Makind a Headphone Holder
Amplifiers, CD players, speakers, and the like, all have their own specific place on shelves or stands, but when it comes to headphones, they tend to float from place to place, often getting in the way when not in use.
The answer is to invest in a headphone holder. An inexpensive proprietary headphone holder will cost around £10 on the Internet (high street stores are unlikely to stock them), but a simpler, and possibly more convenient, solution is to check out your local DIY or £1.00 store and buy a suitably shaped hook.
The one I bought cost 75p and is, arguably, better than a purpose-made headphone holder.
Keeping headphones on a hook is a convenient, and safe, way to store headphones, and can free up valuable space on your shelf, desk, chair, or any place your headphones usually reside!
As with any protruding object, take care to position the hook in such a way as not to present a danger to others.
