Easy to assemble and stable. Certainly and personally not worth the $15. I have many such bluetooth headphones. This monitor headphones doesnt have a very strong bass, but they sound really good. am usually a Size 9 and it was the Cinese size 44 that gave me the necessary toe room. I have given only 3 stars because I have purchased the headphones especially to talk over the phone and it isnt as good as I expected. Thanks ASTRO for always delivering! apartment is full of wool. They all break at the spot where they join the band to make a loop. Raising the desk is impossible while using it as the tension lifts the desk off the ground.
