遇见IER-M7和M9，索尼的多单元动铁舞台监听耳塞
虽然索尼是考虑到职业音乐人的需求来制造这些耳塞的
它们的实用、舒适的设计也全面满足了音乐爱好者们的需要
M7的外壳是塑料的
而M9的是镁合金的
但这两副耳塞都使用了镁合金内壳来抑制共振
耳塞本身设计非常细心，这使得大多数人都可以稳固地佩戴它们
并且线材上也使用了特殊材料来减小噪音和听诊器效应
M7和M9都自带4.4mm平衡线
这条线是为众多高级播放器包括索尼自家的Walkman系列准备
M9内置5颗动铁单元，而M7有4颗
少了一颗额外的高频单元
这颗缺少的单元使得两者在对比时有了相当明显的区别
虽然两副耳塞在人声频率区间内频响都非常平直且准确

Meet the IER-M7 and M9, Sony’s multi balanced
armature stage monitors.
While Sony created these IEMs with professional
musicians in mind, their practical, comfortable
design will appeal to music lovers of all
kinds.
The outer earpiece housing on the M7 is made
of plastic, whereas it's magnesium alloy on
the M9.
But both earphones feature an internal magnesium
alloy bracket to supress resonances.
The earphones themselves have been thoughtfully
designed for a stable fit in most ears, and
the cables feature materials to help reduce
cable noise and microphonics.
Both the M7 and M9 also come with a 4.4mm
balanced cable, for use with a variety of
premium audio players including Sony’s own
Walkman series.
The M9 has five balanced armature drivers,
while the M7 makes do with four, missing out
on an additional high frequency driver.
This missing driver is quite obvious when
comparing the two - while both earphones sound

但M7缺少了一些乐器的细节，比如在弦乐和大擦上
即使M7的单元依旧是明显的快速并且响应灵敏的
其钝化的高频最后使得这幅耳塞的声音一耳朵听起来慢速且拥挤
这种调音手法和铁三角在ATH-E70舞台监听耳塞上使用的手法很像
我认为虽然这种高频的滚降很适合舞台监听耳机
因为你可能会担心大音量下过量的高频
但对于常规聆听，你可能觉得这种声音有些呆滞
现在说说M9，这颗额外的单元关系重大：
切换的瞬间你就可以听到所有丢失的细节和优势
M9经常被和Campfire Audio的仙女座进行比较，并且这是一个有益的比较
它们的声音很相似，但我会说M9的低频更厚
并且高频更亮，这使得它的声音更有激情
但是和仙女座自然顺滑的声音比起来人造染色也更加明显
它们所能提供的细节量和结项水平都差不多
所以在哪一个更好的问题上是因人而异的

English: 
decently flat and accurate through the vocal
frequencies, the M7 lacks detail with instruments
like strings and cymbals.
Even though the M7’s drivers are still clearly
fast and responsive, the blunted high frequencies
end up making the earphone sound slow and
congested on first impression.
This is similar to the approach that Audio
Technica took with their ATH-E70 stage monitor,
and while I think this kind of rolled off
high frequency sound works well for stage
monitors where you might be concerned about
excess treble energy at higher volumes, for
regular listening you might find the sound
a bit dull.
Moving to the M9 now, and that extra driver
makes all the difference: suddenly you can
hear all that missing detail and edge.
The M9 is often compared to the Campfire Audio
Andromeda, and it’s a useful comparison
- the sound is very similar, but I would say
that the M9 has a thicker low bass tone and
more shimmery high frequencies, giving it
a more exciting, but more artificial sound
compared to the natural smoothness of the
Andro.
Both have similar levels of detail and imaging,
so it’s really going to be up to you which
one you prefer.

Chinese: 
记住一件事：和低阻高敏设计的仙女座相比
M9远远没有那么挑前段
对于M9而言，平衡线是赠送的附件
然而对于仙女座来说是额外需要购买的
所以我推荐所有来我们店里试听仙女座的人
都应该也试试M9
反之亦然
我是Minidisc TV的Lachlan
我们下次再见

English: 
One thing to keep in mind is that the M9 is
far less picky about what you plug it into
compared to the low impedance, high sensitivity
design of the Andromeda, and the balanced
cable is an included accessory with the M9
whereas it’s an additional purchase with
the Andromeda.
So I recommend that anyone who comes into
the store to demo the Andro, should also give
the M9 a listen.
And vice versa.
This is Lachlan for MinidiscTV.
We'll see you next time!
