Really great carrying case
This was a great purchase for my CX PLus, Sennheiser Earbuds. The case itself is pretty sturdy and fits perfectly my earbuds. Plus, the small meshed pouch that it has on the lid of the carrying case, is the perfect spot to carry small items, such as the charging cable, or an additional pair of wired earbuds. It offers a pretty decent protection to the buds charging case, as well as offering an included anchor point (carabiner) to attach it anywhere on the go. It comes with a soft interior that protects the case from scratches or accidental bumps. The only downside is that it does add quite a bit of extra bulk to the already big case of the earbuds, but it is a small sacrifice compared to the protection and QOL it offers.
