I did read somewhere that an amp would improve the quality if you do choose to do

If your looking fo a lot if base this is not the kind you will like to get but its a good rich clear quality sound

The pictures do not do this headphone justice, it screams quality, durability and elegance

Their comfort level is excellent, build quality is very good, box and accessories are nice

While the sound output of the devices of course varies considerably, the quality of each was vastly improved with these headphones.

Sound quality is very, very good.

The sound quality of the SRH1840 headphones is superb regardless of music genre

As you can see from the tracks listed at the end, I verified that these have good sound quality with any music style

It is hard to explain the immediacy of the music and the clean quality of the sound
