Sennheiser Amperior Blue is an upgraded and optimized version of Sennheiser's legendary HD25. The mobile phone and walkman are optimized to reduce the impedance for better driving. The performance of 18 ohm impedance and 120dB sensitivity on mobile phones is enough. In addition, the appearance is dazzling enough. It's quite good to carry something out on the street.
Sennheiser Amperior Blue is currently at a historical low price of 127.95 US dollars, about 773 yuan, and the received price is about 850 yuan. The same model is still in the rhythm of 1873, and the same model in China is still 1500+, so the price advantage is obvious.
