How to Secure "Headsets" (AV Materials)

[Umesha]

Dear Professionals,

We have nearly 300 Headphones in our library and it's in the different levels. Our books and other materials are secured with 3M RFID Tags.

Is there any other way to secure Headsets with more durable way? Like Pigeon Clip or any other security tags (Since RFiD tags needs to be rolled and it doesn't work.)

Kindly give suggestions dears.

If anything is added in the pieces of advice would be completely hypothetical which may be irrelevant to the subject.

Please read the technical documents(Product Manuals) provided with headsets. 

Thank you.
