Fit:
The fit is perfect with the correct size rubber stopper. Since the earphones are ultra-light, they stay where they belong and not slip even when moving out of the ears.
Sound:
The sound is very clear. The highs and mids are clearly preferred, a bass is heard hardly. Even with bass-heavy music it can be imagined more, because listening to.
For calls, the headset is highly recommended, the caller can be heard loud and clear and has no complaints. However, for the great music enjoyment, it is not created.
Conclusion:
A headset that does its job, but leaves no musical enjoyment. Considering the price but perfectly OK.
