The sound is pretty good for an entry level product, and even manages to reproduce low enough correct.
In terms of quality of materials, Philips has opted for the cheap, white plastic shell really leaves a sense of fragility. Another negative point, clips for ears that are too firm, a little more flexibility would have made it much more pleasant helmet.
Overall, I am satisfied with my purchase, as long as this headset stays around 10 euros it remains a good compromise with its big brother: Philips - SHS4700
