Assembly was easy and I can tell they used solid materials, manufacturing, and finishing methods when making this product. I gave it 5. hey look a little sturdier where you plug into your phone or iPad, which makes me think they will hold up better. These looked decent and I figured Merrel is a good brand. 1st quality products. I am a little hard of earphones so I do not spend a lot of money on them and expect to go through them after a lot of use during various types of exercise. Only had the headset a couple months and the left side is now broken and will not produce any sound. At least these are WAY more comfy than traditional flip flops. The sound-grade is awesome, but the buds don?t stay in your ears. Definitely great for kids or as part of a decor accent.
