Sound:
So who do not give themselves much! clear I give the TopNote the Sennheiser, which sounds just as should be a good listener - unspectacular. Basses are there, where they should be, treble clear that right through audible. especially in demanding music [eg badi assad, Ana Caram] one hears a Fitzelchen more details by. who is more fun? the sony! it does not take quite as accurate with the balance, and provides more bass and treble than are actually there. but "hey", who has not ever the loudness adjuster turned up the amplifier and then happy? nevertheless Sennheiser lead.
Handling:
Sony pushes you in your ear - well isses. In addition, the even adapt to a smartphone [with micro and remote control in the cable]. As easy as that when Sennheiser: there can / want the bass to be adjusted using STEL of larks, the right ear will be selected from various stöpselchen. What I really dislike: the cable dissipation behind the ear, that's for sure intensely listening ok, but "fast times" plug in the headset, which is as annoying. Advantage Sony
Equipment / appearance
brass shells Sony's make difficult thing ago, also the finely fluted cable, and the Brass Studded jack plug. because Sennheiser comes not with. for this is a quality box [but which is rather annoying in practice. in the bag of Sony, the listener is housed faster] and a bit of "tool" here. the number of ear adjustments at Sennheiser is powerful. tie
Conclusion: If you say to yourself "so, the more I listen to music, and the concentrated", which is operated with the Sennheiser top, but has little to expect compromises even when Sony.
who wants to be "just get away and entertain pleasant" on the train, in the waiting room, taking the Sony.
if you also the price [of the Sennheiser is about 3 times as expensive] in the decision involving this should be clearly compared to many. since then the losing of the part not so hurts :-)
