I wanted decent sound with good balance between lower and upper ranges. Eso sí, como el sonido ambiente se incremente un poco (coches circulando, por ejemplo) ya hay que subir el volumen para poder oir correctamente. She can put them on independently, and it makes getting out the door much easier. i bought them to be used while at work on my work pc to listen to music,chat with others, video meetings and voip calls. The sound is AMAZING and the color is perfect. I was surprised how hard it was to pull the tip of as I had to switch one side to a larger size, but I managed to get it done without breaking anything. Going to purchase a few more in different sizes. Theyre much more comfortable. They are too bassy for what Im looking for. These Audio Technica AIR series ATH AD500X have, in the past, set the standard by which I assess the quality of any other headphone/s that I am likely to buy.
