I have a headset searched for the following requirements: Phone: Samsung Note 2 (Android) Music: streamed, ripped from CD, downloads. Music direction: for example, audio books, alarm clock, Melua, rock, instrumental music etc. Listen on the bike, on the train, in the garden, leave. Important to me was good, as neutral as possible, unobtrusive sound. Price up to about 100. Robust, good to handle. Because of tests and reviews I am in this RHA, the Sennheiser CX 5.0 and the Philips Fidelio S2 encountered and have ordered and compared me all three. I then decided to go for the RHA: Sonically, I found all well. Although different were also very different in the emphasis of the various areas (bass, voice, treble, space), but the music qualities and mixes of the title. Once the sound better once the other. Convinced then got me the quality and handling of the RHA. The fact that the cable passes through the ear in back, he sits on the bike very well and I can take the headphones for a conversation in a simple yet from the ear and he dangles somewhere around, but next to the ear. Among the many different adapters fit a couple of very good with me and holds on the bike, even with very bad roads. The cables are rel. thick, no Kabelverknotung. Occasionally I need reprints anyway. The material and finish make a very good impression, subjectively clearly-quality than the other. My feeling is that this handset will last a long time (I can of course after 2 weeks use not really say) and also tolerate rougher handling in everyday life. 3-year warranty can also hope. The stainless steel, unlike plastic like them also best. The higher weight does not bother me. Operation: the RHA are built for iphones. On my Note 2 (Android) works handsfree, the previous song, next song. Quieter and louder unfortunately does not at the counter. Very unfortunate that RHA is so limited here on iphone. That is why a star deduction.
