    Previous model was better (OCX685i)

    After having the OCX685i for a few years and loving them, I was disappointed when the cabling deteriorated and cut out on one of the ears. So I bought this new model (after also trying CX686G) hoping they would be superior. But after a 9km run I was disappointed. Initially, they felt fine, but after running, I could feel they weren't as snug as the previous model , and they kept sliding out . I even tried the small earplug size but they didn't feel right. I don't know why they changed the design as the previous one was so much more curved and comfortable and never slid out . These feel like they're slightly too big in comparison. I even bought the CX686G previously to buying these , because OCX686G hadn't come out yet . Even with those I was extremely disappointed. Same issue , kept sliding out whilst running. So now I have 2 pairs of these earphones that are inferior to the OCX685i.

    I would not recommend this to a friend.

    not worth the price

    Disappointed. I received these a gift with the hopes they would last longer & work better than cheap headphones. They don't.


    Fit well & sound good


    Broke as quickly as my sport headphones which cost a quarter of the price, despite following care instructions & storing/transporting in pouch.

    Best wired headphones for running.

    The absolutely best wired headphones I have ever used for running. Extremely lightweight and comfortable. No other running headphones compare to the design and quality.


    Perfect fit. Extremely lightweight. Very comfortable. Great sound and durability. 3 distinct sizes to fit all ear types.


    Cord is a bit too long.


    Running. Working out.


    I would recommend this to a friend.
