Its held together with some really cheap, easy to strip screws. For nearly half the price you get every single feature present and at full functionality with the dual sim capabilities! I get lots of compliments on them and people are surprised when I say they are Crocs. Was having problems keeping the comply buds in place. They did just fine. Pressing the mute button on the side of the microphone doesnt unmute it either, until you plug in the microphone. These, in a 7, were too small and the 8 was fine if a tad wide. The memory foam flattened but didn’t bother me. I needed gold sparkly shoes for a wedding I am in and I tried on a ton from all different stores trying to find ones even remotely comfortable with no luck. Plus the 1/4 " plug option lets me plug into the 1/4" headphone jacks of my Roland GR-55 guitar synthesizer and other headphone jacks without an adapter, and leaves a side free to get creative and do seperate/combine vocals and/ or other music to play along with.
