* Ergonomics, the product is pretty good as a whole, the atria and the controls may seem large at first, but they are quickly forgotten. The flat cable is a real plus because it helps strengthen the bond with the skin and clothing, preventing the device from slipping from your neck to regain ground. However, maintaining the ear is not at the rendezvous. Certainly this depends on maintaining forms of each ear, and the product comes with different sizes of tip, but unfortunately I found a big problem: the two headphones are not designed the same way. Where the right fits perfectly (it blocks the ear properly, reducing the parasitic losses and noise), impossible to ensure a proper seal in the left ear. Of course I thought the problem was in my ears, but by simply changing direction, I see the same difference. Impossible therefore for me to get a suitable sound: all bass fuitent of the ear and the rest of the spectrum is overwritten.
* His side, the product is far from satisfactory: the bass is nonexistent, the medium are soft, and treble assault the ear. Although it is possible to reach a reasonable compromise with your favorite EQ, the result is frustrating. Unable to differentiate between tracks, and a kind of soup is obtained, unfortunately.
* Viewpoint connectivity, no complaints, Bluetooth works great and I have no problem pairing with my smartphone (a Sony Xperia Z3 Compact).
To summarize, I guess this is perfect for those who wish to use their sports sessions and / or who do not have special requirements in terms of sound. I do not however recommend it for regular use in public transport or on the street, because the result is disappointing. But I added that for this price range, the product is still suitable. I bought myself because I did not want to invest in a more expensive product at this time, and I use it every day.
