Negatives:
- By the silicone can not be opened as far as the clip. Attaching the iPod is on thicker materials or a zipper no longer possible (by force it would go, but does not make sense)
- Bottom edges are not protected and the protective sleeve from slipping like upward since this is open downwards
Conclusion:
Not absolutely necessary.
A screen protector should be enough to turn the display to protect it from scratches. I use the envelope only during exercise, as there is a risk that the iPod once dissolves and could fall to the ground. Has one strap headphone is the iPod but also collected by the low weight with no problems and did not fall only so deep.
