Design and features
Kudos to the designers behind the C5s. The earphones exude a high-end quality of design with an artful tungsten/aluminum finish and feature a seemingly sturdy build quality, though we prefer an L-shaped plug to the standard slim one found at the end of the C5s, as the slim nature of the plug makes it easy to use with smartphones covered by a protective case.
The first thing you think when you look at that Secure Loop design is "Wow, that's pretty cool." What makes it cool? Well, it looks so simple that if it indeed works, you wonder why someone didn't think of it sooner.
As the company says, you can adjust the loop, adding or taking away from its size by simply pulling or pushing on the cord.

It works a little differently with the Secure Loop--first, you get the Loop to tuck properly into your ear, then you have to get the tip jammed inside bowers and wilkins c5
