节录一些重点大意，英文不好请指正
In terms of physical construction the ADV is great. I would go so far as to
say that the ADV is the strongest combination of comfort, isolation and
durability in a bass-heavy IEM on the market today
耳机的结构优越 强力结合舒适 隔音 耐用与重低音的耳道式耳机
SOUND
Overall sound is very thick, with a strong emphasis on bass and mid-bass.
Interestingly, it is possible to vary the amount of bass by varying
the insertion depth of the ADV.
整体的声音非常厚实，强调中低频
Bass on the ADV is exceptionally tight and reaches very deep.
Sub-bass is rumbly, taut and immensely authoritative. Audible driver
action starts at 10hz and there is no discernible roll off. The bass is
clearly the strongest and most impressive part of the signature.
低频非常紧实 下潜很深，算是这只耳机的代表频段
Vocals are not anything to write home about. They are there,
but the ADV has a tendency to make vocals sound distant and dull.
人声不太行 较远且乏味
With the iTunes bass reducer EQ the ADV sounds very good. The bass reducer is
a gradual EQ of -1.5 hz at 500hz all the way down to -6db at 32hz.
With the bass tuned down, you can turn the overall volume up and then the
ADV transforms into a nice, smooth and articulate listen that the average
Head-Fier might be happy to pop $200 bucks on. Clearly the driver is good but
the tuning is intensely dark.
这段蛮有趣的，作者很随意的开的itunes 的bass reducer EQ
声音竟然变好变圆滑了，上升至愿意花200镁（原价)买这副耳机的等级
作者的评论是单体够好但是调音太偏
With the ADV's tuning, the timbre is completely unnatural since all
natural instruments (particularly strings) sound somewhat lifeless.
On the flip side the quality driver means that for synthetic instruments
where we have no natural references, the ADV sounds good.
在这样的调音下 自然乐器的声音（尤其弦乐器）会听起来较无生命
另一方面 合成乐器的声音就有较好的表现
CONCLUSION
If you have read this far I think you can tell if the ADV is right for you.
If you are after a bassy IEM, you do a lot of travelling in noisy
environments, you value wearing comfort and durability, you want to be
more visible in the dark - and you have $200 to spare - the ADV is right for
you.
结论：适合这副耳机的人
1.喜欢低音
2.常常处在旅游 吵杂的环境
3.重视配戴舒适度与耐久度
4.希望在黑暗中比较容易被看到（因为线身有做金属反光 夜间跑步配戴较安全
5.你有200镁可以挥霍（现在是4590 XD)
大家参考看看囉
