    Incredible Sound and Performance

    Never would have thought a single driver could sound this good. With a good seal the treble, mids, and bass are distinctively clear. I purchased Samsung buds a couple days prior and they sound terrible, but these have some incredible sound engineering at work. Would purchase again in a heartbeat. The carrying case is small and the buds function well.

    Disappointed with the quality of this product from this brand. App lacks good tools to set sound quality. Bass is OK and highs are crisp.

    These are nice but I expected better given the price. I’ve been in areas where it was loud around me so in that situation I expected these to do well with cancelling noise. I like that they have an app to customize controls. That’s helpful. I highly dislike that there the right earbud has to be off the charger so that the left can work. Sometimes I prefer the left earbud rather than the right when I just need to use one. Super inconvenient and risky. I bought skull candy earbuds for $60 that work watt better. I wouldn’t recommend these really.

    Historic brand, disappointing buds. Clunky shape, inconsistent touch controls, moderate to poor audio. Glad I got them half off or I would feel burned.

    They have become my favorite earbuds now. Besides there is no active noise-canceling, these buds have all the features daily earbuds users look for. Another thing is they do fall out my ears a bit easier than I expected. They fell on the concrete ground once without being damaged. So I was naturally happy with that.

    These are great Bluetooth buds. I would just be weary of purchasing this brand the companies sound portion of the company was sold off to a hearing aid company so support may be lacking over time. But if you don't care about warranties and you want a solid earbud set go for it.

    Sounds great. They were perfect up until now. They stopped working today so we'll see how well the company handles the 2 years warranty. Bestbuy didnt offer a warranty so i just submitted a manufacturer warranty repair request.
