These might not look it but they are solid as a rock, very high construction quality.
The storage arm folds up when not in use and secures well so you don't have to worry about getting snagged on it. The arm is also very well padded where it is in contact with your headphones, so no need to worry about long term wear and tear.
Can also be adjusted via included tools to mount on a vertical surface.
Mounting clamp is dependable and easy to use.
Really happy with these, keeps my nice Sennheisers off my desk and out of harm's way.
