优点 - 清晰可靠的调音，优质的低音效果。 价格闻所未闻的闻所未闻。 实际上可能比你更昂贵的耳机听起来更好。 良好的成像和细节。
缺点 - 缺乏深度和丰满。 你可以获得10美元的配件价值。
我从NiceHCK转发了D4的审查样本以供审查。 这些可以在这里购买。 谢谢Jim支持社区，更重要的是支持这个爱好。
已经有一段时间我潜入了廉价的预算水域，但偶尔出现一些东西，只是重新排列你对超级预算chi fi领域可以实现的想法。 我对许多原始设备制造商现在提出的东西并不陌生，但是拥有许多所谓的爆炸声，对于10美元的IEM声音有什么限制？
所以Jim @ NiceHCK建议我听到EZAudio D4。 他说，听起来真的很棒。 你是对的。 $ 10 IEM听起来真的很棒。 我以前在哪里听过这个。 嘿，我愿意给他们一个好听的。 如果听起来不错，为什么不呢？
据我所知，EZAudio D4是唯一一款名为EZAudio的产品。 可能是来自中国的随机OEM的一系列便宜货币。 该设计模仿了headfi社区应该认识到的设计。 这些看起来和使用相同的材料，但老人，但好。 NuForce NE700m。 但这就是相似之处的结束。 这些调整方式不同，实际上我认为是对旧NE700m更多彩色调音的实际升级。

D4采用了一种久经考验的真实设计，被称为10mm Titanizing驱动器裸耳式耳机。我确信他们的意思是钛涂层隔膜。这将为您提供有关您在这里的内容的线索。传统的钛涂层动态耳机具有出色的清晰度和低音。 D4并没有从这些方面发生太大变化，但价格却无法正确调整。对？
他们的SQ的第一个暗示将是他们正在使用的驱动程序。钛涂层驱动器并不常见，特别是对于预算fi产品。在Dunu Titan 1和类似NuForce耳机的耳机上更常见的是同样的形状。
D4的声音最好被描述为平衡调音，倾向于中性色调的冷却侧。上部中音较低的高音区域的轻微撞击会发出声音，声音中闻所未闻的清晰细节，这在显示器上比较常见，可以在Mee Audio P1或PX监听器上显示更多的参考类型调音。上部中频相对平坦，但在3khz处有一个峰值，在7Khz附近有另一个轻微的隆起。耳机为人声和乐器提供了良好的清晰度和存在感，几乎没有可察觉的s or声或纹理。这再次显示了10美元的低要价的许多改进。
关于声音完全诚实，几乎没有什么可抱怨的。 我可以说我实际上更喜欢在旧版NE700m上调整D4。 那些过去的价格是70美元。 我实际上对NuForce NE750和NE850m进行了评论。 这两款耳机的售价都在80美元至120美元左右。 我其实更喜欢在D4上进行调音。
我知道很多头衔最近在Aliexpress销售日购买了一对，我必须告诉你。 你们都有一个非常好的惊喜。 以低的期望进入并像我一样完全惊讶。 这些肯定会让他们感到惊讶。
Pros - Clean confident tuning with excellent quality bass end. An unheard of value for the asking price. Might actually sound nicer than your more expensive earphones. Good imaging and detail.
Cons - Lacks some depth and fullness. You get $10 worth in accessories.
NiceHCK EZAudio D4.
I was forwarded a review sample of the D4 from NiceHCK for review purposes. These can be purchased here. Thanks goes out to Jim for supporting the community and more importantly supporting the hobby.
It has been a while that I have dived into the budget waters of the cheapo iem but once in a while something comes out that just rearranges your thoughts about what can be achieved in the super budget chi fi realm. I am not foreign to what the many OEMs come up with now a days but owning many so called bang for buck iems there is a certain limitation to what sound can do for a $10 IEM right?
So Jim@ NiceHCK suggested I hear the EZAudio D4. They sound really good he says. Ya right. $10 IEM that sounds really good. Where have I heard this before. Hey I am willing to give them a good listen. If they sound good why not?
As far as I know EZAudio D4 is the only product with the name of EZAudio. Might be a line of cheaper iems from a random OEM out of China. The design mimics a design the headfi community should recognize. These look and use identical materials to the oldie but goodie. NuForce NE700m. But that is where the similarities end. These are tuned differently and in fact I will argue is an actual upgrade to the old NE700m more colored tuning.
Driver unit: 10mm Titanizing diaphragm

The D4 is uses an old tried and true design in a single what is described as a 10mm Titanizing driver barel shaped earphone. I am certain they mean Titanium coated diaphragm. Which will give you a clue into what your getting here. Traditionally Titanium coated dynamic earphones have excellent clarity detail and bass. And the D4 does not change much from these aspects but at the price they can’t possibly tuned right. Right?
Well you know sometimes you get stuff that completely surprise you and then there is the D4. I know previous reviews from fellow reviewers have touched on the sheer sound value of these but I am gonna just say. These are CRAZY. And I mean CRAZY sounding for the price. These have a sound that has nothing to do with what your gonna pay for a pair. I hope during recent Aliexpress sales you got yourself a pair. These might actually sound better than your $100 earphones. And this is not an exaggeration.
They certainly look the part of a budget earphone. They don’t scream come look at me like the recent OM1 I reviewed but actually has a very basic cylindrical housing design that most will be familiar with for iems. Looks can and will be deceiving. Basic looks aside it is what is inside the housing and the sound that really matter. I have earphones that I have reviewed for NuForce with the same basic design and so how can a $10 earphone compete with earphones in the $100 range?
To me it is simple. Regardless of price or looks. These guys simply tuned these right. Does this happen on a $10 earphone?. I mean the idea of actually tuning an earphone correct even on a $10 one seems to go against normal conventions and the idea that you get what you pay for. Especially in the audio game.
The first hint of their SQ will be the drivers they are using. Titanium coated drivers are not too common especially for budget fi products. More common on earphones like the Dunu Titan 1 and the like NuForce earphones in the same shape.
On first listen they failed to really impress but the more and more I was listening to them the more I realized something. These actually had a good sound to them. In fact with a good run in and listening to them. It left me kinda speechless.There is no way I am hearing what I am hearing out of these. Never did I think these would come close to the sonics I am hearing from them today. No way. But in deed they do have an excellent sound quality to them.
Build quality is average for budget fi stuff and these aren’t gonna win any awards for build or design on them but wait till you actually hear them. Then you tell me if this is what a $10 iem is supposed to sound like.
Isolation is a bit below average but not terrible. They can be used outdoors with ease and since they have a mic on the cord you can use them with your smart phones to carry out conversations. Tested on my LG phone, vocals come out nice n clear.The braided cord does emit some microphonics but not to the point of annoyance. Worn over the ears eliminates any cord noise.
Sound of the D4 is best described as a balanced tuning leaning to a cooler side of neutral in tone. The mild bump in the upper mids lower treble region throws a sound with an unheard of clean detail in sound that is more common on monitors going for a more reference type tuning exhibited on something like a Mee Audio P1 or PX monitors.Sub bass up to the upper mids is relatively flat but has a peak at 3khz and another mild bump at around 7Khz region. The earphones give a good sense of clarity and presence for both vocals and instruments with little to no perceivable sibilance or grain. Which again shows a lot of refinement for the low asking price of $10.
Treble for the most part stays clean and confident but sounds a touch thin a bit dry but is represented well with the given sound signature. Mids are fairly even handed from lower to upper mids giving excellent vocal clarity and instrument definition. Stage is adequate for the presentation being roughly average in width but lacks some depth to give some fullness to the sounds. The bass on the D4 is balanced nicely and has good tight punch with a good low rumble in the sub bass region that is not too common for budget fi. While bass could have used a slight lift in the 40hz to below it is definitely a good quality bass especially for the price on these.
There is really little to complain about on the sound to be completely honest. I can say I actually prefer the tuning on the D4 over the older NE700m. And those used to go for $70. I actually did a review for the NuForce NE750 and the NE850m. Both earphones hovering around the $80-$120 range. I actually prefer the tuning on the D4.
I know a lot of headfiers recently bought a pair of these for the Aliexpress sales day and I have to tell you. You all are in for a very nice surprise. Go in with low expectations and be completely surprised like I was. These will most definitely amaze for the little cost on them.
