Before buying it, I tried the Marshall Monitor, the Fidelio L1 and AKG 451. But finally, I did not mobile use of a helmet so as to take a sedentary helmet. From there, the congestion has more or insulation, as at home, listening to music through headphones on the sofa.
So here I go for the X1, bcp object too expensive initially but a flash sale enabled me to have nine to 149, a great deal.
I'm not an expert so I will not go into a technical description of the sound I hear. But what I hear sounds perfect, the sound is clear, the music around us, it only remains to close his eyes. As against the neighbors enjoy your music if you listen a bit much given that it is an open helmet. At the same time, this construction gives the best sound. You can not have everything!
The headset comes with a beautiful cable three meters. I bought a cable longer than 1.5m when I plugged in my computer or tablet. I have a small head but it fits perfectly.
I listen to my music mostly on a Yamaha amp but especially with my tablet, which communicates with a NAS where I have all my music in MP3 or FLAC files 320. Take obviously very good because otherwise you can hear everything on.
