This headset is really great! I did not know the NGS brand before this purchase and I'm really not disappointed. It is comfortable and can be worn for hours without feeling gene, the sound is really excellent and the bass is present and really good quality! Last I speak of autonomy ... bluffing! I had counted on about 3-4 days and I'm happy to say I reboot the only two once a month! For everyday listening at least an hour! In short nickel!
