    These speakers are awesome.
    Great sound and easy to install and operate. Rode 2 days of DH in the rain and did not have any issues.

    A great purchase
    I opted for these due to the knob and big button so I wouldn't be fumbling with anything small with my gloves. I love those features. It's got great sound and I can hear it even on the highway and at speeds of 130+...

    Great sound and solid product
    Pros: Solid bass. Clear highs. Easy install. Stupid simple slim controller. Built-in mic. Waterproof..
    Cons: Shipping took longer than expected. Ordered overnight shipping on Sunday night, and didn't receive package until Tuesday morning.

    I love these speakers. Sounds great!
    The knob controls are easy to use with gloves, and at highway speeds too.
