The B & O Form 2 is a lightweight headset. The wearing comfort is correspondingly great. I used this headset for 3 years every day while jogging. He fits perfectly !!! The sound is very good. But you need a device with a very good headphone output (eg Onkyo amplifier or B & O stereo)! On an iPod touch these headphones sound disappointing. This is, however, the Apple product !!! Connected sounds to a notebook with useful sound card, or better on a hi-fi system these headphones very well. The bass is crisp, the heights pleasantly neutral. Even on a smartphone like the Nokia Lumia 720, the sound quality should be evaluated well with, especially since this smartphone also supports WMA Lossless files (uncompressed).
In summary:
Positives: + Very good sound (on a device with reasonable headphone output) as measured by the price! + Extremely comfortable + Design and material selection (aluminum) + Weight + Warranty (3 year international warranty B & O) + Remote control for Apple devices (in the form 2i variant, for example, volume settings or select the next track) + Robust (me fall several times and I'm stuck with the cable !!!)
Negatives: - Headphones can not be folded => therefore quite high space consumption, when traveling
