The package for 'Soundcore P31i' looks like this.
The contents include the charging case, the main unit, a USB Type-C cable for charging, ear tips, a quick start guide, and a warranty card.
The earphones come with medium-sized ear tips attached, and three replacement ear tips in sizes XS, S, and L are also included.

When you open the charging case, it looks like this.
There is a USB Type-C port on the back for charging.
The earphone body looks like this.
It comes with a sheet that says 'Please remove before use,' so peel it off according to the instructions.
The actual size is approximately 28mm in length for the stem, approximately 26mm in width including the earpiece, and approximately 20mm in thickness for the earpiece.
The weight of both earbuds is approximately 9g.
The total weight including the charging case was approximately 59g.
I actually connected to Bluetooth and listened to music on the 'Soundcore P31i'. When I opened the lid with the earphones in the case, the indicator lit up white and the Bluetooth connection was established.
When I opened the Bluetooth settings on my smartphone, 'Soundcore P31i' was listed as a connectable device, so I selected it.
The connection is complete.
This is what it looks like when you actually put on the 'Soundcore P31i'.
The Soundcore P31i allows you to control playback, pause, noise cancellation, and more by touching the earpiece. The default controls are as follows:

When I connected the Soundcore P31i to my smartphone and opened Soundcore, the following screen was displayed: In addition to showing the current battery level, I could also switch between Noise Cancelling Mode, Standard Mode, and Ambient Sound Capture Mode.
Select 'Noise Cancelling Mode' and tap 'Mode'.
You can manually change the strength of noise cancellation, set it to automatically switch noise cancellation modes, or choose from a selection of scenes.
When you select the ambient sound mode, you can hear the sound as clearly as or better than when you're not wearing any earphones.
Open 'Controls' at the bottom to customize earphone operation.
You can assign actions to each of the left and right earphones: 'tap once,' 'tap twice,' 'tap three times,' and 'press and hold.'
When I actually tried out the Soundcore P31i, I found that they were so light that I almost forgot I was wearing them unless music was playing, and they also had excellent noise canceling and ambient sound capture capabilities. When you turn on the ambient sound capture mode, you can hear outside sounds while listening to music, just as if you weren't wearing earphones. They also feature a large 11mm driver, which delivers powerful bass.
