Thank you for viewing. I purchased these about a year ago, but I haven't used them much and have kept them in storage. Regarding the included earpieces, I've lost the M size, so I've attached a third-party one. The S and L sizes are the original ones. Other items included are the instruction manual and the box. The following is an explanation by AI: High-quality hybrid configuration earphones, convenient with a remote control and microphone. - Model Name: SE01 - Brand: SoundsGood - Configuration: Hybrid (1BA+1DD) - Remote Control/Microphone: With remote control and microphone - Hi-Res: Hi-Res compatible Thank you for viewing.
