优点 - 优秀的SQ远远超出其价格点，良好的构建质量，舒适

 

缺点 -QC问题与低音通风口导致通道不平衡（可校正），包括耳塞在佩戴电缆时无效，驾驶员在通风口被覆盖时弯曲（例如当推入耳朵时），麦克风/播放控制不明显

 

简介/免责声明：

  

EZAudio D4是一款带有单个10mm动态驱动器的IEM，在本次评测时零售价为10.90美元，将于11/11/2018发售，售价为7.99美元。 D4由AliExpress的NiceHCK音频商店出售。 我以0.10美元的促销价购买了D4以换取这次审查。 我对D4的看法是我自己的，我会努力客观地回顾D4。

资源

 

我使用了以下来源的EZAudio D4：

小米Redmi Note 4 Global> EZAudio D4

Windows 10 PC> JDS实验室元素> EZAudio D4

Windows 10 PC> Hidizs AP60II> EZAudio D4

我用Spotify Premium高质量流媒体，320kbps的Google Play音乐流和本地FLAC测试了这些耳机。

包装和配件

  

EZAudio D4采用简单的矩形白色纸盒，正面有蓝色制造商标志。 包装盒上的文字主要是中文，但列出了罗马字符的型号，频率范围，互连类型，驱动程序大小和阻抗。 在这个盒子里面是一个EZAudio品牌的半刚性拉链便携包，里面装有IEM，一个登山扣和耳塞选择。 对于11美元的IEM，这种情况非常高，看起来与NICEHCK EP35除了品牌之外的情况相同。 EZAudio D4配有一套耳塞（黑色硅胶[小，中，大]。

建立质量/设计

  

D4的外壳设计是NuForce NE-700M的克隆，带有桶形金属外壳和短圆形喷嘴。 喷嘴由金属网覆盖，并有一个相当大的唇口，以防止耳塞脱落。 金属外壳周围有一个塑料环，电缆从每个耳机上出来。 电缆光滑且橡胶状，直至Y型分体，然后织物覆盖到L形3.5mm插孔。 右耳机线有麦克风。 该电缆有一个短项链，从右侧耳机线缆的Y型分离器一直到麦克风的底部。 金属外壳在耳朵表面上用塑料抛光金属。 D4在外部面板上有一个用于动态驱动器的通风口。 我有经验的驾驶员弯曲D4，同时将IEM深深地插入我的耳朵，这很难做到没有覆盖这个通风口。

FIT / COMFORT / ISOLATION

  

当穿戴电缆时，D4的插入深度非常浅，因为外壳很短，导线会抵住耳朵的对角线。 当D4穿着电缆时，所包含的耳塞基本没用，因为配合很浅。 我发现戴上D4电缆可以增加插入深度和更好的密封性，即使是库存耳塞也是如此。 但是，我强烈建议使用D4的第三方双法兰或三法兰耳塞。

当电缆穿线时隔离高于平均值，但在电缆穿线时低于平均值。

机筒外壳的直径足够短，D4非常舒适，无论是电缆连接还是电缆封闭。

声音

  

EZAudio D4s具有整体明亮的声音特征，上部中频提升。

凭借良好的密封性，D4具有内敛但权威的低音响应，具有出色的低音延伸。对于这个价格点而言，低音令人惊讶的质感。有大量的中低音猛击，快速衰减。
编辑：我自己和其他人的测量显示低音区域有相当大的通道不平衡，这可能是由于QC差，以确保一致的低音通风口尺寸和形状。这是可以纠正的。

与低音相比，较低的中音略微凹陷，但是尽管有低音出血，但是男性的声音仍然足够清晰。从1k逐渐上升到刚刚过去的5k，这给了D4很多存在感。中上部可能有点刺耳，对女性的声音有点咄咄逼人，并且有一些s。声。

与中高端相比，高音是凹陷的，但直到超过15k才开始急剧下降。较低的高音有点颗粒感。 10-12k区域有大量的能量，增加了闪光。

声场宽度和深度是平均的。该价格点的仪器分离远高于平均水平。

测量

 

我使用乙烯管接头使用Dayton iMM-6麦克风进行测量。 mic cal文件设计用于9k共振峰值，然而，为了保持一致性，我使用泡沫耳塞在相同的插入深度进行了所有测量，因此可能在9k下降，实际上并不存在。

COMPARISONS

UiiSii CM5（绿色）vs EZAudio D4（红色）

 

UiiSii CM5是价值16美元的IEM，配有单个石墨烯喷涂动态驱动器。 CM5比D4明显更加V形，低音量更多，低音更高。 CM5具有更好的低音纹理和更多的中低音猛击。 D4听起来更加空气。 与较高音量的D4相比，CM5的声音听起来不那么刺耳，并且不那么s。声。 D4具有更好的仪器分离。 CM5的声场稍大。

Mixcder X5（紫色）vs EZAudio D4（红色）

Mixcder X5售价12美元，带有单个动态驱动程序。 X5是一个明显更温暖的IEM，具有较少的中上部存在。 D4具有更好的低音清晰度。 相比之下，X5上的低音听起来很混乱。 D4听起来更加空气。 整个X5更加轻松。 在较高音量下，X5的声音不如D4，并且不那么刺耳。 D4具有更好的仪器分离。 X5的声场稍大。

Fiio F1（蓝色）vs EZAudio D4（绿色）

 

Fiio F1售价10美元，配备单动态驱动器。 F1具有更多的低音量，但与D4相比听起来很浑浊，关节和纹理更差。 F1的低中频比D4更加黯然失色。 F1有一个奇怪的高峰，大约1.8k，这使得中音声音嘶哑。 F1有更多的高音滚动，听起来不那么详细。 D4听起来更加空气。 F1不那么s。不安。 D4具有更好的仪器分离。 它们具有相似的声场大小。

Mee Audio Pinnacle P1（蓝色）vs EZAudio D4（绿色）

 

389/5000

鉴于价格差异不是公平的比较，但考虑到他们的频率响应有多相似，我觉得将D4描述为穷人的P1是合理的。 P1整体上更加分辨，具有更加细致的高音区域和稍微更加内敛的中上部。 P1具有更大的声场和更好的乐器分离。

放大要求和来源配对

  

在阻抗为32欧姆，灵敏度为99dB时，智能手机可以充分驱动D4。 我不觉得他们因为有更多的动力而明显受益。 我没有注意到任何关于D4的嘶嘶声。

结束语

EZAudio D4的价格令人惊讶。 强烈推荐。 你可以在这里购买D4。

1. Pros - Excellent SQ far beyond its price point, good build quality, comfortable

   Cons - QC issues with bass vents leading to channel imbalance (correctable), included ear tips are useless when worn cable-down, driver flex when vents are covered (such as when pushing into ears), mic/playback control not obvious

   INTRODUCTION/DISCLAIMER:
   
   The EZAudio D4 is an IEM with a single 10mm dynamic driver that retails for $10.90 at the time of this review and will be on sale on 11/11/2018 for $7.99. The D4 is sold by the NiceHCK Audio Store on AliExpress. I purchased the D4 at a promotional price of $0.10 in exchange for this review. My thoughts about the D4 are my own and I will strive to review the D4 objectively.
   
   SOURCE
   
   I have used the EZAudio D4 with the following sources:
   
   Xiaomi Redmi Note 4 Global > EZAudio D4
   
   Windows 10 PC > JDS Labs The Element > EZAudio D4
   
   Windows 10 PC > Hidizs AP60II > EZAudio D4
   
   I have tested these headphones with Spotify Premium high-quality streaming, Google Play Music streaming at 320kbps, and local FLAC.
   
   PACKAGING AND ACCESSORIES
   
   The EZAudio D4 comes in a simple rectangular white paper box with the manufacturer’s logo in blue on the front. The text on the box is mostly in Chinese, but lists the model, frequency range, interconnect type, driver size, and impedance in Roman characters. Inside this box is a EZAudio-branded semi-rigid zippered carry case containing the IEMs, a carabiner, and the eartip selection. For an $11 IEM the case is very high quality and seems identical to the case from the NICEHCK EP35 apart from the branding. The EZAudio D4 comes with one set of eartips (black silicone [Small, Medium, Large].
   
   BUILD QUALITY / DESIGN
   
   The D4’s housing design is a clone of the NuForce NE-700M, with barrel-shaped metal housings and short circular nozzles. The nozzles are covered by metal mesh and have a sizable lip to prevent eartips from coming off. The metal housings have a plastic ring around their circumference from which the cable exits on each earpiece. The cable is smooth and rubbery down to the Y-split, then fabric-covered down to the L-shaped 3.5mm jack. The right earpiece wire has a mic. The cable has a choker that comes up from the Y-split up to the bottom of the mic on the right earpiece cable. The metal housings polished metal with plastic on the ear-facing surface. The D4 has a single vent for the dynamic driver on the exterior faceplate. I have experienced driver flex with the D4 while inserting the IEMs deeply into my ears, which is hard to do without covering this vent.
   
   FIT / COMFORT / ISOLATION
   
   When worn cable-down the D4 has very shallow insertion depth because the housings are so short that the wires catch against the antitragus of the ear. The included eartips are essentially useless when the D4 is worn cable-down because the fit is so shallow. I found wearing the D4 cable-up allowed for increased insertion depth and much better seal, even with the stock eartips. However, I highly recommend third-party dual- or triple-flange eartips with the D4.
   
   Isolation is above average when worn cable-up but below average when worn cable-down.
   
   The diameter of the barrel housings is short enough that the D4 is very comfortable worn either cable-up or cable-down.
   
   SOUND
   
   The EZAudio D4s have an overall bright sound signature with a lifted upper midrange.
   
   With a good seal the D4 has a restrained but authoritative bass response with excellent sub-bass extension. Bass is surprisingly textured for this price point. There is a good amount of mid-bass slam with fast decay.
   Edit: Measurements by myself and others show a sizable channel imbalance in the bass region which is likely due to poor QC with regards to ensuring consistent bass vent size and shape. This is correctable.
   
   Lower mids are slightly recessed compared to the bass but male vocals are adequately clear despite some bass bleed. There is a gradual rise from 1k to just past 5k which gives the D4 a lot of presence. The upper midrange can be a bit harsh and overbearing with female vocals, and there is some sibilance.
   
   Treble is recessed compared to the upper midrange but does not begin to roll off dramatically until past 15k. Lower treble is a little grainy. There is a good amount of energy in the 10-12k region which adds sparkle.
   
   Soundstage width and depth are average. Instrument separation is well above average for this price point.
   
   MEASUREMENTS
   
   My measurements were conducted with a Dayton iMM-6 microphone using a vinyl tubing coupler. The mic cal file is designed to be used with a 9k resonance peak, however, for the sake of consistency I have conducted all my measurements at the same insertion depth using foam eartips, so there may be a dip at 9k that is not actually there.
   
   COMPARISONS
   
   UiiSii CM5 (green) vs EZAudio D4 (red)
   
   The UiiSii CM5 is a $16 IEM with a single graphene-sprayed dynamic driver. The CM5 is significantly more V-shaped than the D4, with much more bass quantity and a more elevated lower treble. The CM5 has better bass texture and more mid-bass slam. The D4 sounds airier. The CM5 is less harsh sounding than the D4 at higher volumes and is less sibilant. The D4 has better instrument separation. The CM5 has a slightly larger soundstage.
   
   Mixcder X5 (purple) vs EZAudio D4 (red)
   
   The Mixcder X5 is a $12 IEM with a single dynamic driver. The X5 is a significantly warmer IEM with less upper midrange presence. The D4 has better bass articulation. The bass on the X5 sounds muddy in comparison. The D4 sounds airier. The X5 is more relaxed sounding overall. The X5 is less harsh sounding than the D4 at higher volumes and is less sibilant. The D4 has better instrument separation. The X5 has a slightly larger soundstage.
   
   Fiio F1 (blue) vs EZAudio D4 (green)
   
   The Fiio F1 is a $10 IEM with a single dynamic driver. The F1 has more bass quantity but sounds muddy in comparison to the D4, with worse articulation and texture. The F1’s lower midrange is even more recessed than the D4s. The F1 has a weird peak at about 1.8k that makes the midrange sound shouty. The F1 has a much more rolled off treble and sounds less detailed. The D4 sounds airier. The F1 is less sibilant. The D4 has better instrument separation. They have similar soundstage sizes.
   
   Mee Audio Pinnacle P1 (blue) vs EZAudio D4 (green)
   
   Not a fair comparison given the price differential but given how similar their frequency responses are I feel justified in describing the D4 as a poor man’s P1. The P1 is more resolving overall, with a more detailed treble region and a slightly more restrained upper midrange. The P1 has a larger soundstage and better instrument separation.
   
   AMPLIFICATION REQUIREMENTS AND SOURCE PAIRING
   
   At an impedance of 32 ohms and a sensitivity of 99dB, the D4 can be adequately driven by a smartphone. I do not feel that they benefit noticeably from having more power on tap. I did not notice any hiss with the D4.
   
   CLOSING WORDS
   
   The EZAudio D4 is astonishing for the price. Highly recommended. You can purchase the D4 here.
