First, the functionality:
It is equipped at the factory with a headphone according to information provided to 99.9% oxygen-free cable, which is to hold the cable noise to a minimum. This also works fully.
As mentioned above, some confuse declared specialists "cable noise" with the simple transfer of kinetic energy, which is of course the oxygen content of the cable entirely independently.
The customizable in-ear plugs made of silicone fit perfectly into your ear and let the environment almost forgotten; do not worry, you can still hear enough to avoid being run over suddenly while jogging :).
For cable (that in its chic Orange really something fancier) yet there's a clip to attach to the whole of the clothing. The first seems not to make much sense, but is just jogging really useful.
Finally, the headphones are also washable (with tap water) and schweißabweisend- no empty promise which works great in practice everything.
For sound:
The CX 380 covers all frequency ranges from good and offers beautiful clear bass; In general, the handset is good for basslastigere music. Also a variety of instruments mixed the CX 380 is not a half-baked sonic mush, but leaves everything clear Nition 5 of 5 points.
Positive noticed also the significantly increased volume, just outside jogging, cycling (prohibited, but oh well) and a lot of other opportunities is also really great to me.
A small remark nor the way: With the 380 I noticed for the first time I can hear my MP3 player searches the title.
Overall, strong buy recommendation, so long as you have one or two good scissors or knives in the house.
Sure there are better headphones in my opinion but only from 100 up until then will remain of the 380 II without competition among the domestic Ears.
