    Good sound, weak durability
    3 Stars
    Good sound, weak durability
    I think the big thing to note here is how easily the earbud rotates with respect to its housing. Because it is inadequately secured, I found myself having to constantly rotate it so that it sat correctly in its original configuration. It would get messed up if the earbuds got yanked out of my ear for whatever reason (usually cat). This quickly resulted in the earbud coming entirely detached from the base held on by nothing except the two wires that send the signal/power to the little speaker in there, which inevitably led to a loss of sound, and so now it's just all the way broken.The sound was pretty good, totally satisfied with that. Just the durability is subpar. I have had a lot of earbuds in my time. These earbuds are less durable than most of the earbuds I've had. Below average durability. Given the price, I can't recommend them. If they would have lasted a year I would have had no complaints. They didn't. Therefore, this is my complaint.
