Right said matebennysachdev said:The HD555, AD300, M35 fall in the 50-100$ bracket, so they fall under the same range. The shift from one headphone to the other will not be a major improvement as such but rather a shift in the sound signature.
The AD300 will have a better soundstage owing to the open back nature of the hp and the M35 has a better bass owing to the isolation and closed back nature.
So if you want more bass, go for the M35, if you want a bigger sound and more clarity, go for the AD300. Personally i feel they both would be an improvement over the HD555 but YMMV. Both are very good headphones at a good price.![]()
