I took several copies of this headset for the office, to connect it with a suitable adapter to the headphone jack of my phones. For this use, this headset is very good: - Light and relatively quiet compared to many other stereo headphones, - It brings stereo, compared to a lot of phone headsets. Personally I prefer, - Very good sound quality, both for the operator and for his party (the microphone is noise reduction)
So that makes this headset initially planned for use on PC, gaming and VoIP good much cheaper than many helmets helmet dedicated to telephony.
Next phone models with which it is used, and what they propose as sound headphone volume control, the sound may be a little strong, however, and this helmet lacks a volume knob on the wire or the helmet. For me it's his only fault.
