之前美國好像都是跳beta
westone的動圈耳機 有人說是低音加強版的UM1
mmcx耳麥線控 運動用 防水 夜間反光線身
可以參考head fi的review:http://goo.gl/jfQ9CP
節錄一些重點大意，英文不好請指正
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
耳機的結構優越 強力結合舒適 隔音 耐用與重低音的耳道式耳機
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.
整體的聲音非常厚實，強調中低頻
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.
低頻非常緊實 下潛很深，算是這隻耳機的代表頻段
Vocals are not anything to write home about. They are there,
but the ADV has a tendency to make vocals sound distant and dull.
人聲不太行 較遠且乏味
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.
這段蠻有趣的，作者很隨意的開的itunes 的bass reducer EQ
聲音竟然變好變圓滑了，上升至願意花200鎂（原價)買這副耳機的等級
作者的評論是單體夠好但是調音太偏
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.
在這樣的調音下 自然樂器的聲音（尤其弦樂器）會聽起來較無生命
另一方面 合成樂器的聲音就有較好的表現
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.
結論：適合這副耳機的人
1.喜歡低音
2.常常處在旅遊 吵雜的環境
3.重視配戴舒適度與耐久度
4.希望在黑暗中比較容易被看到（因為線身有做金屬反光 夜間跑步配戴較安全
5.你有200鎂可以揮霍（現在是4590 XD)
大家參考看看囉
