Finally got my Philips Fidelio X2 yesterday. Ordered this last December when it was on sale. Had to use a forwarding company to have it shipped here in the Philippines.
So far, everything's good! No channel imbalance (not that I can notice), no funny/toxic smell coming from the headphone, the pads looks good (except for those nasty glues).
Tried a couple of my favorite songs and I was immediately impressed by the sound quality! Man, this was made for Pop, R&B, and EDM! Good thing I was listening to those genres the past couple of weeks.
Literally plug and play. Out of the box it sounds great already.
As for the power (my normal listening volume), it's already on maximum volume on my iPhone 6. On my Galaxy S4, it's 2 steps before maximum volume. Haven't tried with my Clip Zip yet.
I seriously need some hard case for this.
