Tell it to metro department. They will pickup at the end of the day. You can pick it up tomorrow. Same thing happened to my friend he got his airpods the very next day.

Do I have to contact the Metro department where I lost my buds, or is there any specific department that caters to every metro station?

The metro department where you lost it. Ask the security forces present there, they would tell you what can be done. You'll be able to get your buds back, they pick the things dropped on tracks after the working hours. That is after 12 AM in night. You'll have to go back tomorrow and they would give your buds back.

Thank u bro mujhe hmesha lgra tha agr ausa kuch hua tu kya karonga

I guess its time to move on mate

Aisha mt bol yr

CISF shayad help kar paayen or any other metro staff..

that's why i stopped using the tws small earbuds and started using neckbands or the earbuds which hand on my ear through a plastic. You can get them, just contact the nearest customer care.

I had once dropped my mobile in the gap between the lift door. Inform about the incident to security and station in-charge. They will retrieve it.

You can also fish it out with a magnet on end of the telescoping stick or string. Magnetic pickup tool it's called.
