Very good In Ears!

The sound is very transparent, the spatial representation of very well. The highs are strong, almost too strong, but only almost.

The sound is perceived 3x as good as with my Sennheiser IE8 which I have unfortunately lost after many years. The Audio Technica M50 as well as the 180 in ears of Sony (my brother) be exceeded.

Vele In Ears attenuate the highs slightly, that is not the case for the HP20. They come almost approached the Brilianz of the studio monitors Event Opal. Who mid-heavy in ears like is the nad Viso may not operate perfectly, at heights must like to like the Nad Viso.

The Sennheiser IE 800 are still a bit clearer in sound, but sound it boring (like in an empty echoing room) is heard at the Ie 800 each instrument individually strongly separated.
The separation of the HP20 is amazing up close to the 800 Ie.

The cable is sufficiently long and flat. The jack connector is angled. Whether that is so like a matter of taste.

Making calls with the microphone works fine with very good sound quality. The middle button on the headset works with several Android smartphones easily. At first I thought, I do not need the button, but when you get used to it, he is here to stay. Apple users still have volume buttons in addition to the selection.

Due to the enormous size of the look Viso's about 1-2 cm out of the ear. If one side leans his head, that disturbs.
The assortment of Gel-nipples is big enough and you findetfür each ear the right fit.

That one not wearing suits, may from time to time occur (in Allen In Ears) and is then unfortunately personal bad luck and no design flaw ... ears are now times very different.

The magnetic shield of the cable is very weak and you may hear the arithmetic of the processor from the phone when not playing music, and the cable is located directly on the phone.

The sound insulation is better than in many other In Ears.

On the whole, I am very satisfied with the Nad Viso HP20. For double or triple the money you get is not necessarily better sound quality.
The Nad Viso are a secret and it is worthwhile to test them.
