Keeping their low price in mind, you get a lot of features for your money with the Ozone Oxygen headset. The bundle is great and the headset covers all basic functions well. The build quality is also better than you would expect, and you get a sound quality that can satisfy you in most scenarios. These are not crazily detailed, like the much more expensive HiFiMAN in-ears, but they do alright, producing a lot of bass, which is important to a lot of people. Bassheads will feel right at home with the Oxygen headset, but the midrange is no slouch either as it can definitely be compared to the Sennheiser CX300s in terms of detail. The microphone is adequate and performs well in places that are not too noisy, and the remote works alright but only has one button.
