The product, the packaging is really very good bill, we feel that it is the quality, but there are several points that have disappointed me: - Headphones are quite thick it looks like we have grapefruit halves in each ear, eventually it's not comfortable. -The Faux leather replacement headphones are certainly more comfortable, but the sound is lower and there is less bass. -Insulation: This is the weak point, it's not a headset to use public transport, they are poorly insulated, so we certainly hear the music, but we also hear outside noise that turns into a hubbub of background becomes unpleasant. the insulating effect of the thickness of the pads is sufficient. The ideal use of these headphones is in ideal conditions: In the studio, at home in front of his computer, at work, in short, in a quiet location!
