u1s1，2k ltpo加789光学防抖加无线快充还有长焦镜头，1200还是值的。问题是一加9的3799不值... 如果一加9是2999，在这基础上pro加1200就香爆了。
曾经我也是你这么想的，知道在现实生活中知道了一个流量明星的粉丝后，逐渐了解了他们的行为方式和购买力。简而言之就是你可以认为她们养了个娃或者说供了个没收入的爹，只不过这个人她们并不能实际接触到，但花销是一点没少。从孩子/老人的身上能赚多少钱，就不用我多说了吧？
“与普通版的心脏（驱动单元）是一样的”这句话有问题吧，应该正是因为单元不完全一样所以才会有3种不同阻抗的型号，且高阻抗版本的音质如果匹配得当会比低阻版本更好。
“The impedance of a headphone is largely determined by the driver’s voice coil, and for Beyerdynamic’s high-impedance models the voice coil’s wire is super-thin, just 0.018mm, half the thickness of a human hair. Beyerdynamic’s Senior Product Manager Gunter Weidemann explained…
The thinner wires have more windings (layers of wire> on the voice-coil than the lower-impedance Beyerdynamic headphones, which have thicker and heavier, easier-to-manufacture voice coils. The lower moving mass of the 250- and 600-ohm headphones’ voice coils is lighter than the 32-ohm models, and the lower mass is part of the reason high-impedance headphones sound better. The smaller diameter of the 600-ohm voice coil wires allows the wires to fit tighter, so there’s less air between the windings, and that makes the electromagnetic field of the voice coil stronger. All of that reduces distortion for the high-impedance versions compared with the low-impedance headphones.”
