn't bleed into any other frequencies

For some reason I thought these where bluetooth but great bass.

Nice tight bass, smooth (not dull) mids, and clear highs

I am a singer, so having the bass line clear in your ear is key

but I'm near to it as I despise overblown bass and used a gifted pair of beats for

Unfortunately i cant wear air-tight earbuds without feeling dizzy so i loose some bass.

The bass is extremely solid and not overbearing.

Get them fitted properly and sealed in your ear canal, and you will have full, rich bass and mids.

I am a huge electronic listener, and bass is critical to the genre

balanced and natural sound, bass was slightly recessed and a bit more analytical with the stock cable but with the upgraded cable the bass is boosted nicely

Terrible bass

Very strong bass

No bass, sounds plastic and all around bad for any style of music

Good bass, silence the noise around you, thus giving you world of your own

Good bass, silence the noise around you, thus giving you world of your own

Highs and mids are crystal clear and the bass these things can produce is insane!

If the earpiece isn't fully set in your ear, bass is almost nonexistent: not this earphones fault, happens with every earbud but these tens to work their way outConnector issues: connector is too big to fit into my phone caseWhen plugging directly into my phone the connector sometimes gets staticky and one side will stop getting signal if the connector is spun a certain way

They even enough punch for most bass heads to enjoy

AWESOME the bass and the quality itself is better than my AKG's!!!

This was probably the biggest surprise for me given how authoritative the bass is delivered in modern genres

I don't recommend as highly for listening to music as they lack bass

I sort of just thought because everybody's ear canal shape is slightly different, you would just have to put up with varying degrees of uncontrolled bass.

In-Ear buds (like MDREX15LP) for years now for the great bass response below 20Hz

Sound: great sound, good bass, pretty well controlled, good without being whistling and well rounded, for the price that has a very good product

Bass is very responsive

The bass is a little underwhelming however everything works perfectly.

Great bass and noise insolation.. better than others more expensive..

Using my modded iPod Mini with a Fiio E07K gives me crystal clear highs, smooth mids, and all the deep, clear bass you could want.

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.

Love the KZ ZST’s

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