The headset is delivered in a very noble and high-quality packaging, as it should be at this price but. In addition to the headphones a practical small bag and plenty of Ear Pads still was, all 5 pair in number (very useful because I like this ever verdussel).
From this first very positive impression we went on to the actual device. What is then immediately caught my eye, is the extremely good and stable quality cable. The cable is very elastic, looks very strong and feels very high quality. Finally no longer this annoying cable equalization before you can start. Even the remote control is perfectly integrated into the cable with which you can quickly times a song forwarding on / back, take calls or can pause the track currently playing.
Another very important factor was the comfort for me. Longer times by train Since I'm already on the road or sometimes even like a few hours in the evening with the iPod listening to music, I had that this push for in-ear headphones frequently the problem after prolonged use in the ear. Besides, I had other models the problem that the listener fell quickly out of the ear. Even after several hours, the headphones still feels good in your ears and a long wearing comfort is guaranteed.
Finally, the most important: the sound. What good is a good headset that looks nice, feels good in the ear, but not sensible sounds? However, I was also not left in the lurch the AH-C250. A really perfectly balanced sound. Both treble, bass and midtones are so original play as it can not be better. Live recordings (Toten Hosen, ACDC) feel as if you direct in the crowd are really great!
Those who then prefer more bass-heavy, which can then even rework the headphones App for Smartphone something.
So for the price a real buy recommendation! Headphones from Denon gladly again :-)
