Hello;
270 gbp of grado vs 170 gbp of sennheiser is a substantial price difference to compare the two headphones..
I totally agree! It's a significant price difference!
In addition, the Grado 325's are, by far and away, THE worst headphones I've ever owned, so much so, I had them for about 2 weeks before returning them.
At the time I had the SR60, 125, 225 and Alessandro MS1 in my collection, so I thought the natural progression would be to move up to the 325. I found the sound extremely uneven, and to this day, it's the only pair of headphones I was glad to get rid of.
Fortunately, I rarely pay attention to WHF. Being a bad, commercially driven, entity, WHF wouldn't know a good sounding product if it slapped them in the face.
