    First-time Review


    First product I bought from this company, sometimes last year, all the other earbuds I got kept going dead within weeks to a month. Will admit the others were from a grocery store, so they were bound to be the throwaway type. Been using these since I got them, and compared to the others, they were well worth the price. Sound quality was great, had some prior run-ins with some earbuds that just sounded like garbage. Fit nicely into my ears, there was one pair I had that actually gave me an ear pimple -- Weird, I know. Plus those were just uncomfortable on top of that. These have faced much snagging like absolute champs, only recently been facing issues like having to hold them a certain way, but those issues seem to fade soon after they come. And both ears still work just fine outside of that! Left one's the first to start disconnecting at times, but just a little bit of position adjustment to get them going again. The earliest issue I found with these was that the cover for the adjustment buttons fell off, resulting in no longer being able to push any of them. Not that there's much to worry about there, as all the systems I've used them with already have their own ways to adjust the volume. Biggest loss was just the middle button which allowed skipping through songs without turning on my phone, which isn't too big of a deal. All in all, well worth the price for what I came accustomed to prior to getting them.
