Dear Lenovo users, hello!

Dear Lenovo users, hello!

The headset (headset) plug of the mobile phone is a four-segment structure. Although it is the same standard, due to its different interface standards and four-segment functional differences, it is divided into two distinct camps - the N-version headset and the I-version headset. The n-version of the headphones from left to right are the left channel, the right channel, the microphone, and the ground wire.

From left to right, the i-version headphones are the left channel, the right channel, the ground wire, and the microphone. But the size is the same, and the appearance cannot be distinguished. It is recommended that you bring the machine with you when you buy relevant accessories, and then purchase them after the test is available, so as to avoid unnecessary losses.
