1. The cord is too short. Cables for R and L come at the neckline of my V-Neck Shirts together. That is about 3 cm to the neck.
2. The cable is very stiff, produced during head movements and noise attracts listeners from the ear.
3. The earplugs made of rubber do not keep well and often fall off, get lost or remain in the ear plug.
4. The page numbers R and L can be read only with difficulty since it is very small on the cable and is not color-coded.
5. The bag is an impertinence, very poor quality processed. It's too big and without lock option so that
it rises in the bag and the headphones fall out.
I then search the headset that plugs as well as the bag in my gym bag back together.
All in all, for a company with many years experience in the field of earphone, a bad product.
