# Tone #
Clear balanced tones. The height could be a bit more brilliant, but I've learned that in other appropriate headphones then then the danger from high-pitched "hissing", eg hi-hats, increases (very uncomfortable). The problem you have here. The bass is powerful and rich. To my mind was unusually strong at the beginning but I got used to quickly and do not want to do without it.
# Comfortable #
This is something which is in many Rezeinsionen of in-ear headphones neglected MMN too. I was friends with in-ears me never, because they were uncomfortable to wear. Symmetrical in-ears that are often seen coming out of the question for me. This Panasonic are asymmetrical and ergonomic: They are based by their shape in addition to the external ear - thus keep better, do not slip out (even in movement) and so probably need less pressure in the ear canal to hold. The rubber elements nestle well to (important for the sound) without pressing - for me at least.
Negative is maybe that the cables make noise when they hit something hard. I do not know if that's a problem in sports, walking does not happen and generally falls infrequently.
# Others #
I have the third headphones of this model. The first I've lost, the second had 2.5 years for a cable break. For the price they are me not too bad to carry them in your back pocket. I use it almost daily also. If one disregards the choice of materials (plastic) and the simple yet solid design, you are in all respects (sound, comfort) better than doing headset more than 40 euros (compared with, for example, N-ergy Monster In-Ears).
I would like to say that I once caught and returned a forgery of this model (in white) (However, in another online portal and they came without OVP). The sound of the forgery was tinny, bass hardly available and they were processed worse. Therefore, be careful. I'll upload a few photos in which I have tried to show the visual differences (with thumbs up for the original, down in the forgery).
Conclusion # #
For the price highly recommended. Keep loose with with headphones that cost many times over. These are my clear favorite for everyday use on the go - on smartphone MP3 players and notebook.
