1.1.关于一代线和二代线的优劣。
官方的说法我也贴在下面。
What’s new in V2?
1) It is almost 50% lighter and about 20% smaller than the previous version, making it more comfortable. This change was made based on user feedback from the Head-fi community.（更轻更小）
2) Fully balanced headphone amplifier! - The new Cipher V2 has been designed to operate in fully balanced mode. This means that the cipher V2 delivers double the voltage swing for greater output levels.（全平衡耳放）
3) Improved DAC and DSP sections - Improves on the already good Amp and DAC for a more transparent sound and adds an even more powerful DSP. Sample rate and bit rate support remains the same.（更好的DAC和DSP）
4) New Apple LAM2 chip platform - It also uses the new Apple LAM2 platform for better efficiency and lower power consumption.（更省电）
5) Dual microphones -- It has two input microphones for clearer voice calls. And the iSINEs were already recognized has having the best call quality of ANY made-for-Apple headset.（双麦克风）
6) Four buttons - A fourth button allows you to mute/un-mute the microphone during conference calls. This is also programmable for additional functions in the future.（增加的第四个按键支持静音麦克风且未来可能支持其他功能）
当然有很多老哥听了以后觉得一代线更好听，二代线就是辣鸡，但是事实上二代线的硬件完全是升级的，同时改变了预设的eq，其实你只是喜欢一代线的预设而已。根据我的测试以及国外论坛的评测，一代线的预设高频会更多一些，总体听起来更刺激，这也说明了为什么很多一代线用家在听了二代线后一耳朵不喜。
这仅仅是奥蒂兹官方在经过更多测试以及听取反馈后对风格的取舍，你也完全可以把二代线通过Audeze HQ这个软件调教成接近一代线的声音（总体思路就是增加高频，外网论坛有具体参数就不赘述了）。顺便说一句，一代线的做工和品控极差，重量令人发指，美版在更新二代线的同时允许老用户花60美刀买二代线，且将一代线早早停产，结果在国内反而被奉为圭臬，实在有趣。
