Below are excerpts from the review:
Simply put, I believe that ddHIFI really cares about its customers and introduces well-thought-out and functional products. C100 is a universal and still small travel organizer for every audio lover like me. I like the comfort and safety I get from using such a gadget. What I would change in the future is definitely a detachable carabiner and a more uniform design. Personally, I highly recommend this product.
