I purchased this helmet there are 3 weeks to use them in the exclusive setting of multi video game. It fulfills its task to perfection: from circumaural, I can keep it on the head for 10 hours straight without feeling any pain. And yet I have big ears. It is becoming relatively light and foam headband -like those dedicated to Earrings- is of good quality. The microphone function finds no fault either: the sound is crystal clear, either as a transmitter or as a receiver, since I tested the headphones with a friend who also bought. Having cast off the microphone allows the cut which is very convenient, especially to avoid polluting the conversation coughing and sneezing other. The distance from the microphone to the mouth is ideal: you can drink, eat, etc. without being at all embarrassed, and especially without the stain. It's well thought out. The audio function does not suffer any fault. The sound is perfect. But I remember that this is a helmet dedicated to the game. It is clearly focused on quality mids and highs, while the bass is significantly down compared to a classic audiophile. It can be used for listening to music or watching a movie, but only in troubleshooting. The volume is adjustable via a well made directly dial to the right atrium: functional and effective. Open type, note that you will hear your entire soundscape. Even the distant sound of refrigerator compressor is noticeable. In this view, it is absolutely perfect, if indeed we wish to continue to hear what is happening around us during the game. The overall weight of the helmet, though light, is rather unbalanced. He tends to look a little micro side when it is put, because the left slide exiting the headband down a little easier because of this light-weight against. Note that I'm not saying that the atria lean over the head: it is actually the headband that will end very slightly eccentric to the left. This worries simply rule correctly position the helmet after turning on the head. The cable is long enough to allow most of the things a big player needs: turn around the PC :) It is thick and seems really strong. Finally, if the qualities audio / microphone all are indisputable and make this helmet a product price / quality very good to me, it seems a bit fragile and I wonder how it will stand up to time and especially with falls that it will suffer. I would also have wished that Sennheiser provides a storage medium. This adds to the fragility of the whole as a non tidy helmet is damaged more easily. In conclusion, if you are looking for a quality headset to a lot of games in a quiet sound environment, look no further, the PC 320 is definitely the best investment at this price!
