A short comparison of the HD650, HD600, DT880, and DT931
Dear Headfellows,

Yesterday they finally arrived, those long awaited HD650s! I gave them a thorough 36 hours break-in and wanted to share my impressions with you. It&#39s not an extended review though. I leave that up to people like Jude and all the others that soon will have their new toys at home.

For comparison I used a HD600, DT880, and DT931 (modified and driven at 120 Ohm).

Equipment: SONY SCD XB770 (modified), PREHEAD (LM6171), Meier-Audio interconnects

CDs used:

Christy Baron, "I thought about you", Chesky
Fischer-Dieskau and Brendel performing Schubert&#39s "Winterreise", Philips
Jos?Carreras in Ramirez&#39s "Misa Criolla", Philips

BUILD QUALITY
As you all will know by now the HD650 have the same shape as the HD600. Merely colours and the paddings on the headband are different. It has 2 cushions with the HD650 and 4 smaller cushions with the HD600. I like the grey colours of the HD650 but that shiny black that is used on the ear cups could have been a little bit less shiny for my taste.

The cable of the HD650 is thicker than that of the HD600 but the Sennheiser technician that is responsible for the cables (I met him in Berlin a few weeks ago) told me, that the inner conductors are the same for both cables. According to him there shouldn&#39t be any major differences in cable sound.

The Sennheiser cables are attached by small 2 pins interconnects. I personally don&#39t like them and can&#39t see the need in non-professional applications. They do have a tendency to result in poor electrical contact so I find it a pity Sennheiser hasn&#39t come with a better solution.

Build quality of the DT880 is excellent. I don&#39t like the spiral cable very much but that&#39s personal taste.

Build quality of the DT931 is mediocre. The phone provides a real plastic feeling. The standard version also has a spiral cable (mine has a home-made version).

COMFORT
Comfort of the HD650, like that of the HD600, is medium only. The earpaddings aren&#39t very large and these phones have a tendency to clamp (but I admit, I&#39m a bighead and I have big ears!).
The Beyerdynamics are much more comfortable. Big paddings and much less pressure.

SONIC BALANCE
As could be expected the HD600 and HD650 showed great similarity. Warm and easy to listen to. A comfortable sound which places you in the middle of a concert hall. The HD600 has a somewhat stronger upper bass and a little bit more treble. The HD650 seems to have more lower bass and a more seamless transition of the various frequency ranges.

The bass and midrange of the DT880 is surprisingly similar to that of the HD650 but treble is a little bit stronger. My initial impressions of the DT880 when it was launched (half a year ago) were, that it sounded darker than the HD600. I now come to the conclusion that the phone has a stronger lower bass then the Sennheiser and thereby attracts your attention to the lower frequencies, especially at bass heavy music. In reality the treble of the DT880 is a little bit stronger.

The DT931 is a very different kind of headphone. More forwardly balanced and with more energy at the upper frequencies it places you in the first row of the concert hall. A more immediate contact with the musicians is the result.

BASS
I&#39ve always found the bass of the HD600 to be a little bit muddy and slow. Thankfully this has been greatly improved with the HD650. The latter simply is more tight and less resonant and has a better attack. It&#39s in the same league of that of the DT880 but the latter goes deeper. The DT931 has the fastest attack and the best control of all but bass is less dominant as it is on the other phones.

MIDRANGE
The midrange always has been where the HD600 excelled. I&#39m happy to report that the HD650 is even better. More micro-detail, lower coloration, .... There&#39s little left to wish for. The midrange of the DT880 is (almost) similarly good. The midrange of the DT931 is a little bit "stiff" in comparison.

TREBLE
My major complaint with the HD650 is, that its treble is even slightly more recessed than that of the HD600. As a result this phone never will get aggressive on you, but female voices simply lack air and percussion lacks that initial fast attack. The phone sounds slow in comparison to the other models. The HD600 are slightly better but for attack and air the DT880 is clearly superior. Surprisingly, although the HD600 has more treble, the HD650 shows more micro detail. This probably is a result of less distortion that this phone is claimed to have.
The treble of the DT931 is somewhat pronounced. The result is a fast attack and every detail of the performance is made audible.

SPACE
Some of the major clues that give us a feeling of space are the low frequency echoes and reflections that are produced by the walls of the recording location. Since the bass of the DT931 is less strong than that of the other phones it presents less space. The HD600 conveys much more environment but is surpasses in this discipline by the HD650. The bass of the latter simply has a better definition. However, the DT880 is even better in this one.

SOUND LEVELS
When comparing headphones it&#39s very important to listen at the same sound level for each phone. This implied that the volume had to be turned up considerably when listening to the DT880. This phone has a rather lower efficiency. However, the other headphones are not very efficient either and each needs a really good amplifier to shine. Potential buyers should be aware of that. These phones will sound rather miserable right out of portable!

The Sennheisers and the DT880 put their emphasis on the bass. This strong bass easily shades the midrange and treble. Less detailed is heard at the same sound level. Thereby these phones create a tendency to hear at higher sound levels. Especially the HD650 and DT880 have this tendency as distortion (and thereby psychological restraint) is very low. The DT931 has more midrange and upper detail and therefore can be more easily listened to at lower sound levels. It&#39s one of the major reasons that I have the DT931 for personal use.

CONCLUSIONS
The HD650 is a very fine headphone and in various areas it&#39s a clear improvement over the HD600. My only complaints are the (slightly) more recessed treble, the medium level of comfort and that cable connector.

And of course there&#39s its price. The MRSP in Germany is EUR 400,- and I personally find that a lot money. The DT880 has a very similar quality (IMHO) but is much more affordable. To me it also doesn&#39t seem to be so much better than the HD600 that it&#39s worth the +80% in price. However, that&#39s something everybody has to decide for himself



HD650导线比HD600的要大，但是深海的技术人员说其内部结构和HD600是一样的，导线对声音的影响不大。导线是用两个pins interconnect与主体连接的，我个人不喜欢这种连接法。也看不出它对非专业方面的音乐欣赏有什么有利的地方。我发现这种连接方法可能会导致导线接触方面的问题。
DT880的整体结构非常优秀，到是我个人不喜欢他的交叉方式的导线
DT931。。。。。
舒适性
HD650跟HD600差不多，其他的耳机。。。。。
SONIC 平衡
HD600 和 HD650的声音风格有很大的相似性，偏暖，听起来非常舒适。就象在一个音乐会堂中心聆听一样。HD600的高频和高音稍微比HD650强一点。而 HD650似乎低频更好一点。
且各种频率的过度HD650表现比HD600好。
DT880和HD650的低频和中频与有惊人的相似。但是高音部分稍强。当处我听DT880时觉得他的高音比HD600暗。现在我知道这是因为DT880低频吸引了你大部分的注意力而忽略了它的高频。
DT931是另外一种不同类型的耳机。。。。。
比较：
低频
我发现HD600的低频有一些混浊和肥慢。HD650在这一方面有了非常大的改进，明显收缩比较紧，回音（共鸣）减少，更好的冲击。这一点与DT880非常相似，但后者下潜更深。DT931有更快的冲击和其他方面的控制。但频率范围比其他耳机小。
中频
HD600的中频是非常优秀的（怎么版主门都说不行，是不是相对比而言？）HD650的中频比HD650更加优秀，能表现出更多的微观细节和lower coloration。DT的中频跟HD650相似。而DT931则稍微显得刚硬。
高音
我对HD650唯一的一点遗憾就是他的高频相对HD600来说不够recessed。因此它听起来不会让你觉得厌烦。但在initial fast attack时缺凡女声空气密度和percussion。相对与其他的耳机，HD650的声音显得慢。在这一方面HD600稍微好一点的但对冲击和空气密度DT880明显站优。很奇怪，虽然HD600的高频比HD650的稍好（希望不是，HD650应该全面胜出），但HD650解析力却更高。这个可能是在低频方面控制的好从而减少了混乱程度造成的 。
以下两段有点混乱。
SPACE
HD650给我最主要的印象是比较少的频率回响和反射。由于DT931d的低频没有其他耳机强劲。因此他的SPACE感相对少。HD600能表现出更丰富的环境背景， HD650在这一方面又比HD600好。然而DT880好象显得更好。

相对音量
在耳机的评比当中，在同一相对音量的聆听比较是非常重要的。这就是说当你听DT880是应该适当调整他的音量。这个耳机相对efficiency低。其他的耳机的efficiency也不是很好。需要好的二房来推。着一点应该注意。
深海和DT880这些耳机因为强调他们的低频从而在相当程度掩盖了中频和高频。这样在同一音量的情况下很多细节被忽略了，因此这些耳机通常需要在高音量来聆听。特别是对混乱程度相对小的HD650HE和DT880，DT931具有更多的中频响应和高频细节，因此在低音量情况下听就可以了 。
结论
HD650是一个非常优秀的耳机，相对HD600他在许多方面有了很大的提高，我唯一的遗憾是是他的(slightly) more recessed treble ，舒适程度和耳机线的连接接口。
当然，他的价格是比较贵的，400欧。DT880有着差不多相同的质量才XXX米，性价比更高点。对我来说，他并不比HD600好多少却多了80%的价钱。但是想一想音质在这个程度上在提高一点也是要付出相当代价的。HD650，期待中。

决定了,明天要抢银行.

翻译一下。

看来880的型价比最高（原文说880与650有相同的素质）
650与600比低音更好但好像声场小了（我认为650还没保开）但低音的改进足以让600的烧友欢喜雀跃。

以后要多上英文网站了,花了我好几个小时.呵呵

ansys1998

为什么相同类型国外的东东要比国内低?是不是有等级区分的,象日本进到我过的耳机啊,随身听等?

ansys1998

刚才说错了,是高.

看来我选择880是对的。
