I am pleasantly surprised with this headset. The sound quality is much more expensive units - as far as I can judge - in every way. According to the manufacturer, these headphones are designed especially for smartphones, laptops and desktop computers. It makes a high quality impression and looks chic. Also to the voice quality of the microphone to be very good as my telephone partner have been reported. I consider the product in terms of price-performance for good and can only recommend this.
