Ergonomics are good, you feel at ease especially that insulates the external noise (closed headphone type), total immersion in what we listen. In the hands it does not seem fragile. It is also easy to store (bags provided). The sound is neutral (Studio headphones), but also very good for Hi-Fi. The bass is clean, non-garish treble and midrange did not come out too. The whole is balanced. I use it in Hi-Fi to listen to SA-CD, DSD Disc, flac 24bit / 192kHz, CD ... on quality material without audiophile, though :) Also on PC (dedicated sound card) and on my old Yamaha DX7 synthesizer. For the price, you will not regret it! Others prefer the AKG headphones or Seinnheiser following their uses but for a different price. Very good helmet, I'm happy! Fabian
