At the price, there are no issues with the sound. Although there is noise reduction, it is insufficient. Moreover, you can download a specific headphone application. You may play around with the equalizer settings, personalize each earbud in great detail, and check the battery life of the case and earphones. As was already said, the case's cover is one of the drawbacks. I won't say it's totally terrible, but the way it was attached to the case does not give me much trust.
