you can hang it up.
Buy 1. IKEA Bastis hook: These IKEA hooks aren't designed to be headphone hangers, but they sure do a great job as some, and they are super affordable. For instance, this Bastis hook is only $2.99! 2. IKEA Bjarnum hook: This steel hook folds flat when not in use. Pairing this with some strong mounting tape might be a winning combination you can attach to the side of your monitor. 3. IKEA Komplement hook: For a tidy and simple under-the-desk solution I see no reason why this Komplement hook designed for clothes hangers can't also hold a pair of cans. 4. Machook by Workerman: You can't go wrong with the simple wooden design of this Machook, designed to fit over an iMac DIY 5. Corrugated Cardboard Stand: There's lots of possibilities with cardboard - as long as you have the patience. I admire the commitment it took to craft this great headphone stand. 6. Lego Technics Stand: What's cooler than Lego's? Maybe Lego Technics if you want to craft a crane-arm headphone holder. The gallery in the link breaks down all the pieces you need to make your own. 7. IKEA Hack: Hacked together from IKEA parts, this headphone holder stands upright and even has cord management built into it. 8. Banana Hanger: Want a simple DIY? Try this one out. Step 1: Buy modern steel-finish banana hanger. Step 2: Hang headphones instead of bananas. Done. (Images: 1. Gregory's Refreshed & Refreshing Home Office, Others: as linked)
