Im a beginner audiophile and currently the only "serious" cans i own are beyerdynamic DT 770 80 ohm + FiiO E11. Just wanted to ask what headphones should i get next for different sound experience, i mean i dont really realize how sound may vary "v-shaped, u-shaped, dark, bright and things like that", it would be much easier for me to understand the sound if i get to experience opposite sound type of my cans. Im looking for 50-170$ headphones. Grados it is?
There's no reason why not. Get the 80's, Alessandro MS1i (based on Grado) or wait until you have $200 and get the very well regarded 225i. All are easy to drive and can rock your world.
