Alpine Muffy Kids Noise Cancelling Headphones Hard Carrying Case - Durable Protective Travel Storage for School, Airplane & Home Use

So far this is exactly what I needed. I got a pair of 3M work tunes and I wanted to keep them from getting wrecked around jobs and while getting carried in a tool bag. They fit fine, you have to slide in the height adjuster deals, but not a big deal. I recommended the case to my dad already. It is a fairly hard shell case, I think it will do the job well.
