The Koss KEB40 is an earphone launched by Gauss. It is relatively rare in China. It uses 9mm Dongquan Hope and aluminum alloy shell, which has a good texture and is also very slim in shape. The parameters are 15Hz~20KHz frequency response, 16 ohm impedance and 104dB sensitivity. Low frequency sound is strong.
The Koss KEB40 is currently at a low price of $9.99, and the coupon "EMCPWWF66" can also be discounted to $4.99, which is about 40 yuan. It is appropriate to make up the order. Taobao in China seems to take off at 300, but the price advantage is obvious.
