I’ve been using x3 for a pretty long time. Mostly paired with Beyerdynamic 770 pro 32 ohm. The sound that x3 can produce with this pair of headphones is simply amazing. Recently I decided to try x5, for I though it should be better in sound. However, I was wrong. The sound of x5 just doesn’t work for me.
I ordered x5 with pair of Vsonic GR 07 Bass Edition. I like a little bit more bass in music, and the absence of possibility to change bass in x5 is really frustrating me. In x3 you can easily adjust bass and treble to the level that you need, but in x5 there is just a horrible equalizer that better not use to. For me there just not enough bass, especially paired with Vsonic GR 07 BE. Paired with Beyerdynamic there is pretty enough bass for the normal person, but If you are a basshead person like I am you better go with x3. X3 with both headphones is amazingly super awesome!!! GR 07 BE is so good with x3, and to workout with them is pure pleasure. Mostly I listen heavy music like August Burns Red, Bring Me The Horizon, Her Name In Blood, etc., and a little bit of Dubstep like Skrillex. For that kind of music x3 is epic win. I will stay with x3 and return x5 to Amazon. I thinking about trying x1, and I will write my opinion on that one soon.
