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 low price of US $139.99, about 850 yuan, and about 970 yuan. The same model is still at the pace of 200 dollars, and the same model in China is still at 1500+, so the price advantage is obvious.

PS. If you are not so cold about color, you can take a look at this《 Recent low price: Sennheiser HD25-1 II 9 》It seems that they are offering a discount of 10%, and the difference in price is not big.
