The new Sony MRD EX650AP now have something other Eartips. The gums are now properly kugelrund. At first I thought they were too thick for my ears, but not at all! They fit perfectly to the ear, close really well off, suppress some noise from the outside and, thus you can hear the music much more intense. It's as if you press the handset a little deeper into the ear and bulkheads by all disturbing noises from.
Even the Bose IE2 my brother can not keep up, as he had to admit unwillingly since.
Suddenly I hear quiet sounds, treble, mid and bass that were not there with my old in-ears. Overall, the Sony-MRDEX-650 loves the highs and mids more than the bass. They are there, but who is waiting for the heavy bass, which should set the player as long as possible.
The body and the expanded sonic paths are the EX650 completely made of brass - which is opposite the EX450 from aluminum - and thus heavier than the plastic or aluminum otherwise mostly used. Since in-ears are tiny but anyway, the falls do not "significant" ;-). Due to the higher weight vibrations are to be prevented.
The driver of the headphone is a newly developed 12-millimeter-EX driver to improve the sound.
The here Rated AP version has over normal headphones still an in-line microphone and a remote control, so that even hands-free mobile phone calls is possible.
Conclusion: A great in-ear headphones from Sony, with a very good fit in the ear and thus a pure sound on or in the ears.
If you're looking headphones with clear sound and an extreme comfort studied, which is right here.
