I bought one brand on Lazada, don't remember which, and the straps on them were not applied correctly and they kept breaking off.
Currently I bought some of the Double A brand. They are well constructed. My only complaint is the straps hurt some on the back of my ears.
On Lazada and in a lot of stores they have the 3D mask brand. Instead of the elastic ear strap they have a soft material ear strap. 7/11 carries them.
