Review: Unbeatable value; best in its price range - I bought these KZ ES4, with the silver upgrade cable, because my last IEMs were having issues cutting out in one channel, and in short, they've blown me away. You won't find any headphones on desertcart that can beat this for £20; read on for my detailed impressions. Background: I've been interested in headphones for a number of years now, with my desktop setup being an O2 amp into HD 650s. On the IEM side, I've used various 'Chi-Fi' models for a couple of years, which is the name given to a growing category of headphones that are being released by Chinese manufacturers at sub-£30 price points with features previously exclusive to very expensive earphones, such as removable cables, dual drivers and over-ear shells. KZ are probably the most famous and widespread of these manufacturers, releasing many models that are well-known in the ChiFi community, with ever-increasing quality. My past models include the ROCK Zircons, KZ ZS3, TinAudio T2 and Uisii HM7s. Testing Method: Because IEMs are designed for portability, I tested them with my phone as the source (as I would use in normal life). My source is an LG G6, with the Quad DAC enabled and the silver upgrade cable used. For the purposes of this review, I used to following albums to base my opinions (all as FLACs): Kid A by Radiohead, Lateralus by Tool, Off the Wall by Michael Jackson, MTV Unplugged by Alice in Chains and Discovery by Daft Punk. Build Quality: It astounds me that these headphones only cost £20, including prime shipping. For that low amount, you're getting high-quality plastic ear shells (I recommend the cyan colour, it looks great!), with the seams flush and no gaps/bumps. Although I bought the silver upgrade cable, I was also impressed by the nice-looking included copper cable, which is a big improvement over the old rubbery stock KZ cable that came with my ZS3. The cables use the 2-pin socket, which I prefer over the rival MMCX connector because it feels less fragile, is easier to replace and doesn't swivel. Fit: Before I got the headphones, I was worried about the fit because I found the ZS3 to be uncomfortable. Thankfully, the fit is great with the ES4. As all the curves are very smooth and round, I find it sits flush against my ear. The included eartips are the KZ starline, which fit well and are a nice addition; I've previously bought a set separately because I like them so much, thus it's nice that they're included here. Sound quality: The important part of this review. The ES4 does not disappoint, and represents a huge leap forward from previous KZ models and other ChiFi models at this price. The sound is V-Shaped, meaning that the bass and treble are quite strong. However, unlike past headphones, the 'V' isn't very aggressive, meaning that the mids aren't overpowered. The bass is strong, with good extension and a nice 'thump' in bass-heavy tracks. It doesn't bleed into the midrange, which is important for clarity. Speaking of the mids, they are really good for a V-shaped headphones. Guitars sound powerful and clear, and vocals don't sound recessed which is important for the genres of music I enjoy. I'm also hearing a lot of details in these midrange frequencies which I haven't heard before in IEMs, such as certain background noises in 'Idioteque'. The treble, often an issue with KZ headphones, are really well done in the ES4. Unlike other cheap dual-driver headphones, the ES4 is not prone to sibilance, which allows for comfortable, longer listening sessions. The treble is still quite prominent, which allows the higher-frequency details to shine through. Overall, these headphones sound very coherent and a pleasing sound signature that will appeal to fans of a broad range of genres. They're better than all the other IEMs I've used, with the T2s on a similar level but at a higher price point. Summary: When you consider the impressive build quality, striking design, comfortable fit, removable cables, Prime shipping, desertcart customer service and most importantly, unbeatable sound quality in its price range, you're getting a brilliant little package here. Looking around on desertcart, the only other headphones at this price range are either stock headphones that come with mobiles, models from cheap, generic Chinese manufacturers or the lowest end models from big-name companies. Compared to these options. the KZ ES4 outclasses them in terms of sound and build quality, making them a no-brainer for anyone looking for an upgrade on their free headphones or an inexpensive pair to use when out and about. If you pick the mic option, they even become a good budget option for gamers looking for a decent headset that can be used for voice comms and in-game audio.
Review: The Best KZ yet - - Lets just say it from the beginning – are those perfect – well no – but those are the best KZ IEMs I tried (or own) to this day. Comfort – KZ was always quite good – and ES4 is also very comfortable – actually those are so good that I could have a power nap listening to music with them – used during walks and short runs – they stay securely in – no problems there. Look – ES4s looks solid and feels solid – shell is made of good quality plastic – I am not particularly fond of see through shell though – but that's my preferences and others may find it to the liking. Isolation – well it is average for IEMs – new shape helps a bit. For out and about it is just perfect as it helps yo stay connected to surroundings – but for loud public transport it might be not enough. ES4 came with standard Silver-plated 99.9% pure copper cable – no thrills – does its job but suffers a bit from microphonic effect and I was never a big fan of those cables so this time I decided to opt for upgraded cable – I picked up Yinyoo 6 Cores Copper-Plated Upgrade Earphone Cable – and I am very very pleased. Cable looks good – it actually looks more premium than the price tag would suggest, and to be hones it looks way above ES4 class – and is cheap (bonus in everyones book I am sure). It is also soft – very soft. It is 3 or 4 times thicker than standard cable but is much softer and NO microphonic effect at all. One downside of this cable – no markings at all – left, right or polarity – you just have to work it out yourself. And the most important part – Sound - ES4 is a hybrid construction – using 10mm graphene dynamic driver for the bass and midrange, and a balanced armature for the treble. As they say less is sometimes more – sound signature is a bit V shaped – enough to make it fun – with good rumbling low end and just enough sparkle in top regions, and not enough to makes vocals pushed away. The way ES4 reproduce vocals is what make me say those are the best KZ IEMs to days – older single driver constructions had the low end and sometimes even a nice top end but were not so great in the middle – multi driver ones like ZS5 – were a bit overdone and with piercing top, and still muddy middle. Over all ES4 are well balanced and smooth (sporadically a bit hot though but nothing like ZS5!) very enjoyable and musical – for the price – easy to recommend. If budget can be starched a bit Yinyoo 6 Cores cable is a must have upgrade.

### ⭐⭐⭐⭐ Excellent sound quality, but slightly bulky and easy to lose
*by B***N on 18 January 2019*

After a month of daily use I really really like the sound of these - excellent quality across the entire spectrum, with nice non-fatiguing definition in the highs, great power in the mids, and strong and precise bass. Can't really ask for more for such a price. They fit comfortably in the ear, isolating background noise effectively, and eventually I forget that I'm wearing them, however, I find them just a bit bulky to carry around. Definitely not for sleeping. Also, you have to be very very careful to not lose the buds, especially when putting them away - the cable detaches very easily, and on a number of occasions I was almost ready to say goodbye to them after one or both buds fell on the floor in the restaurant/on public transport/in the park... Very luckily, I was able to find them at the last minute, so now I'm taking care of them like gold. Great buy, but take good care
