Have been using Grado SR80X for a few months now. After getting used to the 'Grado sound' i believe this is my kind of tast. These are quite compact on ear headphones, wich i prefer when listening outdoors. This is true Handcrafted Plastics® made in Brooklyn, USA . Own also other, bigger, more expensive headsets, but this Grado is the most used, not only the sound but also the small form factor.
Wondering of their higher priced models are worth an upgrade, i.e. GW100x, SR225x
