You can never get enough of something that’s really good, and with a price tag of 330 USD, DEVA Pro refines on the DEVA that I enjoyed greatly back in 2020, and the new model now comes with an R2R Bluetooth DAC Chip, new drivers from HIFIMAN, and Balanced connectors too, so you can use balanced cables, including a TRRS cable for the left earcup. This means that I got to compare the new DEVA Pro (330 USD) to the original HIFIMAN DEVA (300 USD) throughout the entire review, but also to Avantone Pro Planar (450 USD), and Harmonic Dyne Zeus (350 USD) and Verum One MK2.

好东西永远都享受不够。DEVA Pro的标价为330美元。它在2020推出的、我非常喜欢的DEVA的基础上进行了改进，现在的新型号配备了R2R蓝牙DAC芯片，HIFIMAN的新耳机单元，还有平衡连接口，所以你可以使用平衡线，包括TRRS线直接插入左耳罩。这意味着在整个评测过程中，我将新的DEVA Pro（330美元）与原版的HIFIMAN DEVA（300美元）进行比较，同时也与Avantone Pro Planar（450美元）、Harmonic Dyne Zeus（350美元）和Verum One MK2进行对比测评。

Introduction

HIFIMAN is a large company from China, and they are one of those unique companies with personality, excellent warranty and customer support policy. Despite there being old and well established companies like Sennheiser, Beyerdynamic, Denon, FiiO who are unable to offer proper customer support if you purchase their products directly from them (you need to get them locally for support), there are also companies like HIFIMAN who love to be there for you. There have been some times in the past when warranty was slightly complicated for HIFIMAN too, but as they grew, they can now offer the level of support expected when purchasing a high-end flagship headphone. If you ever happen to reach a point where you will need warranty, you will be directed to sending the headphone to an easily reachable address, and you will receive a replacement really quickly, the turnaround time for most clients having been about 2-4 weeks so far. 

It should be noted that I have absolutely no affiliation with HIFIMAN, I am not receiving any incentive for this review or to sweeten things out. I’d like to thank HIFIMAN for providing the sample for this review. Every opinion expressed is mine and I stand by it. The purpose of this review is to help those interested in HIFIMAN DEVA Pro find their next music companion. 

简介

HIFIMAN是一家来自中国的大公司。它是那种独特的公司，具有个性，优秀的保修和客户服务政策。尽管有像森海塞尔、拜亚动力、天龙、飞傲这样的老牌公司，如果你直接从他们那里购买产品，他们无法提供适当的客户支持（你需要在当地购买才能获得支持），但也有像HIFIMAN这样的公司喜欢为你服务。过去有一段时间，HIFIMAN的保修也略显复杂，但随着他们的成长，他们现在可以提供购买高端旗舰耳机时应有的技术支持水平。如果你碰巧到了需要保修的时候，你会被告知把耳机寄到一个不太远的地址，你会很快收到替换品，到目前为止，大多数客户的周转时间大约是2-4周。

我要特别声明，我与HIFIMAN绝对没有任何关系，我没有因为这次评论而收到任何奖励，也没有为了甜头而给测评包上糖衣。我想感谢HIFIMAN为这次测评提供的样品。我所表达的每一个观点都是我自己的，我一直坚持这样做。本测评的目的是帮助对HIFIMAN DEVA Pro感兴趣的人找到他们的下一个音乐伴侣。

Packaging

First things first, let’s get the packaging out of the way:

I like the fact that HIFIMAN didn’t cheap on the package of DEVA Pro, compared to the package of the original DEVA.

In fact, they include all of the basic necessities for using DEVA Pro, the Bluemini R2R Himalaya Bluetooth receiver, cables to use them wired, charging cable for the mini bluetooth receiver, and crispy paperwork. The headphones are also seated and presented nicely, in a silk-like material and sponge to keep them safe. 

包装

首先，让我们把包装的事情说清楚。

我很高兴HIFIMAN在DEVA Pro的包装上没有吝啬，尤其与原版DEVA的包装相比。

事实上，他们提供了所有使用DEVA Pro的基本必需品：Bluemini R2R喜马拉雅蓝牙接收器、有线使用的耳机线、迷你蓝牙接收器的充电线、以及漂亮的说明书和文件。耳机的包装和摆放也很好，用类似丝绸的材料和海绵来保持它们的安全。

Build Quality/Aesthetics/Fit/Comfort 

DEVA Pro is a whole new level of headphone, planar magnetic and bluetooth enabled, better than the original DEVA, and surely better than the HE400SE and Sundara it is made to compete with. In fact, throughout the entire midrange category, no headphone comes with a bluetooth amplifier as good as DEVA Pro. As we will see, this also leads to a disadvantage with DEVA Pro, but first, let’s explore the headphones. 

HIFIMAN went with a more color neutral approach for DEVA Pro, with a silver and black color scheme, making DEVA Pro sleeker and more elegant than the original DEVA. They also made DEVA Pro better built than the original DEVA, and where the original felt a bit plasticky, the PRO variant feels full metallic and better built. HIFIMAN didn’t change the overall specifications, and both have an 18 OHM impedance, along with an extremely low SPL of 93.5 dB, making both the original DEVA and DEVA Pro hard to drive. The Bluetooth connection stability of the Bluemini is excellent, to the point where doing my usual test, placing the smartphone in a backpack, and covering it in a few blankets, or palming it, results in still a strong connection. 

制造质量/美观/贴合度/舒适度

DEVA Pro是一款创建了个全新级别的耳机，具有平板单元和蓝牙功能，比原来的DEVA更好，当然也比竞争对象HE400SE和Sundara更好。事实上，在整个中端类别中，没有任何一款耳机的蓝牙放大器像DEVA Pro一样棒。正如我们将看到的，这也导致了DEVA Pro的劣势，但首先，让我们探讨一下这款耳机。

HIFIMAN为DEVA Pro采用了更加中性的颜色，银色和黑色的配色方案，使DEVA Pro比原来的DEVA更加现代和优雅。他们还使DEVA Pro的结构做得比原版的DEVA更好；原版的DEVA感觉有点塑料，而PRO的变体感觉是全金属的，结构更好。HIFIMAN没有改变整体规格，两者都有18欧姆的阻抗，加上93.5分贝的很低的声压级，使得原版DEVA和DEVA Pro都难以驱动。Bluemini的蓝牙连接稳定性非常好，以至于在做我的常规测试时，把智能手机放在背包里，用几张毯子盖住，或者用手掌盖住，结果仍然是连接信号很强。

Both the original and the new DEVA Pro have support for LDAC, aptX HD, aptX, AAC and SBC, but the new Himalaya Bluemini R2R Receiver has vastly better overall specifications than the original Bluemini. We’re talking about a -120dB SNR for the DAC, a THD of 0.0022, and an energy efficiency of 20mW. What this means is that the new Bluemini R2R consumes very little, brings very clean and clear sound, and has the same shape and ergonomics as the original bluemini. For phone calls, Bluemini has a background hiss that’s audible sometimes, and you can use the button to end a call, for pressing play or pause during song playback. The same hiss is audible while the turn on / turn off voice speaks, but it is not audible during music playback at all, Bluemini being not only perfectly capable of driving DEVA Pro but having extremely low noise, great control and overall sonic quality. 

HIFIMAN kept the USB DAC function for the Himalaya Bluemini R2R, and we can still use it cabled, via Bluetooth to power DEVA Pro, and DEVA Pro can take both two TRS 3.5mm cables, or one TRRS 3.5mm cable in its left earcup (this is extremely rare though, you’ll need a custom 3.5mm TRRS cable made for them). The new R2R Bluemini also has exceptional battery life, of about 8 hours on paper and 6 hours tested by me, at loud to very loud volumes, aptX, LDAC, and some phone talk. The new blue mini module has a microphone as well, and it can be used to take phone calls, having one of the best phone qualities for the microphone, although it doesn’t have a good noise cancelling algorithm, so wind noise will be audible. DEVA Pro being open, I suspect you won’t be using them where there’s windy weather or lots of noise anyways. The R2R Bluemini Receiver always runs in balanced TRRS 3.5mm, and you need to make sure that you always connect it to the left earcup, otherwise you might short it out. 

原版的DEVA和新的DEVA Pro都支持LDAC、aptX HD、aptX、AAC和SBC，但新的喜马拉雅Bluemini R2R接收器的整体规格大大优于原有的Bluemini。我们谈论的是解码器的-120dB信噪比，THD为0.0022，能源效率为20mW。这意味着新的Bluemini R2R能耗非常少，带来非常干净和清晰的声音，并且具有与原来的Bluemini相同的形状和使用感受。对于打电话，Bluemini有一个背景嘶嘶声，有时可以听到；你可以使用按钮来结束通话，用于在歌曲播放时按下播放或暂停。在打开/关闭的语音提示响起时，同样的嘶嘶声可以听到，但在音乐播放时完全听不到。Bluemini不仅可以充分驱动DEVA Pro，而且噪音极低，控制力强，整体音质好。

HIFIMAN为喜马拉雅Bluemini R2R保留了USB DAC功能，我们仍然可以有线和蓝牙两种方法链接。DEVA Pro可以插入两个TRS 3.5毫米线，或一个TRRS 3.5毫米线插入左耳罩（这种线是非常罕见的，你需要定制）。新的R2R Bluemini也有非常好的电池寿命，纸面上约8小时，我测试了下来是6小时，在大到非常大的音量之间，aptX、LDAC连接，还打了一些电话。新的Bluemini模块也有一个麦克风，它可以用来接电话，算是最好音质的麦克风，虽然它没有一个好的降噪算法，所以风噪能听见。DEVA Pro是开放式的，我觉得你反正不会在有风的天气或有很多噪音的地方使用它。R2R Bluemini接收器有平衡TRRS 3.5毫米插头输出，你需要确保你总是把它连接到左耳罩，否则可能会导致短路。

At the headphone level, DEVA Pro is extremely comfortable, lightweight, and a pleasure to wear. They are lighter than most flagships, lighter than Audeze LCD-2C, lighter than Verum One MK2, and they’re as comfortable as the original DEVA, more comfortable than Sundara. The only headphone I reviewed that is more comfortable than DEVA Pro by a good margin is HIFIMAN’s Arya Stealth, which has larger earpads, slightly less clamping force, and a looser fit. The normal cable for using them is flexible, and of a really good quality. Feels more reliable than the cable that HE400SE comes with. 

The review has the word Stealth in the title, because DEVA Pro uses the new HIFIMAN Technology for their drivers, also seen in my review of the HIFIMAN Arya Stealth, technology which makes the magnets invisible to sound. Basically, the new way the magnets are designed allows for sonic waves to pass through them without generating interference, leading to a more clean overall sound. We will see below if it works as intended, in the sound quality part of today’s review. 

在耳机层面，DEVA Pro非常舒适，重量轻，佩戴起来很舒服。它们比大多数旗舰产品更轻，比如Audeze LCD-2C，比如Verum One MK2，而且它们和原版的DEVA一样舒适，比Sundara也更舒适。我评测的唯一一款比DEVA Pro更舒适的耳机是HIFIMAN的Arya Stealth，它的耳垫更大，夹持力略小，而且更宽松。它们的耳机线很灵活，而且质量非常好，感觉比HE400SE自带的线更可靠。

这篇测评在标题中使用了隐形一词，因为DEVA Pro在他们的单元上使用了新的HIFIMAN技术；在我对HIFIMAN Arya Stealth的测评中也看到了这一技术，它使磁铁对音波“不可见”。基本上，磁铁的新设计方式允许声波通过它们而不产生干扰，导致整体声音更加干净。我们将在今天的测评中的音质部分看到它是否如愿以偿。

Sound Quality

I usually leave the pairings part of a review for the Build Quality, or I make a different part about pairing, but HIFIMAN DEVA Pro is unique in this aspect, as it comes with the Bluemini that it is supposed to be used with. This means both that it sounds quite great with it, but also that you may end up always using it wireless. Even using high-end DAPs like iBasso DX300, Astell & Kern SE180, Lotoo PAW 6000 and Desktop sources like Cyrus One Cast and Violectric HPA V340, I still find the Bluemini enjoyable, and almost in line with all the other high-end sources. HIFIMAN really optimised the bluetooth receiver to give an impressive sonic performance with DEVA Pro, and they didn’t fail to deliver. DEVA Pro is hard to drive and needs high-end sources to sound their best. No smartphone will be able to drive it properly, and most entry-level portables as well as smartphones won’t get them very loud. 

With all of that out of the way, I’ve used DAPs and high-end sources half of the time, and the Bluemini half of the time for taking the sound quality notes, and to keep things fair. The overall sonic presentation can be described as lightweight, impactful, wide and well separated, neutral-natural in tuning, with great extension in both the treble and the bass, and with an amount of warmth in the midrange. 

声音质量

我通常会在评论中把蓝牙配对部分留给制造质量，或者写一个关于配对的章节，但HIFIMAN DEVA Pro在这方面是独一无二的，因为它带有Bluemini，它应该与之一起使用。这意味着它的声音听起来相当棒，但也意味着你最终可能从来都是以无线方式使用它。即使使用高端播放器，如iBasso DX300、Astell & Kern SE180、Lotoo PAW 6000和台式音源，如Cyrus One Cast和Violectric HPA V340，我仍然觉得Bluemini很悦耳，而且几乎与所有其他高端音源保持在一个级别。HIFIMAN确实对蓝牙接收器进行了优化，以使DEVA Pro具有令人印象深刻的音质表现，他们也没有辜负这个使命。DEVA Pro很难驱动，需要高端音源才能发出最佳声音。没有智能手机能够正确地驱动它，大多数入门级的便携设备以及智能手机都不会让它们足够大声。

说了这么多，我一半时间使用播放器和高端音源，一半时间使用Bluemini来做音质记录，以保持公平。整体的音质表现可以说是轻盈、有冲击力、宽阔、分离度好，调音中性自然，高音和低音都有很好的延伸，中音也有一定量的温暖度。

The bass of HIFIMAN DEVA Pro is actually better than that of the original, with a better sub bass extension, hit and impact. The overall bass is more nuanced and fuller, but it doesn’t feel much higher in quantity per se, so the total overall tonal balance is similar to the one we’ve seen with DEVA. It is much better than the bass found on HIFIMAN Sundara and HE400SE, and higher in quantity as well. The upper bass is more enhanced on the original DEVA, and it feels natural on DEVA Pro, with some extra body and thickness for all instruments, but without the upper bass coloring the mids. 

In fact, the midrange of DEVA Pro is quite neutral, clean and detailed, with a good amount of impact and width. DEVA Pro is right behind HIFIMAN Arya Stealth, and it is currently one of the most open sounding headphones out there, and the widest sounding one among its price class (350 USD). Imaging and detail are also great, I can notice details with DEVA Pro that I usually am only able to notice with high-end flagships. The thing here is that DEVA Pro is not analytical, but musical and natural, so you never have to worry about the sound being too harsh. They are quite forgiving in fact, and DEVA Pro is made for enjoyment not for music work. 

The treble is forgiving, well extended, slightly bright in tonality, and also natural in texture. This means that there is a good amount of treble, and it can be enough for some to call the sound bright, but it is never harsh, and the natural texture means that all instruments, cymbals, everything sounds as it sounds naturally, without euphemisms or added aggressivity. 

HIFIMAN DEVA Pro的低频实际上比原版DEVA的要好，有更好的低频延伸、瞬态和冲击力。整体的低频更细致，更饱满，但它本身并没有感觉到有更多的量，所以总的整体调音平衡与我们的原版DEVA相似。它比HIFIMAN Sundara和HE400SE上的低频好得多，而且量也更大。在原版DEVA上，上层的低频更加突出，而在DEVA Pro上感觉很自然，所有的乐器都有一些更好的的形体和厚度，但没有低频上部给中频染色。

事实上，DEVA Pro的中频是相当中性的，干净而细致，具有良好的冲击力和宽度。DEVA Pro紧随HIFIMAN Arya Stealth之后，是目前听起来最开放的耳机之一，也是同价位（350美元）中听起来最宽阔的耳机。结像和细节也很好，我可以注意到DEVA Pro的细节，而我通常只能注意到高端旗舰产品的细节。重要的是，DEVA Pro不是那种分析性的声音，而是音乐性的和自然的，所以你永远不必担心声音会太刺耳。事实上，它是相当宽容的，DEVA Pro是为享受而不是为音乐工作而设计的。

高频是宽容的，有很好的延伸性，音色略微明亮，而且音色也很自然。这意味着有一个量很足的高频，足以让一些人称其为明亮，但它从不刺耳；自然的音色意味着所 有的乐器、铙钹、等等听起来都是自然的，没有遮掩，也没有增加攻击性。

Comparisons 

HIFIMAN DEVA Pro vs Avantone Pro Planar (330 USD vs 450 USD) – We have a monitor, that is more expensive than DEVA Pro, against a bluetooth headphone, but both are planars and both are open back. In fact, the entire comparisons part has only open back headphones, to avoid unfair comparisons. The overall comfort is similar, with Avantone PRO Planar being heavier, but still having large pads and good comfort, except for when walking where DEVA Pro is more stable. The sound is thicker, warmer, smoother and more punchy, with more bass on Avantone PRO Planar, while DEVA Pro has more dynamics, is more airy, wider, with more instrument separation, with a lighter and snappier sound. Avantone PRO Planar is more forgiving than DEVA Pro and needs some boost in the highs to match DEVA Pro’s sound that has more treble and less bass. 

HIFIMAN DEVA Pro vs Verum One MK2 (330 USD vs 300 USD) – Verum One MK2 is an ironic situation, it is so easy to drive, having a low impedance, that some sources can struggle to keep them going. Verum One is heavier, and sits tighter on the head. By comparison, DEVA Pro sounds more open, it is wider, has more instrument separation, and is more warm in the midrange. Verum One the second sounds more neutral, with less emphasis on bass, and a more bright treble, they both have great detail and extension, but DEVA Pro is more musical, more warm and easier to listen to, with a smoother treble, where Verum One MK2 is more neutral, cleaner, but has less bass quantity and reveals the bad side in poor recordings easier than DEVA Pro, which can be more forgiving. 

HIFIMAN DEVA Pro vs Harmonicdyne Zeus (330 USD vs 350 USD) – Zeus doesn’t come with a driving receiver, so you will need something to drive it, and it won’t be any luck if you’re a smartphone kind of guy either, as Zeus eats a lot of power. If both are driven well, Zeus will sound thicker, warmer, and more bassy, with a more intimate and focused soundstage. By comparison, DEVA sounds more open, wider in the soundstage, with more detail, it is cleaner and generally much more enjoyable with atmospheric music. Zeus sounds more forward and direct. The treble has better extension and is more airy on HIFIMAN DEVA Pro, but it is smoother on Zeus. DEVA Pro sounds more neutral, which can make music brighter, but also reveals more detail in the bass, where DEVA Pro has more nuance. 

 对比

HIFIMAN DEVA Pro vs Avantone Pro Planar (330 美元 vs 450 美元) - 我们在拿比DEVA Pro更贵的监听耳机，与一个蓝牙耳机在相比较，但两者都是平板耳机，都是开放式的。事实上，整个比较部分只有耳机本身，以避免不公平。整体舒适度相似，Avantone PRO Planar更重，但仍有大耳垫和良好的舒适度，除了走路时，DEVA Pro会更稳定。声音方面，Avantone PRO Planar的声音更厚实，更温暖，更平滑，更有冲击力，低音更强，而DEVA Pro的动态更强，更大气，更宽，乐器分离度更高，声音更轻盈，更爽快。Avantone PRO Planar比DEVA Pro的宽容性更高，而且需要在高频部分进行一些提升，以接近DEVA Pro的声音，因为DEVA的高频更多，低频更少。

HIFIMAN DEVA Pro vs Verum One MK2 (330 美元 vs 300 美元) - Verum One MK2是一个有意思的情况，它很容易驱动，具有低阻抗，但一些音源又会很难让它们好听。Verum One更重，而且在头上夹得更紧。相比之下，DEVA Pro听起来更开放，更宽，有更多的乐器分离，而且中频更温暖。Verum One听起来更中性，不太强调低音，高音更明亮，它们都有很好的细节和延伸，但DEVA Pro更有音乐感，更温暖，更容易听，高音更平滑；Verum One MK2更中性，更干净，但低音量少，比DEVA Pro更容易暴露出不良录音的瑕疵；DEVA Pro可以更宽容。

 HIFIMAN DEVA Pro vs Harmonicdyne Zeus (330 美元 vs 350 美元) - Zeus没有附带蓝牙耳放，所以你需要有东西来驱动它，如果你是智能手机直推的那种人，也不会有什么运气，因为Zeus需要很大的驱动力。如果两者都能很好地被驱动，Zeus听起来会更厚实、更温暖、更有气势，音场更贴近、更集中。相比之下，DEVA听起来更开放，声场更宽，有更多的细节，更干净；一般来说，大气的音乐更令人愉快。Zeus听起来更前卫和直接。高音在HIFIMAN DEVA Pro上有更好的延伸，更有空气感，但在Zeus上则更平滑。DEVA Pro听起来更加中性，这可以使音乐更加明亮，但也可以在低频中显示出更多的细节，在低频中DEVA Pro有更多的韵味。

Value and Conclusion 

All in all, DEVA Pro has one of the best values for a mid range headphone I’ve seen to date. The headphone itself is amazingly comfortable, sounds great, and comes with a bluetooth receiver that’s actually as capable to drive them as most high-end flagship players or high-end desktop amplifiers. This makes DEVA far better than most competitors, and gives it a full edge for portability, although the open-back design takes some of that portability away from it and shifts the focus to the sonics. 

Speaking of the sonics, DEVA is one wide sounding, warm, detailed, clean and sparkly headphone, to the point where I have to add it to Audiophile-Heaven’s Hall Of Fame, as one of the best headphones I reviewed to date for around 350 USD. 

At the end of today’s review, if you ever found yourself frustrated with planar magnetic headphone for their hard to drive nature, if you don’t want to invest in a cumbersome audiophile setup, but if you still want that audiophile wide, atmospheric sound with a deep bass, clean treble, detailed midrange and musical signature, HIFIMAN DEVA Pro Planar Magnetic Headphones are easily ones of the easiest to recommend out there. 

价值和结论

总而言之，DEVA Pro是我迄今为止见过的最有性价比的中端耳机之一。耳机本身惊人的舒适，听起来很好，并配有一个蓝牙解码放大器，实际上能够像大多数高端旗舰播放器或高端桌面放大器一样驱动耳机。这使得DEVA远远优于大多数竞争对手，并使其在便携性方面具有充分的优势，尽管开放式设计使其失去了一些便携性，并将重点转移到音质方面。

说到音质，DEVA Pro是一款声音宽广、温暖、细致、干净，带着闪光的耳机，以至于我不得不把它加入Audiophile-Heaven的名人堂，作为我迄今为止评测的350美元左右的最佳耳机之一。

在今天的测评最后，如果你曾经发现自己对平板耳机难以驱动的特质感到沮丧，如果你不想投资于繁琐的发烧设备，但如果你仍然想要那种发烧级的宽广、大气的声音，有深沉的低频、干净的高频、细致的中频和音乐鲜活的特质，HIFIMAN DEVA Pro平板耳机是最推荐的耳机之一。
